E-cadherin and down-regulating N-cadherin. Furthermore, the tubulin polymerization inhibitory activity in vitro of 10b was 2.4 μM. In vivo anticancer assay, 10b effectively inhibited MGC-803 xenograft tumor growth without causing significant loss of body weight. These sulfanilamide-1,2,3-triazole hybrids as potent tubulin polymerization inhibitors might be used as promising candidates for cancer therapy
微管作为癌症治疗中的重要靶标,被用于设计新型微管蛋白聚合抑制剂。通过分子杂交策略设计了磺胺基1,2,3-三唑杂化物,并评估了它们对三种选定的癌细胞系(BGC-823,MGC-803和SGC-7901)的抗增殖活性。所有磺胺-1,2,3-三唑杂种均表现出对所有细胞系的有效抑制活性。尤其是,化合物10b对MGC-803细胞表现出最优异的抑制作用,IC50值为0.4μM。细胞机制研究阐明了10b通过降低Bcl-2和Parp的表达水平并增加BAX的表达水平诱导凋亡。10b通过上调E-cadherin和下调N-cadherin抑制上皮-间质转化过程。此外,10b的体外微管蛋白聚合抑制活性为2.4μM。在体内抗癌试验中,10b有效抑制MGC-803异种移植肿瘤的生长,而不会引起体重的明显下降。这些有效的微管蛋白聚合抑制剂的磺胺-1,2,3-三唑杂化物可以用作癌症治疗的有希望的候选物。
