摘要: 分析了鬼臼毒素及其衍生物与还原性自由基(氢自由基、水合电子)作用、氧化性自由基羟基自由基和激光等作用后产生的各种瞬态粒子,对各粒子的生成和衰减过程进行跟踪,获得了各瞬态粒子的生成和衰减速率常数,进一步探讨了鬼臼毒素治疗肿瘤的构效关系.

关键词: 鬼臼毒素及其衍生物, 脉冲辐解, 激光光解, 瞬态粒子

Abstract: The transient species of podophyllotoxin and its derivatives were analyzed by pluse radiolysis and laser photolysis.The podophyllotoxin and its derivatives can react with hydrated electron, hydrogen radical and hydroxyl radical, and they can be photo-ionized by laser.We have studied their reaction mechanisMAnd gotten their forming and decay rate constants.

Key words: Podophyllotoxin and its derivatives, Pulse radiolysis, Laser photolysis, Transient species
