Description

本発明は、眼内レンズを着色するための色素に関し、特に紫外線及び青色領域光吸収能を有する重合性の色素に関する。   The present invention relates to a dye for coloring an intraocular lens, and more particularly to a polymerizable dye having an ability to absorb ultraviolet rays and blue light.

白内障は水晶体に混濁及び色素の形成と沈着が生じることにより、視界全体に霧がかかったような状態になる疾病である。その治療方法として、白濁した水晶体を除去し、眼内レンズ(IOL:Intraocular Lens)を水晶体嚢中に挿入・設置する手術が一般的に行われている。治療に用いられる眼内レンズ用材料の多くはアクリル系またはシリコン系ポリマーであり、特にポリメチルメタクリレート(PMMA)等が従前より使用されてきた。
ところが、本来の水晶体は紫外線を透過させない性質を有するのに対し、従前の眼内レンズ用ポリマーは紫外線を透過するため、網膜を損傷する危険性がある。
また、本来の水晶体は若干黄色味を帯びており、青色領域の光の一部を透過抑制する性質を有する。しかし従前の眼内レンズ用透明ポリマーはこの青色領域光をほぼ完全に透過させるため、眼内レンズ挿入術後に患者がまぶしさを訴える例が多かった。また、短波長で高エネルギーの青色領域光が眼内に到達すると黄斑変性症等の網膜由来の疾患を引き起こす危険性もあった。
そこで、眼内レンズ用材料には紫外線吸収能や黄色系色素による着色が求められるようになり、近年は安全性の観点から多くの眼内レンズ用ポリマーには紫外線吸収剤モノマーや黄色系色素モノマーが共重合されている。これまでにそのようなモノマー化合物が種々開発されており(特許文献1〜4)、一分子内にアゾ基等の発色団とベンゾフェノン骨格等の紫外線吸収部とを有する、他の眼内レンズ材料用モノマーとの共重合可能なモノマー化合物も開発されている(特許文献5、6)。
Cataract is a disease in which the entire visual field is fogged by turbidity and pigment formation and deposition in the lens. As a treatment method thereof, an operation is generally performed in which an opaque lens is removed and an intraocular lens (IOL) is inserted and placed in the lens capsule. Many of the intraocular lens materials used for treatment are acrylic or silicon-based polymers, and in particular, polymethyl methacrylate (PMMA) has been used for some time.
However, the original crystalline lens has the property of not transmitting ultraviolet rays, whereas the conventional polymer for intraocular lenses transmits ultraviolet rays, so there is a risk of damaging the retina.
In addition, the original crystalline lens is slightly yellowish and has a property of suppressing transmission of part of light in the blue region. However, conventional transparent polymers for intraocular lenses transmit this blue region light almost completely, so there are many cases in which patients complain of glare after intraocular lens insertion. There is also a risk of causing retina-derived diseases such as macular degeneration when blue light with high energy at a short wavelength reaches the eye.
In view of this, materials for intraocular lenses have been required to be colored with ultraviolet absorptive ability or yellow pigments. In recent years, from the viewpoint of safety, many polymers for intraocular lenses include ultraviolet absorber monomers and yellow pigment monomers. Are copolymerized. Various such monomer compounds have been developed so far (Patent Documents 1 to 4), and other intraocular lens materials having a chromophore such as an azo group and an ultraviolet absorbing portion such as a benzophenone skeleton in one molecule. Monomer compounds that can be copolymerized with other monomers have also been developed (Patent Documents 5 and 6).

特許文献5に記載の重合性紫外線吸収色素モノマーは、目的物の収率が低く工業的生産に耐えないという問題点がある。これは、複数のヒドロキシ基が存在するベンゾフェノン誘導体をジアゾニウム塩とジアゾカップリング反応させる工程において目的化合物の収率が低いことと、最終工程でアクリル酸やメタクリル酸等の重合性基をエステル化反応等で導入する際にベンゾフェノン骨格に置換しているフェノール性ヒドロキシ基とのエステル化反応が優位に起こり、大量の副産物が生じてしまうことに原因がある。
一方、特許文献6に記載のモノマーは、1級アルコール性ヒドロキシ基のみと反応するイソシアネート基を有するメタクリル酸誘導体を利用して、ヒドロキシ基を複数有する前駆体から重合性紫外線吸収色素モノマーを合成している。しかしながら、1級アルコール性ヒドロキシ基とイソシアネート基との反応の結果生ずるウレタン構造は、各種溶媒に対する溶解度を著しく低下させることが知られており、得られた重合性紫外線吸収色素モノマーのアクリル酸エチル等の他の重合性モノマーとの均一な混合液の調製を困難にしてい

そこで、本発明は、工業的生産に適し溶解性にも優れた重合性紫外線吸収色素モノマーを得ることを課題とする。
The polymerizable ultraviolet-absorbing dye monomer described in Patent Document 5 has a problem that the yield of the target product is low and it cannot withstand industrial production. This is because the yield of the target compound is low in the step of diazo coupling reaction with a diazonium salt of a benzophenone derivative with multiple hydroxy groups, and the esterification reaction of a polymerizable group such as acrylic acid or methacrylic acid in the final step. This is because the esterification reaction with the phenolic hydroxy group substituted on the benzophenone skeleton occurs preferentially and a large amount of by-products are produced.
On the other hand, the monomer described in Patent Document 6 uses a methacrylic acid derivative having an isocyanate group that reacts only with a primary alcoholic hydroxy group to synthesize a polymerizable UV-absorbing dye monomer from a precursor having a plurality of hydroxy groups. ing. However, the urethane structure resulting from the reaction between the primary alcoholic hydroxy group and the isocyanate group is known to significantly reduce the solubility in various solvents, such as ethyl acrylate as a polymerizable ultraviolet absorbing dye monomer obtained. It is difficult to prepare a uniform mixed solution with other polymerizable monomers.
Therefore, an object of the present invention is to obtain a polymerizable ultraviolet absorbing dye monomer suitable for industrial production and excellent in solubility.

The dye compound of the present invention has a benzophenone skeleton. Since the hydroxy group bonded to the benzene ring on the side to which the azo group of benzophenone is bonded is only one at the 2-position, side reactions in the diazo coupling step can be suppressed in the production method described later.

下記反応式(1)に上記好ましい合成工程の概略を示す。
The method for producing the dye compound of the present invention is not particularly limited. For example, a diazotization step of diazotizing an aminoaryl compound before introducing a polymerizable group to obtain a diazonium salt, the obtained diazonium salt and a benzophenone compound A diazo coupling step of diazo coupling to obtain a diazo compound, and esterification or introduction of a polymerizable group by reacting the obtained diazo compound with an acrylic acid compound or a methacrylic acid compound by an esterification reaction or an amidation reaction or the like It can be produced by a synthesis method including an amidation step.
Alternatively, a diazotization step of obtaining a diazonium salt by diazotizing an aminoaryl compound in which a polymerizable group has been previously introduced by an esterification reaction or an amidation reaction, and the obtained diazonium salt by diazo coupling with a benzophenone compound are used in the present invention. It can also be produced by a synthesis method including a diazo coupling step to obtain a dye compound. The latter synthesis method is preferable because the yield of the product is high. When the amino group of the aminoaryl compound is protected with a protecting group, the diazotization step can be performed after deprotection by acid treatment or the like. In the diazo coupling step, a base can be used as a catalyst. Among them, using a weak base such as sodium carbonate, potassium carbonate, sodium hydrogen carbonate, sodium acetate or potassium acetate can decompose the diazonium salt (polymerization). In order to prevent the decomposition or elimination of the functional group).
The outline of the preferable synthesis step is shown in the following reaction formula (1).

(式中、Rは水素原子または保護基を表し、R〜Rは前述と同様の置換基を表す。) (In the formula, R represents a hydrogen atom or a protecting group, and R 1 to R 3 represent the same substituents as described above.)

上記の本発明者らによる新たな合成方法によれば、予め重合性基をエステル化反応またはアミド化反応等で導入してからジアゾカップリング工程を行うため、従来法に見られる重合性基の導入時に起こる副反応を防ぐことができ、また、ベンゾフェノン化合物のアゾ基を導入する側のベンゼン環にヒドロキシ基が1つしかないことによりジアゾカップリング工程での副反応も抑えることができるので、反応効率が良く、高い収率で本発明の色素化合物を得ることができる。   According to the above-described new synthesis method by the present inventors, a diazo coupling step is performed after introducing a polymerizable group in advance by an esterification reaction or an amidation reaction. Since side reactions occurring at the time of introduction can be prevented and there is only one hydroxy group in the benzene ring on the side of introducing the azo group of the benzophenone compound, side reactions in the diazo coupling step can also be suppressed. The dye compound of the present invention can be obtained with high reaction efficiency and high yield.

本発明の色素化合物は、他の共重合モノマー一種又は二種以上と共重合させ、ポリマーにすることができる。   The dye compound of the present invention can be copolymerized with one or more other copolymerization monomers to form a polymer.

本発明の色素化合物は、他の共重合モノマーへの溶解性が高いため、ポリマー合成の際に共重合の反応性が良く、均一に本発明の色素化合物をポリマーに導入することができる。
また、本発明の色素化合物は、発色団と重合性基が立体的に離れているので、重合を阻害することがない。そのため他の共重合モノマーとの反応性のよい共重合モノマーとして使用することができる。
Since the dye compound of the present invention has high solubility in other copolymerization monomers, the copolymerization has good reactivity during polymer synthesis, and the dye compound of the present invention can be uniformly introduced into the polymer.
Moreover, since the chromophore and the polymerizable group are sterically separated, the dye compound of the present invention does not inhibit polymerization. Therefore, it can be used as a copolymerizable monomer having good reactivity with other copolymerizable monomers.
