by HPLC–MS/MS, revealed a major metabolite, where hydroxylation of MCC950 had occurred on the 1,2,3,5,6,7-hexahydro-s-indacene moiety. Three possible regioisomers were synthesized, and coelution using HPLC–MS/MS confirmed the structure of the metabolite. Further synthesis of individual enantiomers and coelution studies using a chiral column in HPLC–MS/MS showed the metabolite was R-(+)- N-((1-hydroxy-1
MCC950是口服的生物可利用的小分子抑制剂,可抑制包含NOD样受体的吡啶结构域的蛋白质3(NLRP3)炎性小体,在多种炎症性疾病模型中均表现出卓越的活性。与人肝微粒体,并通过HPLC-MS / MS随后的分析MCC950的温育后,揭示了主要代谢物,其中已对1,2,3,5,6,7-六氢发生MCC950的羟化小号-indacene部分。合成了三种可能的区域异构体,并使用HPLC-MS / MS进行共洗脱,确认了代谢物的结构。各个对映异构体的进一步合成和在HPLC-MS / MS中使用手性柱的共洗脱研究表明,代谢物为R -(+)- N -((1-羟基-1,2,3,5,6,7-六氢- s-indacen-4-基)氨基甲酰基)-4-(2-羟基丙-2-基)呋喃-2-磺酰胺(2a)。将MCC950与一组细胞色素P450酶一起孵育显示P450 2A6、2C9、2C18、2C19、2J2和3A4催化主要代谢产物2a的形成,而P450
