Estrone-3-Glucuronide is a metabolite of the primary premenopausal estrogen 17β-estradiol .1,2Urinary levels of estrone-3-Glucuronide peak approximately 36 hours prior to ovulation and have been used as a marker of fertility in women. 1.Blackwell, L.F., Brown, J.B., and Cooke, D.Definition of the potentially fertile period from urinary steroid excretion rates.

Estriol 3-β-D-glucuronide is a metabolite of estriol . It is formed from estriol by the UDP-glucuronosyltransferase (UGT) isoform UGT1A10. Estriol 3-β-D-glucuronide binds to basolateral and canalicular liver plasma membranes with Kd values of 85 and 164 μM, respectively. It competitively inhibits the hydrolysis of 4-methylumbelliferyl-β-D-glucuronide and is a substrate for hydrolysis by Klotho-human IgG1 Fc protein (KLFc).
Dapagliflozin-3-O-β-D-glucuronide is a metabolite of dapagliflozin . Dapagliflozin is a first generation selective sodium glucose cotransporter (SGLT) 2 inhibitor that blocks glucose transport.[1] Dapagliflozin is metabolized by uridine diphosphate glucuronosyltransferase (UGT) 1A9 to dapagliflozin-3-O-β-D-glucuronide, which is 2,600-fold less potent than the parent compound with regard to SGLT2 inhibition.[2]
Ethynyl estradiol 3-β-D-glucuronide is a metabolite of ethynyl estradiol that can be detected in urine.1,2It is used as a marker of estrogen contamination in fresh and saltwater.2 1.Hadd, H.E., Slikker, W., Jr., and Helton, E.D.The synthesis and characterization of the glucopyranosiduronic acids of 17a-ethynylestradiol-17bJ.
