The present invention provides a novel dihydroorotic acid dehydrogenase inhibitor which is applicable to various diseases. When used as an active ingredient, a compound represented by formula (I):
(wherein
X represents a halogen atom,
R
1
represents a hydrogen atom,
R
2
represents an alkyl group containing 1 to 7 carbon atoms,
R
3
represents —CHO, and
R
4
represents —CH
2
—CH═C(CH
3
)—R
0
(wherein R
0
represents an alkyl group containing 1 to 12 carbon atoms which may have a substituent on the terminal carbon and/or on a non-terminal carbon, etc.)),
an optical isomer thereof or a pharmaceutically acceptable salt thereof has a high inhibitory effect on dihydroorotic acid dehydrogenase and can be used as an immunosuppressive agent, a therapeutic agent for rheumatism, an anticancer agent, a therapeutic agent for graft rejection, an antiviral agent, an anti-
H. pylori
agent, a therapeutic agent for diabetes or the like.
