Pterosin B

• Description :

  Pterosin B is an orally active indanone. Pterosin B can be obtained from Pteridium aquilinum. Pterosin B is a Sik3 signaling inhibitor. Pterosin B inhibits Klf5 expression and reduces β-amyloid deposition. Pterosin B prevents chondrocyte hypertrophy and osteoarthritis in mice. Pterosin B inhibits cardiomyocyte hypertrophy, improves cognitive impairment, and lowers blood glucose. Pterosin B can be used in research on arthritis, Alzheimer's disease, pathological cardiac hypertrophy and diabetes[1][2][3][4][5].
