产品描述: Ibutilide (U70226E free base) 是一种延长动作电位的抗心律失常剂,作用于 AT-1 细胞,可有效阻断快激活延迟整流钾电流 (IKr)。
体外研究: Ibutilide is a potent IKr blocker with an EC50 value of 20 nM at +20 mV in atrial tumor myocytes (AT-1) cells.
Ibutilide blocks IKr in cells expressing HERG+MDR1*1 to the same extent as cells expressing HERG alone (IC50: 22.5 nM vs 27.4 nM). However, cells expressing MDR1*7 show a marked resistance to Ibutilide (IC50: 105.3 nM vs 27.4 nM).
体内研究: Ibutilide prolongs cardiac repolarization in vitro and in vivo.
Ibutilide infusions (administered cumulatively in three doses, 0.01, 0.02 and 0.05 mg/kg i.v., each as a 10-min infusion) results in both polymorphic and monomorphic non-sustained ventricular tachycardia.
