    Navtemadlin purchased from MCE. Usage Cited in: Cell Death Discov. 2020 Jul 6;6:57.

    The effect of AMG-232 on the p53 signaling pathway, and the expression of IL-6 and PD-L1 at different drug doses is assessed by immunoblotting. AMG-232 treatment leads to activation of the p53 signaling pathway in the cancer cells in a dose-dependent manner. The effect of significant reduction in IL-6 expression is observed with AMG-232 in a dose-dependent manner.

    Description

    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[1][2].

    IC50 & Target

    IC50: 0.6 nM (p53-MDM2 interaction)[1]
    Kd: 0.045 nM (MDM2)[1]

    In Vitro

    Navtemadlin (AMG 232) (10 μM) induces p53 signaling and inhibits tumor cell proliferation in three p53 wild-type tumor cell lines[1].
    Navtemadlin potently inhibits proliferation of non-MDM2-amplified HCT116 colorectal cells (IC50=10 nM)[3].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Cell Viability Assay[1]

    Cell Line: SJSA-1, HCT116, ACHN, NCI-H460, MOLM-13, RKO, MCF7, 22RV1, HT-29, PC-3, NCI-H82, NCI-SNU1, MG-63, NCI-H2452, SW982, C32, SK-HEP-1, A375, RT4, RPMI2650, MDA-MB-134-VI, NCI-H2347 and A427 cells.
    Concentration: 0-10 μM.
    Incubation Time: 72 hours.
    Result: Induced p53 signaling and inhibits tumor cell proliferation in three p53 wild-type tumor cell lines (SJSA-1, HCT116, and ACHN).
    Caused robust p21 mRNA induction between 9.76 and 34.9 fold with IC50 values ranging from 12.8 to 46.8 nM.
    In Vivo

    Navtemadlin (AMG 232) (10, 25, 75 mg/kg, once daily, p.o.) activates p53 pathway activity in vivo[1].
    Navtemadlin (10, 25, 75 mg/kg, once daily, p.o.) potently inhibits growth of tumor xenografts in mice[1].
    Navtemadlin (10, 25, 75 mg/kg, once daily, p.o.) blocks DNA synthesis and induces apoptosis in vivo[1].
    Navtemadlin causes a dose-dependent tumor growth inhibition with an ED50 of 16 mg/kg[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: Female athymic nude mice (n=10/group) based cancer models[1].
    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.
