In this study, we compared the anticonvulsive effects of zonisamide (ZNS) with those of phenytoin (PHT), carbamazepine (CBZ) and phenobarbital (PB) in amygdaloid (AM)-kindled rats. Electrodes were implanted into the left AM of adult male Wistar rats. The animals were kindled at the afterdischarge (AD) threshold. After the completion of kindling, the generalized seizure triggering threshold was determined. The drugs were administered intraperitoneally in animals that showed stable generalized convulsions at near-threshold stimulation. Immediately after each drug trial, venous blood was sampled and the serum drug concentration was measured using EMIT or HPLC. All the drugs suppressed secondary generalization at lower doses, and further regressed the seizure stage and reduced the AD duration at higher doses. Higher doses of all drugs except ZNS, however, produced motor ataxia or lethargy. Thus, ZNS seemed to have a wider therapeutic range than other conventional antiepileptic drugs. An additional experiment on the effects of ZNS against supra-threshold stimulation suggested that a major action of ZNS in the kindling model is to attenuate the seizure spread rather than to elevate the AD threshold at the focus.

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 52356-01-1, in my other articles.

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. 625-08-1, Name is 3-Hydroxy-3-methylbutanoic acid, SMILES is CC(C)(O)CC(O)=O, in an article , author is Dolder, Christian, once mentioned of 625-08-1, Synthetic Route of 625-08-1.

Purpose. The efficacy, safety, pharmacology, pharmacokinetics, drug-drug interactions, and administration of paliperidone for schizophrenia are reviewed. Summary. Paliperidone is a benzisoxazole derivative and the principal active metabolite of risperidone. Representative of most oxidative metabolites, paliperidone is less lipophilic than risperidone. Like other atypical antipsychotics, paliperidone has a greater affinity for serotonin type 2A-receptor blockade relative to dopamine type 2-receptor blockade. Paliperidone’s advanced-gene ration osmotic release delivery system allows for the avoidance of dosage adjustment when initiating therapy and may decrease the frequency of antidopaminergic effects that would occur with an immediate-release formulation. The pharmacologic actions of paliperidone are similar to other high potency atypical antipsychotics. The receptor-binding profile of paliperidone most closely resembles that of risperidone and ziprasidone. Paliperidone differs from risperidone and most other antipsychotics by its relatively low extent of enzymatic metabolism. A limited number of investigations have demonstrated the ability of paliperidone to produce significant improvements in psychopathology, functioning, and relapse in patients with schizophrenia when compared with placebo. Paliperidone appears to have a similar adverse-effect profile compared to risperidone, except for an increased rate of hyperprolactinemia. The recommended dose of paliperidone for the treatment of adults with schizophrenia is 6 mg every morning. Conclusion. Paliperidone does not offer any clear advantage over other atypical antipsychotics with a similar receptor-binding profile, such as risperidone and ziprasidone. Nevertheless, a few investigations have demonstrated the ability of paliperidone to produce significant improvements in psychopathology, functioning, and relapse when compared with placebo. Based on limited studies, the frequency of adverse effects, except for hyperprolactinemia, appears to favor paliperidone over risperidone.

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.

In a document, author is Sugihara, K, introducing its new discovery. Category: Benzisoxazole.

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide) an anticonvulsant agent, is primarily metabolized to 2-sulfamoylacetyl-phenol by reductive cleavage of the 1,2-benzisoxazole ring. Rabbit liver cytosol with an electron donor of aldehyde oxidase exhibited a significant zonisamide reductase activity that was sensitive to inhibition by menadione, an inhibitor of aldehyde oxidase, The result suggested that the cytosolic activity is caused by aldehyde oxidase, a cytosolic enzyme. In fact, rabbit and rat liver aldehyde oxidase had the ability to reduce zonisamide when supplemented with its electron donor, Apparent K-M and V-max values of aldehyde oxidase for zonisamide were 217 mu M and 42 nmol/10 min/mg protein in the case of the rabbit liver enzyme, and 542 mu M and 382 nmol/10 min/mg protein in the case of the rat liver enzyme, respectively. In rabbits, hamsters, mice, and guinea pigs, zonisamide reductase activity of the liver cytosols with 2-hydroxypyrimidine, an electron donor of aldehyde oxidase, was much higher than that of the liver microsomes with NADPH. In rats, zonisamide reductase activity was examined with liver microsomes and cytosols from seven strains. The 2-hydroxypyrimidine-dependent cytosolic activity exhibited marked strain differences, unlike the NADPH-dependent microsomal activity, 1,2-Benzisoxazole was also reduced to salicylaldehyde by rabbit liver cytosol and aldehyde oxidase in the presence of 2-hydroxypyrimidine, Stoichiometric studies showed that 2-sulfamoylacetylphenol was formed accompanying nearly equimolar ammonia from zonisamide.

The acid/base-catalysed Kemp elimination of 5-nitro-benzisoxazole forming 2-cyano-4-nitrophenol has long served as a design platform of enzymes with non-natural reactions, providing new mechanistic insights in protein science. Here we describe an alternative concept based on redox catalysis by P450-BM3, leading to the same Kemp product via a fundamentally different mechanism. QM/MM computations show that it involves coordination of the substrate’s N-atom to haem-Fe(II) with electron transfer and concomitant N-O heterolysis liberating an intermediate having a nitrogen radical moiety Fe(III)-N-center dot and a phenoxyl anion. Product formation occurs by bond rotation and H-transfer. Two rationally chosen point mutations cause a notable increase in activity. The results shed light on the prevailing mechanistic uncertainties in human P450-catalysed metabolism of the immunomodulatory drug leflunomide, which likewise undergoes redox-mediated Kemp elimination by P450-BM3. Other isoxazole-based pharmaceuticals are probably also metabolized by a redox mechanism. Our work provides a basis for designing future artificial enzymes.

With the eventual goal of making zonisamide (ZNS), a relatively new antiepileptic drug, available for the treatment of epilepsy in cats, the pharmacokinetics after a single oral administration at 10 mg/kg and the toxicity after 9-week daily administration of 20 mg/kg/day of ZNS were Studied in healthy cats. Pharmacokinetic parameters obtained with a single administration of ZNS at 10 mg/day were as follows: C-max = 13.1 mu g/ml; T-max = 4.0 h; T-1/2 = 33.0 h; areas under the curves (AUCs) – 720.3 mu g/ml h (values represent the medians). The Study with daily administrations revealed that the toxicity of ZNS was comparatively low in cats, suggesting that it may be an available drug for cats. However, half of the cats that were administered 20 mg/kg/day daily showed adverse reactions Such as anorexia, diarrhoea, vomiting, somnolence and locomotor ataxia.

Aripiprazole is a relatively novel second-generation antipsychotic belonging to the chemical class of benzisoxazole derivatives and is characterized by a unique pharmacological profile which suggests that the drug acts as a dopamine-serotonin system stabilizer. Whereas all previously available antipsychotics are antagonists at D-2 receptors, aripiprazole is the only available partial agonist at these receptors. Thus, it has been suggested that aripiprazole could be associated with a relatively neutral impact on bodyweight, possibly reducing risks of a detrimental impact on the quality of life that often complicates management for a large number of patients diagnosed with severe and persistent mental disorders (SPMDs) treated chronically with antipsychotic medications. However, data from short- and long-term reviewed studies indicate that the prevalence rate of clinically relevant weight gain during therapy with this drug is similar to that occurring during treatments with other antipsychotic agents, either typical or atypical. Moreover, information on the impact of aripiprazole therapy on the quality of life of patients diagnosed with SPMDs is scarce and characterized by conflicting results. Given these results, further, large, well-designed studies are needed before confirming potential advantages of aripiprazole over first-generation antipsychotics and other SGAs.
