Selected Approaches to Disrupting Protein–Protein Interactions within the MAPK/RAS Pathway

Abstract: Within the MAPK/RAS pathway, there exists a plethora of protein–protein interactions (PPIs). For many years, scientists have focused efforts on drugging KRAS and its effectors in hopes to provide much needed therapies for patients with KRAS-mutant driven cancers. In this review, we focus on recent strategies to inhibit RAS-signaling via disrupting PPIs associated with SOS1, RAF, PDEδ, Grb2, and RAS.

“…These "switch" regions are dynamic allosteric binding pockets where RAS proteins switch between Peanlikhit et al 2024 an inactive state when bound to guanosine diphosphate (GDP) and an active state when bound to guanosine triphosphate (GTP) [82,83]. This process is facilitated by the binding of guanine nucleotide exchange factors (GEFs) such as Son of Sevenless (SOS1) to the Switch regions, which promote the dissociation of GDP and association of GTP, leading to oncogenic activation of mutated KRAS proteins [84]. Therefore, apigenin, flavonoids, or drugs that bind to these Switch regions would prevent the binding of GEFs to the Switch regions, preventing the oncogenic activation of mutated KRAS proteins.…”

“…Recent studies also investigated other inhibitory molecules such as MRTX1133 and JAB-23000 that are selective inhibitors of KRAS G12D and KRAS G12V, respectively. A phase 1 trial testing RMC-6236, a triple inhibitor of KRAS (G12V, G12D, G13C, G13D, Q61H), NRAS (Q61X) and HRAS mutants, is also underway, with optimistic outcomes [ 84 , 85 ]. Nonetheless, the applicability of such molecules in the field of hematology has still been restricted due to various factors.…”
