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. 929-59-9, Name is 1,2-Bis(2-aminoethoxy)ethane, SMILES is NCCOCCOCCN, in an article , author is SATO, H, once mentioned of 929-59-9, Application In Synthesis of 1,2-Bis(2-aminoethoxy)ethane.

A series of substituted 7,8-dihydrofuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acids 9 and 7,8-dihydrofuro[2,3-g]benzoxazole-7-carboxylic acids 12 were synthesized and evaluated for uricosuric and diuretic activities in rats. Many of the benzisoxazole derivatives 9 showed uricosuric and only weak diuretic activities, whereas the benzoxazoles 12 exhibited potent diuretic activities with little affecting urate excretion. Among these compounds, 5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid (9b, AA-193) was found to be a potent uricosuric agent without diuretic activity and was selected for further development.

Objectives: Zonisamide (1,2-benzisoxazole-3-methanesulfonamide) is a novel antiseizure medication approved for use in the United States as adjunct therapy in the treatment of partial seizures in adults with epilepsy. It has also been used to treat other conditions including intractable pain. The aim of this study was to determine the usefulness of zonisamide in patients whose seizures were not controlled after having been treated with at least three other currently available anticonvulsant medications or in patients whose pain control was suboptimal despite the use of commonly used drug regimens. Methods: This was a retrospective study documenting the efficacy of zonisamide in 48 consecutive patients who presented at an outpatient neurology clinic at a Veterans Administration hospital. The patients were diagnosed with refractory partial seizures (n = 21) or a variety of intractable neuropathic pain syndromes (n = 27). Results: Sixteen out of 21 seizure patients (76%) experienced a 50% or greater reduction in seizure frequency when zonisamide (1100-200 mg daily) was added to their existing anticonvulsant medication regimen. Of 27 patients with neuropathic pain, 17 (59%) responded to zonisamide, reporting subjective reduction in pain by at least 50%. The most common adverse events were gastrointestinal upset, somnolence, and one case of skin rash. Conclusions: In this study, zonisamide appeared to be an effective adjunct therapy in the treatment of partial seizures in adults who continued to experience frequent episodes while taking other anticonvulsant medications, and in adults whose neuropathic pain was not well controlled with analgesics. These promising results must be tempered by the fact that this investigation included a small patient population in an uncontrolled study design. Further research into the efficacy and tolerability of zonisamide in these areas is warranted.

Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. 123-99-9, Name is Water-soluble azelaic acid, molecular formula is C9H16O4, Name: Water-soluble azelaic acid, belongs to benzisoxazole compound, is a common compound. In a patnet, author is Mares, Pavel, once mentioned the new application about 123-99-9.

Zonisamide is increasingly used in pediatric neurology but there are no experimental data for immature animals. Zonisamide (12.5-100 mg/kg i.p.) was tested against pentetrazol-induced seizures in 7-, 12-, 18-, 25- and 90-day-old rats. Minimal clonic seizures were not suppressed by zonisamide. Selective suppression of tonic phase of generalized tonic-clonic seizures was demonstrated in all age groups. This effect indicates possible action of zonisamide against generalized tonic-clonic seizures during brain maturation. (C) 2010 Published by Elsevier B.V.

Quetiapine fumarate (QTF) is an antipsychotic drug belonging to the benzisoxazole derivatives indicated for the treatment of schizophrenia. A sensitive and selective method based on dichloromethane-extractable ion-pair of QTF with calmagite (CGT), which exhibited an absorption maximum at 490 nm, is described. At this. wavelength, Beer’s law is obeyed over the concentration range of 3.0-30.0 mu g ml(1). The apparent molar absorptivity, limit of detection (L OD) and quantitation (LOQ) values are 1.32×10(4) I mol(1) cm(-1), 0.27 and 0.81 mu g ml(1), respectively. The reaction is extremely rapid at room temperature and the absorbance values remain unchanged up to 19 h. The precision results, expressed as intra-day and inter-day relative standard deviation values, are satisfactory (RSD <= 2.2%). The accuracy is satisfactory as well (RE <= 2.44%). The method was successfully applied to the determination of QTF in pharmaceuticals and spiked human urine with satisfactory results. No interference was observed from common pharmaceutical adjuvants in tablets. Statistical comparison of the results with the official method showed an excellent agreement and indicated no significant difference in precision.

Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. 526-83-0, Name is 2,3-Dihydroxysuccinic acid, SMILES is O=C(O)C(O)C(O)C(O)=O, in an article , author is Hotta, K, once mentioned of 526-83-0, Electric Literature of 526-83-0.

Monoclonal antibodies were generated against a 3-phenyl-1,2-benzisoxazole derivative and shown to catalyze the solvent-sensitive decarboxylation of 3-carboxy-1,2-benzisoxazoles. In addition to rare accelerations up to 2300-fold over background, the antibodies exhibit distinctive selectivities for substrates bearing 5- or 6-NO2 substituents, with preferential decarboxylation of the less reactive substrate in one case. These effects are the likely consequence of substrate destabilization, achieved by forcing the carboxylate group into a relatively apolar binding pocket and stabilization of the charge-delocalized transition state through dispersive interactions. Comparison with a more active antibody decarboxylase previously raised against 2-acetamido-naphthalene-1,5-disulfonate suggests, however, that a judicious mix of polar and apolar interactions may ultimately be more effective for achieving high decarboxylase activity.

Electric Literature of 526-83-0, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 526-83-0.

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.

While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards.6108-17-4, Name is Lithium acetate dihydrate, SMILES is CC([O-])=O.[H]O[H].[H]O[H].[Li+], in an article , author is Hamada, K, once mentioned of 6108-17-4, Name: Lithium acetate dihydrate.

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.
