Ethnopharmacological relevanceExtracts of Andrographis paniculata Nees are used for various ethnomedical conditions including hyperglycemia and hypertension complications.Aim of the studyThe purpose of this study is to evaluate the anti-diabetic nephropathy effect of diterpene lactones andrographolide (AP1) and 14-deoxy-11,12-didehydroandrographolide (AP2) from Andrographis paniculata.Materials and methodsMES-13, a SV40-transformed murine glomerular mesangial cell line, was cultured in high concentration of glucose to induce diabetic nephropathy phenotypes, which include secretion of extracellular matrix protein fibronectin, cytokine TGF-β, states of oxidative stress, and apoptosis marker caspase-3.ResultsOur data suggest that addition of compounds AP1 or AP2 reduces the phenotypes indicating diabetic nephropathy in MES-13 cells. The compound AP2 showed potent activity than AP1 in the reduction of apoptosis marker caspase-3, fibrosis marker TGF-β, and PAI-1. Furthermore, AP1 and AP2 do not have antioxidant ability in acellular environment; however, addition of AP1 and AP2 reduced intracellular oxidative states in high glucose cultured MES-13 cells.ConclusionThis is the first report on anti-diabetic nephropathy effect of AP1 and AP2 in part due to the regulation of intracellular signaling transduction, not mere clearance of reactive oxygen species. Thus, this study may be useful for drug development or food supplement for diabetes and nephropathy from Andrographis paniculata.
This study showed that andrographolide (AP1) and 14-deoxy-11,12- didehydroandrographolide (AP2), which were isolated from Andrographis paniculata reduced the induced ECM fibronectin, cytokine TGF-β, plasminogen activator inhibitor-1, and apoptosis marker caspase-3 in hyperglycemic MES-13 cells.Figure optionsDownload as PowerPoint slide
