A cell-permeable pyrazolopyrimidine compound that acts as a potent, ATP-competitive and reversible inhibitor of S6K1 (p70 ribosomal protein S6 kinase 1; IC50=9.1nM) with ~2,400 reduced activity towards Akt (IC50=22uM). Shown to completely block rpS6-Ser240/244 phosphorylation in L6 cells at 2.5uM without inducing pAkt-Thr308 and Ser473, and display substantial selectivity in a 219-kinase panel (1uM of DG2 in the presence of 10uM of ATP; IC50 ≥50%; Clk1, Clk2, Dyrk1A, Dyrk3, Flt3, Flt3-D835Y, Flt4, GSK-3a/b, R, MAP4K4, Mink1, PKA, PRKG1, PRKG2, Ret-V804L, Ret-Y791F, RSK1, RSK3, RSK2, MSK2, MSK1 and p70S6K).
