代谢
主要代谢途径是葡萄糖醛酸化,其中UGT1A1贡献了高达61%的binimetinib代谢。Binimetinib的其他代谢途径包括N-脱烷基化、酰胺水解以及侧链乙烷二醇的丢失。由CYP1A2和CYP2C19产生的活性代谢物M3代表了8.6%的binimetinib暴露。在单次口服45毫克放射性标记的binimetinib后,循环中约60%的放射性活性AUC在血浆中归因于binimetinib。
The primary metabolic pathway is glucuronidation with UGT1A1 contributing up to 61% of the binimetinib metabolism. Other pathways of binimetinib metabolism include N-dealkylation, amide hydrolysis, and loss of ethane-diol from the side chain. The active metabolite M3 produced by CYP1A2 and CYP2C19 represents 8.6% of the binimetinib exposure. Following a single oral dose of 45 mg radiolabeled binimetinib, approximately 60% of the circulating radioactivity AUC in plasma was attributable to binimetinib.
