Zoniporide hydrochloride  (Synonyms: CP-597396 hydrochloride)

Zoniporide (CP-597396) hydrochloride is a potent and selective inhibitor of sodium-hydrogen exchanger type 1 (NHE-1). Zoniporide hydrochloride inhibits human NHE-1 (IC₅₀=14 nM), and has >150-fold selectivity versus other NHE isoforms. Zoniporide hydrochloride potently inhibits ex vivo NHE-1-dependent swelling of human platelets (IC₅₀=59 nM)^[1][2].

IC50: 14 nM (NHE-1)^[1]

Zoniporide (0.25-4 mg/kg; i.v.; every hour for 2 hours) elicits a dose-dependent reduction in infarct size (ED₅₀=0.45 mg/kg/h) in open chest anesthetized rabbits^[1].
Zoniporide exhibits moderate plasma protein binding, has a t_1/2 of 1.5 hours in monkeys, and has one major active metabolite^[1].
Zoniporide treatment shows the AUC_0-∞ and t_1/2 are 0.07 μg h/mL and 0.5 hours, respectively^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
