APS-2-79 (2002381-31-7) Description:

APS-2-79 is a KSR-dependent MAPK modulator. APS-2-79 modulates KSR-dependent MAPK signalling by antagonizing RAF heterodimerization as well as the conformational changes required for phosphorylation and activation of KSR-bound MEK (mitogen-activated protein kinase kinase). APS-2-79 increased the potency of several MEK inhibitors specifically within Ras-mutant cell lines by antagonizing release of negative feedback signalling, demonstrating the potential of targeting KSR to improve the efficacy of current MAPK inhibitors. Co-targeting of enzymatic and scaffolding activities within Ras-MAPK signalling complexes is a therapeutic strategy for overcoming Ras-driven cancers.
