Structure elucidation of compounds in the benzisoxazole series (1-6) and naphtho[1,2-d][1,3] (7-10) and phenanthro[9,10-d][1,3]oxazole (11-14) series was accomplished using extensive 2D NMR spectroscopic studies including H-1-H-1 COSY, long-range H-1-H-1 COSY,H-1-C-13 COSY, gHMQC, gHMBC and gHMQC-TOCSY experiments. The distinction between oxazole and isoxazole rings was made on the basis of the magnitude of heteronuclear one-bond (1)J(C2,H2) (or (1)J(C3,H3)) coupling constants. Complete analysis of the H-1 NMR spectra of 11-14 was achieved by iterative calculations. Gradient selected gHMQC-TOCSY spectra of phenanthro[9,10-d][1,3]oxazoles 11-14 were obtained at different mixing times (12,24,36,48 and 80 ms) to identify the spin system where the protons of phenanthrene ring at H-5, H-6 and at H-9 and H-7 and H-8 were highly overlapping.

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.

Rapid and High-Yield Electrosynthesis of Benzisoxazole and Some Derivatives

Cyclic voltammetry and controlled-potential (bulk) electrolysis have been used to explore the electrochemical reduction of o-nitrobenzaldehyde (o-NBA) and 8 other aldehydes and ketones at glassy carbon cathodes in dimethylformamide containing various tetraalkylammonium tetrafluoroborate salts along with a proton donor (4-chlorophenol). Cyclic voltammograms for reduction of o-NBA exhibit three cathodic peaks attributable in succession to (a) one-electron generation of the nitro radical-anion, (b) three-electron formation of the hydroxylamine, and (c) two-electron production of benzisoxazole (anthranil). These findings have been employed to develop efficient controlled-potential (bulk) electrosyntheses of the following compounds: benzisoxazole, methylbenzo[c]isoxazole, [1,3]dioxolo[4 ‘,5 ‘,4,5]benzo[1,2-c]isoxazole, naphtho[2,3-c]isoxazole, 6-chlorobenzo[c]isoxazole, 6-methoxybenzo[c]isoxazole, 3-methyl-benzo[c]isoxazole, 3-isopropylbenzo[c]isoxazole, and 3-phenylbenzo[c]isoxazole. In addition, we have examined the use of a variety of proton donors to optimize the production of the desired product, and we have been able to recover the proton donor at the conclusion of the electrosynthesis. In each case, the synthesized product was separated by means of normal phase chromatography and identified with the aid of NMR spectros-copy, gas chromatography (GC), and gas chromatography-mass spectrometry (GC-MS). Isolated yields of the desired products range from 63 to 92 %. Moreover, our electrosyntheses are catalyst-free, environmentally green, and rapid (similar to 30 min).

Safety and Efficacy of Zonisamide in Refractory Epilepsy Patients: Clinical Experience from a Tertiary Center

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.

Review of zonisamide development in Japan

Zonisamide is a benzisoxazole-based compound first synthesized in the early 1970s by the research laboratories of Dainippon Pharmaceutical Company in Osaka, Japan. Identified as an anticonvulsant during exploratory research, zonisamide has since been characterized as having broad-spectrum antiepitepsy and neuroprotective effects. Early clinical studies in Japan demonstrated that zonisamide has a long elimination half-life and is well tolerated; Phase II and III clinical trials established the drug’s efficacy and safety for the treatment of partial and generalized seizures. In 1989, zonisamide was approved and marketed in Japan under the trade name of Excegran(R). Data from postmarketing surveillance studies and clinical observations over 10 years of use have continued to support zonisamide’s efficacy and safety, identified its usefulness as monotherapy, and characterized its effectiveness for various seizure types and epilepsy syndromes.

Bacterial Degradation of Risperidone and Paliperidone in Decomposing Blood

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high-performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37 degrees C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7 degrees C, but degraded significantly in inoculated blood at 20 and 37 degrees C. Complete loss occurred within 2 days when incubated at 37 degrees C. The benzisoxazole-cleaved degradation products for both drugs were identified as 2-hydroxybenzoyl-risperidone and 2-hydroxybenzoyl-paliperidone utilizing liquid chromatography quadrupole-time-of-flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ.
