polymerization and a potential anticancer activity. However, therapeutic application of CA4 is substantially hindered due to geometric isomerization. In the current study, new cis-restricted Combretastatin A4 analogues containing 1,2,4-triazle in place of the olefinic bond were designed and synthesized. The synthesized compounds were evaluated for their in vitro antiproliferative activity in human hepatocellular
Combretastatin A4(CA4)是一种天然产物,其特征在于可以显着抑制微管蛋白的聚合,并具有潜在的抗癌活性。但是,由于几何异构化,实质上阻碍了CA4的治疗应用。在当前的研究中,设计并合成了新的顺式限制性Combretastatin A4类似物,该取代物含有1,2,4-三唑代替烯烃键。使用MTT分析评估合成的化合物在人肝细胞癌HepG2和白血病HL-60细胞系中的体外抗增殖活性。此外,美国国家癌症研究所选择了14种化合物并测试了它们的抗增殖活性。一些测试的化合物显示出对六十种细胞系的中等活性。在HepG2细胞上评估了体外微管蛋白聚合抑制活性。该测定表明,与CA4相比,6a显示出显着的微管蛋白抑制作用。此外,细胞周期分析显示,HepG2细胞中类似物6c的G2 / M细胞周期明显停滞。分子对接结合基于AMBER的分子机械最小化结果显示了几种非共价相互作用,包括范德华力和微管蛋白β亚基
