VUBI1 (SOS1 Activator 1) is a benzimidazole-derived small molecule that acts as a potent activator of the guanine nucleotide exchange factor SOS1, with a dissociation constant (Kᴅ) of 44 nM. It promotes RAS activation by enhancing RAS-GTP formation and modulates downstream ERK phosphorylation, thereby influencing RAS–MAPK signaling. In addition, VUBI1 serves as a functional ligand for the development of PROTAC-based degraders, such as PROTAC SOS1 Degrader-1, to induce targeted SOS1 degradation. VUBI1 is a valuable compound for studying RAS pathway regulation and its role in cancer biology.
