Synthesis and antimicrobial activity of some substituted 1, 3, 4-oxadiazole and other heterocycles derived from 4, 5-dimethoxy-2-nitrophenyl-thioacetic acid hydrazide

ABSTRACT

Anumber of substituted oxadiazoles, benzothiazinones and other heterocycles were synthesized from 4, 5-dimethoxy-2-nitrophenylthioacetic acid hydrazide. The structures of the prepared compounds were confirmed via their elemental analysis and the usual physical measurements. The prepared compounds have been screened for their antimicrobial activities against examples from gram positive, gram negative bacteria and fungi. Two of the tested compounds showed high activity comparable with the reference Levofloxacin while the others showed moderate to low activity
