The impact of SO2 on wine flavanols and indoles in relation to wine style and age

Wine has one of the broadest chemical profiles, and the common oenological practice of adding the antioxidant and antimicrobial sulfur dioxide has a major impact on its metabolomic fingerprint. In this study, we investigated novel discovered oenological reactions primarily occurring between wine metabolites and sulfur dioxide. The sulfonated derivatives of epicatechin, procyanidin B2, indole acetic acid, indole lactic acid and tryptophol were synthesized and for the first time quantified in wine. Analysis of 32 metabolites in 195 commercial wines (1986-2016 vintages) suggested that sulfonation of tryptophan metabolites characterised white wines, in contrast to red wines, where sulfonation of flavanols was preferred. The chemical profile of the oldest wines was strongly characterised by sulfonated flavanols and indoles, indicating that could be fundamental metabolites in explaining quality in both red and white aged wines. These findings offer new prospects for more precise use of sulfur dioxide in winemaking.

An Iridium(I) N-Heterocyclic Carbene Complex Catalyzes Asymmetric Intramolecular Allylic Amination Reactions

A chiral iridium(I) N-heterocyclic carbene complex was reported for the first time as the catalyst in the highly enantioselective intramolecular allylic amination reaction. The current method provides facile access to biologically important enantioenriched indolopiperazinones and piperazinones in good yields (74?91 %) and excellent enantioselectivities (92?99 % ee). Preliminary mechanistic investigations reveal that the C?H activation occurs at the position ortho to the N-aryl group of the ligand.

Anomalously short fluorescence lifetimes in jet cooled 4-hydroxyindole. Evidence for excited state tautomerism and proton transfer in clusters

Jet cooled fluorescence lifetimes following excitation of S1 origins have been measured for 4-hydroxyindole. The subnanosecond values obtained are anomalous compared to other substituted indoles, in particular 5-hydroxyindole. The short lifetimes are most likely related to excited state tautomerism in the bare 4-hydroxyindole. It was further found that one solvent molecule addition of triethylamine to 4-hydroxyindole is sufficient to induce excited state proton transfer, to a significantly greater extent than with 5-hydroxyindole.

Synthesis and biological evaluation of novel 4-azaindolyl-indolyl-maleimides as glycogen synthase kinase-3beta (GSK-3beta) inhibitors

A series of novel 4-azaindolyl-indolyl-maleimides were synthesized and evaluated for their GSK-3beta inhibitory activity. Most compounds exhibited high potency to GSK-3beta. Among them, compound 7c was the most promising GSK-3beta inhibitor. Preliminary structure-activity relationships were discussed based on the experimental data obtained and showed that different substituents on the indole ring and side chains at 1-position of indole had varying degrees of influence on the GSK-3beta inhibitory potency. In a cell-based functional assay, compounds 7c and 15a significantly reduced Abeta-induced Tau hyperphosphorylation by inhibiting GSK-3beta.

77Se and 125Te NMR spectroscopy on a selectivity study of organochalcogenanes with L-amino acids

The hypervalent selenium- and tellurium-containing compounds (halo-organoselenuranes and halo-organotelluranes) were treated with amino acids to evaluate their reactivity and chemoselectivity by 1H, 13C, 77Se and 125Te NMR spectroscopy. The study of forced thermal stability was performed and analyzed by NMR. The organotelluranes remained stable at temperatures around 60 C but in the case of organoselenuranes, there was formation of new products at 37 C as a result of halogen loss. 77Se and 125Te NMR spectroscopy has proved to be a very efficient and fast technique to evidence the high selectivity of organochalcogenanes against l-amino acids, specific to l-cysteine.
