Abstract

cis-Diamminedichloroplatinum(II)-modified oligonucleotides contain-ing either a single intrastrand cross-link at the d(GpG) site or an interstrand cross-link at the d(GpC/GpC) site, were irradiated with 320 to 400-nm light. Upon irradiation, the adducts are photosensitive. Among the photo-induced reactions, the cleavage of the coordination bonds between platinum and the G residues in the interstrand cross-link is demonstrated.
