Zoniporide (CP-597396) is a potent and selective NHE-1 inhibitor with cardioprotective activity. Zoniporide inhibits 22Na+ uptake by human NHE-1-expressing fibroblasts in a concentration-dependent manner (IC50=14 nM). Zoniporide inhibits platelet swelling in vitro with an IC50 of 0.059 μM. Zoniporide can be used in the study of cardiovascular disease.
