Western blot analysis using 4G10 and anti-FLT3 antibody after immunoprecipitation with anti-FLT3 antibody and Western blot analysis of phospho-ERK (pERK) and ERK performed on whole cell lysates from HB119 and Molm14 cells. Cells were exposed to 100 nM crenolanib for 60 min.

Concurrent treatment with Crenolanib and AG1478 enhances apoptosis as monitored by Caspase-3 and PARP-1 cleavage, either in GBM c-CSC or p-CSC, except for p-CSC3. Instead, Crenolanib alone is less effective in inducing apoptosis either in c-CSC or p-CSC pools. High PDGFR α expression is a distinctive feature of p-CSC pools and its expression is de-repressed following AG1478 treatment clearly evident in case 1 and 2, while its expression is downmodulated following Crenolanib treatment in all cases reported.

Combined treatment with Pim and FLT3 inhibitors abrogates growth of Ba/F3-ITD cells. Ba/F3-ITD cells were cultured at 1 × 105/mL with the Pim kinase inhibitor AZD1208 at 1 μmol/L and/or the FLT3 inhibitors quizartinib at 1 nmol/L, sorafenib at 2.5 nmol/L, crenolanib at 20 nmol/L or gilteritinib at 15 nmol/L, or DMSO control. Cell counts measured at 24, 48, and 72 hours were normalized to 0-hour control. Line graphs represent means ± SEM of triplicate values.

NSG mice were inoculated with 1x106 MOLM-13 cells (ffluc+GFP+662 ) and on day 7 were treated with 5x106 FLT3-CAR T-cells alone (CD4+:CD8+ ratio = 1:1), crenolanib alone (15mg/kg body weight as i.p. injection), or both (combination), or were left untreated. The first dose of crenolanib was given on day 7 and mice received 15 doses (Monday-Friday) for 3 consecutive weeks.

|Description||Crenolanib (CP-868596) 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 is significantly more potent than imatinib in inhibiting the kinase activity of imatinib-resistant PDGFRα kinases (D842I, D842V, D842Y, D1842-843IM, and deletion I843). Crenolanib is 135-fold more otent than imatinib 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.  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. 
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.

* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
