      Description
      OverviewA cell-permeable (R)-DRF053 (Cat. No. 219494) analog that acts as an ATP-binding pocket-targeting CDK/CK1 dual-specific inhibitor (IC50 = 0.09, 0.072, 0.041, 0.11, 1.10, 0.18, and 0.40 µM against CDK1/B, CDK2/A, CDK2/E, CDK5/p25, CDK7/H, CDK9/T, and CK1δ/ε, respectively). As is the case with (R)-DRF053, (R)-CR8 inhibits CDK/CK1 more effectively than (R)-Roscovitine (Cat. Nos. 550360 & 550364), while maintaining similar selectivity profile over other types of kinases (IC50 = 3.6, 3.6, and 12.0 µM against Dyrk1A, Erk2, and GSK-3α/β, respectively). Both the (R)-CR8 and (S)-enantiomer (Cat. No. 203882) are much more effective than (R)-Roscovitine in apoptosis induction in cell cultures.
