|
Series of some novel nitrogen based Indole-2-one Schiff’s bases (4a-4j) were synthesized by a conventional method via Schiff’s bases mechanism. The Istain Schiff’s bases was made by combining substituted isatin with hydrazine hydrate in ethanol to generate a compounds 3a-3d, which was then reacted with terephthaldehyde and 5-amino pyrimidine to obtained final compounds. All the synthesized compounds gave a good yield between 76–88% and structure was confirmed by FT-IR, LC-MASS and 1H-NMR spectral analysis. The novel nitrogen based Indole-2-one Schiff’s bases are screened for antimicrobial activity using standard agar diffusion method and using four bacterial stains (Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Salmonella paratyphi). The most of the compounds such as 4a, 4d, 4e, 4h and 4j shows good activity against gram positive and gram negative bacteria. Finally, molecular docking studies were carried out by using AUTODOCK suite of MGL Tools by using Fgb1 receptor with PDB ID (3K4P). Among the docked ligands, compound 4a, 4d and 4h reported highest docking score (-9.8, -9.7 and -9.7).
