This PDF file includes:

  • Materials and Methods
  • Fig. S1. MDMX is overexpressed in cancers of hematopoietic and lymphoid origin.
  • Fig. S2. MS2-SL repeats were inserted into a single allele of the p21 gene.
  • Fig. S3. ALRN-6924 disrupts the p53-MDM2 and p53-MDMX protein-protein interactions and activates p53-dependent pathways.
  • Fig. S4. MDMX-FL is differentially expressed in p53 WT AML cell lines sensitive to ALRN-6924.
  • Fig. S5. In vivo xenograft models of leukemia development are sensitive to ALRN-6924.
  • Fig. S6. Peripheral blood leukemic blasts from an MDS/AML patient treated with ALRN-6924 were analyzed by flow cytometry.
  • Table S1. ALRN-6924 binding kinetics to MDMX and MDM2 compared to RG7388, a small-molecule MDM2 inhibitor.
  • Table S2. Sensitivity of leukemia cell lines expressing WT and mutant p53 to ALRN-6924.
