IC50: 3.3 nM (DDR2)[1] IC53: 1.5 nM (DDR1)[1]

DDR Inhibitor (Example 6) is a potent DDR inhibitor, with an IC50 of 3.3 nM for DDR2, and shows 53% inhibition on DDR1 at 1.5 nM[1].

Europium Kinase binding assay is used. Compounds (DDR Inhibitor, etc.) are incubated with 0.5 nM DDR1 or 0.25 nM DDR2 for 1 hour at room temperature in low volume black 384 well assay plates containing 5 nM or 10 nM Kinase Tracer 178 respectively and 2 nM Europium labelled anti-GST antibody in assay buffer (50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM EGTA and 0.01 % BRIJ35). The ratio of fluorescence emission 665 nm/615 nm after excitation at 340 nm is obtained. IC50 values are determined from dose-response plots using nonlinear least-squares analysis[1].
