  Design, synthesis and biological evaluation of 6-pyridylmethylaminopurines as CDK inhibitors

  摘要：

  The cyclin-dependent kinase (CDK) inhibitor seliciclib (1, CYC202) is in phase II clinical development for the treatment of cancer. Here we describe the synthesis of novel purines with greater solubility, lower metabolic clearance, and enhanced potency versus CDKs. These compounds exhibit novel selectivity profiles versus CDK isoforms. Compound alpha SbR-21 inhibits CDK2/cyclin E with IC(50) = 30 nM, CDK7-cyclin H with IC(50) = 1.3 mu M, and CDK9-cyclinT with IC(50) = 0.11 mu M; it (CCT68127) inhibits growth of HCT116 colon cancer cells in vitro with GI(50) = 0.7 mu M; and shows antitumour activity when dosed p.o. at 50 mg/kg to mice bearing HCT116 solid human tumour xenografts.

  Cyclin-dependent kinases (CDKs) and casein kinases 1 (CK 1) are involved in the two key molecular features of Alzheimer's disease, production of amyloid-beta 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 (IC50: 14 nM). Modeling of these molecules into the ATP-binding pocket of CK1 delta provided a rationale for the increased selectivity toward this kinase. 13a was able to prevent the CK1-dependent production of anyloid-beta in a cell model. CDK/CK1 dual-specificity inhibitors may have important applications in Alzheimer's disease and cancers.
