Information
ARS-853 (ARS853) ARS-853 is a selective, covalent KRAS(G12C) inhibitor that inhibits mutant KRAS-driven signaling by binding to the GDP-bound oncoprotein and preventing activation. ARS-853 also induces apoptosis .
Targets
K-Ras(G12C) (in H358 cells) 2.5 μM
In vitro
ARS-853 treatment of KRASG12C cells led to a dose-dependent and nearly complete inhibition of CRAF-RBD (RBD)-mediated pulldown of KRAS from lysates, with an IC50 of approximately 1 μmol/L. Treatment of H358 cells by ARS-853 resulted in a significant loss of KRAS–CRAF interactions. Consistent with an inactive state of KRASG12C once bound to ARS-853, downstream signaling through both MAPK (including pMEK, pERK, and pRSK) and PI3K signaling (pAKT) pathways was inhibited by ARS-853 in H358 and other KRASG12C cell lines. The inhibition of RAF-RBD pulldown and KRAS downstream signaling was sustained over a period of 72 hours, accompanied by G1 cell-cycle arrest, loss of Cyclin D1 and Rb expression, and an increase in the cell-cycle inhibitor p27 KIP1. In addition, hallmarks of apoptosis, including cleaved PARP and increases in sub-diploid DNA, were observed in H358 cells following treatment with ARS-853. No effects on RAF-RBD binding or downstream signaling were observed in A549 cells (KRASG12S), and the inhibitory effects of ARS-853 in H358 cells could be rescued by ectopic expression of KRASG12V. KRASG12C is the most potent covalent target of ARS-853 across more than 2,700 cellular proteins and consistently find that this compound exerts no effects on cellular signaling or growth in non-KRASG12C cells at concentrations up to 10-fold higher than its KRASG12C potency. ARS-853 reacts only with the inactive (GDP-bound), but the not the active (GTP-bound), state of KRAS. ARS853 reduced KRAS-GTP levels and ERK phosphorylation in human embryonic kidney 293 (HEK293) or H358 cells engineered to express KRASG12C but not in those expressing KRASG12C/A59G. ARS853 traps KRASG12C in a GDP-bound conformation by lowering its affinity for nucleotide exchange factors.
