Biological Activity

PHA-739358 (Danusertib) is a small molecule with low nanomolar activity against all aurora kinases (AKs) with IC50 value of 13 nM for aurora-A and 79 nM for aurora-B respectively. PHA-739358 (Danusertib) also inhibits other cancer relevant tyrosine kinases such as wild type and mutated ABL, RET, TRK-A and FGFRs.

Method MTT assay
Cell Lines Ba/F3 cells
Concentrations 200 nM
Incubation Time 48 h
Results Accordingly, IC50 values were in a range of 150 nM for PHA-739358 and 10 nM for R763/AS703569, independent of the BCR-ABL mutation status
Cell Experiment
Cell lines wild-type (HCT-116 cells )or p53 −/− MEF (A2780) cells
Preparation method Analysis of Cell Proliferation Analysis was done as previously described (20). Briefly, cells were seeded at different densities in 24-well plates with the appropriate medium. After 24 h, cells were treated with compound and incubated for 72 h at 37°C in 5% CO2 atmosphere. At the end of the incubation time, cells were detached from each plate and counted using a cell counter (Coulter Counter-Beckman). IC50 values were calculated using percent of growth versus untreated control.

Incubation time 24 or 48 hr
Animal Experiment
Animal models Mice bearing established A2780 and HCT-116 tumor xenografts
Formulation saline
Dosages 30 mg/kg bd for 5 consecutive days
Administration i.v.
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
