The search for new antibiotics is becoming more and more indispensable.Methods: Design and synthesis of isatin derivatives as surrogates of SB-239629, a bacterial tyrosine-tRNA synthetases (TyrRS) inhibitor. The newly synthesized compounds were screened for their antimicrobial and antibiofilm activities. Docking studies were used to investigate potential binding modes of these compounds with TyrRS.Results and Discussion: Newly synthesized isatin-decorated thiazole derivatives (7b, 7d, and 14b) have shown potent antimicrobial activities against E. coli, a representative of gram-negative bacteria. Also, 7f showed the best activity against ...
