Abstract

Synthesis of a series of various 2, 5-disubstituted-1, 3, 4-oxadiazole derivatives (7a-7v) have been done previously. These novel synthesized derivatives (7a-7v) have been tested for their antibacterial activity against Gram +ve S. aureus and Gram -ve E. Coli bacterias by broth dilution method. A comparative study has been done for all derivatives.  Based on the visual turbidity, the  MIC of the evaluated molecules has been studied, the evaluation concentration was used single therefore, the exact MIC could not determined and results are represented in less than and more than based on growth of microorganism. To get more exact MIC of the tested molecules need to be evaluated at low concentration. Further testing for all compounds at lower concentrations is required to compare their activity with standard Streptomycin at its MIC to get exact MIC the synthesized compounds.


Previously novel synthesized derivatives are; 2-(phenoxymethyl)-5-phenyl-1, 3, 4-oxadiazole (7a), 4-(5-(phenoxymethyl)-1, 3, 4-oxadiazol-2-yl)aniline  (7b), 3-(5-(phenoxymethyl)-1, 3, 4-oxadiazol-2-yl) aniline (7c), 2-(5-(phenoxymethyl)-1, 3, 4-oxadiazol-2-yl)phenol (7d), 2, 4-dinitro-6-(5-(phenoxymethyl)-1, 3, 4-oxadiazol-2-yl)phenol (7e), 2-(4-(methylthio)benzyl)-5-(phenoxymethyl)-1,3,4-oxadiazole (7f), 2-((2, 4-dichlorophenoxy) methyl)-5-phenyl-1,3,4-oxadiazole (7g), 4-(5-((2, 4-dichlorophenoxy) methyl)-1,3,4-oxadiazol-2-yl)aniline (7h), 3-(5-((2, 4-dichlorophenoxy) methyl)-1,3,4-oxadiazol-2-yl)aniline (7i), 2-(5-((2, 4-dichlorophenoxy) methyl)-1, 3, 4-oxadiazol-2-yl)phenol (7j), 2-(5-((2, 4-dichlorophenoxy) methyl)-1,3,4-oxadiazol-2-yl)-4,6-dinitrophenol (7k), 2-((2,4-dichlorophenoxy) methyl)-5-(4-(methylthio)benzyl)-1,3,4-oxadiazole (7l), (Z)-2-((2, 4-dichlorophenoxy) methyl)-5-styryl-1,3,4-oxadiazole (7m), (S)-4-(2-(5-((2,4-dichlorophenoxy) methyl)-1, 3, 4-oxadiazol-2-yl)propyl)phenol (7n), 2-((4-nitrophenoxy) methyl)-5-phenyl-1, 3, 4-oxadiazole (7o), 4-(5-((4-nitrophenoxy)methyl)-1,3,4-oxadiazol-2-yl)aniline (7p), 3-(5-((4-nitrophenoxy)methyl)-1,3,4-oxadiazol-2-yl)aniline (7q), 2-(5-((4-nitrophenoxy)methyl)-1,3,4-oxadiazol-2-yl)phenol (7r), 2, 4-dinitro-6-(5-((4-nitrophenoxy)methyl)-1,3,4-oxadiazol-2-yl)phenol (7s), 2-(4-(methylthio) benzyl)-5-((4-nitrophenoxy) methyl)-1,3,4-oxadiazole (7t), (Z)-2-((4-nitrophenoxy)methyl)-5-styryl-1,3,4-oxadiazole (7u) and 5-((2, 4-dichlorophenoxy) methyl)-1,3,4-oxadiazole-2-thiol (7v).
