Icariin is a flavonol glycoside. Icariin inhibits PDE5 and PDE4 activities with IC50 of 432 nM and 73.50 μM, respectively. Icariin also is a PPARα activator[1]. It has exert anti-oxidative, anti-neuroinflammatory, and anti-apoptotic effects[2].
In vitro experiment it shown that treatment of 10 or 20 μM induced 13.1 ± 2.1% and 18.2 ± 1.6% apoptosis in MDA‐MB‐453 cells respectively in comparison with control group. 4T1 cells were treated with 20 μM icariin triggered cell apoptosis[3].
In vivo, rats were injected in 50 mg/kg Icariin significantly reduced paw swelling in carrageenan-injected animals and ameliorated carrageenan-induced paw histopathological alterations. Icariin obviously increased paw enzymatic and non-enzymatic antioxidants and decreased paw lipid peroxidation. Icariin decreased paw levels of inflammatory cytokines and NF-kB[4].
In vivo, rats were administrated with 25 mg/kg and 50 mg/kg icariin improved depression symptoms via regulation of the PI3K-AKT pathway, boosted the expression of the regulatory methylene p85 and catalytic methylene p110 of PI3K, increased the relative expression of p-AKT, and encouraged the expression of the anti-apoptosis factor Bcl-2, thus elevating the ratio of Bcl-2/Bax[5]. In vivo, C57BL/6 J mice were administrated with 50 mg/kg/d icariin effectively attenuated alcohol consumption-induced atrial structural and electrical remodeling[6].
