A practical, efficient and general method was developed for the deprotection of a variety of aromatic and aliphatic acetals to their corresponding catechol or diol derivatives using thiol immobilized on silica gel. This is an application for the well-known commercial solid-supported thiol (SiliaMetS Thiol). The procedure is mild and amenable to scale-up. It does not require inert atmosphere and clean conversions were observed. This method is applicable to substituted 1,3-benzodioxole and aliphatic acetals with different functionalities. It offers the advantage of a general route with high yield, which can be undertaken at ambient temperature.

Application of 53558-93-3, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.53558-93-3, Name is (R)-(-)-5-Oxotetrahydrofuran-2-carboxylicacid, molecular formula is C5H6O4. In a Article，once mentioned of 53558-93-3

This paper describes a novel approach to reassess the water status in vineyards based on compound-specific isotope analysis (CSIA) of wine volatile organic compounds (delta13CVOC/VPDB) and bulk carbon and nitrogen isotopes, and the C/N molar ratios of the wine solid residues (delta13CSR/VPDB, delta15NSR/Air-N2). These analyses link gas chromatography/combustion and elemental analysis to isotope ratio mass spectrometry (GC/C/IRMS, EA/IRMS). Field-grown cultivars of Pinot Noir grapevines were exposed during six growing seasons (2009?2014) to controlled soil water availability, while maintaining identical the other environmental variables and agricultural techniques. Wines were produced from the grapes by the same oenological protocol. This permitted for the assessment of the effects in the biochemistry of wines solely induced by the changes in the plant-soil water status. This mimicked the more recurrent and prolonged periods of soil water deficiency due to climate changes. Water stress in grapevine was assessed by the measurement of the predawn leaf water potential (Psipd) and the stable carbon isotope composition of the berry sugars during harvest (must sugars). For quantitation purposes and the normalization of the measured stable carbon isotope ratios of the VOCs, the wine samples were spiked with three standard compounds with known concentration and delta13CVPDB values. VOCs were extracted by liquid?liquid extraction and analyzed by gas chromatography/flame ionization detection (GC/FID), gas chromatography/mass spectrometry (GC/MS), and GC/C/IRMS. delta13C values were obtained for eighteen VOCs. The solid residues were obtained by freeze-drying wine aliquots and were analyzed for their C and N content and isotope composition by EA/IRMS. All the isotopic ratios (delta13CSR, delta15NSR, delta13CVOC) are highly correlated with the Psipd values, indicating that the proposed gas chromatography and isotope ratio mass spectrometry approach is a useful tool to assess the changes in the water status of grapevine cultivars in different terroirs. The combined analytical approach was used for the first time to complement the assessment of soil water availability effects on the grapevine. The delta13C values of the volatile compounds helped confirm (or establish) their main source(s) and biosynthetic pathway(s). Importantly, we also show for the first time that the combination of C/N and delta15N values of freeze-dried wines have an unexplored potential for the study of nitrogen dynamics in soil/grape/wine systems.

A series of 3-oxo-C12-HSL, tetramic acid, and tetronic acid analogues were synthesized to gain insights into the structural requirements for quorum sensing inhibition in Staphylococcus aureus. Compounds active against agr were noncompetitive inhibitors of the autoinducing peptide (AIP) activated AgrC receptor, by altering the activation efficacy of the cognate AIP-1. They appeared to act as negative allosteric modulators and are exemplified by 3-tetradecanoyltetronic acid 17, which reduced nasal cell colonization and arthritis in a murine infection model.

Cannabinoid type 2 (CB2) receptor continues to emerge as a promising drug target for many diseases and conditions. New tools for studying CB2 receptor are required to further inform how this receptor functions in healthy and diseased states. The alkyl indole scaffold is a well-recognised ligand for cannabinoid receptors, and in this study the indole C5-7 positions were explored for linker and fluorophore attachment. A new high affinity, CB2 receptor selective inverse agonist was identified (16b) along with a general trend of C5-substituted indoles acting as agonists versus C7-substituted indoles acting as inverse agonists. The indole C7 position was found to be the most tolerant to linker extension and resulted in a high affinity inverse agonist with a medium length linker (19). Although a high affinity fluorescent ligand for CB2 receptor was not identified in this study, the indole C7 position shows great promise for fluorophore or probe attachment.
