A novel series of 5-substituted/unsubstituted [1,2,4]triazolo[3,4-b][1,3,4] thiadiazine compounds has been achieved successfully through chemoselective reduction of the C = N bond, based on our prior work. Initial biological evaluation illustrated that the most active derivative 7j exhibited significant cell growth inhibitory activity toward MCF-7, A549, HCT116, and A2780 with the IC50 values of 0
基于我们的研究,通过 C = N 键的化学选择性还原,成功获得了一系列新型 5-取代/未取代的[1,2,4]三唑并[3,4- b ][1,3,4]噻二嗪化合物。之前的工作。初步生物学评价表明,最活跃的衍生物7j对MCF-7、A549、HCT116和A2780表现出显着的细胞生长抑制活性,IC 50值分别为0.75、0.94、2.90和4.15 μM。最重要的是,所有代表性类似物均未表现出针对非肿瘤细胞系 HEK-293 的明显细胞毒活性(IC 50 > 100 μM)。机制研究表明,7j引起HeLa细胞G 2 /M期阻滞,以浓度依赖性方式诱导细胞凋亡,并显示出有效的微管蛋白聚合抑制作用。同时,7j在伤口愈合和管形成实验中发挥了显着的抗血管活性。这些观察结果表明,5-未取代的 6,7-二氢-5 H -[1,2,4]三唑并[3,4- b ][1,3,4]噻二嗪支架可能被认为是抗微管蛋白抑制剂
