Disclosed are compounds represented by formula (I) which have triglyceride biosynthesis inhibitory activity in the liver and inhibitory activity against the secretion of apolipoprotein B-containing lipoprotein from the liver and particularly have excellent inhibitory activity against the secretion of apolipoprotein B-containing lipoprotein, are free from side effect of accumulation of lipids in the liver, and are useful for the treatment and prevention of hyperlipidemia and arteriosclerotic diseases. In formula (I), R<1 >and R<2 >represent alkyl, alkoxy, cycloalkyl, phenyl, alkenyl, alkynyl, or a five- or six-membered saturated or unsaturated heterocyclic ring, or R<1 >and R<2>, together with a nitrogen atom to which R<1 >and R<2 >are attached, may form a ring; R<3 >and R<4 >represent a hydrogen atom, alkyl, a halogen atom, hydroxyl, nitrile, alkoxycarbonyl, alkoxy, or carboxyl; or R<2 >and R<3 >may be attached to each other to form -(CH2)m-, -N=CH-, -CH=N-, or -(C1-6 alkyl)C=N-; A, D, E, and G each represent a carbon atom, or any one of A, D, E, and G represents a nitrogen atom with the other three each representing a carbon atom; Q represents a nitrogen atom or a carbon atom; Y represents a group represented by formula (II) wherein X represents a hydrogen atom, group -C(=O)N(R<5>)R<6 >or group -C(=O)OR<7>, R<8 >is absent or represents a bond, an oxygen atom, a sulfur atom, -SO2-, -SO-, -CH2-CH2-, or -CH=CH-, and R<9 >and R<10 >represent a hydrogen atom, alkyl, alkoxy, a halogen atom, or hydroxyl; and Z represents -(CH2)n-, -O-(CH2)i-, or -C(=O)NH-(CH2)i-. |
