摘要:
Disclosed are compounds represented by formula (I) and pharmaceutically acceptable salts and solvates thereof. The compounds can inhibit the biosynthesis of triglycerides in the liver and can inhibit the secretion of lipoprotein containing apolipoprotein B from the liver. Therefore, they are useful for the prevention or treatment of hyperlipidemia (particularly hyper-very-low-density-lipoproteinemia) and arteriosclerotic diseases, such as cardiac infarction, or pancreatitis induced by hyperlipidemia. wherein A represents group —CR1R2—(CH2)i— where R1 and R2 each represent a hydrogen atom or alkyl, —CH═CH—, —O—CH2—, or —S(O)j—CH2—; B represents a hydrogen or halogen atom; X represents —CR3R4R5, —NR6R7, —(CH2—CH═C(CH3)—CH2)p—CH2CH═C(CH3)2, alkyl, cycloalkyl, phenyl, cinnamyl, or heteroaromatic ring; Y represents —(CH2)q—, —CH═CH—, —NR8—, an oxygen atom, or a bond; Z represents carbonyl or a bond; K represents alkylene or a bond; L represents —CH═CH— or a bond; and M represents a hydrogen atom, alkyl, cycloalkyl, phenyl, heterocyclic ring, biphenyl, or diphenylmethyl.

摘要:
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), R1 and R2 represent alkyl, alkoxy, cycloalkyl, phenyl, alkenyl, alkynyl, or a five- or six-membered saturated or unsaturated heterocyclic ring, or R1 and R2, together with a nitrogen atom to which R1 and R2 are attached, may form a ring; R3 and R4 represent a hydrogen atom, alkyl, a halogen atom, hydroxyl, nitrile, alkoxycarbonyl, alkoxy, or carboxyl; or R2 and R3 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(R5)R6 or group —C(═O)OR7, R8 is absent or represents a bond, an oxygen atom, a sulfur atom, —SO2—, —SO—, —CH2—CH2—, or —CH═CH—, and R9 and R10 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—.

摘要:
A new metallo-β-lactamase inhibitor which acts as a medicament for inhibiting the inactivation of β-lactam antibiotics and recovering anti-bacterial activities is disclosed. The maleic acid derivatives having the general formula (I) have metallo-β-lactamase inhibiting activities. It is possible to recover the anti-bacterial activities of β-lactam antibiotics against metallo-β-lactamase producing bacteria by combining the compound of the general formula (I) with β-lactam antibiotics.
