A series of 1,2-heteroannelated anthraquinones and anthra[1,2-d]imidazole-6,11-dione tetracyclic analogues with different side chain were prepared using an various synthetic route via acylation, cyclization, condensation, and intramolecular heterocyclization. Tetracyclic system containing alkyl and aryl, aromatic and heterocyclic, linear and cyclic, polar and apolar, and basic and acids residues were
使用各种合成途径,通过酰化,环化,缩合和分子内杂环化,制备了一系列具有不同侧链的1,2-杂退火蒽醌和蒽[1,2 - d ]咪唑-6,11-二酮四环类似物。引入了包含烷基和芳基,芳族和杂环,线性和环状,极性和非极性以及碱性和酸性残基的四环体系。他们评估了它们对端粒酶活性,hTERT表达,细胞增殖以及对NCI 60细胞株人类肿瘤筛查的体外细胞毒性的影响。化合物4,11,12,14,15,16,17,19,20,23,25,和26是由NCI选择用于一个剂量筛选程序和进一步的研究4,23和25,其中曲线跨越这些线代表的内插值,以使50%生长抑制(GI 50),总生长抑制(TGI)和50%细胞杀伤率(LC 50), 分别。进一步的研究未发现任何显示出对端粒酶抑制活性和hTERT抑制能力有效且显着的化合物。在NCI的筛选中对这些化合物进行的对比测试显示出不同的效力水平和不同的细胞毒性作用,显然与核心环
