In vitro study reveals moderate antibacterial activity of novel thiazole Schiff bases against bacterial pathogens, indicating potential utility for antimicrobial drug optimization.

Key Points

Design, synthesize, and evaluate the antimicrobial activity and molecular docking profiles of novel Schiff base derivatives built upon a 2-amino-4-methylthiazole-5-carboxamide framework.
Synthesized derivatives by condensing 2-amino-N-(2-((2,4-dimethylphenyl)thio)phenyl)-4-methylthiazole-5-carboxamide with diverse aldehydes, confirming structures via MS, 1H NMR, 13C NMR, and IR spectroscopy.
Evaluated in vitro antibacterial efficacy to determine minimum inhibitory concentration (MIC) against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus.
Performed computational molecular docking against the bacterial DNA gyrase enzyme to assess theoretical ligand binding affinities.
Analogs 1c, 1f, and 1i demonstrated antibacterial activity against Gram-negative E. coli, each with an MIC of 62.5 µg/mL.
Analogs 1d and 1g showed inhibitory activity against P. aeruginosa and S. aureus, respectively, each with an MIC of 62.5 µg/mL.
Molecular docking of analog 1c into DNA gyrase showed a binding energy of −9.1 kcal/mol, corroborating the biological antibacterial findings.
