Iloperidone, 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl]-1-piperidinyl]propoxy]-3-methoxyphenyl]ethanone, is currently undergoing clinical trials as a potential antipsychotic agent. Iloperidone was found to be extensively metabolized to a number of metabolites by rats, dogs, and humans, LC/MS/MS was used to characterize and identify metabolites of iloperidone present in complex biological mixtures obtained from all three species. Identification of some of the unknown metabolites in rat bile was achieved successfully by combination of LC/NMR and LC/MS with a minimum amount of sample cleanup. The utility of coupling a semipreparative HPLC to LC/MS instrument for further characterization of collected metabolites was demonstrated. It was shown that iloperidone was metabolized by O-dealkylation processes to yield 6-fluoro-3-[1-[3-hydroxypropyl)-4-piperidinyl]-1,2-benzisoxazole and 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]-2-hydroxyphenyl]ethanone. Oxidative N-dealkylation led to the formation of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole and a secondary metabolite, 3-[(4-acetyl-2-methoxy)phenoxy]propionic acid. Iloperidone was reduced to produce 4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]-3-methoxy-alpha-methylbenzenemethanol as the major metabolite in humans and rats. Hydroxylation of iloperidone produced 1-[4-[3-[4-(6-fluoro-1 ,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]-2-hydroxy-5-methoxyphenyl]ethanone and 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1 -piperidinyl]-3-methoxyphenyl]propoxy]-2-hydroxyethanone, the later of which was found to be the principal metabolite in dogs. The identities of all these metabolites were established by comparing the LC/MS retention times and mass spectral data with synthetic standards.

The Kemp elimination reaction is the most widely used in the de novo design of new enzymes. The effect of two different kinds of electric fields in the reactions of acetate as a base with benzisoxazole and 5-nitrobenzisoxazole as substrates have been theoretically studied. The effect of the solvent reaction field has been calculated using the SMD continuum model for several solvents; we have shown that solvents inhibit both reactions, the decrease of the reaction rate being larger as far as the dielectric constant is increased. The diminution of the reaction rate is especially remarkable between aprotic organic solvents and protic solvents as water, the electrostatic term of the hydrogen bonds being the main factor for the large inhibitory effect of water. The presence of an external electric field oriented in the direction of the charge transfer (z axis) increases it and, so, the reaction rate. In the reaction of the nitro compound, if the electric field is oriented in an orthogonal direction (x axis) the charge transfer to the NO2 group is favored and there is a subsequent increase of the reaction rate. However, this increase is smaller than the one produced by the field in the z axis. It is worthwhile mentioning that one of the main effects of external electric fields of intermediate intensity is the reorientation of the reactants. Finally, the implications of our results in the de novo design of enzymes are discussed.

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 6009-70-7 is helpful to your research. COA of Formula: https://www.ambeed.com/products/6009-70-7.html.

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. 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 619-05-6.

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.

Neuroleptic malignant syndrome is thought to be a result of dopamine D-2 receptor blockade in the striatum of the basal ganglia. Risperidone, a benzisoxazole derivative antipsychotic, has high serotonin 5-HT2 receptor blockade and dose-related D-2 receptor blockade. The high ratio is believed to impart the low frequency of extrapyramidal symptoms with risperidone at low dosages. With this low frequency of extrapyramidal symptoms, it was thought the frequency of neuroleptic malignant syndrome might also be lowered. A 73-year-old woman developed neuroleptic malignant syndrome after monotherapy with risperidone. The syndrome reversed after discontinuing risperidone and starting treatment with dantrolene and bromocriptine. It appears that the protection from extrapyramidal side effects observed with risperidone does not ensure protection from neuroleptic malignant syndrome.

1,2-Benz-isoxazol-3-acetic acid is slightly toxic to unorganized growing carrot cells and completely prevents somatic embryogenesis beyond the globular stage. Its action is time dependent: if added early, it affects the determination of the early stages; if added later, after determination has occurred, it has practically no effect. The blocked forms can evolve, in the presence of the compound, creating secondary embryos that, in turn, are arrested at the globular stage. Since the secondary embryos adhere to the primary ones, irregular polyembryonic masses of typical appearance are created. The internal structures of the blocked globular embryos were examined and were shown to be enlarged, vacuolized and detached from the central cells. The protoderm also displayed an altered appearance. These data, when considered together with the effects of the compound on rooting and callus formation, suggest that benz-isoxazol acetic acid acts as a weak auxin.

A new class of phosphoramidate derivatives of 6-fluoro-3-(piperidin-4-yl)benzo[d]isoxazole were synthesized in good to excellent yields (78-96%) by an in situ, three-step process. All the synthesized molecules were evaluated for anti-bacterial and anti-fungal activities using in vitro and in silico methods. The results revealed that the compounds 4b, 4d, 4h, 4i, and 4j exhibited the most promising anti-bacterial activity against S. aureus, B. subtilis, K. pneumoniae, S. typhi and P. mirabilis and anti-fungal activity against A. niger and A. flavus when compared with the standard drugs Norfloxacin and Nystatin at concentrations of 25, 50, 75 and 100 mu g/mL. The rest of the title compounds have shown moderate activity against all the bacterial and fungal strains. Molecular docking studies revealed that the synthesized compounds have exhibited significant binding modes with high dock scores ranging from -7.2 to -9.5 against 3V2B protein when compared with the standard drugs Norfloxacin (-5.8) and Nystatin (-6.6) respectively. Hence, it is suggested that the synthesized phosphoramidate derivatives of 6-fluoro-3-(piperidin-4-yl)benzo[d]isoxazole will stand as the promising antimicrobial drug candidates in future.

A facile preparation of 3-acyl-substituted isoxazolines, benzisoxazoles, and isoxazoles from the corresponding 3-carboxylate esters is described. The process, involving reaction of the ester derivative of 3-carboxylic acid substituted heterocycles with Grignard or alkynyl lithium reagents, leads to direct generation of the corresponding 3-acyl heterocycle. The presence of alpha-imino ester moieties in the heterocyclic substrates for the reactions is thought to be a key feature governing the nature of these transformations. The synthetic utility of the new methodology is demonstrated by its application in a two-step route for the preparation of novel linked bis-heterocycles. (C) 2012 Elsevier Ltd. All rights reserved.
