In Vitro JDQ-443 促进磷酸化ERK(pERK)水平的剂量依赖性降低,并促进 KRASG12C 突变细胞系 NCI-H358 和 NCI-H2122 的增殖,其 IC50值分别为 0.018 和 0.063 μM[2]。 JDQ443 与 GDP结合的 KRASG12C 共价且选择性地结合并抑制其与 RAS 开关 II 口袋的低可逆结合亲和力,还能抑制KRASG12C突变和 KRAS G12C/H95、G12C/R68S 和 G12C/Y96 双突变细胞系的增殖[2]。
In Vivo JDQ443(10-100 mg/kg,口服,每天,14天)显示出抗肿瘤活性,并以剂量依赖的方式抑制 KRAS G12C 突变的 CDX 模型的肿瘤生长[2]。 JDQ443(口服,100 mg/kg,每日(JDQ443)+7.5mg/kg,每日两次(TNO155),共36天)与单药 JDQ443 联合使用时,显示出更大的细胞生长抑制或细胞杀死作用[2]。 JDQ443 在 NSCLC 和结直肠肿瘤的 PDX 模型中产生了分类抗肿瘤反应,并通过与其他药物的联合治疗得到改善[2]。
