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.
本发明提供了一种新型的二氢乳酸酸脱氢酶抑制剂,可用于多种疾病。当用作活性成分时,式(I)所表示的化合物:(其中X表示卤素原子,R1表示氢原子,R2表示含有1至7个碳原子的烷基,R3表示—CHO,R4表示—CH2—CH═C(CH3)—R0(其中R0表示含有1至12个碳原子的烷基,其末端碳和/或非末端碳上可能有取代基等),其光学异构体或其药学上可接受的盐对二氢乳酸酸脱氢酶具有高抑制作用,可用作免疫抑制剂、治疗风湿病的药物、抗癌药物、移植排斥治疗药物、抗病毒药物、抗H. pylori药物、糖尿病治疗药物或类似药物。
