Proteintyrosinephosphatase1B (PTP1B) is a negative regulator in the process of insulin signaling and a promising drug target for diabetes and obesity. Derivatives of oleanolic acid were synthesized and evaluated as PTP1B inhibitors. Several derivatives exhibited moderate to good inhibitory activities against PTP1B, with 25f displaying the most promising inhibition (IC50 = 3.12 μM). Structure−activity

α-Glucosidase is a promising target for the treatment of obesity and diabetes mellitus. A series of oleanolicacid derivative–chalcone conjugates were designed and synthesized as α-glucosidaseinhibitors. Their structures were determined by spectroscopic analysis and their α-glucosidase inhibitory activities were investigated in vitro. Most conjugates exhibited moderate inhibitory activity against
