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.

Abstract: Compounds of general formula (I): where A, E, G, X, Y and the bond - - - take various meanings are of use in the preparation of a pharmaceutical formulation, for example in the treatment of a disease in which GSK-3 is involved, including Alzheimer's disease or the non-dependent insulin diabetes mellitus, or hyperproliferative disease such as cancer, displasias or metaplasias of tissue, psoriasis, arteriosclerosis or restenosis.

Abstract: The invention provides butyrylcholinesterase inhibitors of formula (I), which contain an heterocyclic moiety and a 4 piperidine moiety with a linker in between. The compounds show a very high activity and selectivity towards BuChE, making them useful for the treatment and/or prophylaxis of cognitive disorders and/or neurodegenerative disorders.

Abstract: The invention provides compounds having a spiro heterocyclic unit connected through a linker of a certain length to another spiro cycle, an imidazole ring or an amide group. Some of these compounds have been obtained from Aplysinia cavernicola and a mixture of Aplysina fulva and Oceanapia. The compounds exhibit VDCC blocker activity; some also show acetylcholinesterase and butyrylcholinesterase inhibition activities. Therefore they are useful in the treatment of cognitive and neurodegenerative disorders, such as brain ischemia, stroke, cognitive disorders as senile dementia, cerebrovascular dementia, mild recognition impairment, attention deficit disorder, and/or neurodegenerative dementing disease with aberrant protein aggregations as specially Alzheimers's disease or condition, or prion disease as Creutzfeld-Jakob disease or Gerstmann-Straussler-Scheinker disease.
