代谢
鞘氨醇激酶将芬戈利莫转化为活性代谢物,芬戈利莫磷酸盐。芬戈利莫的代谢通过3个主要代谢途径发生:首先,芬戈利莫磷酸盐的(S)-对映体的磷酸化(药理学上活性),其次,通过细胞色素P450 4F2(CYP4F2)的氧化,最后,通过脂肪酸样代谢转化为各种无活性代谢物。在代谢过程中,还会形成芬戈利莫的无活性非极性神经酰胺类似物。
Sphingosine kinase metabolizes fingolimod to an active metabolite, fingolimod phosphate. Fingolimod metabolism occurs via 3 major metabolic pathways: firstly, phosphorylation of the (S)-enantiomer of fingolimod-phosphate (pharmacologically active), secondly, oxidation by cytochrome P450 4F2 (CYP4F2), and thirdly, fatty acid-like metabolism to various inactive metabolites. The formation of inactive non-polar ceramide analogs of fingolimod also occurs during its metabolism.
