Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 127-17-3, Name is 2-Oxopropanoic acid, molecular formula is C3H4O3, belongs to Benzisoxazole compound. In a document, author is Nakasa, H, introduce the new discover, Quality Control of 2-Oxopropanoic acid.
Formation of 2-sulphamoylacetylphenol from zonisamide under aerobic conditions in rat liver microsomes
1. The antiepileptic agent zonisamide, 1,2-benzisoxazole-3-methanesulphonamide, was metabolized reductively to 2-sulphamoyl-acetylphenol (SMAP) not only under anaerobic conditions but also under aerobic conditions in liver microsomes of rat pretreated with phenobarbital or dexamethasone. 2. NADPH was required for the formation of SMAP from zonisamide under aerobic conditions. In addition, the reductive metabolism of zonisamide under these conditions was substantially inhibited by carbon monoxide, ketoconazole, and cimetidine, known inhibitors of cytochrome P450. 3. The formation of SMAP under aerobic conditions in liver microsomes was increased by pretreatment of rat with triacetyloleandomycin (TAO) and was increased by the treatment of the microsomes with ferricyanide. 4. These results imply that zonisamide is metabolized reductively to SMAP by a cytochrome P450 belonging to the 3A subfamily under aerobic conditions as well as anaerobic conditions.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 127-17-3. Quality Control of 2-Oxopropanoic acid.
