Human A3 adenosine receptor hA3AR has been implicated in gastrointestinal cancer, where its cellular expression has been found increased, thus suggesting its potential as a molecular target for novel anticancer compounds. Observation

A series of novel dimethylpyrazole and piperazine-containing (bis)1,2,4-triazole derivatives have been conveniently synthesized via Mannich reaction in good yields. Their structures were identified by IR,1H NMR,13C NMR, and elemental analysis. The preliminary bioassays showed that among 14 new compounds, the trifluoromethyl-containing compounds exhibited superior activity than the methyl-containing ones; some of the compounds displayed significant in vitro and in vivo fungicidal activity against several plant fungi and were comparable with the control Triadimefon; several compounds exhibited certain herbicidal activity against Brassica campestris; several compounds possessed favorable KARI inhibitory activity, especially 8D could be a promising KARI inhibitor for further study. The research results will provide useful information for the design and discovery of new agrochemicals with novel heterocyclic Mannich base structures containing piperazine moiety.

A series of novel acetylated piperazine-containing N-glucosides and bis(N-glucoside) 8a-i were synthesized by the nucleophilic addition of acetylated glucopyranosyl isothiocyanate with various substituted piperazines in THF with high yields. Their novel deacetylated products 9a-i were also synthesized after Me-ONa/MeOH treatment. The preliminary bioassays for 18 novel title compounds showed that several compounds have significant fungicidal activity against Fusarium omysporum, Cercospora arachidicola and Phytophthora capsici at 50 μg/mL.
