Biological Activity

Description MI-773 (SAR405838) is an orally available MDM2 antagonist with Ki of 0.88 nM. Phase 1.
Targets
MDM2 [1]
(Cell-free assay)		 MDM2 [1]
0.88 nM(Ki) 8.2 nM(Kd)
In vitro MI-773 binds to MDM2 with Ki of 0.88 nM. MI-773 potently inhibits cell growth in cancer cell lines, including SJSA-1 (IC50, 0.092 μM), RS4;11 (IC50, 0.089 μM), LNCaP (IC50, 0.27 μM), and HCT-116 (IC50, 0.20 μM) cells, and displays high selectivity over cancer cell lines with mutated or deleted p53, including SAOS-2 (IC50, >10 μM), PC-3 (IC50, >10 μM), SW620 (IC50, >10 μM), and HCT-116 (p53-/-) (IC50, >20 μM) cells. [1]
In vivo In the SJSA-1 osteosarcoma, acute lymphoblastic leukemia RS4;11, LNCaP prostate cancer, and HCT-116 colon cancer xenograft model, MI-773 (p.o.) effectively inhibits tumor growth in a dose-dependent manner (10 mg/kg, 30 mg/kg, 50 mg/kg, 100 mg/kg, and 200 mg/kg,). [1]

Protocol (from reference)

Kinase Assay:[1]
  • Fluorescence-polarization binding assay

    Binding affinities of MDM2 inhibitors and p53 peptide to MDM2 protein are determined using an Fluorescence-polarization (FP) binding assay. Binding affinities of MI-773 to Bcl-2, Bcl-xL, Mcl-1, and β-catenin are determined using a competitive FP-based assay, and its binding affinity to MDMx is determined using Biolayer Interferometry technology.
Cell Assay:[1]
  • Cell lines

    SJSA-1, RS4;11, LNCaP, SAOS-2, PC-3, SW620, HCT-116, and HCT-116 (p53-/-) cells

  • Concentrations

    100 μM

  • Incubation Time

    ~48 h

  • Method

    Cell growth inhibition activity is determined in a water-soluble tetrazolium-based assay. Cell death is measured by trypan blue staining and apoptosis is determined using an Annexin V-FLUOS staining kit.
Animal Study: [1]
  • Animal Models

    SCID mice with SJSA-1 osteosarcoma (females), acute lymphoblastic leukemia RS4;11 (females), LNCaP prostate cancer (males), or HCT-116 colon cancer (females) xenograft model

  • Dosages

    200 mg/kg

  • Administration

    p.o.
