Abstract:

Sixteen novel double-heterocyclic modified amide sulfide derivatives containing 1,2,4-triazole and 1,3,4-thiadiazole were designed and synthesized, and their structures were characterized. The inhibitory activities of synthesized molecules against cell division cycle 25B(Cdc25B) of protein tyrosine phosphatase 1B(PTP1B) were evaluated. The results show that all target molecules exhibit good inhibitory activity against PTP1B. Compounds 8-C-d and 8-D-c have the optimal inhibition. Their half maximal inhibitory concentration(IC50) values are (1.19±0.22) mg/L and (1.08±0.09) mg/L, respectively, which are lower than that of positive reference oleanolic acid(IC50=(1.27±0.19) mg/L). They are expected to be anti-diabetic drug leading compounds. The target molecules also exhibit good inhibitory activities against Cdc25B. The IC50 values of compounds 8-A-d, 8-C-d and 8-D-c are higher than that of positive reference Na3VO4(IC50=(1.25±0.14) mg/L), which are expected to be anticancer drug leading compounds.
