生物活性

製品説明 ARS-853は、GDP結合オンコプロテインに結合し、活性化を阻害することで、変異型KRAS駆動シグナル伝達を阻害する選択的共有結合性KRAS(G12C)阻害剤です。ARS-853はアポトーシスも誘導します。
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 this compound resulted in a significant loss of KRAS–CRAF interactions. Consistent with an inactive state of KRASG12C once bound to this chemical, downstream signaling through both MAPK (including pMEK, pERK, and pRSK) and PI3K signaling (pAKT) pathways was inhibited by it 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 this compound. No effects on RAF-RBD binding or downstream signaling were observed in A549 cells (KRASG12S), and the inhibitory effects of it in H358 cells could be rescued by ectopic expression of KRASG12V. KRASG12C is the most potent covalent target of this chemical across more than 2,700 cellular proteins and consistently find that it exerts no effects on cellular signaling or growth in non-KRASG12C cells at concentrations up to 10-fold higher than its KRASG12C potency. It reacts only with the inactive (GDP-bound), but the not the active (GTP-bound), state of KRAS. This compound 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. It traps KRASG12C in a GDP-bound conformation by lowering its affinity for nucleotide exchange factors.

実験の流れ

KRASG12C mutant cells (H358) were treated with ARS853 for 5 hours. The effect on the level of active, or GTP-bound, KRAS was determined by a RAS-binding domain pull-down (RBD:PD) assay and immunoblotting with a KRAS-specific antibody.
