• N2-(Arylacetyl)glycinanilide as novel potent antibacterial agent.
• Significant improvement of activity against Gram-negative bacterial strains.
• The most potent compound showing 3-fold more potency than penicillin G.
Tyrosyl-tRNA synthetase (TyrRS), an essential enzyme in bacterial protein biosynthesis, is an attractive therapeutic target for finding novel antibacterial agents, and a series of N2-(arylacetyl)glycinanilides has been herein synthesized and identified as TyrRS inhibitors. These efforts yielded several compounds, with IC50 in the low micromolar range against TyrRS from Staphylococcus aureus. Out of the obtained compounds, 3ap is the most active and exhibits excellent activity against both Gram-positive (S. aureus) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacterial strains. In comparison with the parent scaffold 3-arylfuran-2(5H)-one, N2-(arylacetyl)glycinanilide significantly improved the potency against Gram-negative bacterial strains, indicating that this scaffold offers a significant potential for developing new antibacterial drugs.
