The present invention relates to a compound represented by the formula:
wherein
Ar is an optionally substituted ring;
A is a spacer having a main chain of 1 to 4 atoms;
B is a bond, a C
1-10
alkylene group or an oxygen atom;
R
3
and R
5
are each independently a hydrogen atom or a substituent;
R
4
is an optionally substituted cyclic group or an optionally substituted C
1-10
alkyl group; and
R
1
and R
2
are each independently a hydrogen atom or a substituent, or
R
1
and R
2
or R
1
and B are bonded to form an optionally substituted nitrogen-containing heterocycle, or
R
1
and Ar are bonded to form an optionally substituted nitrogen-containing fused heterocycle, or a salt thereof. The thienopyrimidone compound of the present invention has a superior melanin-concentrating hormone receptor antagonistic action, and is useful as an agent for the prophylaxis or treatment of obesity and the like.
