3-piperidyl-4-oxoquinazoline derivatives are provided, which is represented by the formula (I):
wherein R represents an amino group or a cyclic amino group such as dibenzoazepine, each of which is substituted with a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group, or the like, n is an integer of 1 to 3, R3 and R4 independently represents a hydrogen atom, a lower alkyl group, or the like, or a pharmaceutically acceptable salt thereof. Compounds (I) of the present invention have excellent MTP-inhibitory activity. Thus, these compounds not only inhibit formation of LDL that is a cause of arteriosclerotic diseases but also regulate TG, cholesterol, and lipoproteins such as LDL in the blood and regulate cellular lipids through regulation of MTP activity. They can also be used as a new type of preventive or therapeutic agents for hyperlipemia or arteriosclerotic diseases. Furthermore, they can be used as therapeutic or preventive agents for pancreatitis, obesity, hypercholesterolemia, and hypertriglyceridemia.
本发明提供了3-
哌啶基-4-氧
喹唑啉衍
生物,其由式(I)表示:其中R代表
氨基或环
氨基,例如二苯并氮杂环,每个都被取代或未取代的芳基基团,取代或未取代的杂环基团或类似物所取代,n是1到3的整数,R3和R4独立地表示氢原子,低碳基或类似物,或其药学上可接受的盐。本发明化合物(I)具有出色的
MTP抑制活性。因此,这些化合物不仅抑制了导致动脉硬化疾病的LDL的形成,还通过调节
MTP活性来调节血液中的TG,
胆固醇和脂蛋白如LDL,并通过调节细胞脂质来使用作为新型的高脂血症或动脉硬化疾病的预防或治疗药物。此外,它们还可以用作胰腺炎,肥胖症,高
胆固醇血症和高三酰
甘油血症的治疗或预防剂。
