The design, synthesis and biological evaluation of novel pyrrolo [2,1][1,4] benzodiazepine (PBD) dimers 38-43 linked with pyrrole and imidazole polyamides from either side by a flexible methylene chain of variable length are described, which involved mercuric chloride mediated cyclization of the corresponding amino diethyl thioacetals. The compounds were prepared with varying numbers of pyrrole and
描述了新型吡咯并[2,1] [1,4]苯二氮杂(PBD)二聚体38-43与吡咯和咪唑聚酰胺通过可变长度的柔性亚甲基链从任一侧连接的设计,合成和生物学评估,涉及氯化汞介导的相应氨基二乙基硫缩醛的环化。用不同数量的含吡咯和咪唑的聚酰胺制备化合物,以确定最佳体外抗肿瘤活性的结构要求。这些化合物由美国国家癌症研究所针对60个人类癌细胞进行了测试,证明了化合物bis-PBD-吡咯聚酰胺(38-40)和bis-PBD-咪唑聚酰胺(41-43)中的某些bis-PBD-吡咯和咪唑聚酰胺共轭物对单个癌细胞系具有活性(表1)。
