Definitions
- the present invention relates to an irinotecan or irinotecan hydrochloride liposome, a preparation method thereof, and an injection containing the liposome and a preparation method thereof.
- Irinotecan is a semisynthetic derivative of camptothecin. Camptothecin specifically binds to topoisomerase I, which induces reversible single-strand breaks, thereby unwinding the DNA double-stranded structure; irinotecan and its active metabolite SN-38 and topoisomerase The I-DNA complex binds, thereby preventing re-ligation of the cleavage single strand.
- Existing studies suggest that the cytotoxic effect of irinotecan is attributed to the interaction between the replicase and the topoisomerase I-DNA-irinotecan (or SN-38) triple complex during DNA synthesis, resulting in DNA double Chain breakage.

- the particle size of the liposome was 89.4 nm and the entrapment efficiency was 97.2%.
- a prescribed amount of hydrogenated soybean lecithin, cholesterol, and ⁇ -tocopherol were dissolved in an appropriate amount of absolute ethanol to obtain a lipid solution, and mixed with 100 ml of an ammonium sulfate solution, and ethanol was removed under reduced pressure to obtain a crude liposome. Then, using a high-pressure homogenizer 1000bar, homogenizing 5 times, and then extruding the liposome through an extrusion device (extruding 5 sheets of 100 nm extruded film, extruding 5 times), and then adding the prepared DSPE-PEG 5QQQ The aqueous solution was incubated for 20 minutes with stirring.
- the blank liposome was dialyzed by a tangential flow ultrafiltration device, and 400 ml of a 0.9% sodium chloride solution was continuously supplied in the middle to obtain a blank liposome.
- the irinotecan hydrochloride solution was prepared by using water for injection, added to a blank liposome dispersion having an ion gradient, heated and stirred at 60 ° C, and incubated for 20 minutes to obtain a drug-loaded liposome.
- the unencapsulated drug was removed using a tangential flow ultrafiltration device while the sample was concentrated to about 50 ml, and sucrose and mannitol were added to make the mixture uniform.
- Adjust the concentration of the drug adjust the volume, 0.22 ⁇ filter membrane filter sterilization, canned in a vial, freeze-dried, that is, irinotecan hydrochloride liposome freeze-dried powder needle.
- the liposome lyophilized powder was hydrated, and the liposome particle size was determined to be 90.8 nm, and the encapsulation efficiency was 97.5%.
- Test example 1
- Encapsulation rate determination method Pipette 1mL sample solution into 10mL volumetric flask, dilute to the mark with water, shake well, set 8010 ultrafilter (MILLIPORE company) ultrafiltration, discard the primary filtrate, take the filtrate as the test sample Solution.
- Encapsulation rate w ° W x lOO%
- the irinotecan hydrochloride liposome (CPT-11 liposome) prepared according to Example 2 was provided by Shanghai Hengrui Pharmaceutical Co., Ltd., irinotecan hydrochloride injection (CPT-11, Jiangsu Hengrui Pharmaceutical Co., Ltd. Provided by the company)
- Preparation method All the physiological saline is used to prepare the desired concentration.
- mice BALB/cA-nude nude mice, 6-7 weeks, $, purchased from Shanghai Slack Laboratory Animals LLC. Certificate No.: SCXK (Shanghai) 2007-0005. Breeding environment: SPF level.
- Test method Nude mice were subcutaneously inoculated with human colon cancer Ls-174t cells. After the tumors were grown to 150-300 mm 3 , the animals were randomly divided into groups (10:). The dosages and dosing schedules are shown in the table below. 2 - 3 tumor volume, weighing the mouse, record the data. The tumor volume (V) is calculated as:
- V l/2x a xb 2
- a and b represent length and width, respectively.
- CPT-11 liposome and CPT-11 significantly inhibited the growth of human colon cancer Ls-174t nude mice, and CPT-1 was dose-dependent. At high dose (3 mg/kg), there were 4/ 14 tumors partially resolved, low dose (lmg 10mg / kg equivalent, suggesting that CPT-11 liposome may be at least 10 times more effective than its injection, with
