Compound status: 
Historic compound: While this compound has been used to interrogate specific protein targets, it is not a chemical probe and should not be used in assays that depend on a potent and selective modulator of the protein.
Note about activity: 

Intended target: RSKs; In a panel of 442 kinases, 10 uM LJI308 inhibited 60 off-target kinases by >50% and 24 off-target kinases by >80%(BMPR2, DYRK1B, PCACalpha, TIE2, CLK3, CSNK1E, DAPK1, DAPK2, DAPK3, DYRK1A, FLT3(N841I), HIPK1, HIPK2, HIPK3, HIPK4, IRAK1, IRAK3, LOK, MAP3K3, MEK4, PIP5K2C, RPS6KA4, S6K1, TRKC).
