Small molecule that stabilizes the KSR (Kinase suppressor of Ras) inactive state and antagonizes oncogenic Ras signalling (IC50 value 120 nM against ATP-biotin probe-labelling of KSR2). Furthermore, APS-2-79 modulates KSR-dependent MAPK signaling, and increases the potency of several MEK inhibitors, specifically within Ras-mutant cell lines by antagonizing release of negative feedback signaling.
