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.
