CILOSTAMIDE

Description

Cilostamide (68550-75-4) is a selective inhibitor of phosphodiesterase-3 (PDE3). Displays limited selectivity for PDE3A versus PDE3B (IC50 = 27 and 50 nM).1,2 Blocks PKB/Akt signaling pathway downstream via inhibition of Akt-activated PDE3B.3 Cilostamide reverses the effect of leptin on food intake and body weight.4

The Uses of CILOSTAMIDE

Cilostamide (OPC 3689) is a specific phosphodiesterase 3 (PDE3) inhibitor.

What are the applications of Application

Cilostamide (OPC 3689) is a specific phosphodiesterase 3 (PDE3) inhibitor

Definition

ChEBI: N-cyclohexyl-N-methyl-4-[(2-oxo-1H-quinolin-6-yl)oxy]butanamide is a member of quinolines.

Biological Activity

Selective inhibitor of type III phosphodiesterase (PDE3). Displays moderate selectivity for PDE3A isozyme vs. PDE3B (IC 50 values are 0.027 and 0.050 μ M for PDE3A and PDE3B respectively). Inhibits ADP-induced platelet aggregation (IC 50 = 16.8 μ M); anti-thrombotic. Also available as part of the Phosphodiesterase Inhibitor Tocriset™ .

Biochem/physiol Actions

Selective inhibitor of PDE3 (cGMP-inhibited phosphodiesterase); IC50 = 70 ± 9 nM. This inhibitory effect increases intracellular cAMP and inhibits platelet aggregation.
