代谢
1. 在体外,大鼠肝脏酶对pyridine的转化产生了相应的单酸作为主要代谢物。
2. dithiopyr中甲基硫酯功能团转化为单酸的转化是通过大鼠肝微粒体氧化酶介导的,而不是通过酯酶。
3. 基于形成了dithiopyr-谷胱甘肽结合物,认为单酸形成机制是通过甲基硫酯组的初始硫氧化和随后的亲核取代反应进行的。
1. Transformation of dithiopyr by rat liver enzymes in vitro produced the corresponding monoacids as the predominant metabolites. 2. Transformations of the methylthioester functional groups in dithiopyr to the monoacids were mediated via rat liver microsomal oxygenases, and not via esterases. 3. Based on the formation of a dithiopyr-glutathione conjugate, the mechanism of monoacid formation is believed to proceed through an initial sulfur oxidation of the methylthioester group and a subsequent nucleophilic displacement reaction.
