Abstract: Compounds which are 4,7-disubstituted derivatives of 3,4-dihydro-2H-pyrrolo[1,2-a]pyrazin-1-one compounds with the formula or pharmaceutically acceptable salts thereof, their preparation process and pharmaceutical compositions comprising them are disclosed; these compounds are useful in the treatment of diseases caused by and/or associated with an altered protein kinase activity such as cancer, viral infection, prevention of AIDS development in HIV-infected individuals, cell proliferative disorders, autoimmune and neurodegenerative disorders; also disclosed is a process under Solid Phase Synthesis conditions for preparing the compounds of the invention and chemical libraries comprising a plurality of them.

Abstract: Bicyclic pyrazole and isoxazole derivatives of formula (I) and pharmaceutically acceptable salts thereof, as defined in the specification, process for their preparation and pharmaceutical compositions comprising them are disclosed; the compounds of the invention may be useful in therapy in the treatment of diseases mediated by HSP90 protein, like cancer and neurodegenerative disorders.

Abstract: The present invention relates to substituted pyrazolo[4,3-h]quinazoline compounds which modulate the activity of protein kinases and are therefore useful in treating diseases caused by dysregulated protein kinase activity, in particular PIM kinases. The present invention also provides methods for preparing these compounds, pharmaceutical compositions comprising these compounds, and methods of treating diseases utilizing such these compounds or the pharmaceutical compositions containing them.

Abstract: The present invention relates to [1,2,4]triazolo[1,5-c]pyrimidine derivatives of formula (I) which inhibit the activity of Heat Shock Protein Hsp90. The compounds of the invention are therefore useful in treating proliferative diseases such as cancer and neurodegenerative diseases. The present invention also provides processes for preparing these compounds, methods of treating diseases and the pharmaceutical compositions comprising these compounds.

Abstract: The present invention provides tricyclic indoles and (4,5-dihydro) indoles of the formula (I) or a pharmaceutically acceptable salt thereof: wherein the ring A represents a fused pyrazole, pyridine or pyrimidine, means either simple or double carbon-carbon bond and R1, R2 and R3 are as defined in the specification. Further objects of the invention are a process for the preparation of the compounds of the formula (I), pharmaceutical compositions comprising them and methods for treating cell proliferative disorders. As a matter of fact, the compounds of the formula (I) are useful, in therapy, in the treatment of diseases associated with a disregulated protein kinase activity, in particular Cdc7 and AKT kinase activity, like cancer.
