Our computer-aided protein-ligand docking test using Autodock Vina software allowed to reveal the potential of few α- and β-diketones from plants alternative living organisms as covalent ligands for proteins coronavirus SARS-CoV-2 – a causative agent COVID-19. It has been established that values energy binding (docking score, Ebind, kcal/mol) less than –7.5 distances ligands’ carbonyl groups si...
The synthesis and characterization of "2 + 1" complexes of the [M(CO)(3)](+) (M = Re, (99m)Tc) core with the β-diketones acetylacetone (complexes 2, 8) and curcumin (complexes 5, 10 and 6, 11) as bidentate OO ligands, and imidazole or isocyanocyclohexane as monodentate ligands is reported. The complexes were synthesized by reacting the [NEt(4)](2)[Re(CO)(3)Br(3)] precursor with the β-diketone t...
A series of new triphenylamine functionalized β-diketones 1–3 and their difluoroboron complexes 1B–3B were synthesized. They exhibited strong intramolecular charge transfer (ICT) emission. It was found that their self-assembling properties depended on the molecular structures. For example, compounds 1 and 1B, in which only one β-diketone or difluoroboron β-diketone unit was linked to triphenyla...
The chemical composition of the lipids in wheat straw was studied in detail by gas chromatography and mass spectrometry. Important discrepancies with the data reported in previous papers were found. The predominant lipids identified were series of long-chain free fatty acids (25% of total extract), followed by series of free fatty alcohols (ca. 20%). High molecular weight esters of long chain f...
An unusual radical fragmentation of an unstrained cyclohexane structure was observed leading to complex 1,2-diketones.
