Activation of AKT signaling via small molecule natural compound prevents against osteoblast apoptosis and osteonecrosis of the femoral head.

Vinpocetine (Vinp), a natural compound extracted from the leaves of Phyllostachys pubescens with apoptosis modulatory properties in variety of disorders. In the present study, we investigated the possible mechanism of Vinp in alleviating of the progress of osteonecrosis of the femoral head (ONFH) both in vitro and in vivo experiments. The results showed that treatment with Vinp suppressed the dexamethasone (Dex) induced over-regulation of ROS level and apoptotic factors. Mechanistically, the Vinp activated Akt signaling pathway in osteoblast. Moreover, Vinp exerted a protective role in animal ONFH model. To summarize, this work illustrated Vinp possessed a new potential therapeutic drug in ONFH. AJTR
