and safe therapeutic target for the treatment of atrial fibrillation (AF), the most common arrhythmia that threatens human. Herein, by modifying the hit compound 7k from an in-house database, 48 derivatives were synthesized for the assay of their Kv1.5 inhibitory effects by whole cell patch clamp technique. Six compounds which showed better potency than the positive compound dronedarone were selected
Kv1.5钾通道是一种治疗房颤(AF)的有效且安全的治疗靶标,它是威胁人类的最常见心律不齐。本文中,通过从内部数据库中修改命中化合物7k,合成了48种衍生物,以通过全细胞膜片钳技术测定其Kv1.5抑制作用。选择了六种显示出比阳性化合物决奈达隆更好的效价的化合物用于其类药物性质的下一个评估。化合物8显示出平衡的溶解度和渗透性。它还显示出可接受的药效学特征,急性毒性非常低。考虑到所有这些数据,化合物8 可以作为开发用于治疗AF的新型治疗剂的有希望的先导。
