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.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 2836-32-0, Name is Sodium glycolate, SMILES is OCC([O-])=O.[Na+], belongs to benzisoxazole compound.

Several 1,2-benzisoxazole phosphorodiamidates have been designed as prodrugs of phosphoramide mustard requiring bioreductive activation. Enzymatic reduction of 1,2-benziosoxazole moiety is expected to result in the formation of imine intermediate due to the cleavage of the N-O bond. The imine should then be spontaneously hydrolyzed to a ketone metabolite, thereby facilitating base-catalyzed beta-elimination of cytotoxic phosphoramide mustard. As expected, the proposed prodrugs 4, 9, and 12 were at least 3-5-fold more potent cytotoxins than control compounds 5 and 15, which lack in the phosphoramide mustard group. Upon incubation with phenobarb-induced rat liver S-9 fraction, compounds 4, 9, and 12 underwent extensive NADPH-dependent metabolism with concomitant generation of alkylating activity under both hypoxic and oxic conditions. Corresponding ketone metabolites were detected for 9 and 15. NADPH-dependent bioreduction of 15 to its ketone metabolite 16 was located in the microsomal fraction and inhibited by SKF-525A and pCMBA. Compared with phenobarb-induced rat liver microsomal fraction, incubation of 15 with rat or human P450 reductase microsomes showed moderate generation of 16. Microsomal cytochrome P450 and/or P450 reductase appear to be involved in the reductive metabolism of 1,2-benzisoxazole moiety under hypoxic as well as oxic conditions.

Rather efficient catalysis of the decomposition of 5-nitro-benzisoxazole to the cyanophenol was observed with antibodies elicited against a cationic hapten structurally unrelated to the benzisoxazole substrate. The rate enhancement by the most active antibody is better than 10(4) and the reaction is catalyzed by a carboxylate group associated with a hydrophobic binding site. (C) 1997 Elsevier Science Ltd.

4-{4-[4-Tetrahydrofuran-3-yloxy)-benzo[d]isoxazol-3-yloxymethyl]-piperidin-1-ylmethyl}-tetrahydropyran-4-ol (PF-4995274, TBPT) is a new agent that is a partial agonist of the human serotonin-4 (5-HT4) receptor and is under investigation for neurological disorders. Metabolism of TBPT was examined in vitro in human liver microsomes and human hepatocytes. Metabolites were also identified in the plasma of healthy human subjects in a phase 1 clinical study. Human-derived metabolite profiles were compared with corresponding profiles obtained in laboratory animal species. There were two major routes of metabolism in vitro: N-dealkylation of the methyltetrahydropyran moiety (M1) and hydroxylation at the seven position of the benzisoxazole moiety (M4). These were also observed in human plasma; however, in that matrix, the major metabolite was an unusual cyclized oxazolidine entity (M2). M2 was proposed to be formed via generation of an intermediate 4. iminium ion on the piperidine ring followed by spontaneous cyclization by attack of the beta-hydroxyl substituent of the tetrahydropyran ring to form a cyclized oxazolidine product. An authentic standard of the metabolite was generated using a methylene-blue-sensitized photochemical oxidation reaction as well as microbial transformation. Further investigation of this metabolite showed that it also possessed 5-HT4 agonism activity similar to the parent. The metabolite was 150-fold more highly protein bound in human plasma than TBPT, which is consistent with its presence as a major circulating metabolite while being only a minor metabolite in in vitro systems. Overall, this illustrates the importance of understanding the complex dispositional properties of a pharmacologically active metabolite. (C) 2013 Wiley Periodicals, Inc.

Risperidone as a treatment for Tourette’s syndrome

Background: An open-label trial was performed to assess the efficacy and safety of risperidone, a benzisoxazole derivative with potent D-2 and 5-HT2 antagonism, for treatment of Tourette’s syndrome. Method: Thirty-eight patients with Tourette’s syndrome volunteered to take risperidone for treatment of their tics. All patients had failed to respond adequately to conventional treatments (with neuroleptics such as haloperidol and/or with the alpha(2)-adrenergic agonist clonidine) or had suffered from intolerable side effects from such treatments. Patients were rated for tic severity by the Yale Global Tic Severity Scale (YGTSS) before treatment and after 1 month of treatment with risperidone. Patients were monitored carefully for side effects and clinical response. Results: Of the 38 patients, 8 discontinued risperidone treatment before the end of the trial because of intolerable side effects. At the end of the 4-week trial, 22 patients (58%) were improved, 7 patients (18%) had no appreciable change in their symptoms, and 1 patient (3%) had a documented worsening of tics. Doses of risperidone at the end of the trial ranged from 0.5 mg to 9 mg/day (mean = 2.7 mg/day). Conclusion: This open clinical trial suggests that risperidone may be a promising alternative to conventional medications used for treating the symptoms of Tourette’s syndrome.

Monitoring of zonisamide in human breast milk and maternal plasma by solid-phase extraction HPLC method

An HPLC method was developed for the determination of zonisamide in human breast milk and plasma. Chromatographic separation was achieved using a Develosil CN analytical column with potassium dihydrogenphosphate buffer (pH 3.5 with milk, pH 2.5 with plasma)-acetonitrile as the mobile phase. Zonisamide and 1,2-benzisoxazole-3-methansulfonamine acetate as internal standard were detected by ultraviolet absorbance at 240 nm. Zonisamide in breast milk and plasma was extracted by a rapid and simple procedure based on C-18 bonded-phase extraction. Determination of zonisamide in human breast milk and plasma was possible in the concentration range 0.05-20.0 mu g/mL. The recoveries of zonisamide added to human breast milk and plasma were 79.5-85.0% and 86.3-93.1%, respectively, with coefficients of variation of less than 8.3% and 11.4% respectively. The mean concentrations of zonisamide in breast milk and plasma were 9.41 +/- 0.95 and 10.13 +/- 0.45 mu g/mL, respectively. The average ratio between the breast milk concentration and plasma concentration (M/P ratio) was 0.93 +/- 0.09. Copyright (C) 1999 John Wiley & Sons, Ltd.

Genotyping as a Key Element of Sample Size Optimization in Bioequivalence of Risperidone Tablets

Risperidone is a derivative of benzisoxazole and is widely used for schizophrenia and other psychiatric illnesses in both adults and children. Previous studies have confirmed that it is a highly variable drug (within-subject variability >= 30%). To reduce the large sample size required for bioequivalence researches on highly variable drugs, a role for genotyping in the design of the bioequivalence study was employed. A randomized, open-label, two-period crossover study was adopted: 20 subjects with specific genotypes carrying cytochrome P450 (CYP) 2D6*10 were randomized to two groups to receive a single oral dose of trial formulation or reference formulation with a 2-week washout period. Blood concentrations of risperidone (parent drug) and 9-hydroxy risperidone (active metabolite) were measured by high-performance liquid chromatography-tandem mass spectrometry. Eighteen out of the 20 subjects completed the study (two did not finish the test in the second period). The pharmacokinetic parameters of AUC(last), AUC(a) and C (max) for the 18 subjects after a single oral dose of the trial or reference preparation were 216.1 +/- 88.7 and 220.5 +/- 96.8 ng center dot h/mL; 221.6 +/- 93.1 and 226.4 +/- 103.5 ng center dot h/mL; 36.7 +/- 10.3 and 36.0 +/- 10.2 ng/mL, respectively. The CVw of risperidone in natural logarithm-transformed C (max) was 22.4 and 25.38% for 9-hydroxy risperidone. The test formulation met the Food and Drug Administration guidelines and regulation criteria for bioequivalence. By controlling the genotype, it could actually help reduce the CVw, which may be a feasible method to decrease the sample size for the bioequivalence study of highly variable drugs.
