Abstract: The present invention provides the use of a compound of formula (I); wherein: n is 0, 1, 2, or 3, the bonds shown with the dashed lines are saturated, or unsaturated with one or more double bonds; R, and R?are independently selected from hydrogen, alkyl, aryl, —OH, —OR? —SH, —SR?—NH, —NHR?, ?O, ?NH, ?NR?; R? is independently selected from alkyl, aryl, in the preparation of a medicament for the treatment of a disease requiring a GSK-3 inhibitor. Also provided is a compound of formula (II); wherein n is 0, 1, 2, or 3 the bonds shown with the dashed lines are saturated, or unsaturated with one or more double bonds. Also provided are methods of treating chronic neurodegenerative conditions.

Abstract: A family of compounds of formula (I) wherein: X is one of the following radicals: which behaves as dual site acetyl-cholinesterase inhibitors and which are especially useful for the treatment of cognitive disorders as senile dementia, cerebrovascular dementia, mild cognition impairment, attention deficit disorder, and/or neurodegenerative dementing disease with aberrant protein aggregations as specially Alzheimer's disease, Parkinson disease, ALS, or prion diseases, as Creutzfeldt-Jakob disease or Gerst-mann-Straussler-Scheiner disease.

Abstract: Provided are thiadiazolidine compounds of formula I wherein R1 is an organic group having at least 8 atoms selected from C or O, which is not linked directly to the N through a —C(O)— and comprising at least an aromatic ring, and their pharmaceutical compositions. These compounds are selective GSK-3 inhibitors and have improved bioavailability. They are useful for the treatment of GSK-3 mediated diseases, among others Alzheimer's disease, type II diabetes, depression and brain injury.

Abstract: The invention provides compounds of formula: which have a tacrine moiety connected to an heterocyclic moiety through a linker. Through careful selection of the substituents and the linker, the activity and selectivity towards acetylcholinesterase can be modulated. The compounds show potent AChE inhibition activities together with modifications in the ?-amyloid aggregation properties by binding simultaneously to the catalytic and peripheral AChE sites. They are useful in the treatment of AChE mediated diseases, such as the Alzheimer's disease.
