A selective and sensitive liquid chromatographic method was developed for the determination of zonisamide in small volumes of plasma. Zonisamide and the internal standard methyl 4-hydroxybenzoate were extracted from 0.2 mL. of plasma with solid-phase extraction columns and eluted with methanol. Analysis of the extracts was performed on a Symmetry C-18 column with ultra-violet spectrophotometric detection. The calibration curve was linear over the concentration range of 0.05-5 mug mL(-1) in plasma. Recoveries were reasonable for routine analyses; the limit of quantification was 0.05 mug mL(-1) with a signal-to-noise ratio of 5. This method could be useful for the pharmacokinetic study of zonisamide in a limited volume of human plasma and for therapeutic drug monitoring.

Enzymes catalyze chemical reaction in aqueous media, but their active sites significantly differ in properties from water. In this chapter, the work on selected chemical reactions with important biological roles is reviewed to assess our current understanding of the effect of the environment that surrounds the reactive species. In particular, simple medium effects such as the ones provided by organic solvents, ionic liquids, and simple micelles are focused on. The findings that led to the computational design of enzymes that catalyze the Kemp elimination, a prototypical proton transfer reaction that has fascinated researchers for more than a century, are discussed.

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.

Electric Literature of 123-76-2, New Advances in Chemical Research, May 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 123-76-2, Name is 4-Oxopentanoic acid, SMILES is C(C(C)=O)CC(O)=O, belongs to benzisoxazole compound. In a article, author is Kozielewicz, Pawe, introduce new discover of the category.

DFT calculations have shown that the N-O dipole of benzene- and naphthalene-fused 1,2-oxazole N-oxides causes a distortion of their sigma and pi frame, concentrated on the 1,2-oxazole ring, such that it increases its susceptibility to opening. The distortion forces the benzene ring into some diene geometry, thus, reducing pi delocalization over the bi- or tricyclic structure and ultimately their aromatic character. C-3 substitution has a marked influence mainly on the naphthalene-fused N-oxides. C-5 and particularly C-6 substitution, as the position of most extended interaction with the N-O dipole through the pi ring density, contribute to the distortion of the 1,2-oxazole geometry and thereby to the decrease of aromaticity of the structure. Bond uniformity (I (A)), average bond order (ABO) and Harmonic Oscillator Model of Aromaticity (HOMA) indices have been recruited to measure aromaticity changes. I (A) and ABO appear to be more credible to 1,2-benzoxazole N-oxides and 1,2-naphthoxazole N-oxides, respectively, while HOMA has been found equally reliable to both. Hardness and dipole moments follow similar trends. Energies, localization and separation of the four frontiers orbitals, i.e. HO, HO-1, and LU, LU+1, indicate a rather notable aromatic character of the N-oxides. Their reactivity profile, portrayed by descriptors such as Fukui and electro(nucleo)philicity Parr functions, shows good agreement with experimental outcomes towards electrophiles but succumbs to discrepancies towards nucleophiles due to the susceptibility of the hetero-ring to opening. The push-pull character of the N-O dipole and more importantly the extent of its double bonding direct site selectivity.
