The synthesis of five-membered rings using fluoromethylene transfer chemistry is an attractive method for building fluorinated products of high value. This work demonstrates for the first time that one-fluorine-one-carbon modification of a substrate could be a viable strategy to access monofluorinated five-membered rings. The synthetic methodology was developed to access monofluorinated isoxazoline-N-oxides in one step starting from substituted 2-nitroacrylates using fluoromethylsulfonium reagents.

Safety of Benzyl Alcohol. I found the field of Dermatology very interesting. Saw the article Study of the composition of 140 shampoos: similarities and differences depending on the sales channel used published in 2019.0, Reprint Addresses Coiffard, L (corresponding author), Nantes Atlantique Univ, Univ Nantes, LPiC, MMS,EA2160,Fac Pharm, 9 Rue Bias, F-44000 Nantes, France..

Background: Shampoo is a hair care product designed to clean the skin and hair of the scalp. Among the ingredients that go into the making of a shampoo are detergents, conditioners, thickeners, sequestering agents, pH adjusters, preservatives, and active ingredients such as anti-dandruff agents. Objectives: The purpose of this study was to identify the composition of 140 shampoos available in pharmacies, in stores of a mass-market chain, or from mail-order retailers. Forty-one shampoos were advertised as gentle, 12 as specially formulated for infants, 35 as anti-dandruff, and 52 without any particular claim. Materials and Methods: We analysed the cleansing base, preservatives, and anti-dandruff agents when relevant and identified the allergens regardless of whether or not they are listed under Regulation (EC) No. 1223/2009 as one of the 26 regulated substances. Results: We discovered that unlike shampoos sold in stores of a mass-market chain and those available from mail-order retailers, those sold in pharmacies expose users to some of the 26 substances listed under Regulation (EC) No. 1223/2009. We also determined that baby shampoos sold in pharmacies are allergen-free. Regarding anti-dandruff formulations, the largest variety of active ingredients was found in shampoos sold in pharmacies. Overall, the most common active ingredients were olamines, zinc pyrithione, azoles, selenium disulphide, and plant extracts. Conclusion: Shampoos sold in pharmacies appear to contain fewer allergens listed under Regulation (EC) No. 1223/2009 compared to those sold elsewhere.

Cerebral amyloid angiopathy (CAA) commonly found in the aged is pathologically characterized by beta-amyloid (A beta) deposition in the walls of arteries and capillaries of brain. In this study, four flexible multidentate benzyldiamine derivatives as potential probes for cerebrovascular A beta deposition were designed and synthesized. In in vitro inhibition assays, the ligands 18-21 displayed high affinities for A beta aggregates with K-i values of 1.45 +/- 0.53 nM, 1.68 +/- 0.35 nM, 1.16 +/- 0.23 nM and 1.72 +/- 0.19 nM, respectively. A significant improvement in the binding affinity over the monomer, compounds 9-12 or benzyldiamine derivatives, demonstrated the applicability of the multidentate approach. The underlying mechanism of these novel A beta agents was explored by molecular docking technique, which theoretically verified the high affinities of the multidentate benzyldiamine derivatives for A beta aggregates. Moreover, the molecular masses of the ligands 18-21 are more than 700 Dalton, which are believed to be hardly capable of penetrating blood brain barrier. In this regard, these ligands could be used to distinguish CAA from Alzheimer’s disease which is another A beta-related disorder disease. To convert these ligands to positron emission tomography imaging agents, we attempted to radiosynthesize [F-18]18. Though the radiolabeling was not very successful, the preliminary results suggested that these newly proposed multidentate benzyldiamine derivatives may be used as potential A beta imaging agents in cerebral amyloid angiopathy.

An online survey was conducted to compare the safety, tolerability and reactogenicity of available COVID-19 vaccines in different recipient groups. This survey was launched in February 2021 and ran for 11 days. Recipients of a first COVID-19 vaccine dose >= 7 days prior to survey completion were eligible. The incidence and severity of vaccination side effects were assessed. The survey was completed by 2002 respondents of whom 26.6% had a prior COVID-19 infection. A prior COVID-19 infection was associated with an increased risk of any side effect (risk ratio 1.08, 95% confidence intervals (1.05-1.11)), fever (2.24 (1.86-2.70)), breathlessness (2.05 (1.28-3.29)), flu-like illness (1.78 (1.51-2.10)), fatigue (1.34 (1.20-1.49)) and local reactions (1.10 (1.06-1.15)). It was also associated with an increased risk of severe side effects leading to hospital care (1.56 (1.14-2.12)). While mRNA vaccines were associated with a higher incidence of any side effect (1.06 (1.01-1.11)) compared with viral vector-based vaccines, these were generally milder (p < 0.001), mostly local reactions. Importantly, mRNA vaccine recipients reported a considerably lower incidence of systemic reactions (RR < 0.6) including anaphylaxis, swelling, flu-like illness, breathlessness and fatigue and of side effects requiring hospital care (0.42 (0.31-0.58)). Our study confirms the findings of recent randomised controlled trials (RCTs) demonstrating that COVID-19 vaccines are generally safe with limited severe side effects. For the first time, our study links prior COVID-19 illness with an increased incidence of vaccination side effects and demonstrates that mRNA vaccines cause milder, less frequent systemic side effects but more local reactions.

The ligand activated transcription factor, aryl hydrocarbon receptor (AhR) emerged as a critical regulator of immune and metabolic processes in the gastrointestinal tract. In the gut, a main source of AhR ligands derives from commensal bacteria. However, many of the reported microbiotaderived ligands have been restricted to indolyl metabolites. Here, by screening commensal bacteria supernatants on an AhR reporter system expressed in human intestinal epithelial cell line (IEC), we found that the short chain fatty acid (SCFA) butyrate induced AhR activity and the transcription of AhRdependent genes in IECs. We showed that AhR ligand antagonists reduced the effects of butyrate on IEC suggesting that butyrate could act as a ligand of AhR, which was supported by the nuclear translocation of AhR induced by butyrate and in silico structural modelling. In conclusion, our findings suggest that (i) butyrate activates AhR pathway and AhR-dependent genes in human intestinal epithelial cell-lines (ii) butyrate is a potential ligand for AhR which is an original mechanism of gene regulation by SCFA.

Enantioselective alpha-aminomethylation of carbonyl compounds constitutes a powerful protocol for introducing aminomethyl groups to simple organic molecules. However, current strategies rely on nucleophile-based enantioselective activation with inherently activated substrates only, and enantioselective protocol based on the activation of in situ-generated unstable formaldimines remains elusive, probably owing to their unstable nature and the lack of steric environment for efficient stereocontrols. Here, based on a rhodium/chiral phosphoric acid cooperative catalysis, we achieved an enantioselective three-component reaction of alpha-diazo ketones with alcohols and 1,3,5-triazines. A dual hydrogen bonding between the chiral phosphoric acid catalyst and two distinct active intermediates was proposed to be crucial for the efficient electrophile-based enantiocontrol. A series of chiral beta-amino-alpha-hydroxy ketones including those derived from simple aliphatic alcohols, allylic alcohol, propargyl alcohol, complicated natural alcohols and water could all be prepared in high efficiency and enantioselectivity.

Jujube (Ziziphus jujuba Mill.) extract has been commonly used as a flavoring ingredient due to its unique aroma. In this study, solid phase micro extraction method was used to extract the volatile compounds in fresh jujube, with the aid of GC-MS for further chemical separation and identification. As a result, 33 volatile compounds, including aldehydes, alcohols, acids, ketones and esters, were identified. Among them, hexanal (276.5-1314 mu g/100g FW), (E)-2-hexanal, (145.1-1876 mu g/100g FW), nonanal (188.2-1047 mu g/100g FW), and n-decanoic acid (58.42-1268 mu g/100g FW) were found to be the major volatile compounds in fresh jujube fruit. Based on the type and amounts of the volatile compounds, 15 Chinese jujube cultivars were divided into 5 clusters through hierarchical cluster analysis and principal component analysis (PCA). Fiver clusters include cluster 1 (LB, HP, LZ, NP, JS, PZ, and YL), cluster 2 (BJ, DB), cluster 3 (PB, BZ, JD and XZ), cluster 4 (JB) and cluster 5 (YZ). According to the PCA, the clusters 1, 2 and 3 could not be discriminated from each other, but clusters 4 and 5 could be separated very well from each other.

To identify novel adenosine receptor (AR) ligands based on the chalcone scaffold, herein the synthesis, characterization and in vitro and in silico evaluation of 33 chalcones (15-36 and 37-41) and structurally related compounds (42-47) are reported. These compounds were characterized by radioligand binding and GTP shift assays to determine the degree and type of binding affinity, respectively, against rat (r) A(1) and A(2A) ARs. The chalcone derivatives 24, 29, 37 and 38 possessed selective A(1) affinity below 10 mu M, and thus, are the most active compounds of the present series; compound 38 was the most potent selective A(1) AR antagonist (K-i (r) = 1.6 mu M). The structure-affinity relationships (SAR) revealed that the NH2-group at position C3 of ring A of the chalcone scaffold played a key role in affinity, and also, the Br-atom at position C3 ‘ on benzylidene ring B. Upon in vitro and in silico evaluation, the novel C3 amino-substituted chalcone derivative 38-that contains an alpha,ss-unsaturated carbonyl system and easily allows structural modification-may possibly be a synthon in future drug discovery.
