2-AROYLHEXANONES IN THE SYNTHESIS OF AZOLES

2-Aroylcyclohexanones, obtained from piperidinocyclohexene, react with hydrazine, hydroxylamine, and o-phenylenediamine to give the corresponding derivatives of bicyclic heterocycles – indazole, 2,1-benzisoxazole, and 2-spiro-cyclohexylbenzimidazole. The structure of a derivative of benzyloxazole has been determined by X-ray crystallography.

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 629-25-4 is helpful to your research. Quality Control of Sodium Laurate.

Synthesis and evaluation of 6-[C-11]methoxy-3-[2-[l-(phenylmethyl)-4-piperidinyl]ethyl]-1,2-benzisoxazole as an in vivo radioligand for acetylcholinesterase

6-Methoxy-3-[2-[1-(phenylmethyl)-4-piperidinyl]ethyl]-1,2-benzisoxazole is a high affinity (K-i = 8.2 nM) reversible inhibitor of acetylcholinesterase (AChE). The carbon-11 labeled form was prepared in high (>97%) radiochemical purity and with specific activities of 37 +/- 20 GBq/mu mol at end of synthesis, by the alkylation of the desmethyl precursor with [C-11]methyl trifluoromethanesulfonate in N,N dimethylformamide at room temperature. In vivo studies in mice demonstrated good blood brain permeability but essentially uniform regional brain distribution. Thus, despite in vitro and in vivo activity as an AChE inhibitor, 6-[C-11]methoxy-3-[2-[1-(phenylmethyl)-4-piperidinyl]ethyl]-1,2-benzisoxazole does not appear to be a good candidate for in vivo imaging studies of AChE in the mammalian brain.

Self-assembly in mixtures of sodium alkyl sulfates and alkyltrimethylammonium bromides: Aggregation behavior and catalytic properties

Two aqueous mixtures of cationic and anionic surfactants have been studied by means of conductometry, transmission electron microscopy, and microcalorimetry. Their catalytic effects on the decarboxylation of the kinetic probe 6-nitrobenzisoxazole-3-carboxylate (6-NBIC) were also examined in some detail. The mixtures differ profoundly in the hydrophobic match between both surfactant tails, which is perfect for dodecyltrimethylammonium bromide (DTAB) and sodium dodecyl sulfate (SDS) and poor for hexadecyltrimethylammonium bromide (CTAB) and sodium heptyl sulfate(SHS). This difference is reflected in the more pronounced synergism in critical aggregation concentration and catalytic efficiency of the DTAB/SDS mixture and in the phase behavior of the mixtures. CTAB and SHS can be mixed in a 1:1 ratio without precipitation, forming both small, unilamellar and large, multilamellar vesicles. In DTAB/SDS mixtures, however, precipitation of the catanionic surfactant occurs for a mole fraction of DTAB (x) between 0.3 and 0.7, while both vesicles and large bilayer fragments are formed for x = 0.8. The excess of DTAB in the x = 0.8 mixture results in the solubilization of the Vesicles by DTAB micelles close to the cmc of pure DTAB. A network of interconnected threadlike cylindrical micelles was found as an intermediate stage of aggregation between the vesicles and the mixed micelles. These cylindrical micelles are formed exclusively on further increasing the surfactant concentration.

Latent photochromism (pseudothermochromism) and photofatigue of crystalline 2-(2 ‘,4 ‘-dinitrobenzyl)pyridine

Along with the metastable 2-(2,4′-dinitrophenylmethylidene)-1,2-dihydropyridine (NH) and the unstable 6-aci-nitro-2-nitro-5-(2-pyridylmethylene)-1,3-cyclohexadiene (OH), the stable form of 2-(2′,4′-dinitrobenzyl)pyridine (DNBP), CH, is photochemically converted into small amounts of 1,2-bis(2′,4-dinitrophenyl)-1,2-bis(2′-pyridyl)ethane, trans-bis[5-nitro-2-(pyridine-2-carbonyl)phenyl]diazene N-oxide, 6-nitro-3-(2’-pyridyl)-2,1-benzisoxazole and 3-nitropyrido[1,2-b]quinolin-6-ium-11-olate. The latent photochromism of DNBP, as shown by x-ray analysis of the structures of the side-products and ESR/IR measurements, is attributed to open-shell reactions that are initiated by hydrogen photoabstraction and subsequent creation of two monoradicals, NH. and OH.. Large amounts of the radicals (ca 50% NH. and 70% OH) confined in the crystalline interior are persistent under ambient conditions. Through quasi-periodic reactions, the remaining radicals partially recover the ground-state isomers CH, NH and OH, or decay to the side-products, which results in crystalline photofatigue. Together with proton tunneling from the excited CH, the radical reactions represent dominant mechanism for the creation of NH and OH in the low-temperature regimes, but are successfully competed by the closed-shell reactions at higher temperatures. The precursor state, whose existence was assumed previously from transient absorption spectroscopy, may be identified as the radical OH.. The present work represents the first study of the photofatigue of a 2-(2,4-dinitrobenzyl)pyridine compound and extends the ‘classical’ mechanism of the photochromic reactions of nitrobenzylpyridines with a set of open-shell radical reaction routes.

Artificial enzymes based on imprinted liquid-crystalline materials

Liquid-crystal elastomers, imprinted around indole, are assessed as artificial enzymes for the isomerisation of benzisoxazole into 2-cyano phenol. Two types of material are synthesised, tested in the catalysis and compared with non-liquid-crystal imprinted polymers: an imprinted liquid-crystalline elastomer and a semi-interpenetrated imprinted liquid-crystal network. The catalytic effect of all materials is close. However, the main benefit for the liquid-crystal elastomer is shown to be the shape memory of the material at the molecular scale, because the isomerisation kinetics are found to be identical before and after deformation of the cavities either by thermal treatment up to the isotropic state or by solvent induced swelling. This fact is related to the coupling between the order and the conformation of the polymer chains, which is fixed by the crosslinking process. On the other hand, the imprinted sites of the semi-interpenetrated imprinted liquid-crystal elastomer are shown to be almost 100 times more active than the non-imprinted sites in the catalysis. This factor is only 22 for the corresponding non-liquid-crystalline network.

Background: Iloperidone is a second-generation antipsychotic drug approved in May 2009 by the US Food and Drug Administration (FDA) for the acute treatment of schizophrenia in adults. It is a piperidinyl-benzisoxazole derivative with mixed serotonin (5HT2A) and D2 dopamine antagonist properties. Objective: The purpose of this article was to review the pharmacology, pharmacokinetics, efficacy, safety, and role in treatment for iloperidone in schizophrenia. Methods: Scientific and clinical data were collected through searches of PubMed, ClinicalTrials.gov, International Pharmaceutical Abstracts, and the FDA, using the search term iloperidone, and limited to English-language articles. Reference lists were reviewed for additional publications. Dates included the beginning of the database through 2010. No limits were placed on study design. Results: In a 4-week Phase III trial, iloperidone 12 mg twice daily lowered the Positive and Negative Syndrome Scale (PANSS) total scores to a significantly greater extent than did placebo (-12 vs -7.1; P < 0.01). The ziprasidone active control also separated from placebo (-12.3 vs -7.1; P < 0.05). A pooled analysis of 3 Phase III trials compared iloperidone in divided doses to placebo. The primary outcome was reduction in PANSS scores. Study 1 included iloperidone 4, 8, or 12 mg/d, haloperidol as an active control, and placebo. The PANSS reduction in the 12 mg/d group was significantly greater at end point versus baseline when compared with placebo (-9.9 vs -4.6; P = 0.047). Study 2 included iloperidone 4 to 8 mg/d or 10 to 16 mg/d, risperidone 4 to 8 mg/d, or placebo. The primary efficacy measure was change from baseline to end point in the Brief Psychiatric Rating Scale (BPRS). Improvement from baseline on all iloperidone doses was significantly greater than with placebo (4-8 mg/d group: -6.2, P = 0.012; 10-16 mg/d group: -7.2, P = 0.001; placebo, -2.5). Study 3 included iloperidone 12 to 16 mg/d, risperidone 6 to 8 mg/d, and placebo. The results on the primary efficacy variable, reduction in the BPRS score, was not significant for the 12 to 16 mg/d group versus placebo (-7.1 vs -5.0; P = 0.09), but was significant for the 20 to 24 mg/d iloperidone group (-8.6 vs -5.0; P = 0.01) and for the risperidone group (-11.5 vs 5.0; P < 0.001). A 52-week maintenance trial included iloperidone versus haloperidol as an active control. The primary efficacy variable was time to relapse. Comparison of mean time to relapse of the 2 arms showed no significant difference. The most common adverse events (AEs) associated with iloperidone were dizziness (5.1%-23.2%), dry mouth (5.2%-10.4%), somnolence (4%-13%), and dyspepsia (4.8%-7.8%). AEs appeared dose related. Prescribing information recommends a starting dosage of 1 mg twice daily and then titrated over 7 days to reach a target dosage of 12 to 24 mg/d. The titration is necessary to reduce the risk of orthostatic hypotension-related dizziness. Conclusions: Data support that when titrated slowly to a therapeutic dosage, iloperidone is generally well tolerated, has a favorable safety profile, and is an effective treatment option in patients with schizophrenia. Its place in therapy and performance in a typical patient population remain to be established. Slow initial titration and twice-daily dosing are potential disadvantages.

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.
