The synthesis and cytotoxic properties of benzimidazole-based DNA-cleavingagents are presented herein. These agents include pyrrolo[1,2-a]benzimidazole (PBI), benzimidazole (BI), and tetrahydropyrido[1,2-a]benzimidazole (TPBI) analogues. As a result of these studies, it is concluded that the pyrrolo ring is not necessary for cytotoxicity (PBI is only slightly more cytotoxic than BI) but that homologation
