摘要

A simple condensation afforded some new 3-thioxo-1,2,4-triazin-5-one derivatives (4, 6 and 8). Utilizing a facile condensation of (E)-4-(4’-bromo styryl)-2-oxo-3-buteneoic acid with thiosemicarbazide, dithioic formic acid hydrazide, and thiocarbahydrazide in different conditions. Structures of these compounds were confirmed by elemental and spectral analysis. The preliminary biocidal activity of these products were evaluated against some microbial and compared to Mycostatine and piperacillin as antibiotics were most of derivatives exhibited good activity.
