The synthesis and structure-activity relationship study of a series of compounds with heterocycles in place of the cis double bond in combretastatin A-4 (CA-4) are described. Substituted tosylmethyl isocyanides were found to be the key intermediates in construction of the heterocycles. Cytotoxicities of the heterocycle-based CA-4 analogues were evaluated against NCI-H460 and HCT-15 cancer cell lines
描述了一系列具有杂环取代康维他汀A-4(CA-4)中的顺式双键的化合物的合成和构效关系研究。发现取代的甲苯磺酰基甲基异氰化物是构建杂环的关键中间体。评价了基于杂环的CA-4类似物对NCI-H460和HCT-15癌细胞系的细胞毒性。3-氨基-4-甲氧基苯基和N-甲基-吲哚-5-基是CA-4中3-羟基-4-甲氧基苯基的最佳替代品。发现4,5-二取代的咪唑是替代CA-4中的顺式双键的最佳选择。药物化学的努力导致发现化合物24h和25f在大鼠中的生物利用度分别为32%和82%。
