The quinoxaline moiety in antitumor quinoxaline antibiotics cleaved double stranded DNA at the 5' side guanine of the 5'-GG-3' site upon irradiation with UV light with a long wavelength and without any additive. The quinoxaline-carbohydrate hybrid system was very effective for the DNA cleavage. Furthermore, the quinoxaline-carbohydrate hybrids exhibited strong and selective cytotoxicity against cancer cells with photoirradiation. (C) 2003 Elsevier Science Ltd. All rights reserved.
