Medicines in the DPP4 inhibitor class include sitagliptin, saxagliptin, linagliptin, and alogliptin. However, research data on the mechanism of action of the active ingredients of WBG on DPP4 are also limited. Therefore, this in silico study aimed to idenfy acve ingredients with strong or potential effects on the DPP4 target for andiabec acvity of WBG.
