应理解,在本发明范围内中,本发明的上述各技术特征和在下文(如实施例)中具体描述的各技术特征之间都可以互相组合,从而构成新的或优选的技术方案。限于篇幅,在此不再一一累述。
与现有技术相比,本发明具有以下优点:
(1)本发明提供了一种多酚取代的3-芳基-2-芳基甲基丙烯类化合物,这类化合物的显著特点是都含有至少两个酚羟基。这类化合物含如下两个小类:(i)两个苯环上的取代基相同,得到对称的多酚取代的3-芳基-2-芳基甲基丙烯类化合物;(ii)两个苯环上的取代基不相同,得到不对称的多酚取代的3-芳基-2-芳基甲基丙烯类化合物。这些化合物显示出对肿瘤细胞株有较好的抑制增殖的活性。

对于第(ii)类化合物而言,合成步骤比第(i)类化合物要多一步,难度相对较大,产物收率也较低一些。
具体的实施方法是:经过化学合成,制备出苯环上含有不同取代基的3-芳基-2-芳基甲基丙烯多酚类化合物。
在这个苯环的取代基中,可以嵌入含有N、O、S杂原了的极性官能团或结构片段,包括烷基、支链烷基、环烷基、杂环基(含有个数为1-10个的选自N、O、S的杂原了、芳基、杂芳基、烯基、炔基、酰胺键、酯基等,以及这些基团的组合所形成的基团或结构片段。这些多酚取代的3-芳基-2-芳基甲基丙烯类化合物保留了该化合物的基本骨架。同时在苯环上引入的杂原了和各种结构片段,对于提高水溶性、或者改善与生物体的蛋白质的相互作用,起到一定的作用。本发明对这类化合物的生物活性,特别是抗肿瘤活性进行了研究,有望开发出治疗人类疾病的新药。
