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.
|Source||PLoS One (2014). Figure 1. PHA-739358|
|Cell Lines||Ba/F3 cells|
|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 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 models||Mice bearing established A2780 and HCT-116 tumor xenografts|
|Dosages||30 mg/kg bd for 5 consecutive days|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
|Solubility||DMSO ≥95 mg/mL|
