Zoniporide (CP-597396) hydrochloride 是 1 型鈉氫交換劑 (NHE-1) 的有效和選擇性抑制劑。Zoniporide hydrochloride 抑制人 NHE-1 (IC50=14 nM),與其他 NHE 亞型相比具有大于 150 倍的選擇性,并有效抑制離體 NHE-1 依賴性的人血小板溶脹 (IC50=59 nM)。
Zoniporide (0.25-4 mg/kg; i.v.; every hour for 2 hours) elicits a dose-dependent reduction in infarct size (ED
50
=0.45 mg/kg/h) in open chest anesthetized rabbits.
Zoniporide exhibits moderate plasma protein binding, has a t
1/2
of 1.5 hours in monkeys, and has one major active metabolite.
Zoniporide treatment shows the AUC
0-∞
and t
1/2
are 0.07 μg h/mL and 0.5 hours, respectively.
