A series of CBI analogues of the duocarmycins and CC-1065 exploring substituent effects within the first indole DNA binding subunit are detailed. Substitution at the indole C5 position led to cytotoxic potency enhancements that are > or =1000-fold, providing simplified analogues containing a single DNA binding subunit that are more potent (IC(50)=2-3 pM) than CBI-TMI, duocarmycin SA, or CC-1065.
详细介绍了一系列探索第一个吲哚DNA结合亚基内取代基效应的双咔霉素和CC - 1065的CBI类似物。在吲哚C5位置进行取代导致细胞毒性效力增强超过或等于1000倍,从而提供了含有单个DNA结合亚基的简化类似物,其比CBI - TMI、双咔霉素SA或CC - 1065更具效力(IC(50)=2 - 3 pM)。
