In eukaryotes, protein phosphorylation of serine, threonine or tyrosine residues by protein kinases plays an important role in many cellular processes. Members of the protein kinase CK1 family usually phosphorylate residues of serine that are close to other phosphoserine in a consensus motif of pS-X-X-S, and they are implicated in the regulation of a variety of physiological processes as well as in pathologies like cancer and Alzheimer's disease. Using a structure-based virtual screening (SBVS) approach we have identified two anthraquinones as novel CK1 delta inhibitors. These amino-anthraquinone analogs (derivatives 1 and 2) are among the most potent and selective CK1 delta inhibitors known today (IC50 = 0.3 and 0.6 mu M, respectively). (C) 2008 Elsevier Ltd.
