The present invention provides a novel benzodiazepine compound that blocks the IKur current or the Kv1.5 channel potently and more selectively than other K+ channels. The benzodiazepine compound of the invention is represented by General Formula (1)
wherein R1, R2, R3, and R4 are each independently hydrogen or lower alkyl; R2 and R3 may be linked to form lower alkylene;
Al is lower alkylene optionally substituted with one or more hydroxy; and
R5 is group represented by
wherein R6 and R7 are each independently hydrogen or organic group;
XA and XB are each independently bond, lower alkylene, etc.
本发明提供了一种新型苯二氮平化合物,能够有效地选择性地阻断IKur电流或Kv1.5通道,比其他K+通道更具选择性。本发明的苯二氮平化合物由通式(1)表示,其中R1、R2、R3和R4各自独立地代表氢或较低的烷基;R2和R3可以连接形成较低的烷基;Al代表较低的烷基,可选地取代一个或多个羟基;R5代表下列基团:其中R6和R7各自独立地代表氢或有机基团;XA和XB各自独立地代表键、较低的烷基等。
