Seven pimarane diterpenes (1-7) were isolated from Orthosiphon stamineus Benth. 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 10 μM. Most of
Leptin resistance is a common feature of obesity and is accompanied by hyperleptinemia. Although leptin sensitizers improve leptin resistance, they also decrease plasma leptin levels that attenuate the leptin-associated antiobesity effect. We hypothesized that the combinational treatment of leptin
