The widespread use of toxic phosphates and phosphonates as insecticides, and their use as chemical weapons, has led to investigation of fast detoxification and decontamination methods. Micelles, microemulsions, cyclodextrines and liposomes have been used to accelerate phosphate ester decomposition by nucleophiles. Here, hydrolysis, methanolysis and hexanolysis of Tris-p-nitrophenyl phosphate (TNPP), a model for reactive phosphate esters. were studied in homogeneous phase, aqueous and reverse micelles. Kinetic micellar effects were quantitatively analyzed using pseudo-phase models. TNPP hydrolysis was catalyzed by cetyltrimethylammonium chloride (CTAC), cetyltrimethylammonium bromide (CTAB). and hexadecylammonium propanesulfonate (HPS), micelles by factors of five, CTAC, and three. CTAB, HPS, respectively. The calculated rate constants for spontaneous and acetate-catalyzed hydrolysis in the micellar phase were significantly higher than those in the aqueous phase. While in water and in methanol the effect of the acetate cation was negligible, the catalytic efficiency of acetate for hexanolysis depended on the nature of the cation with the K+ salt being ca. 20 times more efficient than the tetraethylammonium salt in non-polar solvents. Sodium dodecylsulfate, SDS. micelles inhibited TNPP hydrolysis by a factor of eigth. Reverse micelles of CTAB in n-hexanol/isooctane (10:90, v/v) did not catalyze TNPP hydrolysis, but changed the bis-p-nitrophenyl phosphate/hexyl-bis-p-nitrophenylphosphate product ratio depending of CTAB concentration and water/detergent ratio.

Objectives: Zonisamide (ZnS) is a new generation antiepileptic agent used in the treatment of epilepsy patients with partial and generalized seizures. In this study, we aim to investigate the safety and efficacy of ZnS in the treatment of patients with refractory epilepsy who were being followed. Methods: Forty-five refractory epilepsy patients who received ZnS treatment were included in this study. Patients who received ZnS treatment for less than six months were excluded. Age, sex, types of seizures, examination findings, magnetic resonance imaging and electroencephalography findings, concurrent use of non-ZnS antiepileptic drugs, decrease in the seizure frequency and side effects of the drug were recorded. Results: Thirty-nine patients, whose mean age was 34.3 +/- 9.3 years, were evaluated. Complex partial seizures (CPS) and generalized tonic-clonic seizure (GTCS) were observed in 74.4% of the patients, whereas 10.3% had GTCS alone, 7.7% had CPS alone, 5.2% had GTCS and myoclonia and 2.6% of them had absence and myoclonia. In the follow-up, treatment was observed to be discontinued in 19 of the 39 patients due to drug side effects, or where there was an increase, or no change, in seizure frequency. Twenty patients responded to treatment. Seizure frequency was decreased by 25% in one patient; 50% in five patients, and 75% in seven patients. Three patients were seizure-free. Although there was no change in seizure frequency, seizure duration was shortened in four patients. Treatment-responsive patients were using ZnS at doses that ranged from 100 to 400 mg/day for 7 to 80 months. Conclusion: ZnS is a safe, tolerable and effective option for the additional treatment of refractory epilepsy patients at our center.

Reaction of 1-nitro-4-(1,2,3-triazolyl/tetrazolyl)benzenes with arylacetonitriles in an alcoholic medium in the presence of excess alkali gives novel 2,1-benzisoxazoles. These findings indicate a high reactivity of nitroarenes activated by the azole ring due to their electron-deficient character. Moreover, it was found that annulation of the isoxazole ring occurred regioselectively in disubstituted nitroarenes. In the case of 1-(4-nitrophenyl)-1H-tetrazole, the tetrazole ring cleaved faster than the sigma(H)-adduct was formed.

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.

Zonisamide, a widely available antiepileptic drug, has been approved in Japan as adjunctive therapy with levodopa for the treatment of previously treated patients with Parkinson’s disease. It is an oral 1,2-benzisoxazole-3-methanesulfonamide and is associated with increased striatal dopamine levels in animal models. In two 12-week, randomized, double-blind, multi-centre trials in adult patients with inadequately controlled Parkinson’s disease and receiving levodopa, zonisamide 25 mg once daily (the recommended dosage) significantly improved motor function from baseline at final assessment, as assessed by the Unified Parkinson’s Disease Rating Scale (UPDRS) Part III total score (primary endpoint), compared with placebo. Zonisamide 25 mg once daily as adjunctive therapy with levodopa was generally well tolerated by patients with Parkinson’s disease. The overall incidence of adverse events was not significantly different between zonisamide 25mg once daily and placebo groups in the phase IIb/III trial.

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.

Synthetic Route of 505-48-6, New Advances in Chemical Research, May 2021.Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur, causing turnover rates to depend strongly on interfacial structure and composition. 505-48-6, Name is Octanedioic acid, SMILES is C(C(O)=O)CCCCCC(O)=O, belongs to benzisoxazole compound.

Purpose. The efficacy, safety, pharmacology, pharmacokinetics, drug-drug interactions, and administration of paliperidone for schizophrenia are reviewed. Summary. Paliperidone is a benzisoxazole derivative and the principal active metabolite of risperidone. Representative of most oxidative metabolites, paliperidone is less lipophilic than risperidone. Like other atypical antipsychotics, paliperidone has a greater affinity for serotonin type 2A-receptor blockade relative to dopamine type 2-receptor blockade. Paliperidone’s advanced-gene ration osmotic release delivery system allows for the avoidance of dosage adjustment when initiating therapy and may decrease the frequency of antidopaminergic effects that would occur with an immediate-release formulation. The pharmacologic actions of paliperidone are similar to other high potency atypical antipsychotics. The receptor-binding profile of paliperidone most closely resembles that of risperidone and ziprasidone. Paliperidone differs from risperidone and most other antipsychotics by its relatively low extent of enzymatic metabolism. A limited number of investigations have demonstrated the ability of paliperidone to produce significant improvements in psychopathology, functioning, and relapse in patients with schizophrenia when compared with placebo. Paliperidone appears to have a similar adverse-effect profile compared to risperidone, except for an increased rate of hyperprolactinemia. The recommended dose of paliperidone for the treatment of adults with schizophrenia is 6 mg every morning. Conclusion. Paliperidone does not offer any clear advantage over other atypical antipsychotics with a similar receptor-binding profile, such as risperidone and ziprasidone. Nevertheless, a few investigations have demonstrated the ability of paliperidone to produce significant improvements in psychopathology, functioning, and relapse when compared with placebo. Based on limited studies, the frequency of adverse effects, except for hyperprolactinemia, appears to favor paliperidone over risperidone.

Quetiapine fumarate (QTF) is an antipsychotic drug belonging to the benzisoxazole derivatives indicated for the treatment of schizophrenia. A sensitive and selective method based on dichloromethane-extractable ion-pair of QTF with calmagite (CGT), which exhibited an absorption maximum at 490 nm, is described. At this. wavelength, Beer’s law is obeyed over the concentration range of 3.0-30.0 mu g ml(1). The apparent molar absorptivity, limit of detection (L OD) and quantitation (LOQ) values are 1.32×10(4) I mol(1) cm(-1), 0.27 and 0.81 mu g ml(1), respectively. The reaction is extremely rapid at room temperature and the absorbance values remain unchanged up to 19 h. The precision results, expressed as intra-day and inter-day relative standard deviation values, are satisfactory (RSD <= 2.2%). The accuracy is satisfactory as well (RE <= 2.44%). The method was successfully applied to the determination of QTF in pharmaceuticals and spiked human urine with satisfactory results. No interference was observed from common pharmaceutical adjuvants in tablets. Statistical comparison of the results with the official method showed an excellent agreement and indicated no significant difference in precision. Interested yet?
