MD-224

MD-224 is a first-in-class and highly potent small-molecule human murine double minute 2 ( MDM2 ) degrader based on the proteolysistargeting chimera (PROTAC) concept. MD-224 consists of ligands for Cereblon and MDM2 . MD-224 induces rapid degradation of MDM2 at concentrations In Vitro MD-224 (1-30 nM; 2 hours) effectively induces depletion of MDM2 protein and concurrently accumulation of p53 protein in a dose-dependent manner in RS4;11 cells. MD-224 (30 nM; 6 hours) is more potent than MI-1061 in induction of transcriptional upregulation of these p53 target genes but have no effect on TP53 itself in RS4;11 cells. MD-224 (0.001-1 μM; 24 hours) induces robust apoptosis at ≤10 nM in a dose-dependent manner upon a 24 hours treatment. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
