摘要

综述了近年来在本实验室研究的各种药物的光毒性作用机理的研究进展。鉴于目前医学实践中常用的抗菌喹诺酮类药物的重要性,总结活性光产物生成过程中涉及的光化学反应以及代谢物介导生物损伤的可能性被认为是普遍感兴趣的。因此,我们假设了所研究物质的光化学分解机制以及可能涉及细胞水平的体外机制。

MECHANISTIC STUDIES ON PHOTOTOXICITY INDUCED BY ANTIBACTERIAL QUINOLONES
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.
