代谢
羧酸酯酶酶参与filgotinib的代谢。[A221331] 羧酸酯酶2(CES2)亚型主要负责将filgotinib代谢为其主要代谢物,GS-829845。[A221331,A221336] 尽管羧酸酯酶1(CES1)在filgotinib的生物转化中作用较小,但体外研究已经证明,在CES2饱和的情况下,CES1将部分补偿。[A221331] GS-829845是目前唯一被识别的主要循环代谢物。[L16616]
Carboxylesterase enzymes are involved in the metabolism of filgotinib.[A221331] The carboxylesterase 2 (CES2) isoform is chiefly responsible for metabolizing filgotinib to its major metabolite, GS-829845.[A221331,A221336] Although carboxylesterase 1 (CES1) plays a less prominent role in the biotransformation of filgotinib, in vitro studies have demonstrated that CES1 will partially compensate in the event of CES2 saturation.[A221331] GS-829845 is thus far the only major circulating metabolite to have been identified.[L16616]
