• 产品描述： MRTX0902 is an orally active and potent SOS1 inhibitor with an IC50 of 46 nM (WO2021127429A1; Example 12-10)

• 靶点： KRAS-SOS1:46 nM (IC50);Raf

• 体外研究：
  MRTX0902 (compound 32) (1 μM; 0, 2, 4, 8, 15, and 30 minutes) shows a moderate Clint value of 195 mL/min/kg in human liver microsome and a low lipophilicity with cLogP of 3.4.
  MRTX0902 displays high selectivity on SOS1 (Ki=2 nM) over SOS2 and EGFR (both Ki values >10,000 nM), MRTX0902 inhibits MKN1 cells with an IC50 value of 29 nM.

• 体内研究：
  MRTX0902 (compound 32) (25, 50 mg/kg; p.o.; twice daily; 25 d) shows anti-tumor effect in mouse model and results tumor regression. MRTX0902 (1-3 mg/kg for i.v. or 10-30 mg/kg for p.o.; single dose) exhibits good brain penetrance, low clearance, and high bioavailability. Animal Model: Female CD-1 mice Dosage: 50 mg/kg Administration: Oral gavage; twice daily; 1 day Result: Resulted free drug exposure in the brain as well as the efflux ratio in the Caco-2 assay (ER = 1.5).Showed short half-life of the compound in mice (T1/2 = 1.3 h). Animal Model: MIA PaCa-2 xenograft model in mouse Dosage: 25 mg/kg; 50 mg/kg Administration: Oral gavage; twice daily; 25 days Result: Reduced tumor growth by 41% and 53% at 25 mg/kg and 50 mg/kg administration.
