A compound represented by the formula [1]:
wherein ring A and ring B each represent an optionally substituted benzene ring; ring C represents an optionally further substituted aromatic ring; R
1
represents a lower alkyl group optionally substituted with an optionally substituted hydroxyl group; X
1a
represents a bond or optionally substituted lower alkylene; X
1b
represents a bond or optionally substituted lower alkylene; x
2
represents a bond, —O— or —S—; X
3
represents a bond or an optionally substituted divalent hydrocarbon group; Y represents an optionally esterified or amidated carboxyl group, or a salt thereof. The compound of the formula [I] is safer and has more potent lipid lowering activity such as squalene synthase inhibitory activity (cholesterol lowering activity) and triglyceride lowering activity, and thus it is a compound useful as an agent for preventing or treating hyperlipemia.
一种由公式[1]表示的化合物:其中环A和环B分别表示可选择性取代的苯环;环C表示可选择性进一步取代的芳香环;R1表示可选择性取代的较低的烷基,其中还可选择性地取代有一个或多个羟基基团;X1a表示一个键或可选择性取代的较低的烷基烯;X1b表示一个键或可选择性取代的较低的烷基烯;x2表示一个键,-O-或-S-;X3表示一个键或可选择性取代的双价碳氢基团;Y表示可选择性酯化或酰胺化的羧基,或其盐。公式[I]的化合物更安全,并具有更强的降脂活性,如角鲨烷合酶抑制活性(降低胆固醇活性)和三酰甘油降低活性,因此它是一种有用的化合物,可用作预防或治疗高脂血症的药物。
