in a new class of developmental anticancer agents known as vascular disrupting agents (VDAs). Through a long-term program of structure activity relationship (SAR) driven inquiry, we discovered that the dihydronaphthalene molecular scaffold provided access to small-molecule inhibitors of tubulin polymerization. In particular, a dihydronaphthalene analogue bearing a pendant trimethoxy aryl ring (referred
天然产物秋水仙碱和考布他汀 A-4 ( CA4 ) 为发现和开发多种衍生物和类似物提供了灵感,这些衍生物和类似物通过 β-微管蛋白上秋水仙碱位点的结合相互作用抑制微管蛋白聚合。 CA4的水溶性磷酸前药盐(称为CA4P )已被证明能够选择性损伤肿瘤相关脉管系统,并开创了一类新的发育性抗癌药物,称为血管破坏剂 (VDA)。通过结构活性关系(SAR)驱动的长期研究计划,我们发现二氢萘分子支架提供了获得微管蛋白聚合的小分子抑制剂的途径。特别是,带有三甲氧基芳环侧垂的二氢萘类似物(称为KGP03 )和类似的芳酰环(称为KGP413 )是微管蛋白聚合的有效抑制剂(IC 50分别为 1.0 和 1.2 μM),并且表现出低 nM针对人类癌细胞系的细胞毒性。为了增强体内评价的水溶性,合成了相应的磷酸盐前药盐(分别为KGP04和KGP152 )。在对携带人乳腺肿瘤 MDA-MB-231-luc 的 SCID-BALB/c
