Dolutegravir O-β-D-glucuronide is a metabolite of the HIV integrase inhibitor dolutegravir .1It is formed from dolutegravir primarily by the UDP-glucuronosyltransferase (UGT) isoform UGT1A1in vivobut is also metabolized by UGT1A9 in human liver and kidney microsomes and UGT1A3 in human intestinal microsomes.2,1 1.Liu, S.N., Lu, J.B., Watson, C.J.W., et al.Mechanistic assessment of extrahepatic contributions to glucuronidation of integrase strand transfer inhibitorsDrug Metab.

Chenodeoxycholic acid 24-acyl-β-D-glucuronide (CDCA-24G), a metabolite of CDCA, is synthesized from CDCA via the action of the UDP-glucuronosyltransferase (UG UT) isoform UGT1A3.
Naringenin-7-O-β-D-glucuronide, a metabolite of the flavonoid naringenin, is predominantly synthesized through the action of UDP-glucuronosyltransferase (UGT) isoforms UGT1A1, UGT1A3, UGT1A6, and UGT1A9.
