RM-041 是一种选择性、口服有效的 KRASG13C(ON) 抑制剂,可与 KRASG13C(ON)Cyclophilin A 形成共价复合物。RM-041 通过空间位阻阻断 RAS 效应蛋白的结合,随后与 Cys-13 共价结合形成不可逆抑制复合物,抑制 KRASG13C 突变癌细胞的增殖。RM-041 可在细胞和异种移植肿瘤模型中诱导 KRASG13C 肿瘤消退。RM-041 与上游节点抑制剂 (如 SHP2 抑制剂) 联用时,可发挥协同效果。RM-041 可用于非小细胞肺癌的研究。

生物活性

RM-041 is a selective, orally active KRASG13C (ON) inhibitor that forms a covalent complex with KRASG13C (ON) and Cyclophilin A. RM-041 blocks the binding of RAS effector proteins via steric hindrance, and then covalently binds to Cys-13 to form an irreversible inhibitory complex, thereby inhibiting the proliferation of KRASG13C mutant cancer cells. RM-041 induces regression of KRASG13C tumors in cellular and xenograft tumor models. RM-041 exerts a synergistic effect when combined with upstream node inhibitors (such as SHP2 inhibitors). RM-041 can be used for the research of non-small cell lung cancer[1].

IC50 & Target

KRAS G13D

 

体外研究
(In Vitro)

相较于 KRASG12CKRASG13C 表现出更高的自发性核苷酸交换速率,这降低了其对 GEF (鸟苷酸交换因子) 重新加载的依赖性,同时也降低了其对上游抑制剂 (如 SHP2SOS1) 的敏感性。所以针对 KRASG13C 突变肿瘤的疗法有必要直接抑制 KRASG13C。此外,KRASG13C 对特定的 GAP (鸟苷三磷酸酶激活蛋白) 表现出独特的敏感性,其中包括 NF1[1]
临床前联合用药策略
利用 RM-041 特异性抑制突变型 KRASG13C,同时联合靶向 SHP2 等上游关键节点,以削弱野生型 RAS 信号传导所产生的协同作用[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
