Sharing of Pyrazine Semiochemicals between Genera of Sexually Deceptive Orchids
Natural Product Communications, 2013 It has recently been discovered that novel di-, tri- and tetra- substituted pyrazines are semiochemicals in Drakaea , an orchid genus that secures pollination by the sexual deception of male thynnine wasps.

The Impact of Glycation on Protein Digestibility
ChemFoodChem, EarlyView.Schematic overview of how protein glycation affects digestibility and downstream nutritional consequences. Glycation‐derived structural modifications reduce protease accessibility, leading to limited hydrolysis and altered peptide generation. These changes decrease amino acid bioavailability and may subsequently contribute to microbiome alterations ...

Chemistry – A European Journal, EarlyView.Combining the chiral bispidine ligand L1 with MnCl2 affords coordination polymers (CPs) with an unusual topology for this family of compounds, consisting of orthogonally packed ribbon‐like one‐dimensional (1D) chains. Their behavior was investigated through single‐crystal‐to‐single‐crystal exchange with aromatic volatile organic compounds (VOCs) and ...

GC–MS analysis of alkylpyrazines in the pyrolysis oils of silica-polyethylenimine CO2 sorbents
Journal of Chromatography OpenSolid sorbents based on silica and polyethyleneimine (PEI) are intensively investigated in the field of carbon capture and storage (CCS). Pyrolysis was proposed as a thermal process to recover the pure silica from exhausted sorbents and convert PEI into ...

Chemistry – A European Journal, EarlyView.The reactions between tetra(pyridin‐4‐ylthio)tetrathiafulvalene and Br2/I2/ICl/IBr led to a variety of products, including a rare example of neutral 1:4 CT adduct and ionic products showing supramolecular cage motifs at (tri)halide templates. The nature of the reaction products was elucidated based on XRD analysis, Raman spectroscopy and QTAIM, NCI ...

Simultaneous determination of 19 pyrazines and furans compounds in vintage sauce-flavor Baijiu by GC-MS/MS [PDF]
Zhongguo niangzaoBased on gas chromatography-triple quadrupole tandem mass spectrometry (GC-MS/MS), a method for simultaneous determination of 19 pyrazines and furans compounds in vintage sauce-flavor (Jiangxiangxing) Baijiu was established, and the contents of pyrazines

A Stable Isopterin Mimic of a Potent Bacterial Stimulant of T Cells
Chemistry – A European Journal, EarlyView.A microbial metabolite covalently binds immunological protein MR1 to potently activate specific lymphocytes called MAIT cells, but it is too unstable for biological applications. Here, using synthesis, assays, protein crystallography, and computer modelling, we report a water‐stable analogue that activates reporter cells expressing the MAIT T cell ...

Chemistry – A European Journal, EarlyView.A unimolecular polyampholytic graft copolymer matrix provides a protective confinement for an electrostatically embedded tetrapyridophenazine‐bridged heterodinuclear Ru‐Pt hydrogen evolving photocatalyst. The matrix slows the degradation kinetics of the catalyst and at the same time does not hinder its repair by ammonium persulfate.
