Nebicapone is a reversible catechol-O-methyltransferase (COMT) inhibitor and is mainly metabolized by glucuronidation. Nebicapone is mainly peripherally acting inhibitor that decreases the biotransformation of L-DOPA to 3-O-methyl-DOPA by inhibition of CO
(-)-Sitagliptin carbamoyl glucuronide is a minor phase II metabolite of the dipeptidyl peptidase 4 (DPP-4) inhibitor (-)-sitagliptin . (-)-Sitagliptin carbamoyl glucuronide is formed by N-carbamoyl glucuronidation and has been found in rat and dog plasma following administration of (-)-sitagliptin.
Febuxostat acyl glucuronide is a metabolite of the xanthine oxidoreductase inhibitor febuxostat . Febuxostat acyl glucuronide is formed via glucuronidation of febuxostat by uridine diphosphate-glucuronosyltransferases (UGTs).
4’-hydroxy Atomoxetine glucuronide is a metabolite of the norepinephrine transporter (NET) inhibitor atomoxetine .1It is formed from atomoxetine by glucuronidation of the intermediate metabolite 4-hydroxy atomoxetine.2 1.Todor, I., Popa, A., Neag, M., et al.Evaluation of a potential metabolism-mediated drug-drug interaction between atomoxetine and bupropion in healthy volunteersJ.

(R,S)-Carvedilol glucuronide is a racemic mixture of the carvedilol metabolites (R)-carvedilol glucuronide and (S)-carvedilol glucuronide. (R)-Carvedilol glucuronide is formed via glucuronidation of (R)-carvedilol by the UDP-glucuronosyltransferase (UGT) isoforms UGT1A1 and UGT2B4. (S)-Carvedilol glucuronide is formed via glucuronidation of (S)-carvedilol by UGT2B4 and UGT2B7.
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.

Chlorzoxazone N-glucuronide is a phase II metabolite of the skeletal muscle relaxant chlorzoxazone . Chlorzoxazone N-glucuronide is formed via glucuronidation of chlorzoxazone by the UDP-glucuronosyltransferase (UGT) isoform UGT1A9.
CN128, an orally bioavailable iron chelator, features a side chain hydroxy group serving as an alternate sacrificial glucuronidation site to mitigate metabolic inactivation at the 3-hydroxy group. When administered at doses of 150 and 450 µmol kg, CN128 enhances iron mobilization by 24.8% in a 59Fe-ferritin-loaded rat model of iron overload.
