În prezenta lucrare a fost realizată sinteza1,1-dimetil-3-(3-metil-5-sulfanil-4H-1,2,4-triazol-4-il)tioureei (5) şi a1,1-dimetil-3-[3-metil-5-(metilsulfanil)-4H-1,2,4-triazol-4-il]tioureei (6), ale căror structuri au fost stabilite cu ajutorul spectrelor 1H-RMN şi 13C-RMN. Pe celule de cancer cervical substanţele iodhidrat de 3-metil-5-(metilsulfanil)-4H-1,2,4-triazol-4-amină 2) şi 6 au demonstrat o activitate nesemnificativă. Disulfura de tetrametiltiuram(DTMT) a demonstrat rezultate antibacteriene bune CMI 0,0007 mg/mL,iar substanţele 6 şi 2 au CMI 0,007 mg/mL şi, respectiv, 0,06 mg/mL. Tioureea 6 are proprietăţi antioxidante IC50= 29 μM/L aproximativ egale cu ale troloxului.A fost realizată sinteza N-[4-(3-metil-7H-1,2,4]triazolo[3,4-b][1,3,4]-tiadiazin-6-il)fenil]-2-[1-(piridin--il)etiliden]hidrazincarbotioamidei (11) şi a bazei Schiff [{[3-metil-5-(metilsulfanil)-4H-1,2,4-triazol-4-il]imino}metil]fenol (3). La compusul 3a fost efectuată difracţia cu raze X în monocristal.
