BI-D1870 is a cell-permeable inhibitor of the p90 RSK isoforms with IC50 values of 31nM, 24nM, 18nM and 15nM for RSK1, RSK2, RSK3 and RSK4 respectively [1].
BI-D1870 is a derivative of dihydropteridinone and found to be a remarkably specific inhibitor of RSK isoforms. It is an ATP-competitive inhibitor. When the concentrations of ATP are 10μM and 100μM, the IC50 values of BI-D1870 against RSK1 and RSK2 are 5nM, 10nM and 10nM, 20nM, respectively. BI-D1870 also inhibits RSK3 and RSK4 with IC50 values of 18nM and 15nM respectively, when ATP is 100μM. The inhibition activity of BI-D1870 against RSK is more than 500-fold greater than some other AGC kinases suggesting BI-D1870 as a specific inhibitor of RSK. In addition, BI-D1870 is reported to induce the phosphorylation of ERK1/ERK2 and the subsequent phosphorylation of CREB in Rat-2 cells [1].
