CHARACTERIZATION OF HUMAN LIVER MICROSOMAL CYTOCHROME-P450 INVOLVED IN THE REDUCTIVE METABOLISM OF ZONISAMIDE

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide) was metabolized to 2-sulfamoylacetylphenol (SMAP) in human liver microsomes under anaerobic conditions. The formation of SMAP was remarkably inhibited by cimetidine, n-octylamine, ketoconazole, and carbon monoxide, indicating that a cytochrome P450 is involved in the metabolism of zonisamide to SMAP in human liver microsomes. The SMAP-producing activity did not correlate with the spectrally determined amount of cytochrome P450. In contrast, the SMAP-producing activity from zonisamide correlated closely with the activity of testosterone 6beta-hydroxylase (r2 = 0.96) and correlated slightly but significantly with the activity of imipramine 2-hydroxylase (r2 = 0.28), but not with those of aniline hydroxylase (r2= 0.09) or benzphetamine N-demethylase (r2= 0.20). In addition, immunoquantitation of cytochrome P450 enzymes in 21 human liver microsomal samples revealed that SMAP formation correlated closely with the amount of P450 3A enzyme and correlated moderately well with that of P450 2D6 but not with that of P450 2C enzyme in human liver microsomes. P450 3A4 exhibited SMAP-producing activity in a reconstituted monooxygenase system. The metabolism of zonisamide to SMAP was almost completely inhibited by anti-P450 3A4 antibody but not by anti-P450 2C9 or anti-P450 2D6 antibodies, suggesting that the amount of P450 3A enzyme may be a major factor influencing the level of metabolism of zonisamide to SMAP in human liver microsomes.

AUXIN STRUCTURE AND ACTIVITY ON TOMATO MORPHOGENESIS INVITRO AND PEA STEM ELONGATION

In order to understand better the relationship between auxin structure and activity on morphogenesis and cell elongation, six different auxins were tested on the regeneration of tomato (Lycopersicon esculentum Miller var. Alice) from cotyledons and on pea (Pisum sativum L. var. Alaska) stem elongation. The auxins were: indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), 1, 2-benzisoxazole-3-acetic acid (BOA), 1,2-benzisothiazole-3-acetic acid (BIA), 1-naphthalenacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D). All these compounds obey the minimum requirement rules for auxin activity and all were effective on cell elongation. At the dose of 10-mu-M and in the absence of cytokinin, they all, except 2,4-D, induced roots, while in the presence of cytokinin they induced shoots, roots, hairy root-like filaments (HRLF) or callus depending on their concentration. The morphogenetic pattern did not change by varying cytokinin concentration. We conclude that auxin structure plays a minor role in morphogenesis or cell elongation, because it is only responsible for variations in the level of auxin activity.

Synthesis of 2,1-Benzisoxazoles by Nucleophilic Substitution of Hydrogen in Nitroarenes Activated by the Azole Ring

Reaction of 1-nitro-4-(1,2,3-triazolyl/tetrazolyl)benzenes with arylacetonitriles in an alcoholic medium in the presence of excess alkali gives novel 2,1-benzisoxazoles. These findings indicate a high reactivity of nitroarenes activated by the azole ring due to their electron-deficient character. Moreover, it was found that annulation of the isoxazole ring occurred regioselectively in disubstituted nitroarenes. In the case of 1-(4-nitrophenyl)-1H-tetrazole, the tetrazole ring cleaved faster than the sigma(H)-adduct was formed.

Mechanism and Origins of Product Selectivity of Au-Catalyzed Coupling Benzisoxazoles with Ynamides: A Computational Study

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.

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. Computed Properties of C2H10N2O5.

A novel selective gamma-aminobutyric acid transport inhibitor demonstrates a functional role for GABA transporter subtype GAT2/BGT-1 in the CNS

The system of GABA transporters in neural cells constitutes an efficient mechanism for terminating inhibitory GABAergic neurotransmission. This transport system is an important therapeutical target in epileptic disorders, but potentially also in other neurological disorders. Thus, selective intervention in GABA uptake has been the subject of extensive research for several decades. In a series of lipophilic diaromatic derivatives of (RS)3-hydroxy-4-amino-4,5,6,7-tetrahydro-1,2-benzisoxazole (exo-THPO), N-[4,4-bis(3-methyl-2-thienyl)-3-butenyl]-3-hydroxy-4-(methylamino)4,5,6,7-tetrahydrobenzo[d]isoxazol-3-ol (EF1502) turned out to be an equipotent inhibitor at the mouse transporters GAT1 and GAT2 (BGT-1) but inactive at GAT3 and GAT4. This novel pharmacological profile among GABA uptake inhibitors prompted a thorough investigation of the in vivo properties of this compound. These investigations have for the first time demonstrated a functional role for GABA transporter subtype GAT2/ BGT-1, which points to the therapeutic relevance of inhibiting this transporter subtype. An overview of the development and characterisation of EF1502 is presented here. (C) 2006 Elsevier Ltd. All rights reserved.

Competitive Copper Catalysis in the Condensation of Primary Nitro Compounds with Terminal Alkynes: Synthesis of Isoxazoles

Isoxazoles, mainly 3,5-disubstituted, are prepared by catalytic condensation of primary nitro compounds with terminal acetylenes by using a copper/base catalytic system. The additional catalytic effect of the copper(II) salts is evidenced by comparing the kinetic profiles. Selectivity dependence on reaction conditions is considered for phenylacetylene in the following competitive processes: oxidative coupling of terminal alkynes to conjugated diynes catalyzed by Cu-II and base in the presence of air; production of furazans beside condensation with benzoylnitromethane to 3-benzoylisoxazoles, as a result of the reaction of the dipolarophile with 3,4-dibenzoylfuroxan; addition of electron-poor alkynes (e.g., methyl propiolate) with themselves and with the nitro compound. Thus, oxidative coupling is negligible in reactions with active nitro compounds, whereas with nitroalkanes both products are observed: only trace amounts of isoxazoles are detected without copper. Similarly, in the presence of copper, 3-benzoyl-5-phenylisoxazole is predominant over the furazan. Furthermore, condensations of electron-poor alkynes give complex reaction mixtures in the presence of base alone, but cycloadducts are conveniently prepared with copper. The results indicate the practical and general utility of this catalytic method for synthetic practice.

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 2836-32-0, in my other articles.

HDAC and NF-kappa B mediated cytotoxicity induced by novel N-Chloro beta-lactams and benzisoxazole derivatives

Novel N-chloro a-Lactam and benzisoxazole derivatives were successfully synthesized with excellent yields (92-96%) under simple and mild reaction conditions. The beta-lactams as a class acquired importance since the discovery of penicillin which contains beta-lactam unit as an essential structural feature of its molecule, this interest continued unabated because of the therapeutic importance of beta-lactam antibiotics. In silico studies of the compounds with cancer drug target enzymes showed the inhibition of HDAC (Histone Deacetylase) and NF-kappa B (nuclear factor kappa-light-chain-enhancer of activated B cells) significantly. The compounds were then investigated for the inhibitory potential against the same enzymes in vitro. NF-kappa B inhibition was investigated by trans activation assay using HEK293/NF-kappa B-luc cells. Overall, the synthesized compounds induce the cancer cell toxicity by restraining the NF-kappa B transcription factor mediated by HDAC inhibition and thus the compounds act as dual inhibitors.

Aromaticity of anthranil and its isomers, 1,2-benzisoxazole and benzoxazole

Direct computation of the pi-current density, that is, the ‘ring current’, of anthranil (1) and its isomers 1,2-benzisoxazole (2) and benzoxazole (3) reveals different patterns of current flow: isomers 2 and 3 sustain strong benzene-like currents in the six-membered and bifurcated flow in the five-membered ring, whereas, in keeping with its lower thermodynamic stability, 1 has only a perimeter circulation without separate monocycle currents. Although the ring current criterion does not offer a sharp distinction between 2 and 3, their difference in thermodynamic stability is identical to that between isoxazole (4) and oxazole (5) suggesting an aromaticity order 1 < 2 approximate to 3.

RISPERIDONE

Risperidone, a benzisoxazole derivative, is a novel antipsychotic agent that has an extremely strong binding affinity for serotonin 5-HT2 receptors, a strong binding affinity for dopamine D2 receptors, and a high affinity for alpha1- and alpha2-adrenergic receptors and histamine H-1 receptors. Its affinity for serotonin receptors is approximately 200 times greater than that of haloperidol, and its dopamine antagonistic potency is comparable to that of haloperidol. Its major metabolite, 9-hydroxyrisperidone, has similar pharmacologic activity, and thus the parent compound and metabolite form the active antipsychotic moiety Clinical trials demonstrate that risperidone is an effective antipsychotic agent that improves negative as well as positive symptoms of schizophrenia. At recommended dosages, the frequency of extrapyramidal side effects is no greater than that seen with placebo. The drug appears to be an advance in the treatment of psychoses.
