摘要
A group of compounds containing pyran, pyrazole, and pyranopyrazole were synthesized (2–4) using a facile and convenient protocol. The structure of the synthesized compounds was elucidated by spectroscopic and elemental analysis. In vitro antimicrobial evaluation was also performed for all synthesized derivatives against human pathogenic bacterial strains such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Bacillus subtilis using chloramphenicol as a reference. It was depicted that compounds 3d, 4b displayed a high degree of inhibition against Bacillus subtilis and Staphylococcus aureus. Compounds 2d, 4f and 2d, 4e, 4f, and 4e had high inhibition effects against Escherichia coli and Pseudomonas aeruginosa, respectively. The molecular docking study was performed against S. aureus bacteria to rationalize the binding affinities and the feasible modes of interaction with the active site of tyrosyl-tRNA synthetase. It was found that the synthesized compounds were well fit into the binding site of tyrosyl-tRNA synthetase. The obtained results were in good accordance with the experimental data. The data obtained were promising candidates for further development of novel heterocyclic scaffolds as therapeutics with high efficacy biomedical precursors.
