Synthesis and molecular docking studies of coumarin-imidazole conjugates as potential antimicrobial agents

110-125One-pot multi-component synthesis of tri and tetra-substituted coumarin-imidazole conjugates have been achieved in good to excellent yield under conventional and microwave methods in optimized catalyst condition. Further, they have been evaluated for antimicrobial activity against Gram positive Bacillus flexus and Gram negative Pseudomonas Spp. bacterial strains and two strains of fungi Scopulariopsis spp. and Aspergillus tereus organisms. The results of microbial activity are promising against tested organisms. The molecular docking study has been performed for all the compounds and docking scores are excellent. Synthesized compounds have been characterized by IR, NMR, mass and a few of them by single crystal X-ray analysis

Synthesis, in vitro biological evaluation and molecular docking study of coumarin-1,4-dihydropyridine derivatives as potent anti-inflammatory agents

The green chemistry approach provides for the synthesis of coumarin-1,4-dihydropyridine scaffolds 6a-o via sequential multicomponent reaction using catalytic amount of triethylamine (TEA). These new coumarin scaffolds have been successfully explored for the effective inflammatory as well as microbial infection inhibitors. The antimicrobial activity results of the title compounds have shown potent activity against both gram positive and gram negative bacterial, and fungal stains. Additionally, anti-inflammatory activity of all the compounds has been found to be quite promising in comparison with standard Diclofenac sodium. Furthermore, the in silico docking study has been performed for all the compounds with S. aureus DNA gyrase and cyclooxygenase-2 (PDB ID 4PH9). The computational results are in good agreement with the in vitro antibacterial and anti-inflammatory experimental results.
