Taking the 1 mL working solution as an example, add 80 μL of 93.75 mg/ml clear DMSO stock solution to 920 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Biological Activity

Description

DDR1-IN-1 is a potent and selective discoidin domain receptor 1 (DDR1) receptor tyrosine kinase inhibitor with IC50 of 105 nM, about 3-fold selectivity over DDR2.

Targets

DDR1 ^[1] (Cell-free assay)	DDR2 ^[1] (Cell-free assay)
105 nM	413 nM

In vitro

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. ^[1]

Protocol (from reference)

Kinase Assay:^{^[1]}	General procedure for the EC50 test DDR1 is induced by 2 Gg/ml doxycycline 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, 10 Gg/ml aprotinin, 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).
Cell Assay:^{^[1]}	Cell lines U2OSWT, U2OSOWT and U2OSG707A cell lines Concentrations ~20 μM 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.
