A compound of 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 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 and stereisomers thereof. The compounds of formula (I) are potent in the treatment of neurodegenerative diseases such as Alzheimer's disease.
公式(I)的化合物,其中点线表示至少存在一个双键;n = 0至4;当n = 1时,R3和R4为H,或者R3和R4也可以形成碳原子之间的双键;m = 0,1或2;Z为CH或N,或者Z为C,且-CHR3-通过双键与环戊酮相连;或者-(-)m-不存在,而Z为NH,> N-烷基,> N-苯基,> N-苄基或> N杂环基;R8为烷基,芳基或杂环基,可以选择性地被取代;EWG代表从COOR,COSR,CONRR',CN,COR,CF3,SOR,SO2R,SONRR',SO2NRR',NO2,卤素,杂环中选择的电子吸引基;以及其药物盐和立体异构体。公式(I)的化合物在治疗神经退行性疾病,如阿尔茨海默病方面具有强效作用。
