Demonstration and definition of the noncovalent binding selectivity of agents related to CC-1065 by an affinity cleavage agent: noncovalent binding coincidental with alkylation

Bioorg Med Chem. 1996 Jun;4(6):859-67. doi: 10.1016/0968-0896(96)00073-9.

Abstract

A study of the DNA cleavage efficiency and selectivity of CDPI3-EDTA (4), an affinity cleavage agent based on the structure of CC-1065, is described. The studies with 4 provide direct evidence of AT-rich noncovalent binding coincidental with all DNA alkylation sites observed with (+)- or ent-(-)-CC-1065.
