生物活性 | Navtemadlin (AMG 232) is a potent, selective and orally available inhibitor ofp53-MDM2interaction, with anIC50of 0.6 nM. Navtemadlin binds toMDM2with aKdof 0.045 nM[1][2]. |
IC50& Target | IC50: 0.6 nM (p53-MDM2 interaction)[1] Kd: 0.045 nM (MDM2)[1] |
体外研究 (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].
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. |

体内研究 (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 ED50of 16 mg/kg[2].
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 ED50of 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. |
