A series of novel 3-amido-4-indolylmaleimides have been synthesised from succinimide in five steps sequence consisting of bromination, indole addition, azide substitution, reduction and selective acylation. Cytotoxicity was evaluated for the products against cervical cancer Hela cell lines and human hepatocellular cancer SMMC 7721 cell line by standard MTT assay in vitro. Some of these compounds showed moderate cytotoxic potencies.
本研究以琥珀酰亚胺为原料,通过溴化、吲哚加成、叠氮取代、还原和选择性酰化五个步骤合成了一系列新型 3-氨基-4-吲哚马来酰亚胺。通过标准的 MTT 法,在体外评估了这些产品对宫颈癌 Hela 细胞系和人肝癌 SMMC 7721 细胞系的细胞毒性。其中一些化合物显示出中等程度的细胞毒性。
