Surface-enhanced Raman spectrum of anthranil (2,1-benzisoxazole) in activated silver colloid was recorded and compared with the conventional Raman spectrum. The experimentally observed Raman bands along with their corresponding infrared bands were assigned based on the results of density functional theory (DFT) calculations. The significant changes evidenced between the SER and normal Raman spectra combined with the theoretical data obtained for Ag-anthranil model systems demonstrated that this molecule is adsorbed on the colloidal silver particles through the lone pair electrons of the nitrogen atom. The contribution of the chemical mechanism to the SERS enhancement was proved by the behavior of the electronic absorption spectrum of the mixture of activated silver colloid and anthranil solution. The orientation of the adsorbed species with respect to the metal surface was also predicted.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 99189-60-3, you can contact me at any time and look forward to more communication. Name: 2-[1-(2-Amino-2-oxoethyl)cyclohexyl]acetic Acid.

Chemical Research Letters, May 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. In an article, author is Millan, MJ, once mentioned the application of 6106-21-4, Name is Sodium succinate hexahydrate, molecular formula is C4H16Na2O10, molecular weight is 270.1434, MDL number is MFCD00149117, category is benzisoxazole. Now introduce a scientific discovery about this category, Name: Sodium succinate hexahydrate.

The novel benzodioxopyrrolidine (S-16924) displays a clozapine-like profile of interaction with multiple monoaminergic receptors, in addition to potent agonist activity at serotonin (5-HT)(1A) receptors. S-16924 (2.5 mg/kg i.p.) and clozapine (5.0 mg/kg i.p.) generated robust discriminative stimuli (DS) and displayed full mutual generalization. The D-4 antagonists L-745,870 and S-18126, the D-1/D-5 antagonist SCH-39166, and the D-3 antagonist S-14297 showed at most partial generalization to S-16924 and clozapine. The D-2/D-3 antagonist raclopride fully generalized to S-16924, but only partially generalized to clozapine. The 5-HT2A antagonist MDL-100,907 fully generalized to S-16924 and two further 5-HT2A antagonists, fananserin and SR-46349, showed partial generalization. However, MDL-100,907, fananserin, and SR-46349 showed less pronounced generalization to clozapine. Similarly, the 5-HT2C antagonists SB-200,646 and SB-206,553 more markedly generalized to S-16924 than to clozapine. The 5-HT1A receptor agonist (+/-)-8-dihydroxy-2-(di-n-propylamino) tetralin generalized fully to S-16924 but not to clozapine. Full generalization was obtained to both S-16924 and clozapine for the clozapine congeners, olanzapine and quetiapine. In distinction, the benzisoxazole, risperidone, and the phenylindole, sertindole, weakly generalized to S-16924 and clozapine. However, the benzisoxazole ziprasidone, which possesses 5-HT1A agonist properties, generalized fully to S-16924 but not to clozapine. Finally, the muscarinic antagonist scopolamine generalized fully to clozapine and partially to S-16924. In conclusion, S-16924 and clozapine display both communalities and differences in their compound DS; this likely reflects their respective complex patterns of interaction with multiple monoaminergic receptors. Although no specific receptor was identified as underlying the clozapine DS, 5-HT1A agonist as well as D-2 and 5-HT2A/2C antagonist properties contribute to the S-16924 DS.

Zonisamide is an orally administered antiepileptic drug that was first approved for clinical use in Japan in 1989. Since then, it has been licensed in Korea for a broad spectrum of epilepsies in adults and children, and in the USA for adjunctive therapy of adults with partial seizures, and in Europe for monotherapy of adults with newly diagnosed partial seizures and adjunctive therapy of adults and adolescents and children aged 6years with partial seizures with or without secondary generalization. Zonisamide is a benzisoxazole derivative with a unique chemical structure, predictable dose-dependent pharmacokinetics, and multiple complementary mechanisms of action. Treatment with zonisamide is well tolerated and is not known to be associated with clinically significant drug-drug interactions, including with oral contraceptives or other antiepileptic drugs. There have been >2million patient-years of experience with zonisamide for treatment of epilepsy, and this drug has International League Against Epilepsy level A evidence for efficacy/effectiveness as initial monotherapy for adults with partial-onset seizures. This review presents the evidence for zonisamide across the spectrum of epilepsy, with emphasis on real-world clinical practice and special populations of patients (children, elderly patients, and women of childbearing age) who are likely to be treated in daily clinical practice.

In a document, author is Hoy, Sheridan M..

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.

A selective and sensitive liquid chromatographic method was developed for the determination of zonisamide in small volumes of plasma. Zonisamide and the internal standard methyl 4-hydroxybenzoate were extracted from 0.2 mL. of plasma with solid-phase extraction columns and eluted with methanol. Analysis of the extracts was performed on a Symmetry C-18 column with ultra-violet spectrophotometric detection. The calibration curve was linear over the concentration range of 0.05-5 mug mL(-1) in plasma. Recoveries were reasonable for routine analyses; the limit of quantification was 0.05 mug mL(-1) with a signal-to-noise ratio of 5. This method could be useful for the pharmacokinetic study of zonisamide in a limited volume of human plasma and for therapeutic drug monitoring.

Structure elucidation of compounds in the benzisoxazole series (1-6) and naphtho[1,2-d][1,3] (7-10) and phenanthro[9,10-d][1,3]oxazole (11-14) series was accomplished using extensive 2D NMR spectroscopic studies including H-1-H-1 COSY, long-range H-1-H-1 COSY,H-1-C-13 COSY, gHMQC, gHMBC and gHMQC-TOCSY experiments. The distinction between oxazole and isoxazole rings was made on the basis of the magnitude of heteronuclear one-bond (1)J(C2,H2) (or (1)J(C3,H3)) coupling constants. Complete analysis of the H-1 NMR spectra of 11-14 was achieved by iterative calculations. Gradient selected gHMQC-TOCSY spectra of phenanthro[9,10-d][1,3]oxazoles 11-14 were obtained at different mixing times (12,24,36,48 and 80 ms) to identify the spin system where the protons of phenanthrene ring at H-5, H-6 and at H-9 and H-7 and H-8 were highly overlapping.

New research progress on 1113-38-8 in 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 1113-38-8, Name is Ammonium oxalate, SMILES is O=C([O-])C([O-])=O.[NH4+].[NH4+], in an article , author is Li, Ting, once mentioned of 1113-38-8, Product Details of 1113-38-8.

Au(I)-catalyzed coupling of benzisoxazoles and ynamides was recently reported to synthesize challenging indoloquinoline core structures. In this report, we employed DFT methods to elucidate the mechanistic details of this reaction. The results reveal that the catalytic cycle involves initial coupling of ynamide with benzisoxazole, simultaneous ring opening of the isoxazole unit and attack of the dimethoxybenzene (DMOB) unit to gold carbenoid, proton transfer from the DMOB group to hydroxyl group, thioether migration, ring closure, and proton transfer. The experimentally observed ligand-controlled product selectivity is reproduced well by the calculations. The product selectivity-determining step is the ring opening of the isoxazole unit. The flexible P(t-Bu)(2)(o-biphenyl) ligand facilitates the approach of the DMOB group to gold carbenoid, which brings about significant C-H/pi interactions in the transition state for ring opening, and thus leads to the indoloquinoline product. The rigid 1,3-bis(diisopropylphenyl)imidazol-2-ylidene ligand prefers keeping the DMOB group away from the gold carbenoid, which can cause strong orbital interaction in the transition state for ring opening, and thus results in indole product.
