compounds were found to have an activity comparable or higher than that of combretastatin A-4 in at least one of the aforementioned biological properties. The compounds with the (E)-arylalkene fragment were in general terms more active than the simple O-alkyl derivatives. However, no clear structure/activity correlations were perceived when comparing the observed compound activities across the three biological
我们在这里报告了几种在酚羟基烷基化的康维他汀A-4衍生物的合成和生物学评估。这些衍生物中的一些含有(E)-芳基烯烃片段,使人想起某些天然对苯二酚如白藜芦醇中存在的(E)-芳基烯烃片段。确定了对一种人类健康肾脏胚胎细胞和两种肿瘤细胞系的细胞毒性。另外,测量了这些化合物抑制血管内皮生长因子(VEGF)产生的能力。最后,测量了控制端粒酶产生的基因的表达。发现至少在上述生物学特性之一中,某些化合物具有与康普他汀A-4相当或更高的活性。带有(E的化合物)-芳基烯烃片段一般而言比简单的O-烷基衍生物更具活性。但是,比较观察到的三种生物学特性的化合物活性时,没有清晰的结构/活性相关性。这指出了造成细胞毒性的机制之间存在显着差异。
