Kemp elimination: A probe reaction to study ionic liquids properties

The amino induced elimination of benzisoxazole into the relevant o-cyanophenolate ion (Kemp elimination) has been studied in [bmim][BF4] solution at 298 K. To have information about the interactions between reactants and ionic liquid, the reaction has been carried out at different temperatures (293-313 K). Several primary, secondary, and tertiary amines have been used to study the effect of amine structure on the reaction rate. The collected data show that the amine structure seems to have a crucial role in determining the reaction rate. Furthermore, as different cation or anion structures of an ionic liquid can significantly affect its properties, the title reaction has been performed in four different ionic liquids ([bmim][PF6], [bmim][NTf2], [bm(2)im][NTf2], and [bmpyrr][NTf2]), using pyrrolidine and piperidine as model amines. An H-donor negative solvent (MeOH and [bmim][NTf2]) effect on reaction rate was detected. Finally, a narrow range of activation parameters was calculated both for the reaction induced by different amines and for pyrrolidine and piperidine, in the presence of different ILs. This fact suggests the occurrence of an early transition state.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 701-97-3. The above is the message from the blog manager. Computed Properties of C9H16O2.

Zonisamide: Review of Recent Clinical Evidence for Treatment of Epilepsy

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.

SYNTHESIS OF HYDROPHOBICALLY AND ELECTROSTATICALLY MODIFIED POLYACRYLAMIDES AND THEIR CATALYTIC EFFECTS ON THE UNIMOLECULAR DECARBOXYLATION OF 6-NITROBENZISOXAZOLE-3-CARBOXYLATE ANION

A series of hydrophobically and electrostatically modified polyacrylamides (Copol(AM-C12)) has been synthesized by radical-initiated copolymerization of acrylamide with n-dodecylmethyldiallylammonium bromide as the hydrophobe in aqueous solution using ammonium persulfate as the initiator. The formation of hydrophobic microdomains of the copolymers was revealed by large hypsochromic shifts of the long-wavelength absorption band of the solvatochromic probe Methyl Orange, noncovalently bound to the macromolecule. It was found that the microdomains formed by these copolymers in aqueous solution are more hydrophobic than those of the cationic polysoaps poly(alkylmethyldiallylammonium halides) containing the same n-dodecyl groups as the side chains as a result of the reduced electrostatic repulsions at the periphery of the microdomains. The reduced cationic character of the copolymers Copol(AM-C12) most likely also accounts for the observation that the anionic dye Methyl Orange does not; induce microdomain formation in aqueous solution. The effect of the hydrophobically and electrostatically modified polyacrylamides on the unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate anion (6-NBIC) has been investigated in aqueous solutions at pH 11.3 and 30 degrees C. It is suggested that the relatively modest catalytic effects induced by Copol(AM-C12) should be ascribed to hydrogen-bond stabilization of the initial state by NH groups in the macromolecules. The decarboxylation rates of 6-NBIC at binding sites in hydrophobic microdomains increase with increasing n-dodecyl group content in the copolymers.

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 98-89-5 is helpful to your research. Name: Cyclohexanecarboxylic acid.

Guest Binding and Catalysis in the Cavity of a Cubic Coordination Cage

An M8L12 coordination cage, which is water-soluble but has a hydrophobic interior cavity, is an effective host for a wide range of small organic guests; the factors responsible for guest binding have been investigated in detail. Benzisoxazole is a competent guest and, when bound, undergoes the Kemp elimination reaction with a rate acceleration of up to 2 x 10(5) times compared to the reaction of unbound benzisoxazole; the reasons for this have been analyzed.

Electric Literature of 532-32-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 532-32-1 is helpful to your research.

SYNTHESIS AND CATALYTIC PROPERTIES OF NON-CROSS-LINKED AND CROSS-LINKED POLY(ALKYLMETHYLDIALLYLAMMONIUM BROMIDES) HAVING DECYL, OCTYL, AND HEXYL SIDE-CHAINS

A family of non-cross-linked and cross-linked copolymers containing decyl, octyl, and hexyl groups as side chains ((CL)-CopolC1-10, (CL)-CopolC1-8, and (CL)-CopolC1-6, respectively) were synthesized by radical-initiated cyclocopolymerization of alkylmethyldiallylammonium bromide monomers without and with a small amount of N,N’-methylenebisacrylamide as a cross-linking agent in aqueous solution. Their H-1 NMR and IR spectra indicated the presence of five-membered rings cross-linked without and with N,N’-methylenebisacrylamide in the macromolecules. Viscosity measurements showed that the cross-linked copolymers exhibit a larger reduced viscosity in aqueous solution with increasing cross-linking agent content in the copolymers. For(CL)-CopolC1-10, the conformational transition to compact coils was indicated by changes of the reduced viscosity in dilute aqueous solutions. At higher concentrations, intermolecular aggregation was also revealed and increased with increasing the percentage of cross-linking for CL-CopolC1-10. (CL)-CopolC1-8 and (CL)-CopolC1-6 showed extented molecular dimensions in aqueous solution. The hydrophobic microdomains of the non-cross-linked and cross-linked copolymers were probed by hypsochromic shifts of the long-wavelength absorption band of Methyl Orange as a solvatochromic agent, noncovalently bound to the macromolecule. The unimolecular decarboxylation of 6-nitrobenzisox-azole-3-carboxylate (6-NBIC), catalyzed by these copolymers in aqueous solution, was used as a model reaction to study the influence of polysoap microenviroment on reactivity. Depending on the hydrophobic group content, (CL)-CopolC1-10 led to a remarkably large rate enhancement, whereas (CL)-CopolC1-8 induced only modest rate acceleration for the decarboxylation of 6-NBIC. A small rate enhancement was observed in the presence of(CL)-CopolC1-6. The decarboxylation rate is also sensitive to changes of the percentage of cross-linking in the macromolecules. A maximum in rate constant was found at about 0.2% (w/w) cross-linking agent for CL-CopolC1-10 and at about 0.4% (w/w) for CL-CopolC1-8 in plots of the rate constant vs cross-linking agent content.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 68-04-2. HPLC of Formula: C6H5Na3O7.

Research and development of zonisamide, a new type of antiepileptic drug

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide, AD-810) is a broad spectrum antiepileptic drug which has been launched in Japan and South Korea. It lacks the ureide structure included in most of the existing antiepileptic drugs. Zonisamide was synthesized by the sulfonation and the successive amination of 1,2-benzisoxazole-3-acetic acid in a very poor yield. After several efforts to optimaize the compound, zonisamide was selected based on the balance of the efficacy and safety. The yield was greatly improved by the development of new synthetic routes. Zonisamide suppressed maximal electroshock seizures in mice, rats, rabbits and dogs. Its therapeutic plasma concentration range between anticonvulsant and neurotoxic effects was much wider than that of the existing antiepileptic drugs. In electroencephalographic studies on animal models of epilepsy, zonisamide, like phenytoin and carbamazepine, restricted the spread or propagation of seizures and, like sodium valproate, it suppressed the epileptogenic focus activity. Zonisamide was effective in several kindling models. In clinical studies, zonisamide exerted the efficacy against partial seizures (simple, complex, secondarily generalized seizures and some generalized seizures (tonic-clonic, tonic, atypical absence seizures) that were comparable to that of carbamazepine and sodium valproate, respectively. Zonisamide was also effective in monotherapy. The adverse effects related with zonisamide were mainly drowsiness, ataxia, loss of appetite and gastrointestinal symptoms. Serious adverse effects which may be life-threatening have not been reported.
