Biological Activity
TPKI-39 (1 μM; dose-response) potently engages DDR1, DDR2, and FLT1 in live HEK293 cells, with minimal to no engagement of most kinases identified as high-affinity binders in cell-free assays, and uniquely engages DDR2 in cells but not in cell-free systems[1].
TPKI-39 (0.313-5 μM; 1 h pretreatment, 24 h cotreatment with collagen I) potently inhibits DDR1 signaling (autophosphorylation) in HeLa cells stimulated with collagen I[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:HeLa cells (transiently transfected with DDR1b-encoding cDNA)
-
Concentration:0.313-5 μM (pretreated; cotreated with collagen I)
-
Incubation Time:1 h (pretreatment); 24 h (cotreatment with collagen I)
-
Result:Dose-dependently inhibited collagen-induced DDR1 autophosphorylation.
Reduced phosphorylation to basal levels (observed without collagen activation) at concentrations ≥1.25 μM, comparable to the established DDR1 inhibitor DDR1-IN-1.
