Novel DNA-photocleaving molecule 1 consisting of a p-cyano substituted benzophenone photophore and an alkyl amino side chain was developed. DNA cleavage by 1 under photoirradiation conditions occurred selectively at 5' side G of 5'GG3' sequence after hot piperidine treatment. Photoirradiation of deoxyguanosine at 312 nm in the presence of 1 efficiently produced imidazolone as a predominant product. (C) 1998 Elsevier Science Ltd. All rights reserved.
