Chemical Synthesis and DNA Photocleavage of the Intercalator–Carbohydrate Hybrid Moiety of the Neocarzinostatin Chromophore
This research was partially supported by a Grant-in-Aid for Encouragement of Young Scientists from the Ministry of Education, Science, Sports, and Culture, Japan, and a research grant of Keio University Special Grant-in-Aid for Innovative Collaborative Research Projects.
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.
