8-甲氧补骨脂素与小牛胸腺DNA的络合物的闪光光解实验表明,结合促进了8-MOP三线态的无氧猝灭,抑制了氧的可及性。结果表明,补骨脂素-DNA的暗相互作用抑制了先前工作中观察到的单线态氧的产生。
Abstract—Flash photolysis experiments on the complex of 8‐methoxypsoralen with calf thymus DNA have shown binding promotes the anaerobic quenching of the 8‐MOP triplet state and inhibits the accessibility to oxygen. The results indicate dark psoralen‐DNA interactions suppress the singlet oxygen generation observed in prior work.
