title: Synthesis and antimicrobial activity of N-[(alpha-methyl)benzylidene]-(3-substituted-1,2,4-triazol-5-yl-thio) acetohydrazides.
abstract: In this study 18 new hydrazones have been synthesized by reacting ortho- or para-substituted acetophenones with (3-substituted-1,2,4-triazol-5-yl-thio)acetohydrazide in ethanol. The prepared compounds were tested for antimicrobial activity. The prepared compounds exhibited only poor activity against Gram (+) and Gram (-) bacteria with the minimal inhibitory concentration (MIC) > or = 400 micrograms/ml. Moderate activity was observed against Candida species with MIC in the range 100-400 micrograms/ml.
