The present invention provides a novel diazepine compound that blocks the I
Kur
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 R
1
, R
2
, R
3
, and R
4
are each independently hydrogen, lower alkyl, cyclo lower alkyl or lower alkoxy lower alkyl;
R
2
and R
3
may be linked to form lower alkylene;
A
1
is lower alkylene optionally substituted with one or more substituents selected from the group consisting of hydroxyl and oxo;
Y
1
and Y
2
are each independently —N═ or —CH═;
and
R
5
is group represented by
wherein R
6
and R
7
are each independently hydrogen or organic group;
R
6
and R
7
may be linked to form a ring together with the neighboring group —X
A
—N—X
B
—;
X
A
and X
B
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,它可以有效地阻断IKur电流或Kv1.5通道,并比其他K+通道更具选择性。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各自独立地表示氢、低碳基、环状低碳基或低烷氧基低碳基;R2和R3可以连接形成低碳烷基;A1是低碳烷基,可选地取代一个或多个羟基和氧代基;Y1和Y2各自独立地表示—N═或—CH═;R5是由下式表示的基:其中R6和R7各自独立地表示氢或有机基团;R6和R7可以与相邻的基团—XA—N—XB—一起形成环;XA和XB各自独立地表示键、低碳烷基等。
