Chemical Transformation of Pyrazine Derivatives [PDF]
, 2022 Pyrazine is a group of N-containing heterocycle compounds found in both nature and synthetic drugs. In fact, the existence of the pyrazine ring as a basic framework in many drug compounds indicates that these compounds are important in drug development ...

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 ...

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 ...

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 ...

Synthesis and Electroluminescence of Thieno-[3,4-b]pyrazine-cored Molecule with Fluorinated Shell
, 2013 A thieno-[3,4-b]-pyrazine-based molecule, F-DTP, was designed and synthesized for application as a red emitter in non-doped organic light-emitting diodes. F-DTP was designed with thieno-[3,4-b]-pyrazine as the luminescent core and pentaphenylphenylene (i.
