The role of human cytochrome P450 2E1 in liver inflammation and fibrosis. [PDF]

open access: yes, 2017
Cytochrome P450 2E1 (CYP2E1) plays an important role in alcohol and toxin metabolism by catalyzing the conversion of substrates into more polar metabolites and producing reactive oxygen species.

Selection of Suitable Prodrug Candidates for in vivo Studies via in vitro Studies; The Correlation of Prodrug Stability in Between Cell Culture Homogenates and Human Tissue Homogenates

open access: yesJournal of Pharmacy & Pharmaceutical Sciences, 2012
Purpose. To determine the correlations/discrepancies of drug stabilities between in the homogenates of human culture cells and of human tissues. Methods. Amino acid/dipeptide monoester prodrugs of floxuridine were chosen as the model drugs.

Cloning of a human liver microsomal UDP-glucuronosyltransferase cDNA [PDF]

open access: yesBiochemical Journal, 1987
A cDNA clone (HLUG 25) encoding the complete sequence of a human liver UDP-glucuronosyltransferase was isolated from a lambda gt11 human liver cDNA library. The library was screened by hybridization to a partial-length human UDP-glucuronosyltransferase cDNA (pHUDPGT1) identified from a human liver pEX cDNA expression library by using anti-UDP ...

Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

open access: yesAnimal Research and One Health, EarlyView.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

Biotransformation of 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine (TTBP-TAZ) can contribute to high levels of 2,4,6-tribromophenol (2,4,6-TBP) in humans

open access: yesEnvironment International, 2022
2,4,6-Tribromophenol (2,4,6-TBP) is a brominated flame retardant that accumulates in human tissues and is a potential toxicant. Previous studies found 2,4,6-TBP levels in human tissues were significantly higher than those of brominated flame retardants ...

Identification of the metabolites of ivermectin in humans

open access: yesPharmacology Research & Perspectives, 2021
Mass drug administration of ivermectin has been proposed as a possible malaria elimination tool. Ivermectin exhibits a mosquito‐lethal effect well beyond its biological half‐life, suggesting the presence of active slowly eliminated metabolites.

Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality

open access: yesChemistry – A European Journal, EarlyView.
Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable
