Inhibition of protein tyrosine phosphatase 1B (PTP1B) activity has been considered as a promising therapy approach to treat typern2 diabetes. In this work, a novel PTP1B activity inhibitor, named FYGL (Fudan-Yueyang-G. lucidum), was screened from thernfruiting bodies of Ganoderma lucidum, and showed an effi cient PTP1B inhibitory potency with IC50=5.12±0.05μg/mL. Th e type 2rndiabetic animals treated orally by FYGL showed an obvious decrease in the plasma glucose level, and comparable with those treatedrnby metformin, a clinic drug. Th e toxicity of FYGL is very low. FYGL is a water soluble hyperbranched proteoglycan with molecularrnweight (Mη) of 105. In addition, it was also found that FYGL could protect against the renal functional and morphologic injuries byrnincreasing the activities of antioxidants and inhibiting the accumulation of oxidation. Th e results indicate that FYGL may serve as arndrug candidate or a health-care food for the diabetic therapy and renal functional protection.
