The present invention provides a novel diazepine compound that blocks the IKur current or the Kv1.5 channel potently and more selectively than other K+ channels. The present invention relates to a diazepine compound represented by General Formula (1)
or a salt thereof,
wherein R1, R2, R3, and R4 are each independently hydrogen, lower alkyl, cyclo lower alkyl or lower alkoxy lower alkyl;
R2 and R3 may be linked to form lower alkylene;
A1 is lower alkylene optionally substituted with one or more substituents selected from the group consisting of hydroxyl and oxo;
Y1 and Y2 are each independently —N═ or —CH═;
and
R5 is group represented by
wherein R6 and R7 are each independently hydrogen or organic group;
R6 and R7 may be linked to form a ring together with the neighboring group —XA—N—XB—;
XA and XB are each independently a bond, lower alkylene, etc.
本发明提供了一种新型的二氮杂环化合物,它能够比其他K+通道更强烈和更选择性地阻断IKur电流或Kv1.5通道。本发明涉及一种由通式(1)表示的二氮杂环化合物或其盐,其中R1、R2、R3和R4各自独立地为氢、较低的烷基、环较低的烷基或较低的烷氧基烷基;R2和R3可以连接形成较低的烷基;A1是较低的烷基,可选地被一个或多个取代基所取代,所述取代基被选择自羟基和氧代基的群组成;Y1和Y2各自独立地为—N═或—CH═;以及R5是由下式表示的基团:其中R6和R7各自独立地为氢或有机基团;R6和R7可以连接形成一个环,与相邻的基团—XA—N—XB—一起;XA和XB各自独立地为一个键、较低的烷基等。
