studies on combilexines, compounds consisting of a DNA intercalator linked to a minor groove ligand, new results are presented. The synthesis of a series of new propylamine oligopyrrole carboxamides closely related to netropsin and distamycin A, linked to a heterocyclic or anthraquinone system is reported. The cytotoxic activity in vitro, the DNA binding characteristics and the inhibition of the topoisomerase
继续我们对梳状毒素的研究,该化合物由与小沟配体连接的DNA嵌入剂组成,并提供了新的结果。报道了一系列与netropsin和distamycin A密切相关的,与杂环或蒽醌系统连接的新丙胺低聚吡咯羧酰胺的合成。研究了化合物的体外细胞毒活性,DNA结合特性和对拓扑异构酶I的抑制作用,以解释这些新的潜在组合物的生物学作用机理。一些合成的化合物显示出对人肿瘤细胞系的细胞毒活性,以及DNA结合和拓扑异构酶I抑制特性。
