Background: Roscovitine is a potent and selective inhibitor of cyclin-dependent protein kinases (CDKs). It is selective forCDK1/ CycB (IC50 = 0.65 µM), CDK2/CycA (IC50 = 0.7 µM), CDK2/CycE (IC50 = 0.7 µM), CDK3/CycE (IC50 =1.4 µM), CDK5/p25 (IC50 = 0.2 µM), CDK7/CycH (IC50 =0.5 µM), CDK9/CycT1 (IC50 =0.6 µM), but not for CDK4 or CDK6 (IC50 >100µM). The compound inhibits the proliferation of mammalian cell lines with an average IC50 of 16 µM and inhibits M phase promoting factor (MPF) kinase activity. Furthermore, PDXK was identified as a (R)-roscovitine-binding protein. Crystal structure analysis revealed, that interaction occurs with the pyridoxal – binding site rather than the ATP – binding site of PDXK. The effects of (R)-roscovitine on the catalytic activity of PDXK are rather limited.
