MD-224, CAS No. 2136247-12-4, is a First-in-Class, Highly Potent, and Efficacious Proteolysis Targeting Chimera Murine Double Minute 2 Degrader Capable of Achieving Complete and Durable Tumor Regression. MD-224 effectively induces rapid degradation of MDM2 at concentrations <1 nM in human leukemia cells. It achieves an IC50 value of 1.5 nM in inhibition of growth of RS4;11 cells and also low nanomolar IC50 values in a panel of leukemia cell lines. MD-224 achieves complete and durable tumor regression in vivo in the RS4;11 xenograft tumor model in mice at well-tolerated dose schedules. MD-224 is thus a highly potent and efficacious MDM2 degrader and warrants extensive evaluations as a new class of anticancer agent.

How to use

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.
