Synthesis of cortol 3-glucuronides and cortolone 3-glucuronides.

Chemical and Pharmaceutical Bulletin, 1984
The synthesis of the 3-glucuronides of 20α-cortolone and their 20β-epimers is described. The cortol 20, 21-diacetates (3, 10) and cortolone 20, 21-diacetates (6, 12) were the key intermediates. Sodium borohydride reduction of the carbonyl group at C-20 in 21-acetoxy-3α, 11β, 17α-trihydroxy-5β-pregnan-20-one 3-tert-butyldimethylsilyl ether (1) or its 11-

The Effect of Uridine Diphosphate‐Glucuronosyltransferase Inhibition on the Pharmacokinetics of Ecopipam and Its Metabolites

Clinical and Translational Science
Ecopipam, a selective dopamine D1 receptor antagonist in development for Tourette syndrome, is primarily converted by uridine diphosphate‐glucuronosyltransferase (UGT)1A9 to ecopipam glucuronide, with a minor metabolic pathway by cytochrome P450 3A4 ...

Isoursodeoxycholic acid: metabolism and therapeutic effects in primary biliary cirrhosis1

Journal of Lipid Research, 2001
Significant amounts of ursodeoxycholic acid (UDCA) used for the treatment of patients with primary biliary cirrhosis (PBC) become epimerized at C-3 to isoUDCA. We investigated the metabolism of isoUDCA and a possible pharmacologic effect in five patients

Characterization of Phase I and Glucuronide Phase II Metabolites of 17 Mycotoxins Using Liquid Chromatography—High-Resolution Mass Spectrometry

Toxins, 2019
Routine mycotoxin biomonitoring methods do not include many mycotoxin phase I and phase II metabolites, which may significantly underestimate mycotoxin exposure especially for heavily metabolized mycotoxins. Additional research efforts are also needed to

Liver Transplantation Outcomes in Crigler‐Najjar Syndrome in Iran: A Single‐Center Retrospective Cohort Study Over 20 Years

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Crigler‐Najjar Syndrome (CNS) is a rare autosomal recessive disorder caused by uridine diphosphate glucuronosyltransferase (UGT1A1) deficiency, leading to unconjugated hyperbilirubinemia. Without treatment, patients are at high risk of kernicterus and irreversible neurological damage.

In Vitro and Clinical Evaluation of Potential Interactions of Bemnifosbuvir with Drug‐Metabolizing Enzymes

The Journal of Clinical Pharmacology, Volume 66, Issue 5, May 2026.
Abstract Bemnifosbuvir is a novel oral guanosine nucleotide prodrug with potent pan‐genotypic inhibitory activity against hepatitis C virus. In vitro studies assessing the inhibition or induction potential of bemnifosbuvir on the CYP450 and UGT1A1 enzymes demonstrated that bemnifosbuvir is a weak inducer and a reversible and time‐dependent inhibitor of
