生物活性

Adagrasib (MRTX849) is a potent, orally-available, and mutation-selective covalent inhibitor of KRAS G12C with potential antineoplastic activity. Adagrasib covalently binds to KRAS G12C at the cysteine at residue 12, locks the protein in its inactive GDP-bound conformation, and inhibits KRAS-dependent signal transduction.

体外研究

MRTX849 (0.1-10000 nM; 3 天 /2D 条件,12 天 /3D 条件) 对绝大多数 KRAS G12C 突变体细胞系的生长有明显的抑制作用,其 IC50 在 2D 条件下为 10~973 nM,3D 条件为 0.2~1042 nM。
MRTX849 (0.24-1000nM; 24 小时) 抑制 KRAS 依赖的信号转导靶点,包括 ERK1/2 磷酸化 (Thr202/Tyr204 ERK1; pERK)、S6 磷酸化

Cell Viability Assay

Cell Line: MIA PaCa-2, H1373, H358, H2122, SW1573, H2030, KYSE-410 cells (G12C); H1299 (WT); A549 (G12S), HCT116 (G13D) cells
Concentration: 0.1, 1, 10, 100, 1000, 10000 nM
Incubation Time: 24 hours
Result: Inhibits cell growth in the vast majority of KRAS G12C-mutant cell lines with IC50 values ranging between 10 and 973 nM in the 2D format and between 0.2 and 1042 nM in the 3D format.

Western Blot Analysis

Cell Line: MIA PaCa-2 cells
Concentration: 0.24, 0.5, 1.0, 2.0, 3.9, 7.8, 15.6, 31.3, 62.5, 125, 250, 500, 1000 nM
Incubation Time: 24 hours
Result: Inhibits KRAS-dependent signaling targets including ERK1/2 phosphorylation (Thr202/Tyr204 ERK1; pERK), S6 phosphorylation (RSK-dependent Ser235/236; pS6) and expression of the ERK-regulated DUSP6, each with IC50s in the single-digit nanomolar range in cell lines.
体内研究

MRTX849 (1-100 mg/kg;口腔灌胃.;每日一次至第 16 天) 在耐受良好的剂量范围内显示剂量依赖性抗肿瘤疗效,MRTX849 的最大有效剂量在 30-100 mg/kg/天之间。

Animal Model: MIA PaCa-2 model (6-8-week-old, female, athymic nude-Foxn1 nu mice)
Dosage: 1, 3, 10, 30 and 100 mg/kg
Administration: Oral gavage; daily until Day 16
Result: Rapid tumor regression was observed at the earliest posttreatment tumor measurement and animals in the 30 and 100 mg/kg cohorts exhibited evidence of a complete response at study Day 15. Dosing was stopped at study Day 16 and all 4 mice in the 100 mg/kg cohort and 2 out of 7 mice in the 30 mg/kg cohort remained tumor-free through study Day 70.
