iso-CBI and iso-CI analogs of CC-1065 duocarmycins

摘要

A series of bioactive analogs of ()-CC-1065 (1) and the duocarmycins 2 and 3 are synthesized. The bioactive analogs include either iso-CI or iso-CBI (6 and 7) as a DNA alkylation subunit. Conjugated to the DNA alkylating subunits are a variety of DNA binding subunits. The bioactive analogs maintain their DNA selectivity and display enhance reactivity.
