生物活性:
Navtemadlin (AMG 232) is a potent, selective and orally available inhibitor of p53-MDM2 interaction, with an IC50 of 0.6 nM. Navtemadlin binds to MDM2 with a Kd of 0.045 nM.
体内研究:
Navtemadlin (AMG 232) (10, 25, 75 mg/kg, once daily, p.o.) activates p53 pathway activity in vivo.Navtemadlin (10, 25, 75 mg/kg, once daily, p.o.) potently inhibits growth of tumor xenografts in mice.Navtemadlin (10, 25, 75 mg/kg, once daily, p.o.) blocks DNA synthesis and induces apoptosis in vivo.Navtemadlin causes a dose-dependent tumor growth inhibition with an ED50 of 16 mg/kg.Animal Model:Female athymic nude mice (n=10/group) based cancer models.
Dosage:10, 25, 75 mg/kg.
Administration:Once daily by oral gavage.
Result:Resulted in significant tumor growth inhibition across all models. SJSA-1, an MDM2 amplified osteosarcoma model, was the most sensitive to AMG 232 treatment with an ED50 of 9.1 mg/kg. In the highest dose group of 75 mg/kg, 10/10 tumors completely regressed and were undetectable after 10 days of treatment.
体外研究:
Navtemadlin (AMG 232) (10 μM) induces p53 signaling and inhibits tumor cell proliferation in three p53 wild-type tumor cell lines. Navtemadlin potently inhibits proliferation of non-MDM2-amplified HCT116 colorectal cells (IC50=10 nM).
