A compound of the formula (I) in which the dotted lines indicate the presence of at least one double bond; n = 0 to 4; R3 and R4 are H, or when n = 1, R3 and R4 can also form together a double bond between the carbon atoms, and m = 0, 1 or 2, Z is CH or N or Z is C and -CHR3- is =CH- linked by the double bond to the cyclopentanone; or -(-)m- is absent, and Z is NH, >N-alkyl, >N-phenyl, >N-benzyl or >N-heteroaryl; R8 is alkyl, aryl or heteroaryl which can be optionally substituted; EWG represents an electron withdrawing group selected from the group comprising COOR, COSR, CONRR', CN, COR, CF3, SOR, SO2R, SONRR', SO2NRR', NO2, halogen, heteroaryl; and the pharmaceutical salts or tautomers thereof.
The compounds of formula (I) are potent in the treatment of neurodegenerative diseases such as Alzheimer's disease.
式(I)的化合物,其中虚线表示至少存在一个双键;n = 0到4;R3和R4为H,或当n = 1时,R3和R4也可以一起形成碳原子之间的双键,m = 0、1或2,Z为CH或N,或Z为C且-CHR3-为=CH-,通过双键与环戊酮相连;或-(-)m-不存在,Z为NH,>N-烷基,>N-苯基,>N-苄基或>N-杂环烷基;R8为烷基、芳基或杂环烷基,可选择性地取代;EWG代表从COOR、COSR、CONRR'、CN、COR、CF3、SOR、SO2R、SONRR'、SO2NRR'、NO2、卤素、杂环烷基组成的电子吸引基团;以及其药用盐或互变异构体。式(I)的化合物在治疗像阿尔茨海默病这样的神经退行性疾病中具有很强的作用。
