The cyclic ammonium cation 5 and its guanidinium analogue 4 are inhibitors of tocopherol cyclase. Monoclonal antibodies were raised against protein conjugates of the haptens 1-3 and screened for catalytic reactions with alkene 8, a short chain analogue of the natural substrate phytyl-hydroquinone 6, and its enol ether analogues 10a,b. Antibody 16E7 raised against hapten 3 was found to catalyze the hydrolysis of Z enol ether 10a to form hemiacetal 12 with an apparent rate acceleration of k(cat)/k(uncat) = 1400. Antibody 16E7 also catalyzed the elimination of Kemp’s benzisoxazole 59. The absence of cyclization in the reaction of enol ether 10a was attributed to the competition of water molecules for the oxocarbonium cation intermediate within the antibody binding pocket. Hapten and reaction design features contributing to this outcome are discussed. Antibody 16E7 provides the first example of a carboxyl group acting both as an acid in an intrinsically acid-catalyzed process and as a base in an intrinsically base-catalyzed process, as expected from first principles. In contrast to the many examples of general-acid-catalyzed processes known to be catalyzed by catalytic antibodies, the specific-acid-catalyzed cyclization of phytyl-hydroquinone 6 or its analogue 8 still eludes antibody catalysis.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 123-76-2 is helpful to your research. Formula: https://www.ambeed.com/products/123-76-2.html.

A tailor-made catalytically active polymer catalyzing the benzisoxazole isomerization is described. Kinetic studies carried out in water/ethanol (3:1, v/v) at room temperature, showed a rate acceleration (k(MIP)/k(control)) of 7.2-fold compared to the control polymer. The imprinted polymer exhibits Michaelis-Menten kinetics with a K-m of 0.484 mM and a k(cat) of 0.205 min(-1). Compared with the uncatalyzed reaction, a rate enhancement ((k(cat)/K-m)/k(uncat)) of 4 x 10(4) fold was obtained. Substrate selectivity, accessible binding site analysis, dissociation constant determination, and inhibition study were also performed.

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.

3-Ethyl ester- (1) and 3-carboxylic acid-isoxazole (2) derivatives of an antiviral drug analogue WIN 61893 were synthesized and characterized by X-ray crystallography and NMR spectroscopy. Crystallization experiments afforded two polymorphic structures for the ethyl ester derivative and two solvate structures for the carboxylic acid derivative based on their ability to form intermolecular hydrogen bonding interactions with the solvent molecules. The conformations of the derivatives depended greatly on the orientation of the planar isoxazole and phenyl-oxadiazole ring systems with respect to one another and were found to take up perpendicular, linear or tilted conformations. The carboxylic acid derivative was furthermore observed to undergo isoxazole ring cleavage by decarboxylation in DMSO solution and transforming into a beta-keto nitrile ring-opening product over several days, whereas, the isoxazole ring of the ethyl ester derivative was not affected.

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.

Zonisamide is increasingly used in pediatric neurology but there are no experimental data for immature animals. Zonisamide (12.5-100 mg/kg i.p.) was tested against pentetrazol-induced seizures in 7-, 12-, 18-, 25- and 90-day-old rats. Minimal clonic seizures were not suppressed by zonisamide. Selective suppression of tonic phase of generalized tonic-clonic seizures was demonstrated in all age groups. This effect indicates possible action of zonisamide against generalized tonic-clonic seizures during brain maturation. (C) 2010 Published by Elsevier B.V.

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.
