产品介绍
Raloxifene 4'-glucuronide 是 Raloxifene 的主要代谢产物。Raloxifene 4'-glucuronide 的形成主要由 UGT1A10 和 UGT1A8 介导,以IC50为 370 μM 与estrogen receptor结合。Raloxifene 是选择性雌激素受体调节剂。 Raloxifene 在纳摩尔浓度激活 TGFβ3 启动子为完全激动剂,并抑制含雌激素反应元件的卵黄蛋白原启动子的表达。
生物活性

Raloxifene 4'-glucuronide is a primary metabolite of Raloxifene. Raloxifene 4'-glucuronide formation is mediated mostly by UGT1A10 and UGT1A8. Raloxifene 4'-glucuronide binds toestrogen receptorwith anIC50of 370 μM.[1][2]. Raloxifene is a selectiveestrogen receptormodulator. Raloxifene activates TGFβ3 promoter as a full agonist at nanomolar concentrations, and inhibits the estrogen response element-containing vitellogenin promoter expression[3].

IC50& Target

IC50: 370 μM (Estrogen receptor)[2]

体外研究
(In Vitro)

Expressed UGT1A8 catalyzes Raloxifene 4'-glucuronide with an apparent Kmof 59 μM and a Vmaxof 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[2].
