Raloxifene 4'-glucuronide-d4
Raloxifene 4'-glucuronide-d4 is deuterated labeled Raloxifene 4'-glucuronide (HY-135582). Raloxifene 4'-glucuronide is a primary metabolite of Raloxifene. Raloxifene 4'-glucuronide formation is mediated mostly by UGT1A10 and UGT1A8. Raloxifene 4'-glucuronide binds to estrogen receptor with an IC50 of 370 μM. . Raloxifene is a selective estrogen receptor modulator. Raloxifene activates TGFβ3 promoter as a full agonist at nanomolar concentrations, and inhibits the estrogen response element-containing vitellogenin promoter expression.

Biological Activity
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
Expressed UGT1A8 catalyzes Raloxifene 4'-glucuronide with an apparent Km of 59 μM and a Vmax of 2.0 nmol/min/mg. Based on rates of Raloxifene glucuronidation and known extrahepatic expression, UGT1A8 and 1A10 appear to be primary contributors to Raloxifene glucuronidation in human jejunum microsomes. For human liver microsomes, the variability of Raloxifene 4'-glucuronide formation is 4-fold. Treatment of expressed UGTs with alamethicin results in minor increases in enzyme activity, whereas in human intestinal microsomes, maximal increases of 9-fold for the Raloxifene 4'-glucuronide are observed. Intrinsic clearance values in intestinal microsomes are 95 μl/min/mg for the Raloxifene 4'-glucuronide[3].
