and synthesis of several new disubstituted analogues of 1, along with their biological evaluation as potential antivascular agents. Compound 13, bearing a hydroxyl group at the 7-position of the indole nucleus that mimics the hydroxyl group at the 3-position of the B-ring of CA-4, was identified as a potent inhibitor of tubulin polymerization and also as a cytotoxic agent against B16 melanoma cells at
6-甲氧基-3-(3',4',5'-三甲氧基苯甲酰基)-1H-吲哚(BPR0L075)(1)是微管蛋白聚合的有效抑制剂,对多种固体均表现出体内和体外活性肿瘤。该化合物被设计为康普他汀A4(CA-4)的杂环类似物,康普他汀A4是一种天然的二苯乙烯衍生物,可破坏肿瘤的脉管系统并导致肿瘤消退。在目前的工作中,我们描述了几种新的1的双取代类似物的设计和合成,以及它们作为潜在抗血管药物的生物学评估。化合物13在吲哚核的7位带有一个羟基,该羟基模仿CA-4 B环的3位上的羟基,被认为是微管蛋白聚合的有效抑制剂,也是亚微摩尔浓度的针对B16黑色素瘤细胞的细胞毒剂。此外,化合物13在纳摩尔浓度的内皮细胞(EA.hy 926细胞)上显示出明显的形态学活性(向上舍入),这表明潜在的抗血管活性。有趣的是,尽管在微管蛋白聚合抑制试验中具有中等活性,但在细胞测定中也发现了相应的7-O-甲磺酸酯衍生物28(13的合成
