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

open access: yesClinical 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 ...

In Vitro and In Vivo Analysis of Ochratoxin A-Derived Glucuronides and Mercapturic Acids as Biomarkers of Exposure

open access: yesToxins, 2021
Ochratoxin A (OTA) is a widespread food contaminant, with exposure estimated to range from 0.64 to 17.79 ng/kg body weight (bw) for average consumers and from 2.40 to 51.69 ng/kg bw per day for high consumers.

Association of NQO2 With UDP-Glucuronosyltransferases Reduces Menadione Toxicity in Neuroblastoma Cells

open access: yesFrontiers in Pharmacology, 2021
The balance between detoxification and toxicity is linked to enzymes of the drug metabolism Phase I (cytochrome P450 or oxidoreductases) and phase II conjugating enzymes (such as the UGTs).

Conjugated Metabolites of Hydroxytyrosol and Tyrosol Contribute to the Maintenance of Nitric Oxide Balance in Human Aortic Endothelial Cells at Physiologically Relevant Concentrations

open access: yesMolecules, 2021
Nitric oxide (NO) is an important signaling molecule involved in many pathophysiological processes. NO mediates vasodilation and blood flow in the arteries, and its action contributes to maintaining vascular homeostasis by inhibiting vascular smooth ...

Synthetic Artificial Apoptosis‐Inducing Receptor for On‐Demand Deactivation of Engineered Cells

open access: yesAdvanced Science, 2021
The design of a fully synthetic, chemical “apoptosis‐inducing receptor” (AIR) molecule is reported that is anchored into the lipid bilayer of cells, is activated by the incoming biological input, and responds with the release of a secondary messenger—a ...

Enzymatic Synthesis of α-Glucosyl-Baicalin through Transglucosylation via Cyclodextrin Glucanotransferase in Water

open access: yesMolecules, 2023
Baicalin is a biologically active flavone glucuronide with poor water solubility that can be enhanced via glucosylation. In this study, the transglucosylation of baicalin was successfully achieved with CGTases from Thermoanaerobacter sp.

Ethyl glucuronide [PDF]

open access: yesAnnals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2012
Alcohol is associated with significant morbidity and mortality. Subjects abusing alcohol can be identified through clinical history, examination or self-report questionnaires. A range of biomarkers is available for detecting alcohol misuse, but there is still a need for a marker that can detect alcohol consumption in the time window between one day ...

Contributions of UDP-Glucuronosyltransferases to Human Hepatic and Intestinal Metabolism of Ticagrelor and Inhibition of UGTs and Cytochrome P450 Enzymes by Ticagrelor and its Glucuronidated Metabolite

open access: yesFrontiers in Pharmacology, 2021
Ticagrelor is the first reversibly binding, direct-acting, oral P2Y12 receptor inhibitor. The contribution of UDP-glucuronosyltransferases (UGTs) enzymes to the metabolism of ticagrelor to its glucuronide conjugation, ticagrelor-O-glucuronide, in human ...
