Icariin

Icariin is a PDE5 inhibitor. It is the active component of the Chinese medicinal plant E. brevicornum. It can induce differentiation of cardiomyocytes and upregulates the expression of cardiac genes. Icariin increase the proliferation and differentiation of cultured human osteoblasts, which appears to be mediated in part by upregulating bone morphogenetic protein 2 mRNA.
