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/.

Effect of Lactobacteria on Bioactive Peptides and Their Sequence Identification in Mature Cheese.

An in silico study that featured the effect of starter cultures on the bioactivity and other health benefits of peptides in semi-hard cheese is presented in this contribution. Model Caciotta-type cheese samples were obtained in laboratory conditions in two variations. Sample A included starter cultures of subsp.

Computational Binding Analysis of Ethyl 3,3,5,5-Tetracyano-2-Hydroxy-2-Methyl-4,6-Diphenylcyclohexane-1-Carboxylate in Calf Thymus DNA.

In the present paper, several computational binding analyses were performed on ethyl 3,3,5,5-tetracyano-2-hydroxy-2-methyl-4,6-diphenylcyclohexane-1-carboxylate which was newly synthesized by three-component condensation of benzaldehyde with ethyl acetoacetate and malononitrile in the presence of trichloroacetic acid, and the structure was finally proved by X-ray analysis. The visualization of molecular interaction was carried out through Hirshfeld surface analysis and ESP. The atomic charges, HOMO, LUMO, and electrostatic potential were also studied to explore the insight of the molecule deeper, and then, natural bonding orbitals (NBO) and non-linear optical properties (NLO) were calculated to reveal the interactions that happen to be between the filled and vacant orbitals.

Molecular docking study and molecular dynamics simulation of ethyl 3,5-diphenyl-1H-pyrrole-2-carboxylate and (Z)-ethyl-2-(3-oxo-1,3-diphenylprop-1-enylamino)acetate.

The present analysis has been performed in the wet-lab and computational environments. First, the synthesis of the latest heterocyclic compounds containing the alkyl organic compound fragment of acetate and glycine acid were obtained and then their crystal structure and biological activity were studied. (Z)-ethyl-2-(3-oxo-1,3-diphenylprop-1-enylamino) acetate (1) was initially retrieved on the supported reaction of dibenzene gas with glycine alkyl organic compound-complex within the presence of Y(OTF) catalyst in liquid medium.
