kras g12c mutant protein inhibitor a-1

KRAS G12C mutant protein inhibitor A-1 can be used in studies about Ras.

SAH-SOS1A TFA is a peptide-based SOS1/KRAS protein interaction inhibitor. SAH-SOS1A TFA binds to wild-type and mutant KRAS (G12D, G12V, G12C, G12S, and Q61H) with nanomolar affinity ( EC 50 =106-175 nM). SAH-SOS1A TFA directly and independently blocks nucleotide association. SAH-SOS1A TFA impairs KRAS-driven cancer cell viability and exerts its effects by on-mechanism blockade of the ERK-MAPK phosphosignaling cascade downstream of KRAS [1] .

PROTAC KRAS G12C degrader-2 (compound 432) is a targeted modulator of K-Ras protein hydrolysis that functions as a bifunctional PROTAC molecule, incorporating a cereblon inhibitor of apoptosis proteins (IAP) ligand on one terminus and a KRAS-binding moiety on the opposite end, thereby enabling selective recruitment of mutant KRAS G12C to the ubiquitin–proteasome system for controlled degradation and mechanistic investigation of KRAS-driven oncogenic signaling pathways.
