SYNTHESIS, BIOLOGICAL EVALUATION AND MODELING STUDIES OF 2-(4-((1H-1,2,3-TRIAZOL-4-YL)METHOXY)PHENYL)BENZO[D]OXAZOLE AND 2-(4-((2-ALKYL-2H-TETRAZOL-5-YL)METHOXY)PHENYL) BENZO[D]OXAZOLES AS A NOVEL ANTIMICROBIAL AGENTS

Abstract

ABSTRACT A series of triazole (6a-f) and tetrazole (7a-f) derivatives were synthesized and their structures were confirmed by IR, 1HNMR and mass spectroscopic studies. All the compounds have been screened for their antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli and antifungal activity against Aspergillus fumigates Aspergillus niger and Candida albicans. Evaluation of antimicrobial activity considering the MIC value calculated by the serial dilution method revealed that several compounds exhibits good to moderate activity. Further to understand the interaction of the compounds with the bacterial and fungal protein receptor binding sites, docking studies are conducted using biotin protein ligase (BPL) (3V7R) from Staphylococcus aureus and dihydrofolate reductase (DHFR) (PDB ID 4HOF) from Candida albicans. Among the all compounds, compound 6d of triazole derivative and compound 7f of tetrazole derivative showed high docking energy. This investigation has open up the scope for development of a new class of antimicrobial agents. KEYWORDS: Benzoxazole, Triazole, Tetrazole, Molecular Docking and Antimicrobial activity
