RSK

AT7867 is a novel and potent inhibitor of both AKT and the downstream kinase p70 S6 kinase (p70S6K) and also of protein kinase A.

SL 0101-1 is a selective inhibitor of p90 ribosomal S6 kinase (RSK) (IC50 = 89 nM for RSK2). It also inhibits the growth of MCF-7 human breast cancer cells with no effect on the normal breast cell line.

FMK is potent, highly specific and irreversible inhibitor of p90 ribosomal protein S6 kinase RSK1 and RSK2; Fmk binds in the CTKD ATP-binding site and inhibits RSK autophosphorylation at Ser386. Fmk induces significant apoptosis in human FGFR3-expressing, t(4;14)-positive multiple myeloma cells.

BI-D1870 is a potent and specific inhibitor of the p90 ribosomal S6 kinase (RSK) isoforms in vitro and in vivo, which inhibits RSK1, RSK2, RSK3 and RSK4 in vitro with an IC50 of 10?€?30 nM.

AT13148 is a novel oral multi-AGC kinase inhibitor with potent pharmacodynamic and antitumor activity, which shows a distinct mechanism of action from other AKT inhibitors.

LJI308 is a new and potent pan-RSK inhibitor, with IC50 of 6 nM, 4 nM, and 13 nM for RSK1, RSK2, and RSK3, respectively.

AT7867 dihydrochloride is a potent ATP-competitive inhibitor of Akt1/2/3 and p70S6K/PKA with IC50 of 32 nM/17 nM/47 nM and 85 nM/20 nM, respectively, little activity outside the AGC kinase family.

LY-2584702 tosylate salt is an orally available inhibitor of p70S6K signaling; inhibits p70S6K and prevents phosphorylation of the S6 subunit of ribosomes.
