常见问题列表
生物活性
Sematilide (CK-1752) 是一种选择性的 IKr 通道阻滞剂。Sematilide 抑制延迟整流钾通道 (K+ current)，IC50 为 25 μM，这种作用存在浓度依赖性。Sematilide 是一种 III 类抗心律不齐剂。靶点
IC50: 25 μM (K + current)
体外研究
Application of 10, 30, 100 and 300 μM Sematilide causes a concentration-dependent inhibition of the delayed rectifier K + current (IC 50 =25 μM).
体内研究
Sematilide (0.3-1.0 mg/kg, intravenously i.v.) is effective in a canine model of arrhythmia.
