Abstract

Site-specific DNA cleavage is achieved in the presence of 1 upon irradiation with only long wavelength UV light; no supplementary metallic or reducing agents are required. Compound 1 possesses analogues of the intercalator and carbohydrate moieties found in neocarzinostatin, an antitumor enediene antibiotic.
