Adagrasib (MRTX849) 是一种有效,口服可用,突变选择性的KRAS G12C共价抑制剂,具有潜在抗肿瘤活性的。Adagrasib 在半胱氨酸 12 残基处与 KRAS G12C 共价结合,将蛋白锁定在非活性的 GDP 结合构象中,并抑制 KRAS 依赖性信号转导。
生物活性 | Adagrasib (MRTX849) is a potent, orally-available, and mutation-selective covalent inhibitor ofKRAS G12Cwith 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[1][2]. |

体内研究 (In Vivo) | 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[1]。
Animal Model: | MIA PaCa-2 model (6-8-week-old, female, athymic nude-Foxn1 nu mice)[1] | 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. |
