代谢
代谢通过侧链的氧化缩短以及醌环的还原和与葡萄糖醛酸和硫酸盐的结合来实现。艾地苯醌显示出高首次通过代谢,产生艾地苯醌的结合物(葡萄糖醛酸和硫酸盐(IDE-C))以及第一阶段代谢物QS10、QS6和QS4,以及它们相应的第二阶段代谢物(葡萄糖醛酸和硫酸盐(QS10+QS10-C, QS6+QS6-C, QS4+QS4-C))。血浆中的主要代谢物是IDE-C和QS4+QS4-C。
Metabolism occurs by means of oxidative shortening of the side chain and by reduction of the quinone ring and conjugation to glucuronides and sulphates. Idebenone shows a high first pass metabolism resulting in conjugates of idebenone (glucuronides and sulphates (IDE-C)) and the Phase I metabolites QS10, QS6, and QS4 as well as their corresponding Phase II metabolites (glucuronides and sulphates (QS10+QS10-C, QS6+QS6-C, QS4+QS4-C)). The main metabolites in plasma are IDE-C and QS4+QS4-C.
