Zaprinast (M&B 22948) is a selective inhibitor of cGMP-selective Phosphodiesterase (PDE5). Zaprinast causes a significant increase in cGMP levels in myocytes. Zaprinast is a G protein-coupled receptor 35 (GPR35) agonist which activates rat GPR35 strongly and activates human GPR35 moderately. Zaprinast reduces vessel remodeling through antiproliferative and proapoptotic effects[1][2][3].
IC50 & Target:PDE[1], GPR35[2]
In Vitro:Zaprinast (0.1, 0.3, 1, 3, 10, 30 μM) induces intracellular calcium mobilization in the transfectant coexpressing FLAG-hGPR35 and the four exogenous Gα proteins in a concentration-dependent manner in HEK293 cells[2].
Zaprinast (100 μM; 5 min) can promote phosphorylation of five distinct amino acids in the C-terminal tail of human GPR35a in HEK293T cells[4].
In Vivo:Zaprinast (3 and 10 mg/kg; i.p.) enhances spatial memory in elevated plus maze (EPM) and diminishes exploratory activity in the Hughes box test[5].
