Description

  The present invention relates to a processing apparatus used for processing such as solid phase synthesis of peptides.

  Conventional techniques include a reaction cell that is permeable to microwave radiation, a passage for adding liquid to the reaction cell, a passage for removing liquid from the reaction cell rather than a solid, and holding the reaction cell. An apparatus used for solid phase synthesis of peptides including a microwave cavity and a microwave source in wave communication with this cavity has been known (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2005-15483 (first page, FIG. 1 etc.)

  However, since the apparatus used for the conventional solid phase synthesis of peptides as described above can only use a small reaction vessel such as a reaction cell, it can only perform a process for synthesizing a small amount of peptide, and it can The throughput of phase synthesis could not be increased. For example, in a single-mode microwave, the location where the microwave can be concentrated is very narrow, so that a single-mode microwave is generated from the outside of a microwave-permeable reaction cell as in the conventional apparatus. In an apparatus for irradiating microwaves, it was difficult to efficiently synthesize peptides by intensively irradiating microwaves unless the reaction vessel was as small as a test tube. For this reason, even if the reaction cell of the conventional apparatus is simply enlarged, the number of places irradiated with microwaves is limited, and as a result, the amount of peptide synthesized by the solid-phase synthesis process is increased. It was difficult.

  The same can be said for a conventional processing apparatus using single-mode microwaves. In single-mode microwaves, the location where the microwaves can be concentrated is very narrow, so it must be a small processing container. For example, it is difficult to efficiently perform desired processing by intensively irradiating the contents with microwaves. Even if a container used for processing in a conventional apparatus is simply enlarged, microwaves are irradiated. As a result, it is difficult to appropriately increase the amount of processing performed by irradiating microwaves.

(Embodiment 1)

  The processing apparatus 1 includes a container 101, an irradiation unit 102, a bulb 103, a filter 105, and a reflection member 106. The container 101 has a discharge port 1011, a supply port 1012, and an irradiation opening 1013.

  The processing apparatus 1 of this Embodiment is a processing apparatus used for the solid phase synthesis | combination which synthesize | combines the peptide couple | bonded with the solid-phase resin. Hereinafter, an example of solid phase synthesis will be briefly described. However, the solid phase synthesis performed using the processing apparatus 1 of the present embodiment is not limited to the solid phase synthesis described below, and may be other solid phase synthesis. For example, solid-phase synthesis performed using substances other than those described below may be used.

  Solid phase synthesis is one of the methods for chemically synthesizing peptides and is also called peptide solid phase synthesis. In solid-phase synthesis, a solid-phase resin is used, a desired amino group is bonded to the surface of the solid-phase resin suspended in an appropriate solvent, and the desired amino acid is further sequentially added to the amino acid by a dehydration reaction. The peptide bound to the solid phase resin is synthesized by binding and extending the amino acid chain. For example, the peptide of interest can be obtained by separating the peptide bound to the solid phase resin from the solid phase resin.

  In the solid-phase synthesis, since the peptide synthesis proceeds from the C-terminal side to the N-terminal side, the synthesis is started by first binding the C-terminal amino acid to the surface of the solid-phase resin. After the reaction between the solid phase surface and the amino acid is completed, the solid phase resin is washed with a solvent to remove the remaining amino acid and the like. After the removal, when the protecting group of the amino acid bonded to the solid phase resin is removed (deprotection), the amino group that becomes the next reaction point appears again on the surface of the solid phase resin. Further, an amino acid whose N-terminal is protected is added, and the C-terminal side of the amino acid whose N-terminal is protected is bonded to the N-terminal side of the amino acid appearing on the surface of the solid phase resin by a dehydration reaction. By repeating these procedures while sequentially changing the amino acid to be used, a peptide having the target sequence can be synthesized with high accuracy.

  An example of the materials used for the solid phase synthesis will be described. As the solid phase resin, for example, a polymer such as polystyrene or polyamide is used. However, the solid phase resin may be a resin other than these. As the solid phase resin, for example, a granular (for example, bead-shaped) resin having a diameter of 10 μm to 1000 μm is used. As the solvent for suspending the solid phase resin, for example, dimethylformamide or DMF (N, N-dimethylformamide) is used. However, other solvents may be used.

  Instead of directly binding the C-terminal amino acid to the solid phase resin, the solid phase resin and the C-terminal amino acid may be indirectly bound via a linker molecule or the like. Examples of the linker molecule include a peptide acid such as 4-hydroxymethylphenoxyacetyl-4′-methylbenzhydrylamine (HMP), or a peptide amide such as a benzhydrylamine derivative.

  As the amino acid protecting group, for example, Boc (Nα′-t-butoxycarbonyl), Fmoc (9-fluorenylmethyloxycarbonyl) and the like are used.

  Removal of the protecting group, that is, deprotection is performed by, for example, a mild base treatment using picrozine or piperidine as a deprotecting agent.

  The process of sequentially binding amino acids to the solid phase resin is performed in a solution containing the amino acids. For example, the process of sequentially binding amino acids to the solid phase resin is performed in a solution containing an amino acid, an activator, a racemization inhibitor and the like. The activator binds the amino acid bound to the deprotected solid phase resin (including the terminal amino acid of the peptide bound to the solid phase resin) with the amino acid whose N-terminal is protected in the solution. Used to promote. The activator is also called a condensing agent. The racemization inhibitor is used to suppress the occurrence of racemization and prevent a decrease in reaction due to racemization. Examples of the activator include DIPCI (N, N′-dipropylcarbodiimide) or HBTU (N, N, N ′, N′-tetramethyl-O- (benzotriazol-1-yl) uronium hexafluorophos. (Fart) etc. are used. Moreover, as a racemization inhibitor, Oxyma (ethyl (hydroxyimino) cyanoacetate) etc. are used, for example.

  In various processes performed in the solid-phase synthesis, irradiation with microwaves can accelerate the process and increase the speed of the process. For example, as disclosed in Patent Document 1 and the like, when removing a protecting group from the N-terminal of an amino acid bonded to a solid phase resin, that is, when deprotecting, by irradiating with microwaves It is known that the deprotection step can be promoted to shorten the processing time. The amino acid bound to the solid phase resin may be considered to include the terminal amino acid of the peptide bound to the solid phase resin. The same applies to the following. It is also known that the condensation treatment time can be shortened by irradiating microwaves when condensing a deprotected amino acid bonded to a solid phase resin with an amino acid in a solution. .

  The processing apparatus 1 of this Embodiment is an apparatus used in order to perform 1 or more of the some process which comprises such a solid-phase synthesis. For example, the two or more processes performed using the processing apparatus 1 of the present embodiment may be two or more continuous processes or two or more discontinuous processes. The one or more processes performed using the processing apparatus 1 of the present embodiment may be any process among a plurality of processes of solid phase synthesis. The one or more processes performed using the processing apparatus 1 of the present embodiment may be, for example, one or more processes including a process in which microwave irradiation is performed on a liquid in which a solid phase resin is suspended. preferable. For example, the one or more treatments may include a treatment for deprotecting an amino acid protected at the N-terminus bound to the solid phase resin. The one or more treatments may include a treatment of condensing amino acids by performing a dehydration reaction on the deprotected amino acids bound to the solid phase resin. Moreover, it is preferable that one or more processes performed using the processing apparatus 1 of this Embodiment are one or more processes including the process which isolate | separates solid phase resin by filtration. The solid phase resin here is, for example, a solid phase resin in which one or more amino acids are linked. For example, it may be a process of filtering the solid phase resin from a solution in which the solid phase resin after the amino acid is bound is suspended, and the solid phase resin to which the amino acid with the N-terminal protected is bound. After the deprotection treatment, the solid phase resin may be separated from the liquid in which the solid phase resin is suspended by filtration. Moreover, after the solid phase resin is washed with a cleaning liquid (for example, a solvent), the solid phase resin may be filtered. Further, the one or more processes performed in the processing apparatus 1 of the present embodiment may be a combination of two or more of the processes described above. For example, in the one or more processes performed using the processing apparatus 1 of the present embodiment, a deprotection process and a deprotection process are performed on a solid phase resin to which an amino acid whose N-terminal is protected is bound. A process of filtering and washing the solid phase resin, a process of condensing an amino acid whose N-terminal is protected to a deprotected amino acid of the washed solid phase resin, and a process of filtering and washing the solid phase resin And repeating the extension process of one amino acid chain composed of

  The container 101 is a container in which one or more processes of solid phase synthesis are performed. In the container 101, for example, a substance used for solid phase synthesis, an intermediate product, a solvent, and the like are supplied and held. Substances used for solid phase synthesis are, for example, solid phase resins, amino acids, deprotecting agents, activators, racemization inhibitors and the like. The solid phase resin may be, for example, a solid phase resin in which one or more amino acids are linked in advance, or may be a solid phase resin in which a linker molecule and one or more amino acids are linked. A solid phase resin that is not linked may be used. Further, this solid phase resin may be a solid phase resin in which only linker molecules are bound. For example, the container 101 holds these substances and intermediate products together with an appropriate solvent. In addition, for example, a liquid used for washing in solid phase synthesis, a gas used for stirring, or the like may be supplied from the outside into the container 101.

  The container 101 is made of a material having microwave reflectivity. The material having microwave reflectivity is, for example, a conductor. The conductor is, for example, a metal. The container 101 is preferably a material having excellent corrosion resistance. For example, the container 101 is preferably made of stainless steel. The thickness of the outer wall etc. of the container 101 is not ask | required. The inner wall of the container 101 may be coated with a material such as polytetrafluoroethylene (PTFE) or glass having high microwave permeability and excellent corrosion resistance. For example, the container 101 has a double-structured container in which the inner wall is made of a material having high microwave permeability and excellent in corrosion resistance, and the outer wall is made of a microwave reflective material such as stainless steel. It may be.

  The container 101 preferably has a structure that does not leak the microwave to the outside when the inside is irradiated with the microwave. For example, the container 101 preferably has a structure in which the inside of the container 101 can be sealed during irradiation with microwaves.

  The container 101 is a vertical container. A vertical container is a container whose longitudinal direction is a substantially vertical direction. The container 101 has a capsule shape in which the top and bottom are hemispherical, and the portion in between is a cylindrical shape. For this reason, as for the cross-sectional shape cut | disconnected in the perpendicular direction of the container 101, as shown in FIG.1 (b), the edge part of a longitudinal direction has a semicircle shape.

  However, the container 101 may have any shape other than the above. For example, considering that the liquid such as the solvent in the container 101 is discharged from the discharge port 1011 provided in the lower part of the container 101, and the filter 105 for separating the solid phase resin by filtration is easily disposed, the container 101 is considered. The shape of is preferably a vertical type as in the present embodiment, but the shape of the container 101 may be a horizontal type container, that is, a container whose longitudinal direction is substantially horizontal. However, the container 101 may be tilted up to about 30 degrees in the longitudinal direction with respect to the horizontal direction.

  Further, the container 101 may have a cylindrical shape, a polygonal column shape, a conical shape, a combination of these shapes, or the like. The container 101 preferably has a shape obtained by rotating a desired shape (for example, a circle, an ellipse, a rounded square, etc.) with an axis extending in the vertical direction or the horizontal direction as the center of rotation, for example, It does not have to have a rotated shape. The container 101 may have a shape that is plane-symmetric with respect to a plane that is perpendicular to the longitudinal direction, or may not have a shape that is plane-symmetric.

  The size of the container 101 of this embodiment is 1 m in diameter and 2 m in height, but this size is an example, and the container 101 may be larger or smaller than this. The size of is not questioned. Further, the ratio of the height, width and depth of the container 101 is not limited.

  The shape, size, and the like of the container 101 are determined according to, for example, the distribution of the microwaves that are radiated to the container 101. For example, the shape and size of the container 101 are preferably set such that the microwave mode in the container 101 is a multimode. The microwave multimode is, for example, a mode in which a microwave standing wave is not generated in the container 101.

  Although not shown in the figure, the outer periphery of the container 101 may be provided with a hot water jacket, a cold water jacket, a heater, or the like for adjusting the temperature of the container 101.

  A discharge port 1011 is provided at the bottom of the container 101. The discharge port 1011 is an opening for discharging the contents of the container 101. The discharge of the contents here may not be all discharge of the contents. The contents in the container 101 are, for example, a substance used for solid phase synthesis as described above, a solvent, a cleaning liquid (for example, a solvent), and the like. The liquid content is a concept including a solution and a suspension. The content discharged from the discharge port 1011 is, for example, a portion filtered from the content held in the container 101 before discharge by a filter 105 described later, and the solid phase separated from the content by filtration. This is the part excluding the resin. Although an example in which one discharge port 1011 is provided is shown here, a plurality of discharge ports 1011 may be provided. The discharge port 1011 is preferably provided at the lowermost part of the container 101 so that the contents in the container 101 are discharged naturally. The size and shape of the discharge port 1011 are not limited.

  The container 101 is provided with a supply port 1012 for supplying a substance and a solvent used for solid-phase synthesis, a cleaning liquid, a gas, and the like into the container 101. The size of the supply port 1012 does not matter. Here, an example in which the supply port 1012 is provided in the upper part of the container 101 is shown, but the supply port 1012 is provided in a position other than the upper part (for example, the side part or the lower part of the container 101). Also good. However, the supply port 1012 for supplying the solid phase resin is preferably provided above the filter 105 so that at least the solid phase resin can be supplied above the filter 105 described later. The supply port 1012 is preferably capable of being closed by a cap, a stopper, etc. (not shown) except during supply. Here, a case where there is one supply port 1012 has been described as an example, but a plurality of supply ports 1012 may be provided. The supply port 1012 may be connected to a pipe (not shown) for sending contents to be supplied into the container 101 to the supply port 1012. In addition, the supply port 1012 may be provided with one or more nozzles (not shown) that extend toward the inside of the container 101 for supplying contents or the like into the container 101. This nozzle may be removable. Here, a case where the supply port 1012 is closed by an openable / closable lid 1012a is shown.

  Note that although the case where the supply port 1012 is provided has been described in this embodiment, the supply port 1012 is not provided as long as a substance or liquid used for solid-phase synthesis can be supplied into the container 101. May be. For example, the supply port 1012 may be omitted when the top and side surfaces of the container 101 are detachable.

  In addition, the container 101 may be provided with a stirring means (not shown) for stirring the contents. The stirring means may be realized by, for example, a stirring blade, a rotating shaft attached to the rotation center of the stirring blade, and a rotating device such as a motor that rotates the rotating shaft. The number and shape of the stirring blades are not limited. Further, the direction in which the rotating shaft extends may be the vertical direction, the horizontal direction, or a direction other than these. Further, the stirring means may be a means for stirring the contents by bubbles (that is, stirring by bubbling) by ejecting bubbles into the liquid content. The stirring means is connected to, for example, an opening or nozzle that blows out an inert gas such as nitrogen, which is provided at the lower part or the side surface of the contents, and the like, and supplies gas to these. It may be a combination with gas supply means such as a cylinder. Instead of the inert gas, a gas that does not affect the solid-phase synthesis or has little influence may be used.

  The container 101 may be provided with a means (not shown) for measuring the temperature in the container 101 such as a temperature sensor inside or outside. Further, the temperature in the container 101 may be feedback controlled using the value acquired by the means for measuring this temperature. Further, a sensor other than a temperature sensor such as a pressure sensor may be provided in the container 101. Further, the container 101 may be provided with a viewing window (not shown) for looking inside the container 101. The observation window is made of, for example, a material having high microwave reflectivity, has a size such that the microwave in the container 101 does not leak, and is a cylindrical member that is closed with glass or the like. It is feasible. However, the structure of the observation window is not limited. Further, the container 101 may be capable of changing the internal pressure. For example, the container 101 may be one that can be depressurized or pressurized. The container 101 may be connected to a means (not shown) such as a pump for changing the pressure in the container 101, for example.

  The irradiation means 102 has three sets of the microwave oscillator 1021 and the waveguide 1022 and irradiates the container 101 with microwaves from three places. The three waveguides 1022 of the irradiation means 102 are attached to the container 101 so that the opening at each end communicates with the irradiation openings 1013 that are openings provided at three different locations of the container 101. Yes. The irradiation opening 1013 opens so as to allow communication between the inside and the outside of the container 101. For example, the end of each waveguide 1022 connected to the irradiation opening 1013 of the container 101 is the end of each waveguide 1022 opposite to the end connected to the microwave transmitter 1021. . The end of each waveguide 1022 connected to the irradiation opening 1013 of the container 101 is the end from which the irradiation unit 102 emits microwaves, and the position where this end is connected is, for example, the irradiation unit. Reference numeral 102 denotes a position where the microwave is emitted. Here, for example, the ends of the three waveguides 1022 are arranged around the virtual central axis extending in the longitudinal direction of the container 101 so as to be equally spaced from each other at the same height position on the upper part of the container 101. So connected.

  Each microwave transmitter 1021 generates a microwave. The microwaves generated by the respective microwave transmitters 1021 are transmitted through the waveguides 1022 connected to the respective microwave transmitters 1021, and are irradiated from the ends of the respective waveguides 1022 to which the container 101 is connected. The light is emitted into the container 101 through the part 1013. For this reason, the microwave which each microwave transmitter 1021 generate | occur | produces turns into a microwave which the irradiation means 102 radiate | emits. There is no limitation on the frequency, intensity, etc. of the microwaves emitted from each microwave transmitter 1021. The frequency of the microwave emitted from each microwave transmitter 1021 may be, for example, 915 MHz, 2.45 GHz, 5.8 GHz, or other range of 300 MHz to 300 GHz. May be the frequency. The microwave oscillator 1021 is, for example, a magnetron, a klystron, a gyrotron, or a semiconductor oscillator.

  The waveguide 1022 is used as a transmission unit that transmits microwaves. The waveguide 1022 generally has a shape matching the frequency of the microwave generated by the microwave transmitter 1021. Note that the irradiation opening portion 1013 connected to the end portion of the waveguide 1022 may be blocked with a material such as fluorinated polymer such as PTFE having high microwave permeability, glass, rubber, and nylon. For example, it may be closed with a plate made of these materials. The position where the irradiation unit 1022 emits the microwave into the container 101 may be considered as the center of the opening of the end connected to the container 101 of the waveguide 1022, for example. The waveguide 1022 may be attached to the container 101 so that the end on the container 101 side protrudes into the container 101. For example, the end of the waveguide 1022 on the container 101 side may pass through the irradiation opening 1013 and be exposed in the container 101. In addition, the waveguide 1022 may be closed with a material such as fluorinated polymer such as PTFE having high microwave permeability, glass, rubber, and nylon. For example, it may be closed with a plate made of these materials. The position where the waveguide 1022 is closed may be a portion on the container 101 side (for example, an end on the container 101 side) or a portion on the microwave oscillator 1021 side, and the position is not limited.

  Note that the irradiation unit 1022 may be other than the above as long as the microwave can be irradiated into the container 101.

  For example, the irradiation unit 1022 is not limited to the one that irradiates the container 101 with microwaves from three places, and may be any unit that irradiates the microwaves from one or more positions in the container 101. For example, the irradiation unit 1022 has one or more sets of a microwave transmitter 1021 and a waveguide 1022 connected to an irradiation opening 1013 provided in the container 101, and each micro Microwaves generated by the transmitter 1021 may be emitted from the waveguide 1022 into the container 101.

  Further, instead of connecting one waveguide 1022 to one microwave transmitter 1021, a waveguide 1022 having a structure branched into two or more is connected to one microwave oscillator 1021. In this way, the end of the branched waveguide 1022 is connected to different irradiation openings 1013 provided in the container 101, and the microwave generated from one microwave oscillator 1021 is branched into a plurality by the waveguide 1022. Thus, the light may be emitted into the container 101 from a plurality of positions of the container 101.

  Further, if the position where the end of one or more waveguides 1022 is connected to the container 101, that is, the position where the irradiation means 1022 is connected to the container 101 is above the filter 105 described later, the container For example, it may be connected to the side of the container 101 or the like. This connection position is determined according to, for example, the shape of the container 101, the height of the content held in the container 101, the wavelength of the microwave emitted by the irradiation unit 102, and the like.

  The irradiation unit 102 further includes, for example, an end of the waveguide 1022 connected to the container 101 or an antenna (not shown) connected to the irradiation opening 1013 to which this end is connected. May be. This antenna is for emitting microwaves to the container 101, and is installed in the container 101. In this case, this antenna becomes a portion that emits the microwave of the irradiation unit 1022, and the position where the irradiation unit 102 emits the microwave may be considered as the position where the microwave of the antenna is emitted, for example.

  Further, in the irradiation means 102, another transmission unit such as a coaxial cable may be used in place of the waveguide 1022 as a transmission path for transmitting the microwave generated by the microwave transmitter 1021. For example, by inserting the other end of the coaxial cable whose one end is connected to the microwave transmitter 1021 into the irradiation opening 1013 provided in the container 101, microwaves are irradiated into the container 101 through the coaxial cable. Is possible. Further, when the microwave generated by the microwave transmitter 1021 can be irradiated into the container 101 without using a transmission unit such as the waveguide 1022, the transmission unit may be omitted.

  Further, the irradiation means 102 is an antenna (not shown) connected to an end portion (or an irradiation opening portion 1013 connected to this end portion) of the transmission portion such as a coaxial cable connected to the container 101, for example. May further be included. This antenna is for emitting microwaves to the container 101, and is installed in the container 101. In this case, this antenna becomes a portion that emits the microwave of the irradiation unit 1022, and the position where the irradiation unit 102 emits the microwave may be considered as the position where the microwave of the antenna is emitted, for example.

  Further, the irradiation unit 102 may emit microwaves having different frequencies into the container 101. For example, as the plurality of microwave oscillators 1021 included in the irradiation unit 102, a plurality of microwave oscillators 1021 having different frequencies of generated microwaves may be used. The irradiation unit 102 may emit microwaves having different frequencies into the container 101 at the same time, or may switch microwaves having different frequencies and emit them at different timings.

  A valve 103 is attached to the discharge port 1011 of the container 101. The valve 103 is further connected to the pipe 104. The valve 103 is used as a discharge means for controlling discharge of the contents in the container 101 from the discharge port 1011. By opening the valve 103, the contents in the container 101 are discharged from the container 101 through the pipe 104 connected to the valve 103. By closing the valve 103, the contents are held in the container 101. The valve 103 may be a manual valve or an automatic valve such as a solenoid valve. The material of the valve 103 is not limited. When the contents in the container 101 are directly discharged from the valve 103, the pipe 104 may be omitted. Further, as described above, the valve 103 may be directly attached to the discharge port 1011 or may be indirectly attached via a pipe or the like (not shown).

  Further, in the present embodiment, the case where the valve 103 is provided has been described. However, as long as the discharge unit is attached to the discharge port 1011 of the container 101 and can control the discharge of the contents in the container 101, A discharge means other than the valve 103 may be provided. For example, a plug or a lid that can open and close the discharge port 1011 may be provided as the discharge means. For example, an automatic drain plug that can open and close the discharge port 1011 of the container 101 may be attached to the discharge port 1011 as a discharge means. In the present embodiment, the case where the valve 103 is a part of the processing apparatus 1 has been described as an example. However, the discharging means such as the valve 103 may be considered as a part of the processing apparatus 1. It may be considered that it is attached to the outside of the processing apparatus 1 instead of a part of the processing apparatus 1.

  The filter 105 separates the solid phase resin used for the solid phase synthesis from the contents in the container 101. For example, the filter 105 filters the content (eg, liquid, solid having a smaller size than the solid phase resin) having a smaller size (eg, particle size) than the solid phase resin from the contents by filtration. It is for separating solids larger than the phase resin. The filter 105 is made of a microwave transmissive material. The microwave permeable material is, for example, a material having high microwave permeability. A material having a high microwave permeability is, for example, a material having a small relative dielectric loss. Moreover, it is preferable that the microwave transparent material is composed of, for example, a chemically inert material having excellent corrosion resistance. For example, the filter 105 is made of a fluorinated polymer such as PTFE, polypropylene, quartz, glass, nylon, rubber, or the like.

  The filter 105 has a plurality of holes for separating the solid phase resin used for solid phase synthesis from the contents in the container 101. The hole is, for example, a hole that communicates from the upper surface 1051 to the back surface. The filter 105 is made of, for example, a porous material. However, the filter 105 may be a mesh or the like. The content in the container 101 is, for example, a liquid (for example, a suspension) containing a solid phase resin used for solid phase synthesis as described above. This liquid is, for example, a liquid in which an activator or amino acid as described above used for solid phase synthesis is dissolved or suspended. The liquid containing the solid phase resin may be a liquid suspension such as a solvent for washing the solid phase resin and the solid phase resin. The plurality of holes included in the filter 105 are, for example, holes having a size that does not allow the solid phase resin contained in the contents to pass therethrough, and are holes having a size that allows the contents other than the solid phase resin of the contents to pass therethrough. Other than the solid phase resin of the contents, for example, a solvent, a substance such as an activator or a deprotecting agent used in solid phase synthesis in a solvent state, or an amino acid dissolved or suspended in a solvent Etc. The plurality of holes included in the filter 105 are, for example, holes that are smaller in size than the solid phase resin included in the contents and larger in size than those other than the solid phase resin of the contents. For example, the plurality of holes included in the filter 105 are holes whose size is smaller than the particle size of the solid phase resin contained in the contents. As a result, only the solid phase resin of the contents in the container 101 is separated by filtration and remains on the upper surface 1051 of the filter 105, and the activator or deprotecting agent dissolved in the solvent or the solvent. The dissolved or suspended amino acids and the like pass through the holes of the filter 105 together with the solvent. For example, when a granular solid phase resin having a diameter of 50 μm to 150 μm is used as the solid phase resin, the pore diameter of the filter 105 is preferably smaller than these, for example, less than 50 μm.

  The solid phase resin filtered and separated by the filter 105 may be a solid phase resin alone, or a solid phase resin in which a linker molecule, one or more amino acids, a peptide, or the like is bound. Also good. For example, the above-described filter 105 may be considered to have a plurality of holes for separating the solid phase resin in which amino acids and peptides are bound from the contents in the container 101. The solid phase resin separated from the contents by the filter 105 is a resin-containing solid that is a solid containing the solid phase resin, regardless of whether or not a linker molecule, one or more amino acids, a peptide, or the like is bound. You may call it. For example, the filter 105 may be considered as separating the resin-containing solid from the contents in the container 101. This also applies to the description of the reflecting member 106 described later.

  The filter 105 is disposed so as to partition the container 101 between the discharge port 1011 and the position where the irradiation unit 102 emits microwaves. In the present embodiment, the filter 105 is arranged so as to partition the container 101 into two upper and lower regions at a position between the discharge port 1011 and the position where the irradiation means 102 emits microwaves. To partition the container 101 by the filter 105 is to provide the filter 105 so that the contents in the container 101 do not move between the two regions partitioned by the filter 105 without passing through the filter. In the present embodiment, an example is shown in which the filter 105 is provided so that no gap is generated between the outer peripheral portion of the filter 105 and the side surface of the container 101. The filter 105 is disposed so as to partition the container 101 between the discharge port 1011 and the position where the irradiation unit 102 emits the microwave. For example, the filter 105 includes the discharge port 1011 and the irradiation unit. 102 is disposed between the position where the microwave is emitted, and the contents of the container 101 are on the irradiation unit 102 side with respect to the filter 105 and on the discharge port 1011 side with respect to the filter 105. The filter 105 is arranged so as not to move between the regions without passing through the filter 105.

  In the present embodiment, as an example, a case where a sheet-like filter 105 made of a porous material made of PTFE is used will be described. The filter 105 is disposed in the container 101 so that the upper surface 1051 is substantially flat and the upper surface 1051 is horizontal. In the present embodiment, the container 105 is vertically partitioned by the filter 105 by arranging the filter 105 in this way. However, the upper surface 1051 of the filter 105 may not be substantially flat, and for example, unevenness may be provided. The filter 105 may be arranged such that the upper surface 1051 is inclined with respect to the horizontal.

  Although the case where the filter 105 has a sheet shape is described here, the filter 105 may be a filter having a shape other than a sheet shape such as a flat plate shape. Further, the thickness and strength of the filter 105 are not limited. The filter 105 preferably has a substantially uniform thickness, but may have a non-uniform thickness.

  The reflection member 106 is disposed so as to partition the container 101 between the filter 105 in the container 101 and the discharge port 1011. The reflection member 106 is disposed at a position away from the discharge port 1011 in the height direction. On the reflecting member 106, the filter 105 is disposed so as to overlap. Arranging on the reflecting member 106 means, for example, arranging on the upper surface 1061 of the reflecting member 106. Here, the reflecting member 106 is a flat plate member, the upper surface 1061 thereof is substantially flat, and is disposed in the container 101 so that the upper surface 1061 is horizontal, and the filter 105 is superimposed on the upper surface 1061. Has been placed. Note that the upper surface 1061 of the reflecting member 106 may not be substantially flat. Further, the upper surface 1061 of the reflecting member 106 may not be disposed horizontally. Further, the reflecting member 106 may not be a flat plate member. It is preferable that the upper surface 1061 of the reflecting member 106 has a shape on which the sheet-like or flat filter 105 can be stably placed.

  The material of the reflecting member 106 is stainless steel, which is a material having microwave reflectivity. The reflecting member 106 has a plurality of holes 106 a having a circular shape in a planar shape that is sized to allow at least the contents in the container 101 that passes through the filter 105 to pass therethrough. The hole 106a is, for example, a hole that communicates from the upper surface 1061 to the back surface 1062. The diameter of each hole 106 a is set to a size that allows at least the contents in the container 101 that passes through the filter 105 to pass through and reflects the microwaves emitted by the irradiation unit 102. The size that allows at least the contents in the container 101 that passes through the filter 105 to pass is, for example, the size of the contents in the container 101 that are larger than the size that allows the contents that pass through the filter 105 to pass through. For example, the size of the contents in the container 101 excluding the solid phase resin separated by the filter 105 may be passed, or the size including the solid phase resin may be passed. There may be. The irradiation means 102 emits the diameter of the hole provided in the plate made of the material having microwave reflectivity and the width of the widest portion of the opening of the mesh made of the material having microwave reflectivity. If the microwave is smaller than the half wavelength of the microwave, the microwave is reflected by this plate or mesh. Therefore, the diameter of the plurality of holes 106 a provided in the reflecting member 106 is, for example, the microwave emitted by the irradiation unit 102. The size may be smaller than the half-wavelength and larger than the size through which the content passing through the filter 105 can pass. Note that the size of the hole 106a of the reflecting member 106 is, for example, a size that is smaller than the half wavelength of the microwave emitted by the irradiation unit 102 and that does not hinder the passage of the content that has passed through the filter 105. preferable. The number and the arrangement pattern of the plurality of holes 106a are not limited. In the present embodiment, as an example of the reflecting member 106, a stainless punching metal having a plurality of holes 106a is used. In ordinary solid phase synthesis, the solid phase resin has the largest size among the contents in the container 101. Therefore, as long as the solid phase resin can pass through the reflecting member 106, the contents other than the solid phase resin are also included. It can pass through the reflecting member 106. 2 (b), 2 (d), etc. are diagrams for explanation, and the size of the plurality of holes provided in the reflecting member 106 in these drawings and the size of the reflecting member 106 are as follows. The relationship, the arrangement of the holes 106a, the number of the holes 106a, and the like are for explanation, and are not necessarily the same as those of the actual reflecting member 106.

  As described above, the reflecting member 106 is made of stainless steel, and is provided with a plurality of holes of a size that reflects the microwaves emitted from the irradiation unit 102. Therefore, the reflecting member 106 emits from the irradiation unit 102. It is designed to reflect microwaves. Here, the reflection of the microwaves by the reflection member 106 may be all reflections of the microwave irradiated to the reflection member 106, but may not be all reflections. For example, a part of the irradiated microwave may pass through the reflecting member 106 and the rest may be reflected, or a part of the irradiated microwave may be absorbed by the reflecting member 106.

  The reflection member 106 may be made of any material and may have any shape and size as long as it reflects the microwave emitted by the irradiation unit 102. . For example, the reflecting member 106 may be made of a microwave reflective material other than stainless steel (for example, a metal other than stainless steel). However, the material of the reflecting member 106 is preferably a material that has excellent corrosion resistance and is chemically stable. In addition, while using a metal as a material of the reflecting member 106 and coating the surface with a material having microwave permeability such as PTFE having corrosion resistance, the corrosion resistance is not impaired. May be improved. Further, the planar shape of the plurality of holes provided in the reflecting member 106 may be a shape other than the round shape described above (for example, a polygonal shape) as long as it has a size capable of reflecting microwaves. . For example, the reflecting member 106 is made of a material having microwave reflectivity, and is a member having a plate shape having a plurality of holes that do not transmit microwaves emitted from the irradiation unit 102. Also good.

  The reflecting member 106 is a flat plate having a plurality of holes as described above, as long as it can pass at least the contents in the container 101 that has passed through the filter 105 and has a shape that can reflect microwaves. It does not have to be a shaped member, and may have any shape and size. For example, the reflecting member 106 may be a mesh having a plurality of openings each having a size that does not allow microwaves to pass therethrough. The reflecting member 106 may be other than the above as long as it can pass at least the contents that have passed through the filter 105 and can reflect microwaves. For example, the reflecting member 106 passes through a solid phase resin. A porous metal filter having possible pores may be used. Note that when the filter 105 is reinforced and supported by the reflecting member 106 from below, the material of the reflecting member 106 is preferably a material having high strength such as metal.

  The filter 105 is preferably disposed at a position that is not higher than ¼ of the height of the container 101 in order to sufficiently secure a region where solid phase growth processing is performed, but is higher than ¼. The filter 105 may be disposed at the height position.

  The reflection member 106 is disposed so as to partition the container 101 up and down. The fact that the reflecting member 106 is arranged so as to partition the container 101 means that, for example, the microwave emitted into the container 101 from above the reflecting member 106 is reflected so as not to pass below the reflecting member 106. The member 106 is disposed in the container. Further, partitioning the container 101 up and down may be considered as partitioning the inside of the container 101 into upper and lower regions, for example. For example, in the present embodiment, the reflecting member 106 partitions the container 101 in the vertical direction by disposing the reflecting member 106 in the container 101 so that the upper surface 1061 of the reflecting member 106 is horizontal. By the member 106, the inside of the container 101 is partitioned into an upper region 101a and a lower region 101b.

  In the processing apparatus 1 of the present embodiment, the microwave can be confined in the container 101 by irradiating the microwave from the irradiation means 102 into the container 101 made of a microwave reflective material. The contents can be efficiently irradiated with microwaves. In addition, the microwave in the container 101 can be set to a multi-mode, and compared to the single mode, the microwave can be prevented from being concentrated in one place. The microwave can be irradiated evenly. For this reason, even if the container 101 is enlarged, the contents can be efficiently and evenly irradiated with microwaves. Thereby, in this Embodiment, it becomes possible to enlarge the container 101 and to increase the processing amount of the peptide etc. by solid phase synthesis.

  Moreover, the processing apparatus 1 of this Embodiment can isolate | separate solid-phase resin from the content, and can leave in the container 101 by providing the filter 105. FIG. As a result, a solvent for cleaning is supplied into the container 101 from which the solid phase resin has been separated to wash the solid phase resin, or other materials, solvents, solutions, etc. are placed into the container 101 from which the solid phase resin has been separated. It is possible to perform other processes constituting the solid phase synthesis without once supplying and taking out the solid phase resin.

  Here, in a large container capable of processing a large amount of contents, the size of the discharge port is often smaller than the size of the entire container. For this reason, like the processing apparatus 1 of this embodiment, the lower part of the container 101 may have a shape that becomes thinner as it goes from above to the discharge port 1011 so that the contents can be easily discharged during discharge. Many. In such a case, when the filter 105 for separating the solid phase resin as described above is arranged at a location close to the discharge port 1011 so as to partition the container 101 vertically, the filter 105 is located away from the discharge port 1011. The area of the upper surface of the filter 105 becomes smaller compared to the case where the filter 105 is disposed in the area. When the area of the upper surface 1051 of the filter 105 is reduced in this way, when the contents are discharged, the speed at which the contents are filtered is reduced, and the pores of the filter 105 are filtered by the solid phase resin that is filtered and remains on the filter 105. It is conceivable that the clogging is likely to be blocked, and the filtration speed is further slowed or the filtration is stopped. For this reason, as in the present embodiment, the filter 105 is arranged on the upper surface of the filter 105 so as to partition the container 101 vertically at a position away from the discharge port 1011 in the height direction as described above. It is preferable for increasing the area.

  In such a processing apparatus 1, when contents including a solid phase resin and a solvent used for solid phase synthesis are supplied to the region 101 a above the filter 105, the content below the filter 105 in the container 101 is lower. Since the region 101 b is provided with the filter 105, the content held in the region 101 a above the filter 105 excluding the solid phase resin is supplied through the filter 105. Note that the region here may be considered as a space.

  However, as in the processing apparatus 1 of the present embodiment, in the processing apparatus in which the filter 105 that does not allow the solid phase resin to pass therethrough has microwave permeability and the container 101 is made of a reflective material, When the member 106 is not provided, the microwave irradiated from above the filter passes through the filter 105 having microwave permeability to accelerate the solid-phase synthesis process, and the region 101 b below the filter 105. The contents will be irradiated. Since the content of the region 101b below the filter 105 does not include a solid phase resin used for amino acid binding, even if the content of the region 101b below the filter 105 is irradiated with microwaves, the solid phase resin is used. The synthesis process is not performed, and the microwave does not directly contribute to the solid-phase synthesis, and wastes energy. In particular, when the size of the container 101 is increased in order to increase the throughput of solid-phase synthesis, it is considered that the region 101b below the filter 105 is also increased in size, so that microwaves cannot be used efficiently. It is done.

  On the other hand, in the processing apparatus 1 according to the present embodiment, the reflection member 106 that reflects the microwave is provided below the filter 105, so that the microwave irradiated from above the filter 105 is microwaved. Although it passes through the filter 105 having transparency, it is reflected by the reflecting member 106 below it and returned to the region 101a above the filter 105 holding the content containing the solid phase resin. The microwave can be made difficult to irradiate the region below the filter 105 where the solid phase synthesis is not performed, and the microwave reflected by the reflecting member 106 can also be used for the solid phase synthesis. It can be used for solid phase synthesis. In particular, when the container 101 is enlarged in order to increase the throughput of solid phase synthesis, the region 101b below the filter 105 is considered to be enlarged, so in the processing apparatus 1 of the present embodiment, it is wasteful. It is possible to efficiently perform solid phase synthesis while suppressing excessive energy consumption. Further, since the reflecting member 106 has a shape and a size through which the contents that have passed through the filter 105 can pass, the reflecting member 106 does not hinder discharge of the contents.

  Further, in the processing apparatus 1 of the present embodiment, the filter 105 is placed on the reflecting member 106 made of a reflective material such as metal, and thus is placed on the upper surface 1061 by the reflecting member 106. The filter 105 can be reinforced and supported. For this reason, for example, a filter 105 made of a low-hardness material that is difficult to arrange so as to partition the container 101 alone, a sheet-like filter 105, or the like may be arranged so as to partition the inside of the container 101. it can. Thereby, the selection range of the filter 105 can be expanded.

  Hereinafter, an example of a solid phase synthesis process using the processing apparatus 1 of the present embodiment will be described. Here, a process for deprotecting a solid phase resin to which an amino group protected at the N-terminus is bonded and further bonding the amino group by a dehydration reaction will be described. However, the substances used in the solid phase synthesis, the blending thereof, etc. are merely examples, and it goes without saying that other substances may be used. Moreover, the procedure of the process performed here is an example, and you may process by a procedure other than this. Needless to say, in the vessel 101, solid-phase synthesis processing other than the processing described here may be performed, or only part of the processing described here may be performed. Absent.

  First, in a state in which the valve 103 is closed so that the contents are not discharged from the discharge port 1011, deprotection of a pepyridine solution or the like using DMF or the like as a solvent is performed via a supply port 1012 provided above the filter 105. A solution and a solid phase resin to which an amino group whose N-terminal is protected with fmoc or the like are bonded are supplied into the container 101. Then, nitrogen gas is supplied to the contents in the container 101 via a nozzle or the like (not shown) and a microwave of 915 MHz is irradiated from the irradiation means 102 while stirring with bubbles to perform a deprotection process. Since the container 101 is provided with the filter 105, the deprotection solution and the solid phase resin are held above the filter 105, and only the deprotection solution is held below the filter 105. However, the deprotection solution moves through the filter 105 and the reflection member 106. The microwave emitted from the irradiation unit 102 is reflected by the reflecting member 106 to the region 101a above the filter 105, and the region 101b below the filter 105 where no solid phase resin is present, that is, the region that does not require deprotection processing. Microwaves can be made difficult to irradiate.

  When the valve 103 is opened after the deprotection processing is completed, the deprotection solution below the filter 105 of the contents in the container 101 is discharged to the outside through the discharge port 1011, the valve 103, and the pipe 104. The deprotection solution below the filter 105 passes through the filter 105 and the reflection member 106, and is then discharged to the outside through the discharge port 1011, the valve 103, and the pipe 104. Of the contents in the container 101, the deprotected solid phase resin is separated from the deprotected solution and remains on the upper surface 1051 of the filter 105.

  Next, after supplying and holding DMF in the container 101, the DMF is discharged and the deprotected solid phase resin remaining on the upper surface 1051 of the filter 105 is washed. This cleaning process is performed a plurality of times.

  The HCTU (O- (6-chlorobenzotriazol-1-yl) -N, N, N ′, N′-tetramethyluronium hexafluoro is then used to bind amino acids to the deprotected solid phase resin. Phosphate), DIPEA, amino acid for binding whose N-terminal is protected with Fmoc, and DMF used as a solvent are supplied into the container 101, and HCTU, DIPEA, and the amino acid for binding are dissolved in DMF and irradiated. By irradiating the microwave from the means 102, the amino acid whose N-terminal is protected and the deprotected amino acid bound to the solid phase resin are bound by dehydration reaction. Similarly to the above, the container 101 is provided with the filter 105. Therefore, in the region 101a above the filter 105, a binding solution in which HCTU, DIPEA, and a binding amino acid are dissolved in DMF; The deprotected solid phase resin is held, and only the binding solution is held in the region 101 b below the filter 105. However, the binding solution moves through the filter 105 and the reflecting member 106. The microwave emitted from the irradiation unit 102 is reflected by the reflecting member 106 to the region 101a above the irradiation unit 102, and the region 101b below the irradiation unit 102 where no solid phase resin is present, that is, processing for binding amino acids is unnecessary. This region can be made difficult to be irradiated with microwaves.

  When the valve 103 is opened after the binding of amino acids is completed, the binding solution is discharged from the container 101, and a solid phase resin in which an amino acid whose N-terminal is protected is newly bound to the upper surface 1051 of the filter 105. It remains without being discharged.

  Thereafter, the washing process using DMF is repeated a plurality of times as described above.

  Thereby, the peptide couple | bonded with the solid-phase resin can be obtained on the upper surface 1051 of the filter 105.

  Further, when a new amino acid is bound to the peptide, the above-described deprotection treatment and a series of treatments for binding the amino acid may be repeated.

When separating the solid phase resin from the peptide bound to the solid phase resin remaining on the upper surface 1051 of the filter 105, for example, the solid phase resin remaining on the upper surface 1051 of the filter 105 with trifluoroacetic acid (TFA) and H ₂ O. Can be processed. The cleaved peptide is collected, for example, by precipitation with ethyl ether and drying.

  As described above, according to the present embodiment, by irradiating microwaves into the container 101 having microwave reflectivity, the container 101 is enlarged and the throughput of peptides and the like by solid phase synthesis is increased. It becomes possible to make it.

  In addition, according to the present embodiment, the filter 105 is placed on the reflection member 106 so that the reflection member 106 reflects the microwave transmitted through the filter 105, and the solid phase resin below the filter 105. It is possible to make it difficult to irradiate the contents not containing the microwave with the microwave, and the microwave can be efficiently used for the solid-phase synthesis process.

  Further, according to the present embodiment, the filter 105 can be reinforced by the reflecting member 106 by arranging the filter 105 on the reflecting member 106, and thus, for example, the filter 105 is required. Restrictions such as strength and hardness can be relaxed, and the selection range of the filter 105 can be widened.

(Modification)
FIG. 3A to FIG. 3C are cross-sectional views for explaining a modification of the processing apparatus according to the present embodiment, and are cross-sectional views corresponding to FIG.

  In the above-described embodiment, the case where the filter 105 is disposed on the reflecting member 106 has been described. However, if the reflecting member 106 is disposed between the filter 105 and the discharge port 1011, the filter 105 is disposed on the reflecting member 106. It does not have to be placed directly on top. For example, as shown in FIG. 3A, the filter 105 and the reflecting member 106 may be arranged so as not to directly overlap each other. Even in such a case, the microwave transmitted through the filter 105 is reflected by the reflecting member 106 disposed below the filter 105, and the microwave is irradiated to the region 101b below the reflecting member 106. Therefore, microwaves can be efficiently used for solid phase synthesis. However, in this case, microwaves are applied to the content between the filter 105 and the reflecting member 106 that does not include the solid phase resin, and thus the filter 105 is overlaid on the reflecting member 106. Compared to the above, it is conceivable that microwaves cannot be used efficiently. In this case, since the filter 105 cannot be reinforced by the reflecting member 106, the filter 105 having sufficient strength without being reinforced is used as the filter 105, or the filter 105 has microwave permeability separately. It is necessary to attach a material reinforcing member (for example, a reinforcing frame), and the material and structure that can be used as the filter 105 are limited. Can be expected to rise.

  Further, instead of disposing the reflection member 106 between the filter 105 and the discharge port 1011, as shown in FIG. 3B, the reflection member 106 is disposed between the filter 105 and the irradiation unit 102. Even in such a case, by reflecting the microwave with the reflecting member 106, it is difficult to irradiate the region 101b below the filter 105 with the microwave, and the microwave can be used efficiently. It becomes possible. However, in this case, it is assumed that the reflecting member 101 can pass through the solid phase resin so that the solid phase resin exists in the region 101 a above the filter 105. For example, as the reflecting member 101, a member having a shape and size capable of passing through a solid phase resin is used. Note that in this case, microwaves are not easily irradiated to the contents including the solid phase resin between the reflecting member 106 and the filter 105, and thus the distance between the reflecting member 106 and the filter 105 is increased. There is a possibility that the efficiency of the solid phase synthesis process is lowered.

  Further, as one mode in which the reflecting member 106 is disposed between the filter 105 and the irradiation unit 102, the reflecting member 106 is disposed so as to overlap the upper surface 1051 side of the filter 105 as illustrated in FIG. You may do it. In this case, the distance between the reflecting member 106 and the filter 105 can be eliminated to prevent a reduction in the efficiency of the solid-phase synthesis process as described above, and the filter 105 can be attached to the lower surface of the reflecting member 106. The filter 105 can be reinforced with the reflecting member 106 by fixing with an adhesive or the like, or by fixing with a fastener (not shown) or a screw.

(Embodiment 2)
The processing apparatus according to the present embodiment uses a filter that reflects microwaves instead of using the filter 105 and the reflecting member 106 in the processing apparatus 1 described in the first embodiment.

  FIG. 4 is a perspective view (FIG. 4A) showing an example of a processing apparatus in the present embodiment, and a sectional view taken along line IVb-IVb (FIG. 4B). However, the cross section of the valve is omitted in FIG.

  The processing apparatus 2 according to the present embodiment includes a container 101, an irradiation unit 102, a valve 103, a pipe 104, and a filter 205. The container 101 includes a discharge port 1011, a supply port 1012, and an irradiation opening 1013. Since the configuration other than the filter 205 is the same as that of the first embodiment, detailed description thereof is omitted here.

  The filter 205 is a filter made of stainless steel, which is a microwave reflective material, and has a plurality of holes for separating the solid phase resin from the contents in the container 101. The filter 205 may have any material, shape, or the like as long as it reflects microwaves. The filter 205 may be made of, for example, a microwave reflective material such as a metal other than stainless steel. However, the filter 205 is preferably made of a chemically stable material having excellent corrosion resistance. For example, the filter 205 may be a metal filter whose surface is coated with a material having microwave permeability such as PTFE having corrosion resistance. The size and the like of the plurality of holes for separating the solid phase resin that the filter 205 has from the contents in the container 101 are the same as the holes that the filter 105 of the above-described embodiment has. Omitted. As a metal filter such as stainless steel, for example, a metal filter or the like in which a plurality of metal meshes are stacked and integrated by sintering is known.

  The filter 205 is arranged so as to partition the container 101 between the discharge port 1011 and the position where the irradiation unit 102 emits the microwave, as in the filter 105 of the above embodiment.

  When the filter 205 is a filter made of metal such as stainless steel, it is possible to arrange the filter alone in the container 101 depending on the thickness. However, due to lack of hardness and strength, the filter When it is difficult to arrange 205 in the container 101 alone, a reinforcing frame or the like may be attached to the filter 205.

  In this embodiment as well, as in the above embodiment, the container 101 can be enlarged to increase the throughput of peptides and the like by solid-phase synthesis, and in the region 101b below the filter 205. Since the solid phase resin is not included, the microwave irradiated from the irradiation unit 102 is reflected by the filter 205 to the region 101a above the filter 205, so that the solid phase resin below the filter 205 is included. It is possible to make it difficult to irradiate the contents that are not exposed to microwaves, and the microwaves can be efficiently used for solid-phase synthesis.

  In each of the above embodiments, the case where the processing apparatuses 1 and 2 are used for solid phase synthesis for synthesizing a peptide bonded to a solid phase resin has been described. However, the processing performed using the processing apparatuses 1 and 2 is as follows. However, it is not limited to the process of solid phase synthesis of peptides.

  For example, in each of the embodiments described above, the filter 105 or the filter 205 that separates the solid phase resin that is a solid substance is used to separate the solid phase resin that is the content to be separated by the filter 105 or the filter 205. However, in the processing apparatuses 1 and 2 described in each of the above embodiments, the filter 105 and the filter 205 are each a filter having a plurality of holes for separating the solid matter to be separated, The processing apparatuses 1 and 2 may be used for processing including a step of separating the solid matter to be separated from the contents in the container 101. Note that the filter 105 and the filter 205 in this case are the same as the filters 105 and 205 in the above-described embodiments except that the filter 105 and the filter 205 have a plurality of holes for separating the solid matter to be separated. For example, the materials and the like of the filter 105 and the filter 205 in this case are the same as those of the filters 105 and 205 in the above embodiments. The contents here are, for example, contents having a liquid. This liquid may be, for example, a raw material or the like, may be a solvent, etc., and its components are not limited. This liquid may be, for example, a solution in which a substance is dissolved in a solvent or the like. Here, the solid material is, for example, in a solid state. In addition, you may think that a solid substance does not have fluidity | liquidity and can be isolate | separated with a filter etc. For example, a gel-like material may be considered as a solid material. It is preferable that the solid matter to be separated has a shape and size that have fluidity in the liquid of the contents, for example. The solid matter to be separated may be the solid matter of the aspect, for example, a granular, small piece, or powdery solid. The filters 105 and 205 having a plurality of holes for separating the solid matter to be separated allow the liquid and the solid matter having a size smaller than that of the solid matter to be separated to pass through, for example. It is a filter which does not let the solid of the above size pass. For example, the filters 105 and 205 having a plurality of holes for separating the solid matter to be separated are pores smaller than the size of the solid matter to be separated, and are smaller than the liquid and the solid matter to be separated. It is a filter having a plurality of pores of a size that can pass through a small size solid material. The contents in the container 101 include, for example, a liquid and a solid material to be separated. The content may be, for example, a solid suspension to be separated. The content passing through the filters 105 and 205 is, for example, a portion excluding the solid matter to be separated in the content. The content that passes through the filters 105 and 205 is, for example, a liquid in the content. Note that the contents in the container 101 may include, for example, solids other than the separation target that are smaller in size than the separation target solids. In this case, the contents passing through the filters 105 and 205 are, for example, liquids in the contents and solids other than the separation target that are smaller in size than the solids to be separated.

  As described above, the processing apparatuses 1 and 2 in which the filter 105 and the filter 205 are filters having a plurality of holes for separating a solid object to be separated include, for example, a process of irradiating the container 101 with microwaves. And an apparatus that can be used for processing including a step of separating a solid matter to be separated from a content having a liquid in the container 101. Solid phase synthesis of peptides may also be considered an example of such treatment.

  In the modification of the first embodiment, when the reflecting member 106 is disposed between the filter 105 and the position where the irradiation unit 102 emits microwaves, the reflecting member 106 can pass through the solid phase resin. Although the reflecting member 106 is used, when the filter 105 and the filter 205 are filters having a plurality of holes for separating the solid matter to be separated, the filter 105 and the irradiation unit 102 emit microwaves. The reflection member 106 arranged between the positions may be a reflection member that can pass the solid matter to be separated by the filter 105. The reflecting member 106 in this case may be the same as the reflecting member 106 of the modified example of the first embodiment except that the reflecting member 106 can pass through the solid matter to be separated by the filter 105.

  The solid matter to be separated using the filters 105 and 205 may be, for example, a solid matter that has been included in the contents before the microwave irradiation process or the like. The solid substance produced | generated by performing the process etc. which irradiate a microwave may be sufficient.

  The solid matter to be separated contained in the contents before performing the treatment with microwave irradiation is, for example, the fluidity used for adjusting the solid catalyst of the fluidized bed and the microwave absorption. Is a solid material used for processing of a susceptor having a size or the like, an adsorbent that adsorbs another substance, or a solid phase alone. Examples of the fluidized bed solid catalyst include a palladium carbon (Pd / C) catalyst, a platinum carbon (Pt / C) catalyst, a solid acid catalyst, a zeolite catalyst, and the like. Further, the solid matter to be separated, which has been contained in the contents before performing the process of irradiating microwaves, may be solid impurities or the like.

  The solid matter to be separated generated by performing the process of irradiating the microwave is, for example, the solid matter generated by a chemical reaction or the like from the liquid in the contents in the container 101 irradiated with the microwave. It may be a solid substance generated by solidifying a liquid in the contents or crystal growth in the container 101 irradiated with microwaves.

  Further, the solid matter generated by performing the process of irradiating the microwave is included in the contents before the process of irradiating the microwave in the container 101 irradiated with the microwave, for example. It may be a solid produced by chemically reacting the solid with another substance, etc., and is included in the contents before performing the microwave irradiation treatment in the container 101 irradiated with the microwave. It may be a solid that is decomposed by chemically reacting the solid that has been contained, and the surface of the solid contained in the contents is irradiated with microwaves before performing the process of irradiating microwaves. Then, the same substance or different substances may be solids generated by adsorption, adhesion, and growth. Note that the other substances and the same substances described here may be solid, liquid, or gas. In addition, it is preferable that the solid matter contained in the contents before performing the process of irradiating microwaves is placed at least above the filters 105 and 205 in the container 101.

  The solid object to be separated may be a target object for processing such as a solid object to be processed using the processing apparatuses 1 and 2, or a solid material generated by the processing, and may be a catalyst, a susceptor or the like. It may be a solid material used in the above, an unnecessary material, or a mixture of two or more of these. There is no limitation on the size of the solid matter to be separated. The solid matter to be separated may be, for example, a precipitate. The solid matter to be separated may be suspended matter or sediment in the contents. The solid matter to be separated when the processing performed in the processing apparatuses 1 and 2 is solid phase synthesis of a peptide is, for example, a solid phase resin.

  The contents in the container 101 may or may not contain a solid matter to be separated in advance before performing the process of irradiating microwaves.

  As described above, the processing performed using the processing devices 1 and 2 in which the filter 105 and the filter 205 are filters having a plurality of holes for separating the solid matter to be separated is performed, for example, from the contents. What is necessary is just the process which contains 1 or more of the process of isolate | separating the solid substance used as. For example, in the processing performed using such processing apparatuses 1 and 2, the contents containing liquid are irradiated with microwaves, and the solid matter to be separated is separated from the contents using the filter 105 or 205. After the process, a step of adding a liquid or the like as the contents in the container 101, a step of irradiating the container 101 with microwaves, and a solid object to be separated from the contents using the filter 105 or 205 are performed. At least one of the step and set of separating, the step of adding a liquid or the like as the content in the container 101, and the step of separating the solid matter to be separated from the content using the filter 105 or 205 is 1 The process performed above may be used.

Below, a zeolite polycrystal film of crystalline aluminosilicate can be produced by performing the reaction under high-temperature and high-pressure hydrothermal conditions by microwave irradiation. After the treatment is completed, the produced substance can be separated from the content by separating the zeolite polycrystal membrane which is a solid substance with the filter 105 or 205.

The free fatty acid esterification reaction is simultaneously carried out in one container to produce a methyl ester. The solid catalyst used here is, for example, a hybrid solid catalyst in which a substance having a large dielectric loss coefficient and magnetic loss coefficient suitable for irradiation microwaves and a substance having a reactive site are incorporated. In this process, a substance to be processed is placed in the container 101, and the solid catalyst is placed above the filter 105 or 205, irradiated with microwaves, and after the production of the product is completed, By separating the solid catalyst, which is a solid substance, with the filter 105 or 205, the solid catalyst can be removed from the content containing the produced substance.

After the process is completed, the filter 105 or 205 is used as a solid substance. By separating a certain microwave susceptor, the microwave susceptor can be removed from the content containing the generated substance. In this case, as the filter 105 or the filter 205, a filter having a plurality of holes for separating a microwave susceptor that is a solid matter to be separated is used.
