Application

Zaprinast has been used to determine its inhibitory effect on the meiosis of oocytes by germinal vesicle breakdown (GVBD) assay and to test the inhibitory effect of it on the retinal cells by immunohistochemistry.

Biochem/physiol Actions

Zaprinast insubstantially inhibits phosphodiesterase 10 and 11 (PDE10 and PDE11). It also exhibits vasodilating effects.
Selective inhibitor of cGMP-specific phosphodiesterases V and VI (PDE5/6) and an agonist at the G protein-coupled receptor 35 (GPR35).

Of the 11 families of mammalian cyclic nucleotide phosphodiesterases (PDEs), 5 contain regulatory domains capable of binding cyclic guanosine 5'-monophosphate (cGMP). The best understood of the GAF-containing PDEs is the family of rod (PDE6R) and cone (PDE6C) photo receptor PDEs.

High-frequency stimulation (HFS) of corticostriatal glutamatergic fibers induces long-term depression (LTD) of excitatory synaptic potentials recorded from striatal spiny neurons. This form of LTD can be mimicked by zaprinast, a selective inhibitor of cGMP phosphodiesterases (PDEs). Biochemical analysis shows that
