Activation by zonisamide, a newer antiepileptic drug, of large-conductance calcium-activated potassium channel in differentiated hippocampal neuron-derived H19-7 cells

Zonisamide (ZNS; 3-sulfamoylmethyl-1,2-benzisoxazole), as one of the newer antiepileptic drugs, has been demonstrated its broad-spectrum clinical efficacy on various neuropsychiatric disorders. However, little is known regarding the mechanism of ZNS actions on ion currents in neurons. We thus investigated its effect on ion currents in differentiated hippocampal 19-7 cells. In whole-cell configuration of patch-clamp technology, the ZNS (30 mu M) reversibly increased the amplitude of K+ outward currents, and paxilline (1 mu M) was effective in suppressing the ZNS-induced increase of K+ outward currents. In inside-out configuration, ZNS (30 mu M) applied to the intracellular face of the membrane did not alter single-channel conductance; however, it did enhance the activity of large-conductance Ca2+-activated K+ (BKCa) channels primarily by decreasing mean closed time. In addition, the EC50 value for ZNS-stimulated BK Ca channels was 34 mu M. This drug caused a left shift in the activation curve of BK Ca channels, with no change in the gating charge of these channels. Moreover, ZNS at a concentration greater than 100 mu M also reduced the amplitude of A-type K+ current in these cells. A simulation modeling based on hippocampal CA3 pyramidal neurons (Pinsky-Rinzel model) was also analyzed to investigate the inhibitory effect of ZNS on the firing of simulated action potentials. Taken together, this study suggests that, in hippocampal neurons during the exposure to ZNS, the ZNS-mediated effects on BK Ca channels and A-type K+ current could be potential mechanisms through which it affects neuronal excitability.

Reactivity of 2,1-Benzisoxazole in Palladium-Catalyzed Direct Arylation with Aryl Bromides

The Pd-catalyzed direct arylation of 2,1-benzisoxazole with aryl bromides to access 3-arylbenzoisoxazoles proceeds in moderate-to-high yields with 1mol% Pd(OAc)(2) or 2mol% PdCl(C3H5)(dppb) (dppb=1,4-bis(diphenylphosphino)butane) as the catalysts and KOAc as an inexpensive base. A wide variety of (hetero)aryl bromides have been employed successfully. Moreover, arylations followed by benzisoxazole ring opening allowed the preparation of 2-aminobenzophenones in only two steps.

EFFICACY AND TOLERABILITY OF A NEW ANTIPSYCHOTIC COMPOUND (RISPERIDONE) – RESULTS OF A PILOT-STUDY

Risperidone is a new benzisoxazole derivative displaying a very potent serotonin antagonism and a potent dopamine antagonism in pharmacological studies. These properties suggest the hypothesis that risperidone may exert antipsychotic effects and be superior to classic neuroleptics in its beneficial effects on negative and affective symptoms and its low extrapyramidal side-effect propensity. In an open pilot study 13 patients suffering from acute schizophrenic psychosis were treated with risperidone within an individually adapted dose range from 1 to 10 mg per day. A good antipsychotic efficacy could be demonstrated in 6 of the 8 patients who completed the trial. Risperidone was very well tolerated. The substance possesses a low EPS-inducing profile. Future research has to test the suggested advantage of risperidone over other neuroleptic drugs and its performance in the treatment of chronic schizophrenic patients.

Reactivity of the ester group attached isoxazoline, benzisoxazole, and isoxazole: a facial preparation of 3-acyl-substituted these heterocycles

A facile preparation of 3-acyl-substituted isoxazolines, benzisoxazoles, and isoxazoles from the corresponding 3-carboxylate esters is described. The process, involving reaction of the ester derivative of 3-carboxylic acid substituted heterocycles with Grignard or alkynyl lithium reagents, leads to direct generation of the corresponding 3-acyl heterocycle. The presence of alpha-imino ester moieties in the heterocyclic substrates for the reactions is thought to be a key feature governing the nature of these transformations. The synthetic utility of the new methodology is demonstrated by its application in a two-step route for the preparation of novel linked bis-heterocycles. (C) 2012 Elsevier Ltd. All rights reserved.

SYNTHESIS OF 1,2-BENZISOXAZOLE 2-OXIDES

A series of 2-hydroxyaryl ketoximes were converted to the corresponding 1,2-benzisoxazole 2-oxides by treatment with iodobenzene diacetate (in acetic acid or methanol) or N-chlorosuccinimide in water. Both methods gave moderate to excellent yields for a variety of substituted oximes under mild conditions within short reaction times. The latter method has the advantages of an aqueous solvent and lack of halogenated organic by-products.

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.

EFFECTS OF ZONISAMIDE ON EXTRACELLULAR LEVELS OF MONOAMINE AND ITS METABOLITE, AND ON CA-2+ DEPENDENT DOPAMINE RELEASE

The effects of zonisamide (3-sulfamoylmethyl-1,2-benzisoxazole), a novel anticonvulsant, on extracellular levels of monoamine and its metabolite in the striatum and hippocampus, and Ca2+ dependent monoamine release in the striatum of freely moving rats were studied by microdialysis. Zonisamide increased dopamine, homovanillic acid and 5-hydroxyindoleacetic acid, and decreased 3,4-dihydroxyphenylacetic acid in the rat striatum. However, zonisamide showed no effect on Ca2+ dependent dopamine release in the rat striatum. In the hippocampus, zonisamide increased dopamine, homovanillic acid, serotonin and 5-hydroxyindoleacetic acid and decreased 3,4-dihydroxyphenylacetic acid. The present results suggest that zonisamide facilitates dopaminergic and serotoninergic neurotransmission but does not affect Ca2+ dependent dopamine release within therapeutic plasma concentrations.

Process improvements for the preparation of kilo quantities of a series of isoindoline compounds

A series of isoindoline analogues with either an indazole (HMR 2934, HMR 2651) or benzisoxazole (HMR 2543) appendage were prepared for the proposed treatment of psychiatric disorders such as obsessive compulsive disorder and attention deficit disorder. The isoindoline compounds were prepared by reduction of the corresponding phthalimides with LiAlH4. One compound was not chiral, and the other two required an enantioselective synthesis. The key step for these optically active analogues involved the coupling by an S(N)2 process of either a piperazynyl intermediate or a piperdinyl intermediate with methyl 3-benzyloxy-2-trifluoromethansulfonatopropionate. The products for these two analogues had >98% ee. Process improvements led to the multi-kilogram syntheses of each of these compounds.
