There are provided substituted isoquinolin-1(2H)-one derivatives which selectively inhibit the activity of poly (ADP-ribose) polymerase PARP-1 with respect to poly (ADP-ribose) polymerase PARP-2. The compounds of the present invention are therefore useful in treating diseases such as cancer, cardiovascular diseases, central nervous system injury and different forms of inflammation. The present invention also provides methods for preparing these compounds, pharmaceutical compositions comprising these compounds, and methods of treating diseases utilizing pharmaceutical compositions comprising these compounds. A screening method for the identification of compounds capable of binding several PARP proteins, as well the probes used in such method, are further objects of the invention.

Isoquinolin-1 (2H)-one derivatives as PARP-1 inhibitors

The invention provides low molecular weight compounds, namely tetrahydropyrrolo[3,4-c]pyrazoles, showing a high affinity for the ATP pocket of ABL tyrosine kinase. These compounds are thus ATP-competitive tyrosine kinase inhibitors displaying a significant inhibitory potency also, and in particular, towards BCR-ABL inhibitor-resistant T315I ABL mutants. The compounds of the invention find a useful application in the treatment of BCR-ABL inhibitor-resistant ABL-mediated diseases, such as Imatinib-resistant chronic myelogenous leukemia. Moreover, the invention provides a screening method for the identification of compounds capable of binding the ATP pocket of a kinase protein, in particular of the T315I mutant ABL kinase.
