A series of new 3,6-disubstituted triazolothiadiazole derivatives 7a~7y containing benzimidazole and arylsulfonyl moities have been synthesized by o-phenylenediamine and chloroacetic acid as starting materials via multistep reactions.The structures of the intermediates 3,4,6 and the target compounds 7 were characterized by 1H NMR,IR spectra and elemental analysis.All synthesized target compounds were screened for their inhibitory activity against cell division cycle 25B phosphatase (Cdc25B) and protein tyrosine phosphatase 1B (PTP1B).The results show that some of them display significant inhibitory activities against Cdc25B and PTP1B.Among them,compound 7d exhibits the highest inhibitory activity against Cdc25B [IC50=(7.72±0.73)μg/mL]and 7u exhibits the highest inhibitory activity against PTP1B[IC50=(3.31±0.57)μg/mL].It is noteworthy that compounds 7b,7d,7l,7t and 7u show higher inhibitory activities against Cdc25B and PTP1B.They can be considered as potential Cdc25B and PTP1B inhibitors,and have great application prospects in the treatment of cancers and diabetes.

Key words: triazolothiadiazole, benzimidazole, arylsulfonyl, synthesis, Cdc25B and PTP1B inhibitors
