found to be the ideal structural features. The most potent compounds (A-2, A-3 and A-7) were further tested for tubulin polymerization inhibition. Compound A-2 was found to significantly inhibit the tubulin polymerization (IC50 = 0.82 μM in THP-1 tumor cells). The significant cytotoxicity and tubulin polymerization inhibition by A-2 was further rationalized by docking studies where it was docked at
鉴于保持与当前访问的抗肿瘤剂和C的成功结盟的界限5 -curcuminoid基于双官能杂合体是新颖抗微管蛋白agnets,C的分子杂交5合成了由三唑环束缚的-curcuminoidoid和香豆素,并研究了它们对THP-1,COLO-205,HCT-116和PC-3人肿瘤细胞系的体外细胞毒性。结果显示,化合物A-2至A-9,B-2,B-3,B-7对THP-1,COLO-205和HCT-116细胞系表现出显着的细胞毒性,而PC-3细胞发现其中的品系几乎是抗性的。结构活性关系表明,X环的性质和连接三唑环与香豆素部分的碳桥长度(n)极大地影响了该活性。发现甲氧基取代的苯环(如X环)和两个碳桥是理想的结构特征。进一步测试了最有效的化合物(A-2,A-3和A-7)对微管蛋白聚合的抑制作用。 在THP-1肿瘤细胞中50 = 0.82μM)。通过对接研究进一步合理化了A-2对细胞毒性和微管蛋白聚合的抑制作
