In an attempt to develop potent anti-tubulin agents against most dreadful disease cancer, a library of 28 novel triazole tethered isatin-coumarin hybrids were synthesized by click chemistry approach. Synthesized hybrids were characterized and evaluated against a panel of human cancer cell lines viz. THP-1, COLO-205, HCT-116 and PC-3. Biological assay unveiled that, compounds A-1 to A-6, B-1 to B-4
为了开发针对大多数可怕疾病癌症的有效抗微管蛋白药物,通过点击化学方法合成了28种新颖的三唑系留的伊斯汀-香豆素杂种的文库。表征合成的杂种并针对一组人类癌细胞系进行评估。THP-1,COLO-205,HCT-116和PC-3。生物测定揭示化合物A-1至A-6,B-1至B-4和C-1至C-3对THP-1,COLO-205和HCT-116细胞系显示出显着的抑制潜力,而THP-1,COLO-205和HCT-116细胞系对设计的杂种更敏感。发现这些细胞系中的PC-3几乎具有抗性。建立的SAR显示出细胞毒性活性对伊斯丁上取代基的类型和与三唑环连接的伊斯丁部分的碳桥长度的显着依赖性。发现未取代的靛红和两个碳桥对于细胞毒性至关重要。进一步测试了三种最有效的杂种(A-1,A-2和B-1)对微管蛋白聚合的抑制作用。在这三种化合物中,IC 50赋予A-1最显着的微管蛋白聚合抑制潜能值1.06 µM,通过共聚焦显
