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.

ANALYSIS OF SOLVENT EFFECTS ON THE DECARBOXYLATION OF BENZISOXAZOLE-3-CARBOXYLATE IONS USING LINEAR SOLVATION ENERGY RELATIONSHIPS – RELEVANCE TO CATALYSIS IN AN ANTIBODY-BINDING SITE

The mechanisms by which specific solvent properties influence the title reaction, which is extremely medium-sensitive, have been investigated using multiparametric methods. The results of this analysis have been compared with previous experimental studies of the reaction mechanism. Hydrogen-bond donation by solvent and hydrogen-bond donation by tetramethylguanidinium ion in tight ion pairs with the carboxylate greatly retard the reaction. Solvent dipolarity and basicity accelerate the reaction, most likely by helping to break up hydrogen-bonded ion pairs. The rate of decarboxylation in the binding pocket of a catalytic antibody developed for this reaction is slower than that expected of a free carboxylate in an aprotic environment. Therefore, the binding site may contain a hydrogen-bond-donating species. A better catalyst might be developed by approaches that reduce hydrogen bonding in the active site without reducing substrate binding.

Highly efficient catalysis of the Kemp elimination in the cavity of a cubic coordination cage

The hollow cavities of coordination cages can provide an environment for enzyme-like catalytic reactions of small-molecule guests. Here, we report a new example (catalysis of the Kemp elimination reaction of benzisoxazole with hydroxide to form 2-cyanophenolate) in the cavity of a water-soluble M8L12 coordination cage, with two features of particular interest. First, the rate enhancement is among the largest observed to date: at pD 8.5, the value of k(cat)/k(uncat) is 2 x 10(5), due to the accumulation of a high concentration of partially desolvated hydroxide ions around the bound guest arising from ionpairing with the 16+ cage. Second, the catalysis is based on two orthogonal interactions: (1) hydrophobic binding of benzisoxazole in the cavity and (2) polar binding of hydroxide ions to sites on the cage surface, both of which were established by competition experiments.

1,2-Benzisoxazole-3-acetamide derivatives as dual agents for DPP-IV inhibition and anticancer activity

Herein, we have designed various benzisoxazole acetamide derivatives with and without glycine spacer as DPP-IV inhibitors. Compounds 9a-d and 11a-e were synthesized and screened for their in vitro DPP-IV inhibition. Compounds 11a and 11c showed moderate activity for DPP-IV inhibition, whereas other remained inactive at 25-200 mu M concentrations. DPP-IV inhibition can be a good strategy for modulating diabetes and cancer; hence, we have screened compounds 9a-d and 11a-e for their anticancer activity using MTT assay against A549 and MCF7 cell lines. Compounds 9a-d without glycine spacer have shown good anticancer activity compared to compounds 11a-e with glycine spacer. Compound 9b has shown moderate activity with IC50 values 4.72 +/- 0.72 and 4.39 +/- 0.809 mu M against A549 and MCF7 cell lines, respectively. Interestingly, compound 9c with cyano group has shown very good anticancer activity with IC50 2.36 +/- 0.34 mu M against MCF7 cell line as compared to fluorouracil with IC50 45.04 +/- 1.02 mu M.

Clinical experience with zonisamide monotherapy and adjunctive therapy in children with epilepsy at a tertiary care referral center

We evaluated our clinical experience with zonisamide, a broad-spectrum antiepileptic drug, in a group of children with predominantly medically refractory epilepsy. A retrospective chart review was conducted on patients at our tertiary referral center following Institutional Review Board approval. Observers documented reports of seizure frequency, and seizure types were identified either clinically or by prior video-electroencephalography monitoring. We identified 68 patients (age range 1.9-18.1 years [median 6.9 years]; male to female ratio 1.3:1) treated with zonisamide for 0.7 to 28.9 months; at the last visit, 22% and 78% were on monotherapy and adjunctive therapy, respectively. The median duration of treatment and maintenance dose at the end of the follow-up were 11.2 months and 8.0 mg/kg/day, respectively. Seizure types included generalized (primary generalized tonic-clonic, myoclonic, tonic, atonic, absence) and partial (simple, complex, and secondarily generalized tonic-clonic seizures); 10 (15%) patients had both partial and generalized seizures. Sixteen (25.8%) patients were seizure free, although five of them were already in remission prior to starting zonisamide. Thirteen (21.0%) patients had a >= 50% seizure reduction, 10 (16.1%) patients had a < 50% seizure reduction, 14 (22.6%) had no improvement in baseline seizures, and 9 (14.5%) reported having increased seizures. The latter were mostly associated with dosage alterations in concomitant antiepileptic drugs. Common side effects were central nervous system related, including behavioral or psychiatric (23.5%), cognitive dysfunction (12.0%), and sedation (10.3%). Eleven (16.2%) patients ultimately discontinued zonisamide, but only five were strictly due to side effects. Zonisamide is clinically effective against multiple seizure types in a significant proportion of children with epilepsy across a broad age range. Drug discontinuation as a result of side effects is uncommon. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Synthesis and binding affinities of a series of 1,2-benzisoxazole-3-carboxamides to dopamine and serotonin receptors

A series of 1,2-benzisoxazole-3-carboxamides derived from tertiary cycloalkylamines was synthesized and evaluated for affinity for serotonergic (5-HT3 and 5-HT4) and dopaminergic (D-2) receptors using radioligand binding assays. The majority of compounds displayed a very weak affinity for the studied neurotransmitter receptors. Only amides containing a conformationally rigid system retained a relative 5-HT3 receptor affinity. The presence of a quinuclidine group affected receptor interaction more favorably than the tropane framework.

SYNTHESIS OF HYDROPHOBICALLY AND ELECTROSTATICALLY MODIFIED POLYACRYLAMIDES AND THEIR CATALYTIC EFFECTS ON THE UNIMOLECULAR DECARBOXYLATION OF 6-NITROBENZISOXAZOLE-3-CARBOXYLATE ANION

A series of hydrophobically and electrostatically modified polyacrylamides (Copol(AM-C12)) has been synthesized by radical-initiated copolymerization of acrylamide with n-dodecylmethyldiallylammonium bromide as the hydrophobe in aqueous solution using ammonium persulfate as the initiator. The formation of hydrophobic microdomains of the copolymers was revealed by large hypsochromic shifts of the long-wavelength absorption band of the solvatochromic probe Methyl Orange, noncovalently bound to the macromolecule. It was found that the microdomains formed by these copolymers in aqueous solution are more hydrophobic than those of the cationic polysoaps poly(alkylmethyldiallylammonium halides) containing the same n-dodecyl groups as the side chains as a result of the reduced electrostatic repulsions at the periphery of the microdomains. The reduced cationic character of the copolymers Copol(AM-C12) most likely also accounts for the observation that the anionic dye Methyl Orange does not; induce microdomain formation in aqueous solution. The effect of the hydrophobically and electrostatically modified polyacrylamides on the unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate anion (6-NBIC) has been investigated in aqueous solutions at pH 11.3 and 30 degrees C. It is suggested that the relatively modest catalytic effects induced by Copol(AM-C12) should be ascribed to hydrogen-bond stabilization of the initial state by NH groups in the macromolecules. The decarboxylation rates of 6-NBIC at binding sites in hydrophobic microdomains increase with increasing n-dodecyl group content in the copolymers.
