Description
Icariin is a flavonol glycoside and a PDE5 inhibitor (IC50 = 5.9 μM) with 67-fold selectivity for PDE5 over PDE4. It exhibits antioxidant and anticancer activity. At a concentration of 1 x 107 mol/L, Icariin induces differentiation of cardiomyocytes and upregulates the expression of cardiac genes. At 20 μg/ml, Icariin increases the proliferation and differentiation of cultured human osteoblasts. Icariin affects the aging mechanism from different aspects, can delay the aging process and prevent the occurrence of senile diseases.
