Synthesis and spectroscopic characterization of two new thiosaccharinate salts. Molecular structure of bis(triphenylphosphine)iminium thiosaccharinate, PNP(tsac)

We report the synthesis, FTIR, Raman and NMR spectroscopic features of bis(triphenylphosphine)iminium and tetrabutylammonium thiosaccharinates, PNP(tsac) and NBu 4 (tsac) (tsac: thiosaccharinate anion, PNP: bis(triphenylphosphine)iminium). The molecular structure of the former compound was determined by X-ray diffraction methods. The salt crystallizes in the monoclinic P21/n space group with a = 9.6481(9), b = 29.258(3), c = 13.177(2)?A, beta = 97.53(1), and Z = 4 molecules per unit cell. Slight but significant changes in the bonding structure of the thiosaccharinate anion as compared with those reported for the neutral molecule are observed. Springer-Verlag 2007.

Gas-phase cyclisation reactions of 1-(2-arylthiophenyl)alkaniminyl and 2-(aryliminomethyl)thiophenoxyl radicals

Flash vacuum pyrolysis (FVP) of the oxime ethers 12-14 and of the sulfides 18-20 at 650C (10-2-10-3 Torr) gave products derived from the corresponding iminyl and thiophenoxyl radicals. In all cases, benz[d]isothiazoles (e.g., 26) are formed as major products via SHi mechanisms though the yields are greatest with the iminyl precursors. Alternative pathways observed from the thiophenoxyls in specific cases include the formation of the anilinobenzothiophene 36 and of dibenzothiophene 23, via an SHi process and a spirodienyl rearrangement, respectively. There is no evidence for signicant interconversion of the iminyl and thiophenoxyl species.

Antipsychotics for treatment of delirium in hospitalised non-ICU patients

Background: Guidelines suggest limited and cautious use of antipsychotics for treatment of delirium where nonpharmacological interventions have failed and symptoms remain distressing or dangerous, or both. It is unclear how well these recommendations are supported by current evidence. Objectives: Our primary objective was to assess the efficacy of antipsychotics versus nonantipsychotics or placebo on the duration of delirium in hospitalised adults. Our secondary objectives were to compare the efficacy of: 1) antipsychotics versus nonantipsychotics or placebo on delirium severity and resolution, mortality, hospital length of stay, discharge disposition, health-related quality of life, and adverse effects; and 2) atypical vs. typical antipsychotics for reducing delirium duration, severity, and resolution, hospital mortality and length of stay, discharge disposition, health-related quality of life, and adverse effects. Search methods: We searched MEDLINE, Embase, Cochrane EBM Reviews, CINAHL, Thomson Reuters Web of Science and the Latin American and Caribbean Health Sciences Literature (LILACS) from their respective inception dates until July 2017. We also searched the Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment Database, Web of Science ISI Proceedings, and other grey literature. Selection criteria: We included randomised and quasi-randomised trials comparing 1) antipsychotics to nonantipsychotics or placebo and 2) typical to atypical antipsychotics for the treatment of delirium in adult hospitalised (but not critically ill) patients. Data collection and analysis: We examined titles and abstracts of identified studies to determine eligibility. We extracted data independently in duplicate. Disagreements were settled by further discussion and consensus. We used risk ratios (RR) with 95% confidence intervals (CI) as a measure of treatment effect for dichotomous outcomes, and between-group standardised mean differences (SMD) with 95% CI for continuous outcomes. Main results: We included nine trials that recruited 727 participants. Four of the nine trials included a comparison of an antipsychotic to a nonantipsychotic drug or placebo and seven included a comparison of a typical to an atypical antipsychotic. The study populations included hospitalised medical, surgical, and palliative patients. No trial reported on duration of delirium. Antipsychotic treatment did not reduce delirium severity compared to nonantipsychotic drugs (standard mean difference (SMD) -1.08, 95% CI -2.55 to 0.39; four studies; 494 participants; very low-quality evidence); nor was there a difference between typical and atypical antipsychotics (SMD -0.17, 95% CI -0.37 to 0.02; seven studies; 542 participants; low-quality evidence). There was no evidence antipsychotics resolved delirium symptoms compared to nonantipsychotic drug regimens (RR 0.95, 95% CI 0.30 to 2.98; three studies; 247 participants; very low-quality evidence); nor was there a difference between typical and atypical antipsychotics (RR 1.10, 95% CI 0.79 to 1.52; five studies; 349 participants; low-quality evidence). The pooled results indicated that antipsychotics did not alter mortality compared to nonantipsychotic regimens (RR 1.29, 95% CI 0.73 to 2.27; three studies; 319 participants; low-quality evidence) nor was there a difference between typical and atypical antipsychotics (RR 1.71, 95% CI 0.82 to 3.35; four studies; 342 participants; low-quality evidence). No trial reported on hospital length of stay, hospital discharge disposition, or health-related quality of life. Adverse event reporting was limited and measured with inconsistent methods; in those reporting events, the number of events were low. No trial reported on physical restraint use, long-term cognitive outcomes, cerebrovascular events, or QTc prolongation (i.e. increased time in the heart’s electrical cycle). Only one trial reported on arrhythmias and seizures, with no difference between typical or atypical antipsychotics. We found antipsychotics did not have a higher risk of extrapyramidal symptoms (EPS) compared to nonantipsychotic drugs (RR 1.70, 95% CI 0.04 to 65.57; three studies; 247 participants; very-low quality evidence); pooled results showed no increased risk of EPS with typical antipsychotics compared to atypical antipsychotics (RR 12.16, 95% CI 0.55 to 269.52; two studies; 198 participants; very low-quality evidence). Authors’ conclusions: There were no reported data to determine whether antipsychotics altered the duration of delirium, length of hospital stay, discharge disposition, or health-related quality of life as studies did not report on these outcomes. From the poor quality data available, we found antipsychotics did not reduce delirium severity, resolve symptoms, or alter mortality. Adverse effects were poorly or rarely reported in the trials. Extrapyramidal symptoms were not more frequent with antipsychotics compared to nonantipsychotic drug regimens, an…

Characterization of free and bound volatile compounds in six Ribes nigrum L. blackcurrant cultivars

This study investigated the profiles of free and bound volatile compounds of six currant cultivars grown in China. Results showed that 166 free and 111 bound volatiles were found in these cultivars with esters and terpenoids as the major volatiles. Additionally, 10 hydroxy esters were detected in these cultivars for the first time. Floral, fruity, and sweet flavors appeared to be the feature aroma in these cultivars, which resulted from the contribution of 17 volatiles. Principal component analysis indicated the cultivar ?Fertodi?, ?Risagar? and ?Liangye? had the similar profiles of free and bound volatile compounds, whereas the cultivar ?Brodtrop? and ?Yadrionaya? exhibited the similarity on their free and bound volatiles. The cultivar ?Sofya? showed a different volatile composition. Cluster analysis revealed the cultivar ?Fertodi?, ?Risagar?, and ?Liangye? had the similar profiles of free and bound volatile compounds, whereas the similar free and bound volatile compositions were observed in the cultivar ?Sofya? and ?Yadrionaya?. This study could provide useful information on quality control of commercial currant products.

Thiazole and Isothiazole Ring?Containing Compounds in?Crop Protection

Organic compounds containing five-membered aromatic heterocyclic rings play an important role in life science. Among them thiazole and isothiazole heterocycles are present in many pharmaceutical drugs and crop protection compounds and have sparked over past years an enormous interest on these scaffolds. In agrochemicals these moieties are found in 11 commercial products as well as in two development compounds. A thiazole moiety is present in seven currently marketed agrochemicals, namely the insecticides thiamethoxam and clothianidin, the fungicides thiabendazole, thifluzamide, ethaboxam, and oxathiapiprolin, and the nematicide fluensulfone, as well as in the development compound dicloromezotiaz. One compound, the fungicide isotianil, contains an isothiazole ring and three compounds a benzothiazole ring, namely the fungicide benthiavalicarb and the herbicides methabenzthiazuron and mefenacet. A benzisothiazole ring is not yet present in any commercial product, however, is found in the former nematicide development compound benclothiaz. Interestingly thiazole and isothiazole heterocycles are much less frequently found in agrochemicals than pyridine and pyrazole despite their bioisosteric relationship, which may indicate that these heterocycles have still not been explored to their full scope in crop protection lead discovery and optimization. Detailed information on the discovery, synthesis, and the structure?activity relationships of thiazole- and isothiazole-containing agrochemicals is provided in this review.

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 272-16-2 is helpful to your research. Application of 272-16-2
