ABSTRACT

Isatin and its derivatives exhibit a wide range of biological activities, including anticancer, antiviral, antibacterial, antifungal, anti-inflammatory, and antihistaminic effects. In this study, 16 N-substituted isatin derivatives have shown significant potential against bacterial infections. Molecular docking and modeling studies reveal that these derivatives interact effectively with targets like SARS-CoV-2 main protease (PDB IDs: 6VXX, 7V7Q, 7DF4, 7V8B). These interactions occur via hydrogen bonding and hydrophobic interactions, leading to promising activity against main protease. The structural modifications, including substitutions at C2, C3, and N positions, enhance the biological efficacy of isatin derivatives. This study synthesized and evaluated a library of isatin derivatives for their activity against Gram-Positive and Gram-negative microbial strains such as Staphylococcus aureus, Escherichia coli. The results suggest that these derivatives are promising candidates for further development as therapeutic agents are reflected in their minimal inhibitory concentration value.
