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.

Quality Control of 3-Hydroxybenzaldehyde. The Name is 3-Hydroxybenzaldehyde. Through research, I have a further understanding and discovery of 100-83-4

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.

Formula: C7H8O. The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

Golgi endo-alpha-mannosidase (G-EM) catalyzes an alternative deglucosylation process for N-glycans and plays important roles in the post-endoplasmic reticulum (ER) quality control pathway. To understand the post-ER quality control mechanism, we synthesized a tetrasaccharide probe for the detection of the hydrolytic activity of G-EM based on a fluorescence quenching assay. The probe was labeled with an N-methylanthraniloyl group as a reporter dye at the non-reducing end and a 2,4-dinitrophenyl group as a quencher at the reducing end. This probe is hydrolyzed to disaccharide derivatives by G-EM, resulting in increased fluorescence intensity. Thus, the fluorescence signal is directly proportional to the amount of disaccharide derivative present, allowing the G-EM activity to be evaluated easily and quantitatively.

I found the field of Biotechnology & Applied Microbiology; Immunology; Microbiology; Pharmacology & Pharmacy very interesting.

InhA or enoyl-acyl carrier protein reductase of Mycobacterium tuberculosis (mtInhA), which controls mycobacterial cell wall construction, has been targeted in the development of antituberculosis drugs. Previously, our in silico structure-based drug screening study identified a novel class of compounds (designated KES4), which is capable of inhibiting the enzymatic activity of mtInhA, as well as mycobacterial growth. The compounds are composed of four ring structures (A-D), and the MD simulation predicted specific interactions with mtInhA of the D-ring and methylene group between the B-ring and C-ring; however, there is still room for improvement in the A-ring structure. In this study, a structure-activity relationship study of the A-ring was attempted with the assistance of in silico docking simulations. In brief, the virtual chemical library of A-ring-modified KES4 was constructed and subjected to in silico docking simulation against mtInhA using the GOLD program. Among the selected candidates, we achieved synthesis of seven compounds, and the bioactivities (effects on InhA activity and mycobacterial growth and cytotoxicity) of the synthesized molecules were evaluated. Among the compounds tested, two candidates (compounds 3d and 3f) exhibited superior properties as mtInhA-targeted anti-infectives for mycobacteria than the lead compound KES4.

A concise approach for the synthesis of structurally diverse indoles enabled by Rh-III-catalyzed switchable C2 C-H olefination and alkylation of N-quinolinyl indoles with alkenes as well as highly efficient C-H deuteration is described. The reaction can be conducted under practical reaction conditions, with a broad substrate scope and good tolerance of various functional groups. The potential value of this synthetic methodology is shown by the diverse late-stage modification of the products, thereby providing a straightforward route to access functionalized indoles, especially indole-based P,N ligands.

The Summary of main observation and conclusionStructure-reactivity study of a family of electrophilic monofluoromethylating reagents based on sulfonium ylide skeleton with different steric hindrance and electron-withdrawing properties was described. These studies led us to discover two highly reactive reagents 3 with a cyclic malonate backbone and 6 with an electron-poor 1,1,1,5,5,5-hexafluoropentane-2,4-dione backbone. The high reactivity of reagent 6 allowed to highly selectively access either C-monofluoromethylated or O-monofluoromethylated beta-ketoesters in high yields by the use of different bases. In addition, reactions of reagent 3 with a variety of nucleophiles including phenols, carboxylic acids, thiophenols or heteroaryl nucleophiles occurred in full conversion within 10 min at room temperature and the scopes for these reactions were reported in detail.
