Summary
LJI308 is a potent pan- ribosomal S6 kinase (RSK) inhibitor, with IC 50 s of 6 nM, 4 nM, and 13 nM for RSK1 , RSK2 , and RSK3 , respectively. LJI308 inhibits the phosphorylation of RSK (T359/S363) and YB-1 (S102) after irradiation, treatment with EGF , and in cells expressing a KRAS mutation [1] [2] .
In Vitro
LJI308 inhibits S6K1 with an IC
50
of 0.8 μM
[1]
.
LJI308 inhibits YB-1 phosphorylation in CRC cells at concentrations of 5 to 25 μM. In a dose kinetics experiment, LJI308, starting at 2.5 μM, inhibits YB-1 phosphorylation in the KRAS mutated TNBC cell line MDA-MB-231 by approximately 86%. LJI308 effectively blocks RSK and YB-1 phosphorylation after EGF stimulation and after irradiation in KRAS wild-type HBL-100 cells
[2]
.
LJI308 (1-10 μM; 96 hours) decreases cell viability by up to 90%
