Zonisamide: A Review of Its Use as Adjunctive Therapy in the Management of Partial Seizures in Pediatric Patients Aged >= 6 Years

Oral zonisamide (Zonegran(A (R))) is a benzisoxazole derivative chemically unrelated to other antiepileptic drugs (AEDs). It is approved in the EU as an adjunct to other AEDs in the treatment of pediatric patients aged a parts per thousand yen6 years with partial seizures, with or without secondary generalization. In a randomized, double-blind, multinational, phase III study in pediatric patients aged 6-17 years with partial seizures, the proportion of patients achieving a a parts per thousand yen50 % reduction from baseline in seizure frequency per 28 days during the maintenance treatment period was significantly higher with adjunctive therapy with zonisamide than placebo. The antiepileptic efficacy of zonisamide was sustained during a 59-week extension study in this patient population. Zonisamide was generally well tolerated in these studies, with the majority of adverse events being mild or moderate in severity. Thus, oral zonisamide as an adjunctive therapy to other AEDs provides a useful option in the treatment of pediatric patients aged a parts per thousand yen6 years with partial seizures.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 79-14-1, in my other articles.

Carbonic anhydrase inhibitors. Zonisamide is an effective inhibitor of the cytosolic isozyme II and mitochondrial isozyme V: solution and X-ray crystallographic studies

The antiepileptic drug zonisamide was considered to act as a weak inhibitor of the zinc enzyme carbonic anhydrase (CA, EC 4.2. 1.1) (with a K, of 4.3 mu M against the cytosolic isozyme 11). Here we prove that this is not true. Indeed, testing zonisamide in the classical assay conditions of the CO2 hydrase activity of hCA II, with incubation times of enzyme and inhibitor solution of 15 min, a K-1 of 10.3 mu M has been obtained. However, when the incubation between enzyme and inhibitor was prolonged to 1d h, the obtained K-1 was of 35.2 nM, of the same order of magnitude as that of the clinically used sulfonamides/sulfamates acetazolantide, methazolamide, ethoxzolamide and topiramate (K(1)s in the range of 5.4-15.4 nM). The inhibition of the human mitochondrial isozyme hCA V with these compounds has been also tested by means of a dansylamide competition binding assay, which showed zonisamide and topiramate to be effective inhibitors, with K(1)s in the range of 20.6-25.4 nM. The X-ray crystal structure of the adduct of hCA 11 with zonisamide has also been solved at a resolution of 1.70 A, showing that the sulfonamide moiety participates in the classical interactions with the Zn(II) ion and the residues Thr199 and Glu106, whereas the benzisoxazole ring, is oriented toward the hydrophobic half of the active site, establishing a large number of strong van der Waals interactions (< 4.5 A) with residues Gln92, Vall2l, Phe131, Leu198, Thr200, Pro202.

An unusual case of risperidone instability in a fatality presenting an analytical and interpretative challenge

This paper describes the detection and characterization of unusual metabolite/breakdown products of the anti-psychotic drug risperidone in post-mortem blood and urine as part of a toxicological investigation into an unexpected death of a male suffering from paranoid schizophrenia prescribed risperidone and previously paroxetine. Compounds detected in the post-mortem blood and urine specimens were shown to be benzisoxazole ring scission products of risperidone and a hydroxy metabolite. These compounds are never routinely detected in blood and urine but can be present in mammalian faeces indicating that gut bacteria could be responsible for their formation. In this case, evidence for this process was demonstrated by the controlled in vitro stability study of risperidone spiked into the case blood and urine leading to the hypothesis that the post-mortem blood and urine samples analyzed could have contained bacteria with the ability to breakdown risperidone and its metabolite in this way. This finding is very unusual and has not been encountered before in any previous risperidone cases investigated by the authors, or widely reported in the post-mortem toxicological literature. However, a recently published paper has supported these findings in blood. As a result of this work, it was shown that the deceased had taken risperidone prior to death, even in the absence of any risperidone or its hydroxy metabolite(s) in the blood and urine. Given that risperidone has been reported to interact with paroxetine, the ingestion of risperidone could have been a factor that contributed to the death. Copyright (c) 2013 John Wiley & Sons, Ltd.

Effects of zonisamide on dopaminergic system

Effects of zonisamide (ZNS) on extracellular dopamine (DA), its precursor 3,4-dihydroxyphenylalanine (DOPA), its metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) levels in the striatum as well as hippocampus of freely moving rats were studied. Intracellular DA, DOPA, DOPAC and HVA levels, as well as DOPA accumulation as an index of tyrosine hydroxylase activity in the rat brain in vivo, DA re-uptake in the striatum and hippocampus, and monoamine oxidase (MAO) activities were also determined. Acute administrations of therapeutic ZNS doses (20 and 50 mg/kg) increased striatal extracellular DOPA levels, intracellular striatal and hippocampal DOPA levels, and stimulated DOPA accumulation in both brain regions. ZNS also increased striatal and hippocampal intracellular as well as extracellular DA and MIA Levels, but decreased those of DOPAC levels. Chronic (3 weeks) administrations of therapeutic ZNS doses (20 and 50 mg/kg/day) increased intracellular DA, DOPA, DOPAC and HVA levels in striatum and hippocampus. ZNS-induced changes were greater in intracellular levels than in extracellular levels. Acute and chronic supratherapeutic ZNS dose (100 mg/kg) administration decreased intracellular levels of all substances detectable in both brain regions, and inhibited DOPA accumulation. Both subtypes of MAO (type A and type B) activities were weakly inhibited by ZNS. ZNS showed no effect on DA re-uptake in striatum nor in hippocampus. These results suggest that therapeutic ZNS doses increase DOPA accumulation as well as both intracellular and extracellular DA, DOPA and HVA levels. However, such doses also decrease extracellular and intracellular DOPAC levels by enhancing DA synthesis and/or by selectively inhibiting MAO-B activities. In addition, chronic therapeutic ZNS dose administration enhances DA synthesis, which results in increased intracellular DA, its precursor and its metabolites levels. On the other hand, both acute and chronic supratherapeutic ZNS dose administrations inhibit DA turnover. These ZNS effects on DA metabolism are at least partly involved in the mechanisms of action of ZNS.

Design and synthesis of amino acids-conjugated heterocycle derived ureas/thioureas as potent inhibitors of protein glycation

Protein glycation is believed to play an important role in the development of long-term disorders associated with diabetic complications. In view of the wide occurrence of advanced glycation end products (AGE’s) and the oxidative stress derived from them in a variety of diabetic complications, it would be of great interest to identify and develop AGE inhibitors. In this study, synthesis and in vitro antiglycation activity of a small library of forty urea/thiourea derivatives of Phe/Tyr/Glu/Lys-benzisoxazole hybrids are reported. Structures of the compounds were confirmed by IR, NMR, mass spectrometry, and elemental analysis. Most of the title compounds exhibited promising activity. Best antiglycation activity was found for Tyr analogue with methoxy group as a substituent particularly at the para position with IC50 value of 1.9 mu M against the positive control, Rutin, with IC50 = 41.9 mu M. Thus, the title compounds represent novel class of potent antiglycating agents.

A STAGE-SPECIFIC BLOCK IS PRODUCED IN CARROT SOMATIC EMBRYOS BY 1,2-BENZISOXAZOLE-3-ACETIC ACID

1,2-Benz-isoxazol-3-acetic acid is slightly toxic to unorganized growing carrot cells and completely prevents somatic embryogenesis beyond the globular stage. Its action is time dependent: if added early, it affects the determination of the early stages; if added later, after determination has occurred, it has practically no effect. The blocked forms can evolve, in the presence of the compound, creating secondary embryos that, in turn, are arrested at the globular stage. Since the secondary embryos adhere to the primary ones, irregular polyembryonic masses of typical appearance are created. The internal structures of the blocked globular embryos were examined and were shown to be enlarged, vacuolized and detached from the central cells. The protoderm also displayed an altered appearance. These data, when considered together with the effects of the compound on rooting and callus formation, suggest that benz-isoxazol acetic acid acts as a weak auxin.

Expedient synthesis of a novel class of pseudoaromatic amino acids: tetrahydroindazol-3-yl- and tetrahydrobenzisoxazol-3-ylalanine derivatives

A concise synthesis of novel homochiral aromatic amino acid surrogates comprising a tetrahydroindazole or a benzisoxazole system was developed via the acylation of a cyclic 1,3-diketone by the side-chain carboxyl functionality of either Boc-Asp-OtBu or Boc-Glu-OtBu followed by regioselective condensation with hydrazine, N-benzylhydrazine and hydroxylamine. The tetrahydroindazole nucleus was also constructed by the condensation of Boc-Asp-OtBu with the enamine, 1-pyrrolidino-1-cyclohexene followed by acid-hydrolytic treatment and reaction with hydrazines. Further functional group transformations gave N-alpha-Fmoc-protected derivatives as useful building blocks for solid-phase peptide assembly. (C) 2003 Elsevier Ltd. All rights reserved.
