代谢
Perospirone在肝脏经历快速而广泛的首过代谢;代谢途径涉及羟基化、N-脱烷基化和S-氧化,这些过程由CYP1A1、2C8、2D6和3A4催化。据报道,CYP3A4在perospirone代谢中的贡献水平最高。羟基化Perospirone是由环己烷-1,2-二羧亚胺部分羟基化形成的,并通过介导抗血清素能效应保留药理作用,尽管亲和力较低。
Perospirone undergoes rapid and extensive first-pass metabolism in the liver; the metabolic pathways involve hydroxylation, N-dealkylation, and S-oxidation, which are catalyzed by CYP1A1, 2C8, 2D6, and 3A4. CYP3A4 is reported to have highest level of contribution in perospirone metabolism. Hydroxyperospirone is formed from hydroxylation of the the cyclohexane-1,2-dicarboximide moiety and retains pharmacological action by mediating antiserotonergic effects, although with lower affinity.
