Identification of Active Component of Hachimi-jio-gan Ameliorating Diabetic Nephropathy

摘要

Conventional medicine-based Chinese herbal prescriptions,have fascinated much attention due to their extensive and unique diversity of biological effects without toxicity and/or adverse effects.Treatment with Hachimi-jio-gan(Ba-Wei-Di-Huang-Wan in Chinese)improved the dysregulated levels of hyperglycemic condition-related oxidative stress generation,advanced glycation endproduct generation,and renal function parameters.These results indicate that Hachimi-jio-gan is a prospective therapeutic agent against the pathogenesis of diabetic nephropathy.Cornel iridoid glycosides and polyphenol are the active compounds of Corni Fructus,the active component of Hachimi-jio-gan,against kidney damage caused by diabetes.Additionally,major components of the Corni Fructus,morroniside and 7-O-Galloyl-D-sedoheptulose(GS)are considered to be important contributors to prevent and/or delay the onset of kidney damage caused by diabetes.Chief of all,GS is expected to be developed as a novel therapeutic drug for the diabetes-accelerated kidney damage.
