產品描述：
Atorvastatin lactone-d5 is intended for use as an internal standard for the quantification of atorvastatin lactone by GC- or LC-MS. Atorvastatin lactone is an active metabolite of the HMG-CoA reductase inhibitor atorvastatin.1,2 It is formed from atorvastatin by the UDP-glucuronosyltransferase (UGT) isoforms UGT1A3 and UGT1A1 in insect cell-derived supersomes expressing the human enzymes, and hydrolyzes to form atorvastatin in human serum at room temperature.2,3 Atorvastatin lactone inhibits HMG-CoA reductase (IC50 = 0.007 μM for the rat liver enzyme).1 It also inhibits the cytochrome P450 (CYP) isoforms CYP2C9.1 and CYP2C9.3 (IC50s = 16.8 and 5.62 μM, respectively), as well as P-glycoprotein (P-gp; IC50 = 3.1-5.2 μM).4,5 1.Roth, B.D., Blankley, C.J., Chucholowski, A.W., et al.Inhibitors of cholesterol biosynthesis. 3.
