A series of methyl sulfanyl/methyl sufonyl substituted 2,3-diaryl-2,3- dihydro-1H-quinazolin-4-one were designed using analogue-based design, scaffold hopping and shape similarity matching. The designed compounds were synthesized in 2-3 steps with simple chemistry and screened by ovine cyclooxygenases (COXs) inhibitory assay and carrageenan-induced rat paw edema assay. Among the screened compounds, two compounds exhibited 100% cyclooxygenase-2 (COX-2) inhibitory potency without showing cycloxygenase-1 (COX-1) inhibition at 20 μM. The compounds also showed promising in vivo anti-inflammatory potential. A structure-activity relationship within the dataset was established by correlating the effect of aromatic ring substituent constants, structural variables and physico-chemical descriptors with in vivo anti-inflammatory activity. Molecular docking studies were also performed on the title compounds to study the binding interactions to COX-2 active site residues. The experimentally determined COX-2 inhibitory activity was found moderately correlating with binding modes predicted for compounds by Glide XP dock scoring function. The 2,3-diaryl-2,3-dihydro-1H-quinazolin-4-one pharmacophore reported herein should be a new lead for further development of novel non-steroidal anti-inflammatory agents.

A highly efficient Au/Ag-Mo nano-rods catalyst was prepared for the one-pot synthesis of imine and amine using equal molar ratio of nitrobenzene and alcohol as starting materials, and bio-based glycerol as the hydrogen source. The reaction mechanism of the nitrobenzene reduction, amine and aldehyde coupling, and imine reduction was explored.

A series of 1,5-diarylimidazoles with 4-methylsulfonylphenyl group were prepared and evaluated for the inhibitory activities against COX-2 catalyzed PGE2 production from LPS-induced RAW 264.7 cells. Most of synthesized 1,5-diarylimidazoles exhibited strong inhibitory activities regardless of the position of the 4-methylsulfonylphenyl group. The 1,5-diarylimidazoles with a halogen atom (3c-3h, 3n-3p) gave mostly excellent inhibitory activities regardless of the position and species of the halogen atom. Whereas the 1,5-diarylimidazoles with two fluorine atoms (3k, 3l, 3r, 3s) showed rather reduced inhibitory activities.
