comprehensive SAR investigation of the C2-position of pyrrolo[2,1-c][1,4]benzodiazepine (PBD) monomer antitumor agents is reported, establishing the molecular requirements for optimal in vitro cytotoxicity and DNA-binding affinity. Both carbocyclic and heterocyclic C2-aryl substituents have been studied ranging from single aryl rings to fused ring systems, and also styryl substituents, establishing across
吡咯烷[2,1- c]的C2位的SAR综合研究] [1,4]苯并二氮杂(PBD)单体抗肿瘤药物的报道,建立了最佳的体外细胞毒性和DNA结合亲和力的分子要求。碳环和杂环C2-芳基取代基的研究范围从单个芳基环到稠环系统,还有苯乙烯基取代基,在80个类似物库中建立,C2-芳基和苯乙烯基取代基可显着增强DNA结合亲和力和体外细胞毒性,两者之间具有相关性。发现DNA结合亲和力和细胞毒性的最佳C2分组是C2-喹啉基部分,根据分子模型,这是由于分子在DNA小沟中的整体适合性以及与功能性分子的潜在特异性接触所致。组在凹槽的地板和墙壁中。这个类似物(在HCT-116(bowel)人肿瘤异种移植模型中显示了14l)延迟肿瘤生长。
