Estradiol 3-(beta-D-Glucuronide) (sodium salt)

Estradiol 3-(beta-D-glucuronide) (E23G) is a non-cholestatic regioisomer of the estrogen metabolite, estradiol 17-(beta-D-glucuronide) (E217G, Cay-16156). It acts as a substrate for multidrug resistance protein 2 (MRP2, Km = 122 µM), competing with E217G for MRP2-mediated transport (IC50 = 14.2 µM). E23G has been reported to inhibit E217G transport through rat organic anion-transporting polypeptide 1 with a Ki value of 9.7 µM, but is a low-affinity inhibitor of both MRP4 and MRP7 (IC50s = ~ 100 µM).Formal Name: (17beta)-17-hydroxyestra-1,3,5(10)-trien-3-yl beta-D-glucopyranosiduronic acid, monosodium salt. CAS Number: 14982-12-8. Synonyms: E23G, beta-Estradiol 3-(beta-D-Glucuronide), 17beta-Estradiol 3-(beta-D-Glucuronide), 17beta-Oestradiol 3-(beta-D-Glucuronide). Molecular Formula: C24H31O8 . Na.
