[In Vitro]

DDR1-IN-2 (compound 1) is a potent inhibitor of DDR1, with an IC50 of 13.1 nM, and less potently inhibits DDR2, with an IC50 of 203 nM. DDR1-IN-2 also shows inhibitory activities against Bcr-Abl and c-Kit, with IC50s of 414 and 2500 nM, respectively[1].

[Kinase Assay]

The effects of compounds (including DDR1-IN-2) on the kinases DDR1 and DDR2 are assessed by using a LanthaScreen Eu kinase activity assay technology. Kinase reactions are performed in a 10 µL solution in low-volume 384-well plates. The kinase reaction buffer consists of 50 mM HEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, and 1 mM EGTA; the concentration of Fluorescein-Poly GAT substrate in the assay is 100 nM. Kinase reactions are initiated by the addition of 100 nM ATP in the presence of serially diluted compounds (DDR1-IN-2). The reactions are allowed to proceed for 1 h at room temperature before a 10 µL preparation of EDTA (20 mM) and Eu-labeled antibody (4 nM) in TR-FRET dilution buffer are added. The final concentration of antibody in the assay well is 2 nM, and the final concentration of EDTA is 10 mM. The plate is allowed to incubate at room temperature for one more hour before the TR-FRET emission ratios of 665 nm/340 nm are acquired on a multilabel reader. Data analysis and curve fitting are performed using GraphPad Prism4 software[1].
