Based on the conformation of the α-methyl chalcone TUB091 in its complex with tubulin, a series of conformational mimetics have been designed and synthesized where the methyl group of the chalcone has been fused to phenyl ring B resulting in 1,2,3,4-tetrahydronaphthalen-2-yl aryl ketones. Among the synthesized compounds, the 5-amino-6-methoxy derivative, with a similar substitution pattern to that
基于α-甲基查尔酮TUB091与微管蛋白的复合物的构象,设计并合成了一系列构象模拟物,其中查尔酮的甲基已与苯环B稠合,形成1,2,3,4 -四氢萘-2-基芳基酮。在合成的化合物中,具有与TUB091相似的取代模式的5-氨基-6-甲氧基衍生物对肿瘤和内皮细胞显示约20 nM的抗增殖活性。微管蛋白结合实验证实其在秋水仙碱位点与微管蛋白结合,Kb为2.4×10 6 M -1导致抑制纯化的微管蛋白的体外组装。此外,基于最近报道的康普他汀A4(CA4)与微管蛋白的复合物,已经对CA4和α-甲基查尔酮与微管蛋白的结合方式进行了比较分析。
