A series of cis restricted 1,2,4-triazole analogs of combretastatin A-4 (CA-4) were designed and synthesized. The antiproliferative activity of these compounds was measured on hepatocellular carcinoma HepG2, leukemia HL-60, and breast cancer MCF-7 cell lines. The obtained results showed a substantial ability of the synthesized anilides to inhibit tumor growth. On HepG2 cells, 5o and 5r showed potent
设计并合成了一系列康布雷他汀A-4(CA-4)的顺式限制性1,2,4-三唑类似物。在肝细胞癌HepG2,白血病HL-60和乳腺癌MCF-7细胞系中测量了这些化合物的抗增殖活性。所获得的结果显示了合成的酸酐具有抑制肿瘤生长的实质能力。在HepG2细胞上,5o和5r的有效IC50值分别为0.10和0.04μM。在HL-60细胞上,5b和5i的IC50值分别为0.004和0.01μM。在HepG2细胞上评估了微管蛋白聚合的抑制活性。与CA-4相比,苯胺5r表现出显着的微管蛋白抑制作用。此外,流式细胞术研究表明,用最有效的化合物5b和5r处理的HepG2细胞停滞在细胞周期的G2 / M期。该作用伴随细胞凋亡和caspase-3的活化。分子建模显示了微管蛋白的秋水仙碱结合位点内的几个氢键和范德华力与几个重要氨基酸的相互作用。
