Mechanism of Action

Targets/IC₅₀/Ki	PDE3 0.2 μM
In vitro	Cilostazol (OPC-13013) is a 2-oxo-quinoline derivative with antithrombotic, vasodilator, antimitogenic and cardiotonic properties. The vasodilatory and antiplatelet actions of this compound are due mainly to the inhibition of phosphodiesterase 3 (PDE3) and subsequent elevation of intracellular cAMP levels. It inhibits platelet aggregation. This compound also possesses the ability to inhibit adenosine uptake. Elevation of interstitial adenosine by this chemical in the heart is shown to reduce increases in cAMP caused by the PDE3-inhibitory action of cilostazol, thus attenuating the cardiotonic effects. It is reported to inhibit smooth muscle cell proliferation. This agent relaxes vascular smooth muscle and causes vasodilatation. It inhibits the cytokine-induced expression of monocyte chemoattractant protein-1 (MCP-1). This compound reduced plasma triglycerides and raised plasma HDL-cholesterol .
