RSK Inhibitor II-CAS 501437-28-1-Calbiochem

C₁₉H₂₃F₂N₅O₂

391.42

The racemic mixture of a cell-permeable dihydropteridinone that acts as a potent and selective RSK inhibitor (IC₅₀ = 31, 24, 18, and 15 nM against RSK1, 2, 3, and 4, respectively; [ATP] = 100 µM) by targeting RSK N-terminal kinase domain in an ATP-competitive manner, while inhibiting 11 other kinases only at higher concentrations (IC₅₀ ≥100 nM) and displaying little activity against 39 others. Shown to selectively inhibit RSK-dependent, but not RSK-independent, cellular protein phosphorylations in PMA-stimulated human HEK-293 cells and EGF-stimulated rat Rat-2 cells (IC₅₀ ~1 µM). A useful pharmacological reagent for studying RSK-mediated cellular signaling events.
