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: The present invention is related to a family of phenyl-prenyl derivatives of formula (I), and to their use in the treatment of cognitive, neurodegenerative or neuronal diseases or disorders, such as Alzheimer's disease or Parkinson's Disease. The present invention also relates to pharmaceutical compositions comprising the same. Further, the present invention is directed to the compounds of formula (I) for medical use, particularly for the use for the treatment and/or prevention of a cognitive, neurodegenerative or neuronal disease or disorder, and to the use of the compounds in the manufacture of a medicament for the treatment and/or prevention of a cognitive, neurodegenerative or neuronal disease or disorder.

Abstract: The invention is directed to a compound of formula (I) Having VDCC blocking activity. These compounds are useful for the treatment of a series of human diseases and conditions, especially cognitive or neurodegenerative diseases or conditions.

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.
