Establishment of substituent effects in the DNA binding subunit of CBI analogues of the duocarmycins and CC-1065
摘要:
An extensive series of CBI analogues of the duocarmycins and CC-1065 exploring substituent effects within the first indole DNA binding subunit is detailed. In general, substitution at the indole C5 position led to cytotoxic potency enhancements that can be greater than or equal to 1000- fold providing simplified analogues containing a single DNA binding subunit that are more potent (IC50 = 2-3 pM) than CBI-TMI, duocarmycin SA, or CC-1065.
