Synthesis of C8-linked pyrrolo[2,1-c][1,4]benzodiazepine-benzimidazole conjugates with remarkable DNA-binding affinity.
Two types of benzimidazoles have been synthesized and linked to DC-81 at C8-position through different alkyl chain spacers. These PBD conjugates have exhibited remarkable DNA-binding affinity, and a representative compound shows promising in vitro anticancer activity.
