anticancer activity of a series of new combretastatin derivatives with B-ring modifications. The structure-activity relationship (SAR) information confirmed the importance of cis-stereochemistry and of a phenolic moiety in B-ring. We selected the benzo[b]thiophene and benzofuran combretastatin analogues 11 (ST2151) and 13 (ST2179) and their phosphate prodrugs (29 and 30) for their high antitumor activity
我们研究了一系列具有B环修饰的新型康美他汀衍生物的抗癌活性。结构-活性关系(SAR)信息证实了B环中顺式立体化学和酚类部分的重要性。我们选择了苯并[b]噻吩和苯并呋喃康他汀类似物11(ST2151)和13(ST2179)以及它们的磷酸盐前药(29和30),因为它们在体外和体内模型中具有很高的抗肿瘤活性。细胞暴露于11、13和CA-4的IC50会导致各种类型的细胞停滞在细胞周期的G2 / M期,并诱导凋亡。相对于CA-4,主要是11和13诱导了染色质分布异常的多核细胞的形成,对微管组织的影响很小。有趣的是,
