摘要:
Biphenyl derivative of the formula: wherein R¹ is hydrogen atom or a lower alkoxycarbonyl group and R² is a lower alkoxycarbonyl group, or R¹ and R² are combined together to form a group of the formula: each of R³ and R⁴ is a lower alkoxy group; and Ring A is a substituted or unsubstituted sulfur-containing or nitrogen-containing heterocyclic ring, and a pharmaceutically acceptable salt thereof are disclosed. Said biphenyl derivative (I) and its salt have excellent hypolipidemic activity and are useful for treatment or prophylaxis of hyperlipidemia and/or arteriosclerosis.

Naphthalene derivatives of the formula: wherein R 1 is hydrogen atom or a lower alkoxycarbonyl and R 2 is a lower alkoxycarbonyl, or R' and R 2 are combined together to form a group of the formula: each of R 3 and R 4 is a lower alkoxy, or one of R 3 and R 4 is hydrogen atom and the other is a lower alkoxy, and Ring A is a substituted or unsubstituted benzene ring, and a pharmaceutically acceptable salt thereof are disclosed. Said naphthalene derivative (I) and its salt have excellent hypolipidemic activity and are useful for treatment or prophylaxis of hyperlipidemia and/or arteriosclerosis. Disclosed are also a process for the production of compounds of formula (I), the use of said compounds and the production of medicaments and pharmaceutical compositions containing compounds of formula (1) as active ingredient.
摘要:
The invention relates to furyloxazolylacetic acid derivatives of the formula: wherein R' is alkyl of one to 6 carbon atoms, cycloalkyl of 5 to 6 carbon atoms, phenyl or a substituted phenyl (said substituted phenyl being phenyl group substituted with one or two radicals selected from alkyl of one to 2 carbon atoms, alkoxy of one to 2 carbon atoms and halogen), and R 2 is hydrogen or alkyl of one to 12 carbon atoms. The compound (I) is useful as a hypolipidemic agent. The invention comprises also processes for the produc- ti on of said furyloxazolylacetic acid derivatives and pharmaceutical compositions containing same.
摘要:
A chromene or thiochromene derivative of the formula: wherein A is oxygen or sulfur atom, R¹ is a halogenophenyl, R² and R³ are the same or different and are each a lower alkyl or R² and R³ are combined together to form -(CH₂) n - in which n is an integer of 4 to 6, or a pharmaceutically acceptable ester, amide, lactone or salt thereof, which has excellent HMG-CoA reductase inhibitory activity and is useful for prophylaxis and treatment of hyperlipidemic diseases, a process for preparing said compound and an intermediate compound used for preparing said compound. Further, a pharmaceutical composition containing the above mentioned chromene or thiochromene derivatives is disclosed.
