生物活性

RET-IN-4 is a potent, selective and orally active RET inhibitor with IC50s of 1.29 nM, 1.97 nM, and 0.99 nM for RET (WT), RET (V804M), and RET (M918T), respectively. RET-IN-4 exhibits better kinases selectivity against JAK2 (IC50 of 4.4 nM) and FLT3 (IC50 of 30.8 nM). RET-IN-4 has anticancer effects[1].

IC50 & Target

IC50: 1.29 nM (RET (WT)), 1.97 nM (RET (V804M)), and 0.99 nM (RET (M918T))[1]

体外研究
(In Vitro)

The proliferation of Ba/F3 cells transformed with NSCLC related KIF5B-RET fusion is effectively suppressed by RET-IN-4 (compound 9) (IC50 of 19 nM). RET-IN-4 displays less ‘off-target’ effects than BLU-667[1].

体内研究
(In Vivo)

RET-IN-4 (compound 9; p.o.; 10-20 mg/kg; p.o.; daily; for 10 days) treatment represses tumor growth driven by KIF5B-RET-Ba/F3 cells in a dose-dependent manner[1].

Animal Model: Immunodeficient nude/nude mice bearing KIF5B-RET Ba/F3 cells[1]
Dosage: 10 mg/kg, 20 mg/kg
Administration: p.o.; daily; for 10 days
Result: The tumor growth was remarkably suppressed.
