We report the efficient synthesis involving palladium-catalyzed reactions and biological evaluation of new naphthocarbazoles designed as potential anticancer agents. The use of 5- and 6-benzyloxyindoles generated three substitution sites which were successively exploited to introduce several hydrophilic side chains. The cytotoxicity of the newly designed compounds was evaluated on three cell lines. Several
我们报告了涉及钯催化反应的高效合成以及被设计为潜在抗癌药的新萘并咔唑的生物学评估。5-和6-苄氧基吲哚的使用产生了三个取代位点,这些取代位点被连续利用以引入几个亲水性侧链。在三种细胞系中评估了新设计化合物的细胞毒性。几种化合物显示出明显的细胞毒性,其IC(50)值在亚微摩尔范围内。带有二甲基氨基乙基侧链的3-羟基-萘并吡咯并咔唑二酮37就是这种情况,它对L1210和DU145细胞具有极强的细胞毒性(IC(50):36 nM,108 nM),并诱导G2中L1210细胞的积累细胞周期的+ M个阶段。测试了一些最具细胞毒性的化合物对CDK-5的抑制作用,还评估了GSK-3和拓扑异构酶I,以及它们与DNA的相互作用。检测到与DNA的相互作用,表明核酸代表了这些分子的优先靶标。
