Jin, Bo published the artcileSynthesis and biological evaluation of 3-(pyridine-3-yl)-2-oxazolidinone derivatives as antibacterial agents, Synthetic Route of 1079179-12-6, the main research area is pyridinyl oxazolidinone preparation mol docking antibiofilm antibacterial activity; 3-(pyridine-3-yl)-2-oxazolidinone; antibacterial activity; biofilm formation inhibitory activity; drug resistance development; molecular docking.

In this research, a series of 3-(pyridine-3-yl)-2-oxazolidinone derivatives I [R = (pyridin-3-yl)carbonyl, Me, N-cyclohexylcarbamoyl, etc.], II (X = F, H) was designed, synthesized, and evaluated for in vitro antibacterial activity, which included bacteriostatic, morphol., kinetic studies, and mol. docking. The results demonstrated that compounds II [R = cyclohexanecarbonyl, (2E)-3-(furan-2-yl)prop-2-enoyl (III), (2E)-3-(pyridin-3-yl)prop-2-enoyl, N-(4-chlorophenyl)carbamoyl; X = F] exhibited strong antibacterial activity similar to that of linezolid toward five Gram-pos. bacteria. After observing the effect of the drug on the morphol. and growth dynamics of the bacteria, the possible modes of action were predicted by mol. docking. Furthermore, the antibiofilm activity and the potential drug resistance assay were proceeded. These compounds exhibited universal antibiofilm activity and compound III showed significant concentration-dependent inhibition of biofilm formation. Compound III also showed a stable effect on S. pneumoniae (ATCC 49619) with less drug resistance growth for 15 days, which is much longer than that of linezolid. Overall, these results can be used to guide further exploration of novel antimicrobial agents.
