Biological Activity

PF-562271 is a potent, ATP-competitive, reversible inhibitor of FAK and Pyk2 with IC50 of 1.5 nM and 14 nM, respectively. Treatment with PF-562271 impaires cell viability in all cell lines, with an average IC50 of 2.4 μM after 3 days of treatment. TC32 and A673 are the 2 most sensitive cell lines, with IC50 concentrations of 2.1 and 1.7 μM, respectively. 

In vivo, Rats received PF-562271 demonstrate a decrease in tumor growth after 2 weeks of treatment with signs of bone healing as evidenced by the deposition of new bone (cortical and cancellous) at sites previously damaged by the tumor.

Cell Experiment
Cell lines MPanc-96 or MAD08-608 cells
Preparation method Cell migration and invasion assays were performed using transwell migration chambers (BD Biosciences, Bedford, MA) as previously described (26–28). Conditioned media was prepared from subconfluent MPanc-96 or MAD08-608 cells by harvesting growth medium (containing 0.5% FBS) for two 24 h periods. The conditioned media was centrifuged to remove cellular debris and concentrated 3 fold using Amicon Ultra-15 3K centrifugal filter devices (Millipore, Billerica, MA). Mock conditioned media was prepared by concentrating 0.5% FBS in similar fashion. For proliferation assays, cells (1.5 × 105) were plated in 96-well plates in 1% FBS-containing media and cell number was measured using the CyQuant assay (Invitrogen, Grand Island, NY).

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.
