synthesized and their cytotoxic activities in vitro against four different cell lines (HT-29, MCF-7, NIH-3T3, AGS) were evaluated. Compound 6g bearing 3,4,5-trimethoxyphenyl moiety on ring A and 4-methoxy substituent on ring B displayed potent cytotoxic activity against all cell lines. Flow cytometry analysis and microtubule polymerization assay confirmed that cytotoxic activities of this compound were
合成了一系列新的4-芳基-5-(3,4,5-三甲氧基苯基)-2-烷硫基-1 H-咪唑,它们在体外对四种不同的细胞系(HT-29,MCF-7,评估NIH-3T3,AGS)。化合物6g在环A上带有3,4,5-三甲氧基苯基部分,在环B上带有4-甲氧基取代基,显示出对所有细胞系有效的细胞毒活性。流式细胞仪分析和微管聚合测定证实该化合物的细胞毒性活性与对微管聚合的抑制作用有关。分子模型研究表明,化合物6g可通过与Thrα179和Cysβ241的氢键相互作用而与α,β-微管蛋白的秋水仙碱结合位点牢固结合。
