A bicyclic cinnamide compound represented by the general formula (I):
wherein ---- represents a single bond or a double bond; Ar1 represents a phenyl group or pyridinyl group optionally substituted by one to three substituents; R1 and R2 each represents a C1-6 alkyl group, a hydroxyl group, etc.; Z1 represents an optionally substituted methylene group or vinylene group, an oxygen atom, or an imino group optionally substituted by a Cl-6 alkyl group or a Cl-6 acyl group; and p, q, and r each is an integer of 0 to 2. It functions to reduce Aβ40 and Aβ42. It is hence useful especially as a prevention or remedy for neurodegenerative diseases of which Aβ is causative, such as Alzheimer's disease and Down's syndrome.
由通式(I)代表的双环肉桂化合物:
其中 ---- 代表单键或双键;Ar1 代表任选被一至三个取代基取代的苯基或吡啶基;R1 和 R2 分别代表 C1-6 烷基、羟基等;Z1 代表任选被取代的亚甲基或亚乙烯基、氧原子或任选被 Cl-6 烷基或 Cl-6 丙烯酸基取代的亚氨基;p、q 和 r 分别为 0 至 2 的整数。 它具有降低 Aβ40 和 Aβ42 的功能。因此,它特别适用于预防或治疗 Aβ 导致的神经退行性疾病,如阿尔茨海默氏症和唐氏综合症。
