代谢
特拉左洛斯(Travoprost),一种异丙酯前药,通过角膜中的酯酶水解为其具有生物活性的自由酸。在全身循环中,特拉左洛斯自由酸在肾脏、肝脏和肺中通过β-氧化其α-(羧酸)链,迅速且广泛地代谢为不活跃的代谢物,生成1,2-二诺和1,2,3,4-四诺类似物,以及通过15-羟基团的氧化和13,14双键的还原。
Travoprost, an isopropyl ester prodrug, is hydrolyzed by esterases in the cornea to its biologically active free acid. Systemically, travoprost free acid is rapidly and extensively metabolized in the kidney, liver, and lung to inactive metabolites via beta-oxidation of the α(carboxylic acid) chain to give the 1,2-dinor and 1,2,3,4-tetranor analogs, via oxidation of the 15-hydroxyl moiety, as well as via reduction of the 13,14 double bond.
