BI-D1870

BI-D1870 is an ATP-competitive inhibitor of S6 ribosome for RSK1/2/3/4 with IC50 of 31 nM/24 nM/18 nM/15 nM in cell-free assays, respectively; 10- to 100-fold selectivity for RSK than MST2, GSK-3β, MARK3, CK1 and Aurora B. BI-D1870 exhibits anticancer attributes including the generation of reactive oxygen species (ROS) and increases in endoplasmic reticulum (ER) stress and autophagy.

PF-4708671

PF-4708671 is a cell-permeable inhibitor of p70 ribosomal S6 kinase (S6K1 isoform) with Ki/IC50 of 20 nM/160 nM in cell-free assays, 400-fold greater selectivity for S6K1 than S6K2, and 4- and >20-fold selectivity for S6K1 than MSK1 and RSK1/2, respectively. PF-4708671 induces autophagy. First S6K1-specific inhibitor to be reported.
