Cocrystals of zonisamide: physicochemical characterization and sustained release solid forms

We report four cocrystals of the antiepileptic drug, zonisamide (ZNS), which encounters half-life fluctuation when administered adjunctly with other antiepileptic drugs. Single crystals for two of the novel cocrystals of ZNS were successfully prepared from solvent evaporation experiments and their crystal structures were determined. Pharmaceutically acceptable cocrystals were analyzed for their dissolution rate, solubility and stability to draw conclusions on the impact of cocrystallization on the physicochemical properties of ZNS. It was found that the cocrystals showed lower solubility and dissolution rates and offer potential benefits in the development of sustained release formulations of ZNS which could address issues regarding its half-life fluctuation. Recent attempts to explore newer therapeutic applications have suggested ZNS as a potential drug for weight loss management. In this regard, the cocrystal of ZNS with caffeine, which has also been used in weight loss management, promises potential applications in the development of a novel fixed-dose combination drug which could offer synergistic therapeutic benefits in the treatment of obesity.

Zonisamide: Review of its use in epilepsy therapy

Zonisamide is an antiepileptic drug used as adjunctive therapy for refractory partial seizures in adults. Because of the multiple mechanisms of action, it shows a broad spectrum of anticonvulsant activity and has been effective in several types of seizures, including partial and generalized seizures, tonic-clonic seizures and absence seizures in patients unresponsive to other anticonvulsants. Myoclonic epilepsy, Lennox-Gastaut syndrome and infantile spasms have also been treated effectively with zonisamide. Recent clinical studies have demonstrated additional potential for therapeutic use in neuropathic pain, bipolar disorder, migraine, obesity, eating disorders and Parkinson’s disease. Despite adverse events, zonisamide is relatively safe and well tolerated in patients, and shows low discontinuation rate. It has a good pharmacokinetic profile and a low drug interaction potential. Zonisamide is considered as a drug that effectively reduces the frequency of partial seizures. (C) 2005 Prous Science. All rights reserved.

SYNTHESIS AND CATALYTIC PROPERTIES OF NON-CROSS-LINKED AND CROSS-LINKED POLY(ALKYLMETHYLDIALLYLAMMONIUM BROMIDES) HAVING DECYL, OCTYL, AND HEXYL SIDE-CHAINS

A family of non-cross-linked and cross-linked copolymers containing decyl, octyl, and hexyl groups as side chains ((CL)-CopolC1-10, (CL)-CopolC1-8, and (CL)-CopolC1-6, respectively) were synthesized by radical-initiated cyclocopolymerization of alkylmethyldiallylammonium bromide monomers without and with a small amount of N,N’-methylenebisacrylamide as a cross-linking agent in aqueous solution. Their H-1 NMR and IR spectra indicated the presence of five-membered rings cross-linked without and with N,N’-methylenebisacrylamide in the macromolecules. Viscosity measurements showed that the cross-linked copolymers exhibit a larger reduced viscosity in aqueous solution with increasing cross-linking agent content in the copolymers. For(CL)-CopolC1-10, the conformational transition to compact coils was indicated by changes of the reduced viscosity in dilute aqueous solutions. At higher concentrations, intermolecular aggregation was also revealed and increased with increasing the percentage of cross-linking for CL-CopolC1-10. (CL)-CopolC1-8 and (CL)-CopolC1-6 showed extented molecular dimensions in aqueous solution. The hydrophobic microdomains of the non-cross-linked and cross-linked copolymers were probed by hypsochromic shifts of the long-wavelength absorption band of Methyl Orange as a solvatochromic agent, noncovalently bound to the macromolecule. The unimolecular decarboxylation of 6-nitrobenzisox-azole-3-carboxylate (6-NBIC), catalyzed by these copolymers in aqueous solution, was used as a model reaction to study the influence of polysoap microenviroment on reactivity. Depending on the hydrophobic group content, (CL)-CopolC1-10 led to a remarkably large rate enhancement, whereas (CL)-CopolC1-8 induced only modest rate acceleration for the decarboxylation of 6-NBIC. A small rate enhancement was observed in the presence of(CL)-CopolC1-6. The decarboxylation rate is also sensitive to changes of the percentage of cross-linking in the macromolecules. A maximum in rate constant was found at about 0.2% (w/w) cross-linking agent for CL-CopolC1-10 and at about 0.4% (w/w) for CL-CopolC1-8 in plots of the rate constant vs cross-linking agent content.

ZONISAMIDE: A NEW DRUG FOR PARKINSON’S DISEASE

Zonisamide, a benzisoxazole derivative, is an antiepileptic drug with a long half-life. Three nationwide, double-blind, placebo-controlled studies carried out in Japan prompted the approval of zonisamide as an antiparkinsonian agent in early 2009. The addition of zonisamide at 25-50 mg/day to currently used antiparkinsonian drugs significantly improved cardinal symptoms in patients with advanced Parkinson’s disease. The effects were maintained over more than 1 year even in patients with advanced disease. Zonisamide has multiple modes of action, and its effects on Parkinson’s disease include activation of dopamine synthesis, inhibition of monoamine oxidase, inhibition of T-type calcium channels and inhibition of an indirect pathway in the basal ganglia through the delta opioid receptor Furthermore, zonisamide exhibits neuroprotective effects in animal models of Parkinson’s disease. It strongly inhibits quinoprotein formation and markedly increases glutathione S-transferase levels in the striatum by enhancing the astroglial cysteine transport system and/or astroglial proliferation via S100 beta production and secretion.

Novel DNA Gyrase Inhibiting Spiropyrimidinetriones with a Benzisoxazole Scaffold: SAR and in Vivo Characterization

The compounds described herein with a spirocyclic architecture fused to a benzisoxazole ring represent a new class of antibacterial agents that operate by inhibition of DNA gyrase as corroborated in an enzyme assay and by the inhibition of precursor thymidine into DNA during cell growth. Activity resided in the configurationally lowest energy (2S,4R,4aR) diastereomer. Highly active compounds against Staphylococcus aureus had sufficiently high solubility, high plasma protein free fraction, and favorable pharmacokinetics to suggest that in vivo efficacy could be demonstrated, which was realized with compound (-)-1 in S. aureus mouse infection models. A high drug exposure NOEL on oral dosing in the rat suggested that a high therapeutic margin could be achieved. Importantly, (-)-1 was not cross-resistant with other DNA gyrase inhibitors such as fluoroquinolone and aminocoumarin antibacterials. Hence, this class shows considerable promise for the treatment of infections caused by multidrug resistant bacteria, including S. aureus.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 79-14-1, you can contact me at any time and look forward to more communication. Application In Synthesis of 2-Hydroxyacetic acid.

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.
