吲哚马来酰亚胺类化合物的合成及其抗肿瘤活性

为寻找具有抗肿瘤活性的新化合物, 设计合成吲哚马来酰亚胺类化合物, 并评价其体外抗肿瘤活性. 以吲哚与2-氯乙酰胺为起始原料, 经取代、缩合等反应合成了单吲哚马来酰亚胺衍生物5a～5t, 以5-硝基吲哚和不同的N-(3-氯丙基)叔胺经取代、还原、缩合等反应得到了双吲哚马来酰亚胺衍生物9a～9f. 共合成了26个未见文献报道的新化合物, 其结构经质谱、元素分析和核磁共振氢谱确证. 采用MTT法, 测试了目标化合物对肿瘤细胞株HL60, ECA-109, A549, SMMC-7721和PC-3的增殖抑制活性, 结果表明部分化合物对所测肿瘤细胞株均显示一定的抑制作用.

Synthesis and Antitumor Activity of Indolemalylimide Derivatives

To discover novel compounds with antitumor activities, a series of indolylmaleimide derivatives were designed, synthesized and evaluated for their antitumor activities in vitro. Starting with indole and 2-chloroacetamide, followed by substitution and condensation, monoindolyl derivatives 5a～5t were syn-thesized. Starting with 5-nitroindole and different N-(3-chloropropyl)tertiary amines, followed by substitu-tion, reduction and condensation, diindolyl derivatives 9a～9f were synthesized. Twenty six novel com-pounds were synthesized, and their structures were confirmed by ESI-MS, elemental analysis and 1H NMR. The antitumor activities of the target compounds were evaluated with HL60, ECA-109, A549, SMMC-7721 and PC-3 in vitro. The in vitro antitumor activity showed that some compounds displayed inhibition to a certain degree against tested cells.
