Abstract

Recent research on elucidation of mechanisms of the phototoxic activities of various pharmaceutical products currently being investigated in this laboratory is reviewed. Due to the importance of antibacterial quinolones of com mon use in present m edical practice, it is considered of general interest to summ arize the photochem ical reactions involved in the generation of active photoproducts and the possibility of metabolite mediation in biological damage. Thus, m echanism s are postulated for the photochemical decomposition of the substances investigated as well as the possible in vitro m echanism involved at cellular level.
