Vinpocetine (Standard) is the analytical standard of Vinpocetine. This product is intended for research and analytical applications. Vinpocetine (Ethyl apovincaminate) is a derivative of the alkaloid Vincamine that blocks voltage-gated Na+ channels. The IC50 value of Vinpocetine on direct IKK inhibition in the cell-free system is 17.17 µM. Vinpocetine is a phosphodiesterase (PDE) inhibitor and inhibits NF-kappaB-dependent inflammatory responses by directly targeting IkappaB kinase complex (IKK), and has been widely used for the treatment of cerebrovascular disorders[1][2][3].
