Catalysis of 3-carboxy-1,2-benzisoxazole decarboxylation by hydrophobic antibody binding pockets

Monoclonal antibodies were generated against a 3-phenyl-1,2-benzisoxazole derivative and shown to catalyze the solvent-sensitive decarboxylation of 3-carboxy-1,2-benzisoxazoles. In addition to rare accelerations up to 2300-fold over background, the antibodies exhibit distinctive selectivities for substrates bearing 5- or 6-NO2 substituents, with preferential decarboxylation of the less reactive substrate in one case. These effects are the likely consequence of substrate destabilization, achieved by forcing the carboxylate group into a relatively apolar binding pocket and stabilization of the charge-delocalized transition state through dispersive interactions. Comparison with a more active antibody decarboxylase previously raised against 2-acetamido-naphthalene-1,5-disulfonate suggests, however, that a judicious mix of polar and apolar interactions may ultimately be more effective for achieving high decarboxylase activity.

Paliperidone in the treatment of delirium: results of a prospective open-label pilot trial

Objective: Delirium is a life-threatening neuropsychiatric syndrome characterised by disturbances in consciousness, attention, cognition and perception. Antipsychotics are considered the drugs of choice in managing the symptoms of delirium. Paliperidone is a benzisoxazole derivative and the principal active metabolite of risperidone. In this study, we aimed to evaluate the efficacy of paliperidone for the treatment of delirium. Methods: A prospective open-label study of paliperidone for delirium treatment was performed with 6-day follow-up. Fifteen patients who met Diagnostic and Statistical Manual of Mental disorders, Fourth Edition criteria for delirium and had a score of 13 on the Delirium Rating Scale were recruited. The starting dose was 3 mg once a day and the dose was adjusted depending on the status of delirium. Daily assessments of the severity of delirium were evaluated using Memorial Delirium Assessment Scale (MDAS). Results: The mean daily maintenance dose of paliperidone was 3.75 +/- 1.06. The MDAS scores before and after treatment (day 7) were 23.60 +/- 6.31 and 11.33 +/- 5.45 (t = 6.78, p < 0.001), respectively. The intensity of delirium showed a statistically significant reduction in MDAS scores from the first day of treatment. No serious adverse effects were observed, and none of the patients discontinued paliperidone because of adverse effects. Conclusions: This study shows that low-dose paliperidone is effective in reducing behavioural disturbances and symptoms in delirium and is well tolerated in delirious patients. This trial is an open-label study with a small sample size, and further controlled studies will be necessary. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

On the Photochemistry of 1,2-Benzisoxazole: Capture of Elusive Spiro-2H-azirine and Ketenimine Intermediates

The photochemistry of 1,2-benzisoxazole (1) was studied using low-temperature matrix isolation coupled with infrared spectroscopy and quantum chemistry calculations. We identified, for the first time, spiro-2H-azirine 2 and ketenimine 3 as intermediates in the photoisomerization of 1 to 2-cyanophenol (4). These results constitute indirect evidence for the existence of vinylnitrene intermediates in the photochemistry of 1,2-benzisoxazoles. The potential energy surface (PES) resulting from the N-O bond cleavage of 1 was compared with the respective PES of the parent isoxazole. Calculations at the CBS-QB3 level show that no stabilization is gained for the triplet vinylnitrene upon introduction of a benzene ring fused with isoxazole. However, the energies of 2 and 3 are higher by 13-15 kcal/mol comparing with the 2H-azirine and ketenimine analogs resulting from isoxazole, which explains why they had not been observed before. Our general mechanistic proposal also predicts well the photoisomerizations of 2 and 3 to 4.

RISPERIDONE – AN ATYPICAL AGENT APPROVED AS 1ST-LINE THERAPY FOR MANAGING MANIFESTATIONS OF PSYCHOTIC DISORDERS

Risperidone, a benzisoxazole derivative, was recently approved by the FDA for the management of psychotic disorders. It joins clozapine as the second antipsychotic agent to become available that possesses both dopaminergic and serotoninergic blocking activities. Risperidone has been shown to improve the positive and negative symptoms of schizophrenia in clinical trials. The drug can be used as a first-line agent and trials are currently being conducted to establish its benefit in treatment-refractory patients. Risperidone is associated with a low incidence of extrapyramidal symptoms, has not been associated with tardive dyskinesia, and does not require hematological monitoring. The availability of risperidone represents progress not only in the pharmacotherapy of schizophrenia, but also in the understanding of the pathophysiology of this disorder.

Reactivity of Lithium beta-Ketocarboxylates: The Role of Lithium Salts

Lithium beta-ketocarboxylates 1(COOLi), prepared by the reaction of lithium enolates 2(Li+) with carbon dioxide, readily undergo decarboxylative disproportionation in THF solution unless in the presence of lithium salts, in which case they are indefinitely stable at room temperature in inert atmosphere. The availability of stable THF solutions of lithium beta-ketocarboxylates 1(COOLi) in the absence of carbon dioxide allowed reactions to take place with nitrogen bases and alkyl halides 3 to give alpha-alkyl ketones 1(R) after acidic hydrolysis. The sequence thus represents the use of carbon dioxide as a removable directing group for the selective monoalkylation of lithium enolates 2(Li+). The roles of lithium salts in preventing the disproportionation of lithium beta-ketocarboxylates 1(COOLi) and in determining the course of the reaction with bases and alkyl halides 3 are discussed.
