Synthesis, Characterization, DFT, and In Silico Investigation of Two Newly Synthesized β-Diketone Derivatives as Potent COX-2 Inhibitors.

Despite extensive genetic and biochemical characterization, the molecular genetic basis underlying the biosynthesis of β-diketones remains largely unexplored. β-Diketones and their complexes find broad applications as biologically active compounds. In this study, in silico molecular docking results revealed that two β-diketone derivatives, namely 2-(2-(4-fluorophenyl)hydrazono)-5,5-dimethylcyclohexane-1,3-dione and 5,5-dimethyl-2-(2-(2-(trifluoromethyl)phenyl)hydrazono)cyclohexane-1,3-dione, exhibit anti-COX-2 activities.

Crystal structure, Hirshfeld surface analysis and DFT study of (5,5',6,6')-6,6'-[ethane-1,2-diyl-bis(aza-nylyl-idene)]bis-{5-[2-(4-fluoro-phen-yl)hydra-zono]-3,3-di-methyl-cyclo-hexa-none} 2.5-hydrate.

The title compound, CHFNO·2.5HO, was obtained by condensation of 2-[2-(4-fluoro-phen-yl)hydrazono]-5,5-di-methyl-cyclo-hexan-1,3-dione with ethyl-enedi-amine in ethanol and crystallized as a 1:2.5 hydrate in space group 2/.

One-pot synthesis, X-ray crystal structure, and identification of potential molecules against COVID-19 main protease through structure-guided modeling and simulation approach.

Although antimicrobial resistance before the Covid-19 pandemic is a top priority for global public health, research is already ongoing on novel organic compounds with antimicrobial and antiviral properties in changing medical environments in connection with Covid 19. Thanks to the Biginelli reaction, which allows the synthesis of pyrimidine compounds, blockers of calcium channels, antibodies, antiviral, antimicrobial, anti-inflammatory, or antioxidant therapeutic compounds were investigated. In this paper, we aim to present Biginelli's synthesis, its therapeutic properties, and the structural-functional relationship in the test compounds that allows the synthesis of antimicrobial compounds.
