FMK
- RSK inhibitor Fmk
- Soluble in DMSO
- MF: C18H19FN4O2
- MW: 342.37
Description
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.
* FMK (IC50 value 15 nM for RSK2 in vitro) is more potent than another CTKD RSK inhibitor SL-0101 (IC50 value 85 nM for RSK2); while BI-D1870 (Axon 1528) binds at NTKD binding site as a reversible RSK inhibitor.
