In U2OS cells, DDR1-IN-1 inhibits basal DDR1 autophosphorylation with EC50 of 86 nM, and demonstrates stronger inhibition of DDR1 autophosphorylation in the absence of collagen stimulation. In a panel of different cancer cell lines that possess DDR1 gain-of-function mutations and/or overexpression, DDR1-IN-1, dose not inhibit proliferation below a concentration of 10 μM, while GSK2126458 potentiates the antiproliferative activity of DDR1-IN-1.

Kinase Assay General procedure for the EC50 test
DDR1 is induced for 48 hrs prior to DDR1 activation by rat tail collagen I. The DDR1 over-expressed U2OS is pre-treated by media containing each concentration of the compound for 1 hr and treated by changing the media to the EC50 test media containing 10 Gg/ml collagen and each concentration of the compound for 2 hrs. Each cells is washed with cold PBS three times and lysed with the lysis buffer (50 mMTris, pH 7.5, 1% Triton X-100, 0.1% SDS, 150 mM NaCl, 5 mM EDTA, 100 mMNaF, 2 mM Na3VO4, 1 mM PMSF, and 10 Gg/ml leupeptin). The activation of DDR1 is quantified by density using program ImageJ to determine EC50 following Western blot using anti-activated human DDR1b (Y513).

Incubation Time 48 h
Method

Cells are plated in triplicate at a density of 3000 cells per well in 96-well plates and 1500 cells per well in 384-well plates. Compounds of various concentrations are added into plates for 48 hours. Cell viability is determined using the CellTiter-Glo and CCK-8. Both assays are performed according to the manufacturer’s instructions. For CellTiter-Glo assay, luminescence is determined in a multi-label reader. For CCK-8 assay, absorbance is measured in a microplate reader at 450nm. Data are normalized to control group (DMSO) and represented by the mean of at least two independent measurement with standard error <20%. GI50 were calculated using Prism 5.0.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
