Abstract: 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.

Abstract: The invention is related to compound which comprises at least one radical C?Y, Y being O or S, and an oxidable and non protonable nitrogen atom N wherein the distance (d) between the at least one carbon atom of the radical group C?Y and the nitrogen atom, when oxidized, is comprised between 0.3 and 0.8 nanometers. The invention is related to new heterocyclic compounds defined by formula G, their preparation, to pharmaceutical compositions comprising them and to their use as therapeutic agents, particularly in the treatment of neurodegenerative or Alzheimer disease.
