Synthesis and biological activities of novel 1,2,4-triazole thiones and bis(1,2,4-triazole thiones) containing phenylpyrazole and piperazine moieties

A series of novel 1,2,4-triazole thione and bis(1,2,4-triazole thione) derivatives containing phenylpyrazole and substituted piperazine moieties have been conveniently synthesized via Mannich reaction using various 1,2,4-triazole thiols, substituted piperazines, and formaldehyde at room temperature in short time. Their structures were confirmed by IR, 1H NMR, 13C NMR and elemental analysis. The preliminary bioassays for 27 new title compounds have shown that some of them possess certain herbicidal activities against Echinochloa crusgalli at 100 μg/mL concentration. Some of the compounds exhibited significant in vitro fungicidal activities, especially against Cercospora arachidicola and Rhizoctonia cerealis at the concentration of 50 μg/mL, and were comparable with that of control Triadimefon. Meanwhile, IXp held the control efficacy of 60% against Puccinia sorghi Schw. at 200 μg/mL concentration in the in vivo test. The SAR analysis has indicated that compounds with two CF3 groups both on triazole and pyrazole rings are more effective than compounds with one CF3 group or two CH3 groups according to their fungicidal activity data. On the whole, compounds VIIIg, IXi, IXo and IXp could be used as novel lead structures for the design and discovery of new fungicides.
