摘要:
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.
摘要:
Provided is a new antiparasitic agent for medical use, veterinary use, agrochemical use, and use in fish, said antiparasitic agent having an effect on both helminths and protozoa. The antiparasitic agent uses at least one siccanin produced by Helminthosproium siccans which is a filamentous fungus, a synthetic siccanin, or a modified derivative thereof.
