摘要

利用纳秒级激光光解和脉冲辐解技术对放线菌素D（AMD）的模型化合物2—氨基—4，6—二甲基-3—吩噁嗪酮—1，9—二甲酸甲酯（ADE）的光物理性质进行了系统研究，确认了ADE光解时产生的瞬态物种，并测得了其激发三重态的自猝灭速率常数、摩尔消光系数和量子产额等重要光物理参数。这些结果将为详细了解ADE以及放线菌素D的光动力作用过程提供理论依据。

Abstract

By using of laser flash photolysis and pulse radiolysis techniques, a study of photophysics of ADE, which is a kind of model compound of actinomycin D, was carried out in varied solutions. The transient species generated by photolysis were identified, and the self—quenching rate constant, extinction coefficient and quantum yield of the triplet state ADE were determined. These results will be helpful for understanding the photodynamic processes of ADE and actinomycin D.
