ARS-853 生物活性

描述 ARS-853 is a selective, covalent inhibitor of KRAS G12C, featuring an IC50 of 2.5 μM. By attaching to the GDP-bound form of the mutant KRAS oncoprotein, ARS-853 blocks its activation, thereby inhibiting KRAS-driven signaling pathways[1].[2]. In experiments with KRASG12C-mutant lung cancer cells, ARS-853, at a concentration of 10 μM, dramatically reduces GTP-bound KRAS levels by over 95%. Its inhibition of cell proliferation, with an IC50 mirroring that for its target binding, alongside its suppression of effector signaling and induction of apoptosis in certain KRASG12C mutant cell lines, highlights its selective action against KRASG12C mutations without affecting non-mutant models[1]. ARS-853 inhibits mutant KRAS-driven signaling by binding to the GDP-bound oncoprotein and preventing activation[2].
作用机制 ARS-853 covalently inhibits KRAS G12C and targets the GDP-bound, inactives state and prevents subsequent activation.[1][2]
