BI-D1870
Cat No.
CEI-0902
Description
BI-D1870 is an ATP-competitive inhibitor of S6 ribosome for RSK1/2/3/K4 with IC50 of 31 nM/24 nM/18 nM/15 nM, respectively; 10- to 100-fold selectivity for RSK than MST2, GSK-3β, MARK3, CK1 and Aurora B.
CAS No.
501437-28-1
Molecular Weight
391.42
Storage
2 years -20 centigrade Powder; 2 weeks 4 centigrade in DMSO; 6 months -80 centigrade in DMSO.
Targets
RSK1, RSK2, RSK3, RSK4
IC50
31 nM; 24 nM; 18 nM; 15 nM
Molecular Formula
C19H23F2N5O2
Chemical Name
6(5H)-Pteridinone, 2-[(3,5-difluoro-4-hydroxyphenyl)amino]-7,8-dihydro-5,7-dimethyl-8-(3-methylbutyl)-
Solubility
DMSO 78 mg/mL; Water <1 mg/mL; Ethanol <1 mg/mL
In vitro
BI-D1870 inhibits RSK1, RSK2, RSK3 and RSK4 with an IC50 of 10–30 nM, but does not significantly inhibit ten other AGC kinase members and over 40 other protein kinases tested at 100-fold higher concentrations. BI-D1870 is cell permeant and prevents the RSK-mediated phorbol ester- and EGF -induced phosphorylation of glycogen synthase kinase-3β and LKB1 in human embry-onic kidney 293 cells and Rat-2 cells. BI-D1870 does not affect the agonist-triggered phosphorylation of substrates for six other AGC kinases. Moreover, BI-D1870 does not suppress the phorbol ester- or EGF-induced phosphorylation of CREB.
