title: Synthesis of a heterocyclic aza-enediyne and its DNA-cleavage properties.
abstract: The benzimidazolium salt 2, incorporating an aza-enediyne moiety, has been prepared and is shown to be a very effective DNA-cleavage agent under mild physiological conditions. Its mechanism of action is currently under investigation but may involve the generation of a diradical intermediate. DNA alkylation, or both.
