Application

β-Estradiol 3-(β-D-glucuronide) sodium salt has been used in estrogen administration. It has also been used to determine the amount of two types of glucuronidated estradiols such as estradiol-3- α glucuronide and estradiol-17- β glucuronide.

Traditionally, the Michaelis-Menten equation has been used to determine kinetic parameters for in vitro glucuronidation assays. Recently, estradiol-3-glucuronide formation was shown to exhibit non-Michaelis-Menten kinetics consistent with autoactivation. A concern with the observation of nontraditional kinetics is that they may

The glucuronidation of [3H]estradiol-17 beta at the C3 vs. the C17 hydroxyl groups was determined in female Sprague-Dawley rat liver microsomes. A high-performance liquid chromatography method was developed to resolve the glucuronide conjugates which were then quantitated by liquid scintillation

Commonly used herbal supplements were screened for their potential to inhibit UGT1A1 activity using human liver microsomes. Extracts screened included ginseng, echinacea, black cohosh, milk thistle, garlic, valerian, saw palmetto, and green tea epigallocatechin gallate (EGCG). Estradiol-3-O-glucuronide (E-3-G) formation was

We have previously found that repeated exposure to heroin reduces liver synthesis of morphine-3-glucuronide (M3G) and increases the production of morphine-6-glucuronide (M6G), which normally is not formed in the rat. By contrast repeated exposure to naltrexone does not activate M6G

beta-estradiol 17-(beta-D-glucuronide) (E217G) is a well known cholestatic agent and substrate of multidrug resistance-associated protein 2 (Mrp2), whereas beta-estradiol 3-(beta-D-glucuronide) (E23G) is a noncholestatic regioisomer of E217G with unknown transport properties. The purpose of this study was to compare and
