Description

偶氮化合物、聚合物和制备方法及用途 技术领域
本发明涉及眼部医疗器件领域,具体地,涉及偶氮化合物、聚合物和制备方法及用途。
背景技术
近年来,有研究显示可见光中的蓝光部分能够对人眼,特别是视网膜造成损害,导致视力下降甚至失明。因此出现了在眼镜镜片等眼部医疗器件中,添加能够拦截蓝光的贴膜或能够拦截蓝光的成分,防止蓝光对人眼造成伤害。
然而,目前具有蓝光拦截功能的眼部医疗器件及制备眼部医疗器件的聚合物仍有待改进。
发明内容
本申请是基于发明人对以下事实和问题的发现和认识作出的:
虽然目前具有蓝光拦截功能的眼镜镜片较为普遍,但人工晶体等直接与人眼接触的眼部医疗器件中,蓝光拦截功能较为少见。发明人经过深入研究发现,这主要是由于蓝光的拦截功能普遍是通过在眼部医疗器件中添加具有吸收蓝光功能的黄色染料而实现的。而上述直接与人眼接触的眼部医疗器件,要求添加的黄色染料不能够在眼部医疗器件中发生扩散以及迁移,也即是说,需要保证添加的黄色染料稳定存在在上述眼部医疗器件中,不会进入人眼,以便保证上述眼部医疗器件的安全性能。而能够满足上述要求的黄色染料十分有限,因此限制了具有蓝光拦截功能的眼部医疗器件的发展。
本发明旨在至少在一定程度上解决以上相关技术中的技术问题之一。为此,本发明提出一种偶氮化合物,该偶氮化合物具有较好的拦截蓝光性能,且上述化合物为可聚合的偶氮化合物,不易在聚合物中发生迁移扩散,因此可以作为人工晶体等眼部医疗器件中的蓝光吸收剂使用。
本发明还提出一种聚合物,该聚合物含有上述偶氮化合物,因此具有拦截蓝光的功能。且上述偶氮化合物为可聚合化合物,因此上述偶氮化合物不易在本发明提出的聚合物中发生扩散迁移。
本发明还提出本发明所述聚合物在制备眼部医疗器件中的用途。利用上述聚合物制备 眼部医疗器件,可以在不影响该眼部医疗器件的使用功能的前提下,实现蓝光的拦截功能,并具有较好的安全性。
此外,本发明还提出制备本发明所述聚合物的方法。

具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
除非另外说明,本发明所使用的所有科技术语具有与本发明所属领域技术人员的通常理解相同的含义。本发明涉及的所有专利和公开出版物通过引用方式整体并入本发明。术语“包含”或“包括”为开放式表达,即包括本发明所指明的内容,但并不排除其他方面的内容。在本发明中,无论是否使用“大约”或“约”等字眼,所有在此公开了的数字均为近似值。每一个数字的数值有可能会出现10%以下的差异或者本领域人员认为的合理的差异,如1%、2%、3%、4%或5%的差异。
在本发明中,本发明所提出的偶氮化合物具有式Ia所示的通式,也包括符合式Ia所示通式化合物的立体异构体或互变异构体。“立体异构体”是指具有相同化学构造,但原子或基团在空间上排列方式不同的化合物。立体异构体包括对映异构体、非对映异构体、构象异构体(旋转异构体)、几何异构体(顺/反)异构体以及阻转异构体等。
本发明所使用的立体化学定义和规则一般遵循S.P.Parker,Ed.,McGraw-Hill Dictionary of Chemical Terms(1984)McGraw-Hill Book Company,New York;and Eliel,E.and Wilen,S.,“Stereochemistry of Organic Compounds”,John Wiley&Sons,Inc.,New York,1994中所描述的立体化学定义和规则。
许多有机化合物以光学活性形式存在,即它们具有使平面偏振光的平面发生旋转的能 力。在描述光学活性化合物时,使用前缀D和L,或R和S来表示分子关于其一个或多个手性中心的绝对构型。前缀d和l或(+)和(-)是用于指定化合物所致平面偏振光旋转的符号,其中(-)或l表示化合物是左旋的。前缀为(+)或d的化合物是右旋的。一种具体的立体异构体是对映异构体,这种异构体的混合物称作对映异构体混合物。对映异构体的50:50混合物称为外消旋混合物或外消旋体,当在化学反应或过程中没有立体选择性或立体特异性时,可出现这种情况。
本发明公开化合物的任何不对称原子(例如,碳等)都可以以外消旋或对映体富集的形式存在,例如(R)-、(S)-或(R,S)-构型形式存在。在某些实施方案中,各不对称原子在(R)-或(S)-构型方面具有至少50%对映体过量,至少60%对映体过量,至少70%对映体过量,至少80%对映体过量,至少90%对映体过量,至少95%对映体过量,或至少99%对映体过量。
依据起始物料和方法的选择,本发明化合物可以以可能的异构体中的一个或它们的混合物,例如外消旋体和非对应异构体混合物(这取决于不对称碳原子的数量)的形式存在。光学活性的(R)-或(S)-异构体可使用手性合成子或手性试剂制备,或使用常规技术拆分。如果化合物含有一个双键,取代基可能为E或Z构型;如果化合物中含有二取代的环烷基,环烷基的取代基可能有顺式或反式构型。
所得的任何立体异构体的混合物可以依据组分物理化学性质上的差异被分离成纯的或基本纯的几何异构体,对映异构体,非对映异构体,例如,通过色谱法和/或分步结晶法。
可以用已知的方法将任何所得终产物或中间体的外消旋体通过本领域技术人员熟悉的方法拆分成光学对映体,如,通过对获得的其非对映异构的盐进行分离。外消旋的产物也可以通过手性色谱来分离,如,使用手性吸附剂的高效液相色谱(HPLC)。特别地,对映异构体可以通过不对称合成制备,例如,可参考Jacques,et al.,Enantiomers,Racemates and Resolutions(Wiley Interscience,New York,1981);Principles of Asymmetric Synthesis(2nd Ed.Robert E.Gawley,Jeffrey Aubé,Elsevier,Oxford,UK,2012);Eliel,E.L.Stereochemistry of Carbon Compounds(McGraw-Hill,NY,1962);Wilen,S.H.Tables of Resolving Agents and Optical Resolutions p.268(E.L.Eliel,Ed.,Univ.of Notre Dame Press,Notre Dame,IN 1972);Chiral Separation Techniques:A Practical Approach(Subramanian,G.Ed.,Wiley-VCH Verlag GmbH&Co.KGaA,Weinheim,Germany,2007)。
术语“互变异构体”或“互变异构形式”是指具有不同能量的可通过低能垒(low energy barrier)互相转化的结构异构体。若互变异构是可能的(如在溶液中),则可以达到互变异构体的化学平衡。例如,质子互变异构体(protontautomer)(也称为质子转移互变异构体 (prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。价键互变异构体(valence tautomer)包括通过一些成键电子的重组来进行的互相转化。酮-烯醇互变异构的具体实例是戊烷-2,4-二酮和4-羟基戊-3-烯-2-酮互变异构体的互变。互变异构的另一个实例是酚-酮互变异构。酚-酮互变异构的一个具体实例是吡啶-4-醇和吡啶-4(1H)-酮互变异构体的互变。除非另外指出,本发明化合物的所有互变异构体形式都在本发明的范围之内。
在本发明中,无论是否使用“大约”或“约”等字眼,所有在此公开了的数字均为近似值。每一个数字的数值有可能会出现10%以下的差异或者本领域人员认为的合理的差异,如1%、2%、3%、4%或5%的差异。术语“蓝光”是指波长范围在400~550nm的可见光,“拦截蓝光”、“吸收蓝光”等术语指当含有蓝光的可见光,由本发明提出的偶氮化合物或聚合物等物质构成的材料表面一侧入射并穿过该材料时,在材料另一侧表面的出射光中蓝光的光强较入射光中蓝光的光强相比具有明显的降低,甚至出射光中不包含蓝光。本发明中“室温”指的是温度由大约10摄氏度到大约40摄氏度。在一些实施例中,“室温”指的是温度由大约20摄氏度到大约30摄氏度;在另外一些实施例中,“室温”指的是20摄氏度,22.5摄氏度,25摄氏度,27.5摄氏度等等。
