Milademetan (DS-3032) tosylate hydrate is a specific and orally active MDM2 inhibitor for the research of acute myeloid leukemia (AML) or solid tumors. Milademetan (DS-3032) tosylate hydrate induces G1 cell cycle arrest, senescence and apoptosis[1][2].
Milademetan (DS-3032) can stabilize TP53 and selectively induce CDKNA1, BAX and MDM2 expression in neuroblastoma cells with wild-type TP53[3].Milademetan (DS-3032b) treatment enhances TP53 target gene expression and induces G1 cell cycle arrest, senescence and apoptosis[3].Milademetan (DS-3032b, 0-2000 nM) treatment selectively inhibits viability, proliferation and migration of neuroblastoma cells with wildtype TP53 independently of MYCN status[4].
Milademetan (DS-3032b, 50 mg/kg, oral gavage) delays tumor growth and improves survival in mice xenografted with neuroblastoma cells with functional TP53[4].
