The RSK Inhibitor II, also referenced under CAS 501437-28-1, controls the biological activity of RSK. This small molecule/inhibitor is primarily used for Cell Signaling applications.
Synonym(s):
RSK Inhibitor II, 2-(3,5-Difluoro-4-hydroxy-anilino)-8-isopentyl-5,7-dimethyl-7H-pteridin-6-one, racemic, p90 Ribosomal S6 Kinase Inhibitor II, BI-D1870, BID-1870, BID1870
The racemic mixture of a cell-permeable dihydropteridinone that acts as a potent and selective RSK inhibitor (IC50 ≤31 nM against RSK1, 2, 3, and 4; [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 HEK-293 cells and EGF-stimulated Rat-2 cells (IC50 ~1 µM).
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.

ERK1/2 involvement in cell death remains unclear, although many studies have demonstrated the importance of ERK1/2 dynamics in determining cellular responses. To untangle how ERK1/2 contributes to two cell death programs, we investigated ERK1/2 signaling dynamics during hFasL-induced apoptosis and
