Description

Biochem/physiol Actions

APS-2-79 is a stabilizer of the Kinase suppressor of Ras (KSR) inactive state, resulting in inhibition of oncogenic Ras signaling, antagonizing the Ras–MAPK pathway. KSR is a MAPK scaffold that is regulated allosterically by dimerization with RAF. APS-2-79 was found to bind to the KSR active site with an IC₅₀ value of 120 nM, antagonizing MEK (MAPKK) phosphorylation by RAF. In Ras mutant cell lines, APS-2-79 increased the potency of several MEK inhibitors..
