A new series of 2,6,9-trisubstituted purines, structurally related to the cyclin-dependent kinase (CDK) inhibitor Roscovitine, has been synthesized. These compounds mainly differ by the substituent on the C-2 position which encompasses a diol group. These

The present invention concerns a method of treatment of polycystic diseases or of reducing and/or avoiding cyst formation in a patient with cystic disease, which comprises at least one step consisting in administering to said patient an effective amount of a 2,6,9-trisubstituted purine compound of formula (VII): wherein A represents alternatively a (A.1) or (A.2) group.

Cyclin-dependent kinases (CDKs) and casein kinases 1 (CK1) are involved in the two key molecular features of Alzheimer's disease, production of amyloid-β peptides (extracellular plaques) and hyper-phosphorylation of Tau (intracellular neurofibrillary tangles). A series of 2,6,9-trisubstituted purines, structurally related to the CDK inhibitor roscovitine, have been synthesized. They mainly differ by the substituent on the C-6 position. These compounds were screened for kinase inhibitory activities and antiproliferative effects. Several biaryl derivatives displayed potent inhibition of both CDKs and CK1. In particular, derivative 13a was a potent inhibitor of CDK1/cyclin B (IC50: 220 nM), CDK5/p25 (IC50: 80 nM), and CK1 (IC 50: 14 nM). Modeling of these molecules into the ATP-binding pocket of CK1δ provided a rationale for the increased selectivity toward this kinase. 13a was able to prevent the CK1-dependent production of amyloid-β in a cell model. CDK/CK1 dual-specificity inhibitors may have important applications in Alzheimer's disease and cancers.
