Yadav 1 Daroga Singh 1 Department of Chemistry, T.D. College, Jaunpur (U.P.) INDIA <p>Condensation of 4-bromo-3-aryl pyrazol-5(4H)-one (1) with 3-substitued-4-amino-5-mercapto-1,2,4-triazoles (2) in ethanol in the presence of pyridine afforded 3,8-disubstitued-5H-s-triazolo (3,4-b) pyrazolo (5,4-e) -1,3,4- thiadiazines (3). The antifungal and antibacterial activity of synthesized compounds have also been evaluated.   </p> https://journalofchemistry.org/paper/808/ ANTIMICROBIAL ACTIVITY Synthesis
