Seven pimarane diterpenes (-) were isolated fromBenth. by assay-guided isolation. All of the isolates possessed a 2-deoxy-2-((7-nitro-2,1,3-benzoxadiazol-4-yl)amino)-d-glucose uptake effect in 3T3-L1 adipocytes at concentrations of 5 and 10μM. Most of them showed potent inhibition against protein tyrosine phosphatase 1B with ICvalues ranging from 0.33 to 9.84μM. In the kinetic study, all inhibition types were exposed for the examined potencies, including mixed-competitive (), non-competitives (and), competitive (), and uncompetitive (). The results suggested thatand its pimarane diterpenes might exert the hypoglycemic effect via the insulin signaling pathway targeting inhibition of protein tyrosine phosphatase 1B (PTP1B) activity.
