Abstract

In the present work, we have reported the theoretical and biological activities of some imidazole (MIPBD, CMIBP, MIBPBD) derivatives. Here, the synthesis of one novel substituted imidazo-amino pyridinyl derivative (MIPBD) has also been reported. The structure of this compound was identified by NMR and mass spectroscopy. Molecular modeling studies have confirmed that CMIBP (ΔE= 0.16508 eV) is more stable than others. Antibacterial investigation exhibited good to excellent activity for all these compounds against two tested bacterial strains (S. aureus and E. coli). Moreover, molecular docking studies were carried out, which was consistent with experimental studies. The results motivate us for further studies of imidazole derivatives which will be helpful for the development of novel antibacterial agents.
