In a document, author is Sugihara, K, introducing its new discovery. Category: Benzisoxazole.

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide) an anticonvulsant agent, is primarily metabolized to 2-sulfamoylacetyl-phenol by reductive cleavage of the 1,2-benzisoxazole ring. Rabbit liver cytosol with an electron donor of aldehyde oxidase exhibited a significant zonisamide reductase activity that was sensitive to inhibition by menadione, an inhibitor of aldehyde oxidase, The result suggested that the cytosolic activity is caused by aldehyde oxidase, a cytosolic enzyme. In fact, rabbit and rat liver aldehyde oxidase had the ability to reduce zonisamide when supplemented with its electron donor, Apparent K-M and V-max values of aldehyde oxidase for zonisamide were 217 mu M and 42 nmol/10 min/mg protein in the case of the rabbit liver enzyme, and 542 mu M and 382 nmol/10 min/mg protein in the case of the rat liver enzyme, respectively. In rabbits, hamsters, mice, and guinea pigs, zonisamide reductase activity of the liver cytosols with 2-hydroxypyrimidine, an electron donor of aldehyde oxidase, was much higher than that of the liver microsomes with NADPH. In rats, zonisamide reductase activity was examined with liver microsomes and cytosols from seven strains. The 2-hydroxypyrimidine-dependent cytosolic activity exhibited marked strain differences, unlike the NADPH-dependent microsomal activity, 1,2-Benzisoxazole was also reduced to salicylaldehyde by rabbit liver cytosol and aldehyde oxidase in the presence of 2-hydroxypyrimidine, Stoichiometric studies showed that 2-sulfamoylacetylphenol was formed accompanying nearly equimolar ammonia from zonisamide.

Zirconocene alkyne complexes Cp(2)Zr(L)(Me(3)SiC(2)R) (L = Py, THF; R = SiMe(3), tBu) react with heterocyclic compounds like benzoxazole and related thiazoles to yield ring-expanded adducts Cp(2)Zr-C(SiMe(3))=C(R)-CH=N-o-C6H4-X (1-3) and Cp(2)Zr-C(SiMe(3))=C(SiMe(3))-CH=N-C(R’)=C(R’)-X (R’ = Me, H) (4, 5) by formal C-X (X = O, S) bond cleavage and coupling with the coordinated alkyne. In the case of benzisoxazole, the alkyne is not coupled but eliminated, and with ring-enlargement of the benzisoxazole a N-bridged dimer [Cp(2)Zr-N=CH-o-C6H4-O](2) (6) is formed. The obtained complexes 1, 3, and 6 were characterized by NMR spectra and crystal structure analysis.

The Kemp elimination reaction is a well-known chemical reaction that is facilitated on a protein surface microenvironment, and in particular is highly accelerated in a unique binding pocket of serum albumin. We have designed and synthesized a fluorescently activatable coumarin derivative with a benzisoxazole scaffold to enable monitoring of the Kemp elimination reaction in terms of fluorescence change for the first time. We show that this fluorescent sensor can sensitively and selectively quantitate serum albumin in blood samples. It also works in a dry-chemistry format. (C) 2017 Elsevier Ltd. All rights reserved.

Formula: https://www.ambeed.com/products/619-05-6.html, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction. 619-05-6, Name is 3,4-Diaminobenzoic acid, molecular formula is C7H8N2O2.

The emergence of multi-drug resistant pathogenic bacteria represents a serious and growing threat to national healthcare systems. Most pressing is an immediate need for the development of novel antibacterial agents to treat Gram-negative multi-drug resistant infections, including the opportunistic, hospital-derived pathogen, Acinetobacter baumannii. Herein we report a naturally occurring 1,2-benzisoxazole with minimum inhibitory concentrations as low as 6.25 mu g ml(-1) against clinical strains of multi-drug resistant A. baumannii and investigate its possible mechanisms of action. This molecule represents a new chemotype for antibacterial agents against A. baumannii and is easily accessed in two steps via de novo synthesis. In vitro testing of structural analogs suggest that the natural compound may already be optimized for activity against this pathogen. Our results demonstrate that supplementation of 4-hydroxybenzoate in minimal media was able to reverse 1,2-benzisoxazole’s antibacterial effects in A. baumannii. A search of metabolic pathways involving 4-hydroxybenzoate coupled with molecular modeling studies implicates two enzymes, chorismate pyruvate-lyase and 4-hydroxybenzoate octaprenyltransferase, as promising leads for the target of 3,6-dihydroxy-1,2-benzisoxazole.
