Biological Activity

Description Danusertib (PHA-739358) is an Aurora kinase inhibitor for Aurora A/B/C with IC50 of 13 nM/79 nM/61 nM in cell-free assays, modestly potent to Abl, TrkA, c-RET and FGFR1, and less potent to Lck, VEGFR2/3, c-Kit, CDK2, etc. Danusertib induces apoptosis, cell cycle arrest, and autophagy. Phase 2.

In vitro Danusertib inhibits the activities of other kinases such as FGFR1, Abl, Ret and Trka, with IC50 of 47 nM, 25 nM, 31 nM and 31 nM, respectively. In a cell assay, after treatment of wild-type and p53-deficient MEFs with Danusertib, the wild-type cells undergo an arrest in mitosis (4N) that is maintained for up to 48 h. The p53-deficient cells on the other hand do not arrest at the 4N DNA stage, but continues with additional rounds of DNA synthesis to become >8N. Treatment with Danusertib results in an increase in p53 protein levels and an associated increase in p21 protein, which is known to be transcriptionally regulated by p53. [1] Increasing concentrations of Danusertib produces a dose-dependent reduction of cell growth after 48 hours in BCR-ABL-positive (K562, BV173) and BCR-ABL-negative (HL60) cells. [3]
In vivo Administration of 25 mg/kg Danusertib (b.d. i.v.) to HL-60 xenograft rats results in 75% inhibition of tumor growth with complete regression in one animal. Danusertib results in biomarker modulation accompanied by inhibition of tumor growth. This is compatible with an expected mechanism of action of aurora kinase inhibition. [1] Danusertib significantly inhibits proliferation of K562 cells and virtually suppressed tumor growth during the 10-day treatment period. [3]

Protocol (from reference)

Kinase Assay:[1]
  • Biochemical kinase Assays

    The Km values for ATP and the specific substrate are initially determined, and each assay is then run at optimized ATP (2Km) and substrate (5Km) concentrations. This setting enabled direct comparison of IC50 values of Danusertib across the applied kinase selectivity screening panel for the evaluation of the selectivity profile.

Cell Assay:[3]
  • Cell lines

    CD34+ cells

  • Concentrations

    5 μM

  • Incubation Time

    5 days

  • Method

    For short-term expansion assays, 1 × 103 CD34+ cells are plated in triplicates in 96-well plates containing 100 μL of serum-free medium per well supplemented with human stem-cell factor (100 ng/mL), human Flt-3 Ligand (100 ng/mL), human thrombopoietin (50 ng/mL), human interleukin-3 and -6 (IL-3 and IL-6, respectively, both 20 ng/mL), and granulocyte colony-stimulating factor (20 ng/mL) along with Danusertib at the indicated concentrations. After 5 days, an additional 100 μL of cytokine and Danusertib containing medium are added. Cell numbers within each individual well are estimated on days 3, 6, and 9 or on days 3, 6, and 12 for healthy donor samples.

Animal Study:[3]
  • Animal Models

    Female SCID mice

  • Dosages

    15 mg/kg

  • Administration

    Intraperitoneally
