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.

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.

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.

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.

Comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC x GC-TOF-MS) was combined with conventional mono-dimensional GC-MS to differentiate Croatian virgin olive oils (VOO) according to variety and geographical origin, based on the profile of volatile aroma compounds isolated by HS-SPME. More than 1000 compounds were detected after untargeted profiling and 256 were identified or tentatively identified, providing one of the most detailed profiles of volatile aroma compounds in VOO up to date. Among them, 131 volatile compounds were significantly different across monovarietal VOOs, while 60 were found useful for the discrimination according to geographical origin. Many major lipoxygenase and minor non-lipoxygenase-generated compounds were shown to have discriminating ability with respect to both factors. Multivariate statistical analysis extracted twenty-one volatile markers with the highest discriminant power for varietal differentiation. The approach reported may have practical application in better understanding, defining, managing, and communicating the varietal or geographical typicity of monovarietal VOOs.

Described here is a titanocene-catalyzed reaction for the synthesis of acetals and hemiaminals from benzylic ethers and benzylic amines, respectively, with pendant epoxides. The reaction proceeds by catalysis in single-electron steps. The oxidative addition comprises an epoxide opening. An H-atom transfer, to generate a benzylic radical, serves as a radical translocation step, and an organometallic oxygen rebound as a reductive elimination. The reaction mechanism was studied by high-level dispersion corrected hybrid functional DFT with implicit solvation. The low-energy conformational space was searched by the efficient CREST program. The stereoselectivity was deduced from the lowest lying benzylic radical structures and their conformations are controlled by hyperconjugative interactions and steric interactions between the titanocene catalyst and the aryl groups of the substrate. An interesting mechanistic aspect is that the oxidation of the benzylic center occurs under reducing conditions.

Artificial photosynthesis of H2O2 from H2O and O-2, as a spotless method, has aroused widespread interest. Up to date, most photocatalysts still suffer from serious salt-deactivated effects with huge consumption of photogenerated charges, which severely limit their wide application. Herein, by using a phenolic condensation approach, carbon dots, organic dye molecule procyanidins and 4-methoxybenzaldehyde are composed into a metal-free photocatalyst for the photosynthetic production of H2O2 in seawater. This catalyst exhibits high photocatalytic ability to produce H2O2 with the yield of 1776 mu mol g(-1)h(-1) (lambda >= 420nm; 34.8mWcm(-2)) in real seawater, about 4.8 times higher than the pure polymer. Combining with in-situ photoelectrochemical and transient photovoltage analysis, the active site and the catalytic mechanism of this composite catalyst in seawater are also clearly clarified. This work opens up an avenue for a highly efficient and practical, available catalyst for H2O2 photoproduction in real seawater. It is a challenge to produce hydrogen peroxide in seawater by photocatalysis. Here, the authors design and synthesize a metal-free photocatalyst based on carbon dots with a salt-protective electron sink effect, which exhibits enhanced hydrogen peroxide photoproduction in real seawater.

Up to four different phases can be present in the heterogeneously catalyzed, liquid phase, aerobic oxidation of benzyl alcohol over Pt/TiO2. It is shown that the rate of benzyl alcohol oxidation is greatly enhanced upon addition of water to the initial reaction mixture but is not affected by the split between the two liquid phases. The rate of reaction correlates with the composition of water in the phase associated with the catalyst, i. e. the water-poor phase. Water may have various kinetic effects, e. g. a change in the distribution of surface species. It is argued on grounds of thermodynamic consistency that the liquid phase surrounding the catalyst is an intricate part of the catalyst in the aerobic benzyl alcohol oxidation over Pt/TiO2; water present in this liquid phase interacts with species on the surface altering the reaction kinetics.
