Biochem/physiol Actions
BAY-293 selectively inhibits SOS1-mediated KRAS activation (IC50 = 52 nM; 50 nM wt or G12C hKRAS & 10 nM SOS1cat) via direct SOS1 binding, blocking SOS1-KRAS interaction (IC50 = 21 nM; 10 nM hSOS1cat & 5 nM hKRAS G12C) without affecting (IC50 >20 μM) CRAF RBD-KRAS interaction, KRAS G12C activation by SOS2, Cdc42 activation by DBS, or EGFR kinase activity. BAY-293 downregulates cellular active RAS (IC50 = 200 nM/Calu-1, 410 nM/HeLa) and downstream ERK phosphorylation (K-562, 150 nM/Calu-1) with good target selectivity as assessed over 358 kinases (<37% inhibition at 1 μM) and a panel of 77 GPCRs, transporters, nuclear receptors and enzymes.

Since the late 1980s, mutations in the RAS genes have been recognized as major oncogenes with a high occurrence rate in human cancers. Such mutations reduce the ability of the small GTPase RAS to hydrolyze GTP, keeping this molecular switch
