Product description

Description

BAY-293, a valuable chemical probe, blocks RAS activation via disruption of the KRAS-SOS1 interaction with an IC50 of 21 nM. BAY-293 is a potent inhibitor of Son of Sevenless 1 (SOS1). SOS1 is the guanine nucleotide exchange factor (GEF) and activator of RAS[1].


IC50 & Target

________________________________________________________________________________________

KRAS-SOS1

21 nM (IC50)


In Vitro

_________________________________________________________________________________________

BAY-293 inhibits the activation of RAS in HeLa cells, with IC50 values in the submicromolar range[1].
BAY-293 (595 nM-3580 nM; 72 hours) shows efficient antiproliferative activity against wild-type KRAS cell lines (K-562, MOLM-13) and cell lines with KRASG12C mutation (NCI-H358, Calu-1)[1].
BAY-293 efficiently inhibits pERK levels in K-562 cells after incubation for 60 min without affecting total protein levels of ERK[1].
