In this paper, a monolithic ODS-silica gel column dynamically coated with cetylpyridinium chloride (CPC) was used to demonstrate the high-speed and efficient separation of zonisamide (1,2-benzisoxazole-3-methanesulfonamide, ZNS). its raw material (1,2-benzisoxazole-3-methanecarbonic acid) and intermediate (sodium 1,2-benzisoxazole-3-methanesulfonate) in drugs. Using a 40 mmol/L sodium perchlorate solution (pH 7.0) containing 10% acetonitrile as eluent, the analytes were eluted with a sharp and symmetrical peak within 3.0 min, detected with UV detection at 210 nm. The column demonstrates excellent stability over time, and exhibits unusual selectivity for pharmaceutical analysis. Thus, by this developed method, zonisamide in drug samples can be determined rapidly with high recoveries and good selectivity. (c) 2006 Elsevier B.V. All rights reserved.

Decarboxylation of 6-nitrobenzisoxazole-3-carboxylate in polyampholyte latexes

Polyampholyte latexes that contain 29/18 and 25/23 mol % of (styrylmethyl)trimethylammonium/methacrylate units and styrene cross-linked with divinylbenzene are colloidally stable in 4 M NaCl solution. As catalytic media in basic solutions 0.5 mg mL(-1) of the polyampholyte latexes increase the rate of decarboxylation of 6-nitrobenzisoxazole-3-carboxylate (6-NBIC) 60-115 times, while the precursor polycation latexes increase the rate 540-670 times the rate in water alone. The latexes are active catalysts in 0.67 M NaCl solution, but activity decreases as the concentration of added NaCl increases. Analysis of rate constants at varied particle concentrations indicates that the fractions of the 6-NBIC anions bound to particles are similar in the two types of latexes and that the differences in activity are due primarily to larger intraparticle rate constants in the polycation latexes than in the polyampholytes.

Iloperidone: a new benzisoxazole atypical antipsychotic drug. Is it novel enough to impact the crowded atypical antipsychotic market?

Iloperidone is a new-generation atypical antipsychotic agent, acting as a serotonin/dopamine (5-HT2A/D-2) antagonist, under development by Vanda Pharmaceuticals for the treatment of schizophrenia, bipolar disorder and other psychiatric conditions. Chemically, iloperidone is a benzisoxazole, like risperidone, and shows a multiple receptor binding profile, sharing this feature with the other atypical antipsychotic agents. Administered orally, the drug is highly bound to plasma proteins and extensively metabolised. Several clinical trials have been carried out, to check efficacy, safety and side effects. in order to introduce iloperidone as an agent for the treatment of schizophrenia, a short overview of the disease and of the most important antipsychotic drugs available or under development will be reported. Iloperidone pharmacokinetics and pharmacodynamics are presented herein, together with an evaluation of clinical safety and efficacy results.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 68-04-2, you can contact me at any time and look forward to more communication. SDS of cas: 68-04-2.

STUDIES ON URICOSURIC DIURETICS .2. SUBSTITUTED 7,8-DIHYDROFURO[2,3-G]-1,2-BENZISOXAZOLE-7-CARBOXYLIC ACIDS AND 7,8-DIHYDROFURO[2,3-G]BENZOXAZOLE-7-CARBOXYLIC ACIDS

A series of substituted 7,8-dihydrofuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acids 9 and 7,8-dihydrofuro[2,3-g]benzoxazole-7-carboxylic acids 12 were synthesized and evaluated for uricosuric and diuretic activities in rats. Many of the benzisoxazole derivatives 9 showed uricosuric and only weak diuretic activities, whereas the benzoxazoles 12 exhibited potent diuretic activities with little affecting urate excretion. Among these compounds, 5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid (9b, AA-193) was found to be a potent uricosuric agent without diuretic activity and was selected for further development.

Are Heme-Dependent Enzymes Always Using a Redox Mechanism? A Theoretical Study of the Kemp Elimination Catalyzed by a Promiscuous Aldoxime Dehydratase

The design of biocatalysts is a goal to improve the rate, selectivity, and environmental friendliness of chemical processes in biotechnology. In this regard, the use of computational techniques has provided valuable assistance in the design of enzymes with remarkable catalytic activity. In this paper, hybrid QM/MM simulations have allowed getting an insight into the mechanism of a promiscuous aldoxime dehydratase (OxdA) for Kemp elimination. We first demonstrate that, based on the use of linear response approximation (LRA) methods, the lowest energy electronic state of the benzisoxazole placed in the active site of OxdA corresponds to a singlet state, the triplet and the quintet states being higher in energy. The presence of a heme group at the active site of the OxdA promiscuous enzyme opens the possibility of exploring a redox mechanism, similar to the one proposed in other reactions catalyzed by heme-dependent enzymes. In addition, according to the geometrical analysis of the active site of this aldoxime dehydratase, the presence of a good base in the active site, His320, the proper pose of the substrate assisted by the porphyrin, and an adequate electrostatic environment to stabilize the negative charge developed in the oxygen-leaving group makes available an acid/base mechanism. Comparison of the results derived from the exploration of both acid/base and redox mechanisms at the B3LYP(Def2-TZVP)/MM level shows how the latter renders the most favorable reaction path within the quintet state. The obtained activation free energy is in good agreement with the activation energy that can be deduced from the experimentally measured rate constant.

Is subnanomolar binding affinity required for the in vivo imaging of acetylcholinesterase? Studies on F-18-labeled G379

Acetylcholinesterase (AChE) is an important cholinergic marker of Alzheimer’s disease (AD) and shows reduced activity in postmortem AD brain tissues. 1-(4-Fluorobenzyl)-4-[(5,6-dimethoxy-l-oxoindan-2-fluoro-2-yl)methyl]piperidine (G379, 1), an AChE inhibitor with a subnanomolar IC50 (0.56 nM), was prepared as a F-18-labeled radioligand ([F-18]1) and evaluated in mice. Metabolism studies of [F-18]1 showed no metabolites in the mouse brain. Tissue distribution studies demonstrated its uniform regional distribution in the mouse brain, suggesting that this radioligand is not suitable for the in vivo imaging of AChE. This result along with reports on radiolabeled AT-benzylpiperidine lactam benzisoxazole (IC50 < 1 nM) and other radiolabeled benzylpiperidme derivatives (IC50 > 1 nM) suggested that a subnanornolar IC50 may not be the only important factor in determining the suitability of a radioligand for in Vivo Studies of AChE.

The cleavage of 1-amino-2′-nitrobenzylphosphonates in a basic medium. Formation of the 3-amino-2,1-benzisoxazole derivatives

Treatment of 1-amino-2′-nitrobenzylphosphonic acids with aqueous sodium hydroxide caused a C-P bond cleavage, with formation of 3-amino-2,1-benzisoxazole derivatives (3). The leaving phosphorus moiety was identified here as phosphoric acid. In the case of basic hydrolysis of corresponding esters, new cyclic phosphorus compounds (derivatives of benzoxazaphosphorin-3,1,2 P-V-one-2) were obtained. The cyclic products were formed as a result of the subsequent reaction of anthranil derivatives with leaving phosphorus fragment, presumably metaphosphate. These benzoxazaphosphorins (compounds 4) were converted by means of aqueous hydrochloric acid to 3-amino-2,1-benzisoxazole derivatives. (C) 1997 Elsevier Science Ltd.
