Benzisoxazole-3-acetic acid, a new synthetic growth regulator, was administered to protoplast cultures from Nicotiana tabacum and subsequently to the developed microcalluses, to test its activity on plant regeneration from protoplasts in different culture conditions. Such activity, compared to that of naphthalene-acetic acid, proved to be rather low in the stage of cellular division and microcallus formation but particulary high in the stage of shoot induction from microcallus, thus confirming that the activity of this compound is mainly morphogenetic.

Theoretical Insights into Ester-Directed Reactions between Propiolates with 1,2-Benzisoxazoles by Au(I) Catalyst: [4+2]-Annulation versus Michael-Type Products

Au(I)-catalyzed selective reactions of Et- and Bu-t-substituted propiolates (1a and 1a’) with 1,2-benzisoxazole(2a) provide a new strategy for purposefully access to desired bioactive heterocycles. Using DFT calculations, we have systematically investigated the detailed mechanisms and origins of the ester-controlled chemoselectivity. The calculated results indicated that both reactions are initiated by LAu+ pi-coordination, N nucleophilic attack, and NTf2–assisted stepwise H-shift, generating a nitrilium species identified as a common and requisite intermediate, which is significantly different from the experimentally proposed 6-alkoxy-1,3-oxazin-1-ium intermediate. Starting from the nitrilium intermediate, the newly established nucleophilic cyclization, alkene release, and NTf2–assisted stepwise protodeauration provides [4 + 2]-annulation product P-1, while the nitrilum dissociation, O nucleophilic attack, and NTf2–assisted stepwise protodeauration generates Michael-type product P-2. Further explorations showed that Bu-t-controlled chemoselectivity of P-1 over P-2 can be attributed to the energy favorable aromaticity of selective-determining nucleophilic cyclization TS. With substitution of Bu-t by Et group, the reversal of chemoselectivity to P-2 formation might be closely related to the presence of extremely unstable Et cation in ethylene release TS leading to P-1.

ANALYSIS OF SOLVENT EFFECTS ON THE DECARBOXYLATION OF BENZISOXAZOLE-3-CARBOXYLATE IONS USING LINEAR SOLVATION ENERGY RELATIONSHIPS – RELEVANCE TO CATALYSIS IN AN ANTIBODY-BINDING SITE

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.

Correlation between anticonvulsant activity and inhibitory action on glial gamma-aminobutyric acid uptake of the highly selective mouse gamma-aminobutyric acid transporter 1 inhibitor 3-hydroxy-4-amino-4,5,6,7-tetrahydro-1,2-benzisoxazole and its N-alkylated analogs

The inhibitory effect of 3-hydroxy-4-amino-4,5,6,7-tetrahydro1,2-benzisoxazole (exo-THPO) and its N-methylated (N-methylexo-THPO) and N-ethylated (N-ethyl-exo-THPO) analogs, derived from gamma-aminobutyric acid (GABA) and 4,5,6,7-tetrahydroisoxazolo[4,5-c]pyridin-3-ol (THPO) on GABA transport was investigated using cultured neocortical neurons (GABAergic) and astrocytes and cloned mouse GABA transporters GAT1-4 expressed in human embryonic kidney (HEK) 293 cells. Anticonvulsant activity was assessed after i.c.v. administration to Frings audiogenic seizure-susceptible mice. Anticonvulsant activity of the O-pivaloyloxymethyl prodrug of N-methyl-exo-THPO was assessed after i.p. administration. Results from these studies were compared with those obtained from similar studies with the novel anticonvulsant drug tiagabine, which acts via inhibition of GABA transport. exo-THPO and its N-alkyl analogs inhibited neuronal, astrocytic, and GAT1-mediated GABA transport but not GABA uptake mediated by GAT2-4. N-Methyl-exo-THPO was 8-fold more potent as an inhibitor of astrocytic versus neuronal GABA uptake. The IC50 value for inhibition of GABA uptake by GAT1 closely reflected its IC50 value for inhibition of neuronal uptake. Tiagabine was approximately 1000-fold more potent than exoTHPO and its alkyl derivatives as an inhibitor of GABA uptake in cultured neural cells and GAT1-expressing HEK 293 cells. exoTHPO, its alkylated analogs, and tiagabine displayed a time- and dose-dependent inhibition of audiogenic seizures after i.c.v. administration. N-Methyl-exo-THPO was the most potent anticonvulsant among the exo-THPO compounds tested and only slightly less potent than tiagabine. The findings suggest a correlation between anticonvulsant efficacy and selective inhibition of astroglial GABA uptake. Furthermore, results obtained with the N-methyl-exo-THPO prodrug demonstrate the feasibility of developing a glial-selective GABA uptake inhibitor with systemic bioavailability.

Accelerated decarboxylation of 6-nitrobenzisoxazole-3-carboxylate in imidazolium-based ionic liquids and surfactant ionic liquids

We report the use of the unimolecular, spontaneous decarboxylation of 6-nitrobenzisoxazole-3-carboxylate, 6-NBIC, as kinetic probe to investigate the properties of aqueous solutions of a series of ILs, 1-alkyl-3-methyl imidazolium derivatives. The ILs are denoted as [C(4)mim][X], where n indicates the number of carbon atoms in 1-alkyl chain. We studied [C(4)mim][Cl] with X = Cl-, Br-, and BF4-, and the surface-active ILs, SAILs, [C(12)mim][Cl], [C(12)mim][Br], and [C(16)mim][Br]. For comparison purposes we also studied nonmicellizing tetrallcylammonium chloride and bromide, denoted as TRAX, where R is alkyl group and X the anion. We observed a steep increase of values of k(obs) after a certain salt concentration for all the systems used. Electrical conductivity of various aqueous systems was measured, in an attempt to rationalize the kinetic effects. Data from conductivity and kinetic are consistent with the idea that after a certain, high, concentration aggregates of ILs form, and data from the kinetics suggest that water is someway squeezed out from these aggregates. As can be deduced from kinetics, properties of the aggregates formed by [C4mim][X] ILs correlate well with bulk water structure affecting properties of the salts, and seem to have no relation to surface effects.

Identification of the structural requirements of the receptor-binding affinity of diphenolic azoles to estrogen receptors alpha and beta by three-dimensional quantitative structure-activity relationship and structure-activity relationship analysis

Three-dimensional (31)) quantitative structure-activity relationship (QSAR) and structure-activity relationship (SAR) analyses were applied concurrently to a data set of highly selective estrogen receptor beta (ER beta) agonists. The data set consisted of diphenolic azoles characterized by similar structural skeletons but with different binding modes to the estrogen receptor site. Models were developed separately with respect to the relative binding affinities (RBAs) to ER alpha and ER beta. Steric and electrostatic fields were calculated for a training set of 72 compounds using comparative molecular field analysis (CoMFA). The model developed for ER alpha RBA yielded R-2 of 0.91 and q(cv)(2) of 0.60. The model developed for ER beta RBA yielded R-2 of 0.95 and q(cv)(2) of 0.40. Both models were validated successfully using an external test set of 32 compounds. A new concept of test set evaluation based on the variability of the biological response due to the variability of the living organism has been introduced. The CoMFA analysis was supported by a SAR study. In addition to the most favorable steric and electrostatic regions identified by CoMFA, a number of structural descriptors were identified as being important for binding. These are the number of substituents attached to the main skeleton of each compound, the largest distance between the oxygen atoms of each molecule, and the angle defined by the planes that split the phenyl or the naphthyl and the benzisoxazole or the benzoxazole moiety in a morphometrically longitudinal way.

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 35963-20-3 is helpful to your research. Category: Benzisoxazole.

STUDIES ON URICOSURIC DIURETICS .5. CONVENIENT AND EFFICIENT SYNTHESIS OF 2,3-DIHYDROBENZOFURAN DERIVATIVES

A practical procedure for synthesis of a new uricosuric agent, 5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid (1, AA-193) is described, which starts from 2,5-dichlorophenol (3b) and involves 5-chloro-6-hydroxy-3-phenyl-1,2-benzisoxazole (2) as the key intermediate. Successive treatment of 3b with benzoyl chloride-aluminum chloride (AlCl3) and hot ethanolic sodium hydroxide gives 4-benzoyl-2,5-dichlorophenol (8, 61%), which is oximated with hydroxylamine hydrochloride and then transformed into the benzisoxazole 2 (88%) with potassium hydroxide in N,N-dimethylformamide (DMF) (method C). The reaction of 2 with aqueous formaldehyde and dimethylamine affords the Mannich base Ila (97%), which is treated with a sulfonium ylide 12, 14 or 15 followed by heating with sodium hydroxide (NaOH) in ethanol (EtOH) to give 1 in high yield (method E).

EFFECTS OF ZONISAMIDE ON EXTRACELLULAR LEVELS OF MONOAMINE AND ITS METABOLITE, AND ON CA-2+ DEPENDENT DOPAMINE RELEASE

The effects of zonisamide (3-sulfamoylmethyl-1,2-benzisoxazole), a novel anticonvulsant, on extracellular levels of monoamine and its metabolite in the striatum and hippocampus, and Ca2+ dependent monoamine release in the striatum of freely moving rats were studied by microdialysis. Zonisamide increased dopamine, homovanillic acid and 5-hydroxyindoleacetic acid, and decreased 3,4-dihydroxyphenylacetic acid in the rat striatum. However, zonisamide showed no effect on Ca2+ dependent dopamine release in the rat striatum. In the hippocampus, zonisamide increased dopamine, homovanillic acid, serotonin and 5-hydroxyindoleacetic acid and decreased 3,4-dihydroxyphenylacetic acid. The present results suggest that zonisamide facilitates dopaminergic and serotoninergic neurotransmission but does not affect Ca2+ dependent dopamine release within therapeutic plasma concentrations.
