the bithiazole nucleus, apparently in a stoichiometric fashion. Inhibition of DNAcleavage in the presence of DMSO, as well as photoaddition to 1-octene by both brominated and chlorinatedbithiazole derivatives, suggest strongly that the initial step in photoactivated DNAcleavage involves homolysis of the thiazole carbon-halogen bond. The chlorinatedbithiazoles were found to mediate sequence selective
