THE 1ST OPEN STUDY OF ZONISAMIDE, A NOVEL ANTICONVULSANT, SHOWS EFFICACY IN MANIA

1 Zonisamide, an anticonvulsant developed in Japan, is structurally similar to serotonin. Zonisamide has been proven to have a pharmacological profile that is very similar to that of carbamazepine. Thus, the effect of zonisamide was examined in 24 psychiatric patients: 15 with bipolar manic state, 6 with schizoaffective manic state, and 3 schizophrenic excitement. 2 Approximately 25% of all the patients and 33% of the bipolar manic patients showed remarkable global improvement with the addition of zonisamide. Approximately 71% of all the patients and 80% of the bipolar group had more than moderate global improvement. 3 No serious adverse reactions were found and no patients required zonisamide withdrawal. One patient developed both leukocytosis and mildly abnormal liver function test. One developed leukocytosis and another reported mild sleepiness. These reactions disappeared when zonisamide was discontinued.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 503-74-2 help many people in the next few years. Quality Control of 3-Methylbutanoic acid.

SYNTHESIS AND EVALUATION OF A SERIES OF 3,5-DISUBSTITUTED BENZISOXAZOLE-4,7-DIONES – POTENT RADIOSENSITIZERS INVITRO

A series of 3,5-disubstituted-2,1-benzisoxazole-4,7-diones was synthesized and evaluated as radiosensitizers both in vitro and in vivo. These compounds were designed as non-nitro electron-affinic agents in an effort to alleviate some of the toxicities seen with the 2-nitroimidazole radiosensitizers evaluated in the clinic. Several compounds in this series were potent radiosensitizers in vitro, with sensitizer enhancement ratios of 2.0-2.3 at concentrations < 0.5 mM. Compounds with potent in vitro activity were also evaluated in vivo. However, none of these compounds showed radiosensitizing activity in vivo. The reduction potentials of these compounds were determined by cyclic voltammetry and compared to other electron-affinic radiosensitizers. In general, the reduction potentials of this series of compounds was slightly more positive than the 2-nitroimidazoles, but they fell within the range postulated as acceptable to yield in vivo activity. The results suggest that factors other than reduction potential may be responsible for the lack of in vivo radiosensitizing activity observed for this class of radiosensitizers. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 5117-19-1 help many people in the next few years.

ACTIVITY OF 1,2-BENZISOXAZOLE-3-ONE AND INDOLE-2,3-DIONE ON PLANT-REGENERATION INVITRO AND ON CELL ELONGATION

We tested the morphogenetic and cell elongating activity of 1,2-benzisoxazole-3-one, a compound similar to 1,2-benzisoxazole-3-acetic acid but lacking the lateral carbon chain. For comparison, we tested also the activity of indole-2,3-dione, having the same indolic ring as indole-3-acetic acid but no lateral carbon chain. The tests were made on the regeneration of tomato (Lycopersicon esculentum Miller var. Alice) from cotyledons and on pea (Pisum sativum L. var. Alaska) stem elongation. We found that 1,2-benzisoxazole-3-one retains part of the high shoot inducing activity of 1,2-benzisoxazole-3-acetic acid, while indole-2,3-dione is inactive. Both compounds have no effect on root induction or cell elongation. It seems therefore that the activity of 1,2-benzisoxazole-3-acetic acid is partly related to the structure of its ring, and that also in this respect 1,2-benzisoxazole-3-acetic acid differs from other auxin-like compounds.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2836-32-0 is helpful to your research. Application In Synthesis of Sodium glycolate.

DFT STUDY OF THE PROTONATION AND DEPROTONATION ENTHALPIES OF BENZOXAZOLE, 1,2-BENZISOXAZOLE AND 2,1-BENZISOXAZOLE AND IMPLICATIONS FOR THE STRUCTURES AND ENERGIES OF THEIR ADDUCTS WITH EXPLICIT WATER MOLECULES

Benzoxazole, 1,2-benzisoxazole and 2,1-benzisoxazole are biologically active molecules with potential applications in drug design. Their interaction with aqueous medium in biological systems may be simulated by considering their interaction with explicit water molecules. Such studies provide information on the structures, energies and type of interactions stabilizing the resulting geometric systems. The objective of the current study was to utilize theoretical approaches to investigate the structures, stabilization energy and binding energy of benzox-azole-water, 1,2-benzisoxazole-water and 2,1-benzisoxazole-water complexes. The calculations were performed utilizing the density functional theory (DFT)/M06-2X/6-311++G(d, p) method and the DFT/omega B97XD method with both the 6-311++G(d, p) and the aug-cc-pVDZ basis sets. The results suggest that the stability of the different clusters depends on interrelated factors including the rings formed by intermolecular hydrogen bonds and the proton affinity (PA) or acidity of the atoms forming the intermolecular hydrogen bonds with the water molecules. A comparison across methods indicates that the results follow similar trends with different methods.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 815-17-8. The above is the message from the blog manager. Category: Benzisoxazole.

Activation by zonisamide, a newer antiepileptic drug, of large-conductance calcium-activated potassium channel in differentiated hippocampal neuron-derived H19-7 cells

Zonisamide (ZNS; 3-sulfamoylmethyl-1,2-benzisoxazole), as one of the newer antiepileptic drugs, has been demonstrated its broad-spectrum clinical efficacy on various neuropsychiatric disorders. However, little is known regarding the mechanism of ZNS actions on ion currents in neurons. We thus investigated its effect on ion currents in differentiated hippocampal 19-7 cells. In whole-cell configuration of patch-clamp technology, the ZNS (30 mu M) reversibly increased the amplitude of K+ outward currents, and paxilline (1 mu M) was effective in suppressing the ZNS-induced increase of K+ outward currents. In inside-out configuration, ZNS (30 mu M) applied to the intracellular face of the membrane did not alter single-channel conductance; however, it did enhance the activity of large-conductance Ca2+-activated K+ (BKCa) channels primarily by decreasing mean closed time. In addition, the EC50 value for ZNS-stimulated BK Ca channels was 34 mu M. This drug caused a left shift in the activation curve of BK Ca channels, with no change in the gating charge of these channels. Moreover, ZNS at a concentration greater than 100 mu M also reduced the amplitude of A-type K+ current in these cells. A simulation modeling based on hippocampal CA3 pyramidal neurons (Pinsky-Rinzel model) was also analyzed to investigate the inhibitory effect of ZNS on the firing of simulated action potentials. Taken together, this study suggests that, in hippocampal neurons during the exposure to ZNS, the ZNS-mediated effects on BK Ca channels and A-type K+ current could be potential mechanisms through which it affects neuronal excitability.

Low-Dose Risperidone-Induced Facial Edema in a Child with Conduct Disorder

Risperidone, a benzisoxazole derivate, is a widely prescribed antipsychotic agent that binds with high affinity to dopamine D2, serotonin type 2 (5-HT2) and al-adrenergic receptors, and causes antagonism at these receptor sites. Although risperidone has several side effects such as weight gain and sedation, edema is a very rarely observed side effect in children and adolescents. Here, we report a case of facial edema in a child with conduct disorder (CD) who was receiving low-dose of oral solution risperidone. Three days after risperidone discontinuation, the facial edema resolved entirely. Because a plausible mechanism of risperidone-induced edema remains unknown, further investigation is warranted to elucidate the risk factors and potential mechanisms of the edema.

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 181289-15-6, in my other articles.

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.

Process improvements for the preparation of kilo quantities of a series of isoindoline compounds

A series of isoindoline analogues with either an indazole (HMR 2934, HMR 2651) or benzisoxazole (HMR 2543) appendage were prepared for the proposed treatment of psychiatric disorders such as obsessive compulsive disorder and attention deficit disorder. The isoindoline compounds were prepared by reduction of the corresponding phthalimides with LiAlH4. One compound was not chiral, and the other two required an enantioselective synthesis. The key step for these optically active analogues involved the coupling by an S(N)2 process of either a piperazynyl intermediate or a piperdinyl intermediate with methyl 3-benzyloxy-2-trifluoromethansulfonatopropionate. The products for these two analogues had >98% ee. Process improvements led to the multi-kilogram syntheses of each of these compounds.

Zonisamide: A Review of Its Use in the Management of Adults with Partial Seizures

Oral zonisamide (Zonegran (R)) is a benzisoxazole derivative chemically unrelated to other antiepileptic agents. It is indicated in the EU as monotherapy in the treatment of partial seizures, with or without secondary generalization, in adults with newly diagnosed epilepsy and as adjunctive therapy to other antiepileptic drugs (AEDs) in the treatment of adults with partial seizures, with or without secondary generalization. In a double-blind, multinational study in adults newly diagnosed with partial seizures, shorter-term monotherapy with once-daily zonisamide was noninferior to that with twice-daily carbamazepine controlled release in terms of seizure freedom according to the International League Against Epilepsy guidelines, with seizure freedom benefits maintained during longer-term therapy. In four randomized, double-blind, placebo-controlled studies in adults with refractory partial seizures, shorter-term adjunctive therapy with once-or twice-daily zonisamide reduced the frequency of seizures to a significantly greater extent than placebo, with antiepileptic efficacy sustained following longer-term treatment in this patient population. Zonisamide was generally well tolerated in adults with partial seizures participating in these studies, with the majority of adverse events being mild or moderate in severity. Thus, oral zonisamide as monotherapy or adjunctive therapy to other AEDs provides a useful option in the treatment of patients with partial seizures.
