Design and synthesis of (5-amino-1, 2, 4-triazin-6-yl)(2-(benzo[d] isoxazol-3-yl) pyrrolidin-1-yl)methanone derivatives as sodium channel blocker and anticonvulsant agents

A series of novel (5-amino-3-substituted-1, 2, 4-triazin-6-yl) (2-(6-halo-substituted benzo[d]isoxazol-3-yl) pyrrolidin-1-yl) methanone 5a-5r was synthesized. Their anticonvulsant activities were evaluated by the maximal electroshock (MES) test and neurotoxicity was evaluated by the rotorod test. The MES test showed that (5-amino-3-phenyl-1, 2, 4-triazin-6-yl)(2-(6-fluorobenzo[d]isoxazol-3-yl) pyrrolidin-1-yl) methanone 5c was found to be the most potent compound with ED50 value of 6.20 mg/kg (oral/rat) and a protective index (PI = ED50/TD50) value of >48.38, which was much higher than the PI of the reference drug phenytoin. To explain the possible mechanism of action of selected derivatives 5b, 5c, 5i and 5o, their influence on sodium channel was evaluated in vitro.

Formation of 2-sulphamoylacetylphenol from zonisamide under aerobic conditions in rat liver microsomes

1. The antiepileptic agent zonisamide, 1,2-benzisoxazole-3-methanesulphonamide, was metabolized reductively to 2-sulphamoyl-acetylphenol (SMAP) not only under anaerobic conditions but also under aerobic conditions in liver microsomes of rat pretreated with phenobarbital or dexamethasone. 2. NADPH was required for the formation of SMAP from zonisamide under aerobic conditions. In addition, the reductive metabolism of zonisamide under these conditions was substantially inhibited by carbon monoxide, ketoconazole, and cimetidine, known inhibitors of cytochrome P450. 3. The formation of SMAP under aerobic conditions in liver microsomes was increased by pretreatment of rat with triacetyloleandomycin (TAO) and was increased by the treatment of the microsomes with ferricyanide. 4. These results imply that zonisamide is metabolized reductively to SMAP by a cytochrome P450 belonging to the 3A subfamily under aerobic conditions as well as anaerobic conditions.

Medium Effects in Biologically Related Catalysis

Enzymes catalyze chemical reaction in aqueous media, but their active sites significantly differ in properties from water. In this chapter, the work on selected chemical reactions with important biological roles is reviewed to assess our current understanding of the effect of the environment that surrounds the reactive species. In particular, simple medium effects such as the ones provided by organic solvents, ionic liquids, and simple micelles are focused on. The findings that led to the computational design of enzymes that catalyze the Kemp elimination, a prototypical proton transfer reaction that has fascinated researchers for more than a century, are discussed.

High-performance liquid chromatographic assay of zonisamide (1,2-benzisoxazole-3-methanesulfonamide) in human plasma using a solid-phase extraction technique

A selective and sensitive liquid chromatographic method was developed for the determination of zonisamide in small volumes of plasma. Zonisamide and the internal standard methyl 4-hydroxybenzoate were extracted from 0.2 mL. of plasma with solid-phase extraction columns and eluted with methanol. Analysis of the extracts was performed on a Symmetry C-18 column with ultra-violet spectrophotometric detection. The calibration curve was linear over the concentration range of 0.05-5 mug mL(-1) in plasma. Recoveries were reasonable for routine analyses; the limit of quantification was 0.05 mug mL(-1) with a signal-to-noise ratio of 5. This method could be useful for the pharmacokinetic study of zonisamide in a limited volume of human plasma and for therapeutic drug monitoring.

Iloperidone for the Treatment of Schizophrenia

OBJECTIVE: To review the pharmacology, pharmacokinetics, efficacy, and safety data of iloperidone for the treatment of schizophrenia. DATA SOURCES: Data were selected by searching Pre-MEDLINE, MEDLINE, and International Pharmaceutical Abstracts (1966 January 2010). Abstracts, scientific posters, and unpublished data provided by the manufacturer in the English language were also assessed. STUDY SELECTION AND DATA EXTRACTION: All published data including pharmacologic, pharmacokinetic, pharmacodynamic, and clinical studies related to iloperidone were considered for inclusion. Selected studies included randomized controlled trials, abstracts, and posters presented at national scientific meetings providing pertinent data. data synthesis: Iloperidone is a benzisoxazole phenylethanone with a higher affinity for serotonin-2a than dopamine-2 receptors. The recommended therapeutic total daily dose is 12-24 mg divided in 2 doses titrated over 1 week to avoid orthostasis. Acute, 6-week, randomized, placebo-controlled, and active-controlled studies demonstrated iloperidone’s efficacy in reducing psychotic symptoms according to changes in the total positive and negative symptom scale (PANSS-T) score from baseline. A long-term maintenance trial demonstrated similar efficacy with haloperidol in preventing time to relapse. Pharmacogenomic studies reported possible single nucleotide polymorphisms related to QT interval prolongation and efficacy with iloperidone. Common adverse effects included dizziness, dry mouth, and sustained orthostasis occurring more frequently with higher doses. Weight gain is possible at any dose. Additionally, studies showed that QTc interval prolongation may be dose related. The incidence of extrapyramidal symptoms appears to be low across all dosage ranges; however, akathisia may be more frequent with higher doses. CONCLUSIONS: Iloperidone demonstrated efficacy in acute exacerbations and long-term maintenance in adults with schizophrenia. Caution may be warranted in elderly patients and patients with cardiac disease, due to orthostasis. Further studies regarding pharmacogenomic testing related to the drug’s efficacy and tolerability are needed to justify its routine use in practice.

Polymorphic and solvate structures of ethyl ester and carboxylic acid derivatives of WIN 61893 analogue and their stability in solution

3-Ethyl ester- (1) and 3-carboxylic acid-isoxazole (2) derivatives of an antiviral drug analogue WIN 61893 were synthesized and characterized by X-ray crystallography and NMR spectroscopy. Crystallization experiments afforded two polymorphic structures for the ethyl ester derivative and two solvate structures for the carboxylic acid derivative based on their ability to form intermolecular hydrogen bonding interactions with the solvent molecules. The conformations of the derivatives depended greatly on the orientation of the planar isoxazole and phenyl-oxadiazole ring systems with respect to one another and were found to take up perpendicular, linear or tilted conformations. The carboxylic acid derivative was furthermore observed to undergo isoxazole ring cleavage by decarboxylation in DMSO solution and transforming into a beta-keto nitrile ring-opening product over several days, whereas, the isoxazole ring of the ethyl ester derivative was not affected.

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.
