30.0mg/ml Taking the 1 mL working solution as an example, add 300 μL of 100 mg/ml clarified PEG400 stock solution to 5 μL of Tween80, mix evenly to clarify it; add 50 μL Propylene glycol to the above system, mix evenly to clarify it; then continue to add 645 μL ddH2O to adjust the volume. to 1 mL. 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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Crenolanib is a potent and selective inhibitor of PDGFRα/β with Kd of 2.1 nM/3.2 nM in CHO cells, also potently inhibits FLT3, sensitive to D842V mutation not V561D mutation, >100-fold more selective for PDGFR than c-Kit, VEGFR-2, TIE-2, FGFR-2, EGFR, erbB2, and Src. Crenolanib helps to induce mitophagy.

In vitro

Crenolanib is significantly more potent in inhibiting the kinase activity of resistant PDGFRα kinases (D842I, D842V, D842Y, D1842-843IM, and deletion I843). Crenolanib is more potent against D842V in the isogenic model system, with an IC50 of approximately 10 nM. Crenolanib inhibits the kinase activity of the fusion oncogene in EOL-1 cell line, which is derived from a patient with chronic eosinophilic leukemia and expresses the constitutively activated FIP1L1- PDGFRα fusion kinase, with IC50 = 21 nM. Crenolanib also inhibits the proliferation of EOL-1 cells with IC50 = 0.2 pM. Crenolanib inhibits the activation of V561D or D842V-mutant kinases expressed in BaF3 cells with IC50 with 85 nM or 272 nM, respectively. Crenolanib inhibits PDGFRα activation in H1703 non-small cell lung cancer cell line which has 24-fold amplification of the 4q12 region that contains the PDGFRα locus, with IC50 with 26 nM. [1]

Crenolanib is an orally bioavailable, highly potent and selective PDGFR TKI. Crenolanib is a benzimidazole compound that has IC50s of 0.9 nM and 1.8 nM for PDGFRA and PDGFRB, respectively. [2]
In vivo

Crenolanib, a PDGFR inhibitor, suppresses lung cancer cell proliferation and inhibits tumor growth in vivo

Protocol (from reference)

Kinase Assay:

[1]
  • Biochemical Assessment of PDGFRα Kinase Activity

    Chinese hamster ovary (CHO) cells are transiently transfected with mutated or wild type PDGFRα constructs and treated with various concentrations of Crenolanib. Experiments involving recombinant DNA are performed using biosafety level 2 conditions in accordance with guidelines. Protein lysates from cell lines are prepared and subjected to immunoprecipitation using anti-PDGFRα antibodies followed by sequential immunoblotting for PDGFRα. Densitometry is performed to quantify drug effect using Photoshop software, with the level of phosphor- PDGFRα normalized to total protein. Densitometry and proliferation experimental results are analyzed using Calcusyn 2.1 software to mathematically determine the IC50 values. The Wilcoxon Rank Sum Test is used to compare the IC50 values of Crenolanib for a given mutation.

Cell Assay:

  • Cell lines

    EOL-1 cell line

  • Concentrations

    0-20 pM

  • Incubation Time

    72 hours

  • Method

    Cells are added to 96-well plates at densities of 20, 000 cells/well and incubated with Crenolanib for 72 hours before measuring cellular proliferation using a 2,3-bis[2-methoxyl-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide (XTT)-based assay.
