In vitro and in silico studies reveal potent antimicrobial effects of isatin derivatives, indicating potential for addressing antibiotic resistance.

The study aims to develop novel antimicrobial agents to combat multidrug-resistant bacteria.
Designed and synthesized novel isatin derivatives via condensation reaction to form Schiff bases.
Confirmed structures using 1H and 13C NMR spectroscopy and ESI mass spectrometry.
Evaluated in vitro antimicrobial activity against various bacterial strains including E. coli and S. aureus.
Conducted in silico molecular docking studies to assess binding affinity toward target protein.
Compound SP2 showed the highest antimicrobial activity with a MIC of 0.88–1.05 µmol/mL and a zone of inhibition of 22–25 mm.
SP2 exhibited strong antioxidant activity with an IC50 of 39.29 µg/mL in the DPPH radical scavenging assay.
Molecular docking studies revealed a binding affinity of –9.9 kcal/mol for SP2 toward the target protein.

Panda et al. (2026) studied this question.
