Abstract
A new class of sequence-specific DNA alkylating agents were developed based on the reactivity of duocarmycin A and the DNA-reading ability of pyrrole-imidazole polyamide. The DNA alkylation sequence specificity by duocarmycin A can be modulated by a variety of pyrrole-imidazole triamides in a predictable manner. Novel hybrids of the segment A of duocarmycin A and pyrrole-imidazole polyamides efficiently and highly selectively alkylated the target base possessing match sequences of Dervan's binding code.
