Synthesis and Tuberculostatic Activity of Some 2-Piperazinmethylene Derivatives 1,2,4-Triazole-3-Thiones

Abstract The Mannich reaction's products of 1,2,4-triazole-3-thiones, substituted in position 4 (with ethyl, allyl, phenyl, Ph-4-Br) or 5 (with phenyl, Ph-4-OH, Ph-3,4,5-(OMe)3, 2-phenyl) were obtained. Their amino-components were 1-phenylpiperazine, 1-(4-fluorophenyl)-piperazine, 1-benzylpiperazine, 1-(2-pyridyl)-piperazine and 1-piperonyl-piperazine. Tuberculostatic activity of the compounds obtained was tested and their MIC values within 25–100 mcg/mL.
