Synthesis and Study of Oxadisilole-Fused Benzisoxazoles or Naphthisoxazoles

Oxadisilole-fused benzisoxazoles or naphthisoxazoles were obtained through 1,3-dipolar cycloaddition of arynes with nitrile oxides in good yields at room temperature. Key to the procedure is the simultaneous in situ generation of reactive nitrile oxides from arenecarbohydroximoyl chlorides and aryne reactants from benzobis(oxadisilole) or 2,3-naphthoxadisilole. One oxadisilole-fused benzisoxazole is a new precursor of a benzyne formed by a phenyliodination/fluoride-induced elimination protocol. By using this benzyne, cycloadducts were synthesized in good yields. The de-oxadisilole reaction of some of the oxadisilole-fused benzisoxazoles could be easily conducted with a 1.0 M solution of tetrabutylammonium fluoride in THF at room temperature.

Studies on the synthetic compatibility of aryloxime linkers in the solid-phase synthesis of 3-aminobenzisoxazoles

Further exploration of the scope of our solid-phase method for the synthesis of 3 -aminobenzisoxazoles (using the Kaiser oxime resin 1) is described. The effects of base, leaving group, and solvent on the nucleophilic aromatic substitution based resin-loading reaction are discussed. Representative aryloxime intermediates were subjected to a variety of acidic conditions commonly used in protecting group removal to establish the acid stability profile of this linker. Regioselectivity was evaluated with various di- and trifluorobenzonitriles, which gave single benzisoxazole products after loading and cyclorelease reactions. Substituent effects observed in the course of the acid stability and regioselectivity studies suggest that the nitrile plays a critical role in the oxime hydrolysis mechanism. Finally, to establish the compatibility of the aryloxime linker with a variety of useful on-resin synthetic transformations, functionalized substrates were loaded onto resin 1, and carbon-nitrogen, carbon-oxygen, and carbon-carbon bond-forming reactions were successfully executed.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 619-05-6, you can contact me at any time and look forward to more communication. Application In Synthesis of 3,4-Diaminobenzoic acid.

An assessment of iloperidone for the treatment of schizophrenia

Iloperidone (Novartis’ Zomaril(TM)) is an atypical antipsychotic agent for the treatment of schizophrenia. Current trends in the treatment of schizophrenia indicate that some atypical antipsychotics are being recommended as first-line therapy. Atypical antipsychotics, in addition to being dopamine (D) receptor antagonists, are all relatively potent serotonin (5-HT) receptor antagonists and are less likely than conventional dopamine antagonists to induce movement disorders. However, all of these agents differ in their receptor profiles and clinical profiles. Iloperidone, a benzisoxazole, is a mixed 5-HT2A/D-2 antagonist. Iloperidone was found to be more potent than its analogues when compared with haloperidol in antagonising climbing behaviour in mice. Iloperidone is extensively metabolised and the main circulating metabolite is reduced iloperidone. In patients treated with iloperidone, a low incidence of extrapyramidal symptoms and weight gain has been shown. Data from Phase II trials demonstrated efficacy in patients at doses of 8 mg/day and tolerability was good up to 32 mg/day. Phase III prospective, double-blind, randomised trials with iloperidone are in progress under the ZEUS (Zomari(TM)Efficacy Utility and Safety) programme involving 3300 patients. Iloperidone, with a balance of activity at the dopaminergic and serotonergic receptors, has obvious advantages over clozapine and olanzapine, both of which have a similar receptor profile as they favour serotonergic over dopamine receptors. Iloperidone is likely to reach the market in 2001 and has favourable prospects in the atypical antipsychotic market for schizophrenia, which is expanding from US$ 1.5 billion in 2000 to US$ 3 billion in 2005.

Cyclisation and decarboxylation in zwitterionic micelles: Effects of head group structure

The spontaneous decarboxylation of 6-nitrobenzisoxazole-3-carboxylate ion is strongly catalysed by micelles of zwitterionic surfactants, viz., sulfobetaines [C(14)H(29)N(+)R(2)(CH2)(3)SO3-, R = Me, Pr and C16H33 N(+)Me(2)(CH2)(3)SO3-] and amine oxides (C(14)H(29)N(+)R(2)O(-), R = Me, Pr), with rates enhanced by factors of up to 1800. These micelles and those of the corresponding carboxybetaines are more effective catalysts than those of the corresponding cationic surfactants, In all cases a change from Me to Pr at the head group speeds reaction by factors of ca. 5-8 for the sulfobetaines and amine oxides and ca. 14 for the cationic surfactants. Cyclizations of the o-3-halopropyloxyphenoxide ions (halogen = Br, I), which are intramolecular S(N)2 reactions, are modestly micellar catalysed, but structural effects on the micellar catalysis by cationic and betaine surfactants are in the same sequence, as for decarboxylation.

Effect of anti-inflammatory bowel disease drug, E3040, on urate transport in rat renal brush border membrane vesicles

To confirm the assumption that 6-hydroxy-5,7-dimethyl-2-methylamino-4-(3-pyridylmethyl)benzothiazole (E3040) acts on urate reabsorption by inhibiting urate-anion exchange at the luminal membrane of renal tubules, we investigated the inhibitory effect of E3040 and its two conjugated metabolites on hydroxyl ion (OH-) gradient-dependent urate uptake into brush border membrane vesicles from rat renal cortex and compared it with other uricosuric agents. The order of potency was AA193 (5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid)> benzbromarone > E3040 > probenecid > E3040 sulfate > E3040 glucuronide. Furthermore, kinetic analysis revealed that E3040 may be a competitive inhibitor of the OH- gradient-dependent uptake of urate into brush border membrane vesicles. (C) 2000 Elsevier Science B.V.

PLANT-REGENERATION FROM EXPLANT AND PROTOPLAST-DERIVED CALLUSES OF MEDICAGO-LITTORALIS

Plant regeneration from explant and protoplast derived callus has been achieved in Medicago littoralis cv. Harbinger 1886, an annual legume resistant to the fungus Pseudopeziza medicaginis. Callus was induced from different tissue explants and the fastest growth rate was observed for hypocotyls in B5 medium with 2 mg l(-1) 2,4-dichlorophenoxyacetic acid and 0.5 mg l(-1) N-6-benzyladenine. Protoplasts were isolated from cotyledons and leaves of sterile plants and from callus; the first two kinds of protoplasts showed a plating efficiency of 5.6% and 5%, respectively, when embedded in agarose. Plant regeneration occurred on media containing N-6-Delta(2)isopentenyl-adenine combined with indole-3-acetic acid or 1,2-benzisoxazole-3-acetic acid, and on media with N-6-benzyladenine plus alpha-naphtaleneacetic acid; a cytokinin/auxin ratio higher than 1 induced embryos while a ratio around 1 stimulated shoot formation. Embryo development and rooting of shoots were performed in RL medium without growth regulators.

EXTRACTIVE SPECTROPHOTOMETRIC DETERMINATION OF QUETIAPINE FUMARATE IN PHARMACEUTICALS AND HUMAN URINE USING CALMAGITE AS AN ION-PAIR REAGENT

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.
