in the exploration of novel small molecules for oncotherapy. Based on the analysis of the binding models of tubulin and reported CBSIs, a series of 6-aryl-2-(3,4,5-trimethoxyphenyl)thiazole[3,2-b][1,2,4]triazoles were designed as potential tubulin polymerization inhibitors by binding to distinct colchicine domain of tubulin. Among the compounds synthesized, 7w not only shown noteworthy potency against
微管蛋白/秋水仙碱结合位点抑制剂 (CBSI) 共晶结构在探索用于肿瘤治疗的新型小分子中发挥着重要作用。基于对微管蛋白结合模型的分析和已报道的 CBSI,设计了一系列 6-aryl-2-(3,4,5-trimethoxyphenyl)thiazole[3,2- b ][1,2,4]triazoles通过与微管蛋白的不同秋水仙碱结构域结合,作为潜在的微管蛋白聚合抑制剂。在合成的化合物中,7w不仅对 SGC-7901 癌细胞系 (IC 50 = 0.21 μM) 表现出显着的效力,而且在正常细胞系 (HUVEC) 中表现出比秋水仙碱更低的细胞毒性。机制研究表明7w可通过抑制微管蛋白聚合引发 G 2 /M 阻滞,从而引起癌细胞凋亡。在 4T1 异种移植小鼠模型中,7w在不减轻体重的情况下显着抑制肿瘤生长,证明了在秋水仙碱结合位点具有独特结合模式的进一步开发的潜力。
