Abstract
In search of the better antibacterial agents, a series of novel new 2-(((5-aryl-1,2,4-oxadiazol-3-yl)methyl)sulfonyl)benzo[d]oxazole derivatives were synthesized using 2-(benzo[d]oxazol-2-ylsulfonyl)acetonitrile and readily available aromatic carboxylic acids. The newly synthesized derivatives were evaluated for their in vitro antibacterial activity against G+ve strains. 2-(((5-(4-fluorophenyl)-1,2,4-oxadiazol-3-yl)methyl)sulfonyl)benzo[d]oxazole showed significant activity against B. subtilis, which is two times higher than that of ciprofloxacin. Anti-biofilm activity results reveled that, 2-(((5-(4-fluorophenyl)-1,2,4-oxadiazol-3-yl)methyl)sulfonyl)benzo[d]oxazole and 4-(3-((benzo[d]oxazol-2-ylsulfonyl)methyl)-1,2,4-oxadiazol-5-yl)benzonitrile shows effective inhibitors of biofilm growth. Molecular docking and ADME studies have also been conducted to complement the experimental results.
