1,3,4-Oxadiazole Derivatives : Synthesis, Characterization, Antimicrobial Potential, and Computational Studies

Abstract EN

We report the synthesis and biological assessment of 1,3,4-oxadiazole substituted 24 derivatives as novel, potential antibacterial agents.

The structures of the newly synthesized derivatives were established by the combined practice of UV, IR, 1H NMR, 13C NMR, and mass spectrometry.

Further these synthesized derivatives were subjected to antibacterial activity against all the selected microbial strains in comparison with amoxicillin and cefixime.

The antibacterial activity of synthesized derivatives was correlated with their physicochemical and structural properties by QSAR analysis using computer assisted multiple regression analysis and four sound predictive models were generated with good R2, R adj 2, and Fischer statistic.

The derivatives with potent antibacterial activity were subjected to molecular docking studies to investigate the interactions between the active derivatives and amino acid residues existing in the active site of peptide deformylase to assess their antibacterial potential as peptide deformylase inhibitor.
