Synthesis, Docking Studies, Admet Prediction, And Antimicrobial Evaluation Of Coumarin-Oxadiazole Hybrids, Fabin Asmath Maziyuna, Abhishek Kumar, Pankaj Kumar

The Thai Journal of Pharmaceutical Sciences

The overuse and misuse of marketed antimicrobial agents developed drug resistance, which has become a significant problem worldwide. A series of new coumarinyl-oxadiazole Schiff base derivatives were designed and synthesized. These synthesized molecules synthesis of coumarinyl-oxadiazole schiff base derivatives (FP1-FP7) were characterized using Infrared spectroscopy, proton nuclear magnetic spectroscopy, and mass spectroscopy and evaluated for their antibacterial potential against Gram-negative (Escherichia coli, Pseudomonas aeruginosa) and Gram-positive (Bacillus subtilis, Staphylococcus aureus) bacterial strain by measuring minimum inhibitory concentration values. Among the synthesized compounds, FP6 was found to be the best antibacterial agent having concentration values of 3.12 and 6.25 μg/ml against …
