Synthesis, Characterization, Antimicrobial Activity and Molecular Docking Studies of New Benzimidazole, Benzoxazole, Imidazole and Tetrazole Derivatives

In the present research work, 12 new compounds, such as benzimidazole (3, 3a-c), benzoxazole(4), imidazole(5, 5a-c) and tetrazole(6, 6a-c) were synthesized. FT-IR, Proton NMR (1H), C-13-NMR, Mass spectral values were used to prove the structures of the compounds. The antimicrobial potential of the representative compounds was assessed using the Disc diffusion process. All the benzoxazole, benzimidazole, imidazole and tetrazole derivatives prepared in this investigation show good antimicrobial activity. However the antimicrobial activities of the compounds are less compared with standard drugs. Molecular docking studies have also done for the synthesized compounds all the compounds show hydrogen bond interactions with receptor protein.
