Four new oxadiazole derivatives, 5-(2-chlorophenyl)-1, 3, 4-oxadiazole-2-amine, 5-(3-nitrophenyl)-1, 3, 4-oxadiazole-2-amine, 4-(5-amino-1, 3, 4-oxadiazole-2-yl)phenol, 5-(3,4-dimethoxyphenyl)-1, 3, 4-oxadiazole-2-amine have been synthesized, characterized and studied for in-vitro antimicrobial activities. The antibacterial studies is carried out against bacteria E.coli, Bacillus subtilis, Micrococcus letteus and the anti-fungal studies is carried out against fungus candida albicans, Sacromyces cervesiae at concentrations 50μg/ml, 100 μg/ml and 150μg/ml. The potency of the derivatives is analysed against standard antibiotic drug ampicillin at 100μg/ml. Compounds 5-(2-chlorophenyl)-1, 3, 4-oxadiazole-2-amine and 5-(3,4-dimethoxyphenyl)-1, 3, 4-oxadiazole-2-amine are found more effective than ampicillin, which may be explored as new analogues in antibiotic category.
