生物活性

LJH685 is a potent, ATP-competitive and selective RSK inhibitor, inhibits RSK1, 2, and 3 biochemical activities with IC50s of 6, 5, 4 nM, respectively[1].

IC50 & Target

IC50: 6 nM (RSK1), 5 nM (RSK1), 4 nM (RSK1)[1]

体外研究
(In Vitro)

LJH685 (0.01-100 μM; 72 hours) efficiently inhibits the growth of MDA-MB-231 and H358 cells in soft agar with EC50s of 0.73 and 0.79 μM, respectively[1].
LJH685 (0.1-10 μM; 4 hours) efficiently reduces phosphorylation of YB1 at submicromolar concentrations and causes nearly complete inhibition at higher concentrations[1].

上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay[1]

Cell Line: MDA-MB-231, H358 cells
Concentration: 0.01, 0.1, 1, 10, 100 μM
Incubation Time: 72 hours
Result: The growth in soft agar was efficiently inhibited with EC50 values of 0.73 and 0.79 μM in MDA-MB-231 and H358, respectively.

Western Blot Analysis[1]

Cell Line: MDA-MB-231, H358 cells
Concentration: 0.1, 0.3, 1, 3, 10 μM
Incubation Time: 4 hours
Result: Efficiently reduced phosphorylation of YB1 at submicromolar concentrations and caused nearly complete inhibition at higher concentrations.
