The goal of this study was to provide a reasonable assessment of how probe substrate selection may impact the results of in vitro aldehyde oxidase (AO) inhibition experiments. Here, we used a previously studied set of seven known AO inhibitors to probe the inhibition profile of a pharmacologically relevant substrate N-[(2-dimethylamino)ethyl]acridine-4-carboxamide (DACA). DACA oxidation in huma...

The catalytic oxidation of catechol by crude preparations of mushroom tyrosinase was studied by a method yielding data on initial reaction velocities. Graphical analysis of the results suggests that an excess of catechol inhibits its own oxidation by a competitive process, thus accounting for the observed optimum in the substrate concentration. However, added phenol, though itself a substrate, ...

Drug-drug interactions may cause serious adverse events in the clinical setting, and the cytochromes P450 are the enzyme system most often implicated in these interactions. Cytochrome P450 2C is the second most abundant subfamily of cytochrome P450 enzymes and is responsible for metabolism of almost 20% of currently marketed drugs. The most abundant isoform of this subfamily is CYP2C9, which is...

UDP-Glucuronosyltransferases (UGTs) are a class of enzymes (please refer to Mackenzie et al. [1] for UGT nomenclature and classification) anchored in the membrane of endoplasmic reticulum. The UGT enzyme catalyzes glucuronidation, a major metabolic pathway in humans, by transferring a glucuronic acid from the cofactor UDPglucuronic acid to the substrate. In vitro characterization has revealed t...
