Description
技术领域
本发明涉及药物化学技术领域,尤其涉及一种含硫类青蒿素二聚体、其制备方法和应用。
背景技术
上世纪七十年代,从黄花蒿中提取出青蒿素,并在实验室和临床证实青蒿素具有强大的抗疟作用,并在此结构基础上又相继合成、半合成出一系列具有抗疟活性的衍生物,如双氢青蒿素、青蒿琥酯、蒿甲醚、蒿乙醚等。
在青蒿素类药物的抗疟作用被证实之后,其它生物活性如抗其它寄生虫、抗癌和免疫抑制的研究也随之开展。
Woerdenbag HJ等报道青蒿素、蒿甲醚、蒿乙醚、青蒿琥酯对Ehrlich Ascites细胞株有一定的细胞毒性,11,13-脱氢青蒿素(Artemisitene)的作用更强,双氢青蒿素的二聚体则显示最强活性[1]。
为了寻找具有更高活性的化合物,数以百计的青蒿素类化合物被合成及筛选,特别是近十年以来,一些采用不同连接物组成的青蒿素二聚体和三聚体被大量报道,其中有不少化合物对人癌细胞株的生长具有强大的选择性抑制作用。

本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物,包括顺式和反式异构体、(-)-和(+)-对对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,及其外消旋混合物和其他混合物,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本发明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本发明的范围之内。
除非另有说明,术语“对映异构体”或者“旋光异构体”是指互为镜像关系的立体异构体。
除非另有说明,术语“顺反异构体”或者“几何异构体”系由因双键或者成环碳原子单键不能自由旋转而引起。
除非另有说明,术语“非对映异构体”是指分子具有两个或多个手性中心,并且分子间为非镜像的关系的立体异构体。
除非另有说明,“(D)”或者“(+)”表示右旋,“(L)”或者“(-)”表示左旋,“(DL)”或者“(±)”表示外消旋。
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D-和L-异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通对使用色谱法完成的,所色谱法来用手性固定相,并任选地与化学衍生相结合(例如由胺生成氨基甲酸盐)。

术语“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
术语“被取代的”是指特定原子上的任意一个或多个氢原于被取代基取代,可以包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即=O)时,意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代,也可以不被取代,除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R1)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0~2个R1所取代,则所述基团可以任选地至多被两个R1所取代,并且每种情况下的R1都有独立的选项。此外,取代基和/或其变体的组合只有在这梯的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时,比如-(CR1 2)0-,表示该连接基团为单键。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比A-L-B中L代表单键时表示该结构实际上是A-B。
当一个取代基为空缺时,表示该取代基是不存在的,比如A-C中C为空缺时表示该结构实际上是A。
当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。当所列举的连接基团没有指明其连接方向,其连接方向是任意的。
所述连接基团、取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
除非另有规定,术语“C1~C10烷基”用于表示直链或支链的由1至10个碳原子组成的饱和碳氢基团。其可以是一价(如甲基)、二价(如亚甲基)或者多价(如次甲基)。

实验例
化合物1-55的抗癌活性测试
实验原理:
MTS法检测细胞活性原理:MTS为一种全新的MTT类似物,全称为3-(4,5-dimethylthiazol-2-yl)-5(3-carboxymethoxyphenyl)-2-(4-sulfopheny)-2H-tetrazolium,是一种黄颜色的染料。活细胞线粒体中琥珀酸脱氢酶能够代谢还原MTS,生成可溶性的甲臜(Formazan)化合物,甲臜的含量可以用酶标仪在490nm处进行测定。在通常情况下,甲臜生成量与活细胞数成正比,因此可根据光密度OD值推测出活细胞的数目。
实验方法:
接种细胞:用含10%胎牛血清的培养液(DMEM或者RMPI1640)配成单个细胞悬液,
以每孔3000~15000个细胞接种到96孔板,每孔体积100ul,贴壁细胞提前12~24小时接种培养。
加入待测化合物溶液:化合物用DMSO溶解,化合物以40uM浓度初筛,每孔终体积200ul,每种处理均设3个复孔。
显色:37℃培养48小时后,贴壁细胞弃孔内培养液,每孔加MTS溶液20ul和培
养液100ul;悬浮细胞弃100ul培养上清液,每孔加20ul的MTS溶液;设3个空白复孔(MTS溶液20ul和培养液100ul的混合液),继续孵育2~4小时,使反应充分进行后测定光吸收值。
比色:选择492nm波长,多功能酶标仪(MULTISKAN FC)读取各孔光吸收值,记录结果,最终取3次结果的平均值。
阳性对照化合物:每次实验均设顺铂(DDP)和紫杉醇(Taxol)两个阳性化合物。
