    Description

    Crenolanib is a potent and selective inhibitor of wild-type and mutant isoforms of the class III receptor tyrosine kinases FLT3 and PDGFRα/β with Kds of 0.74 nM and 2.1 nM/3.2 nM, respectively.

    IC50 & Target[1]

    PDGFRα

    2.1 nM (Kd)

    PDGFRβ

    3.2 nM (Kd)

    FLT3

    0.74 nM (Kd)

    In Vitro

    Crenolanib has 25-fold more affinity for PDGFRA/B compared with KIT, and is approximately 135-fold more potent than STI571 for inhibiting the PDGFRA D842V mutation. The IC50 for crenolanib for a KIT exon 11 deletion mutant kinase is greater than 1,000 versus 8 nM for STI571. Crenolanib has low nanomolar potency against the V561D + D842V-mutant kinase that is similar to its potency against the isolated D842V mutation. Both STI571 and crenolanib potently inhibit the kinase activity of the fusion oncogene with IC50 values of 1 and 21 nM, respectively, and inhibits PDGFRA activation in this cell line with IC50 values of 93 and 26 nM, respectively[1]. HL60/VCR and K562/ABCB1 cells, overexpressing ABCB1, are 6.9- and 3.6-fold resistant to crenolanib, respectively, in relation to parental HL60 and K562 cells. PSC-833 fully reverses resistance to crenolanib in both HL60/VCR and K562/ABCB1 cells. Crenolanib (1 nM-10 μM) stimulates ABCB1 ATPase activity in a concentration-dependent manner. Crenolanib treatment does not increase the cell surface expression of ABCB1. Crenolanib inhibits [125I]-IAAP photocrosslinking of ABCB1 at high concentrations, with 50 % inhibition at 10 μM, but has little effect at lower concentrations, below 1 μM[2]. Crenolanib decreases NSCLC cell viability, induces apoptosis in NSCLC cells, and inhibits cell migration in NSCLC cells[3].

    In Vivo

    Crenolanib (10 mg/kg and 20 mg/kg) suppresses non-small-cell lung cancer tumor growth in vivo and induces tumor cell apoptosis, and the dosage of crenolanib applied is well tolerated by recipient mice[3].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    90% Corn Oil

      Solubility: ≥ 3 mg/mL (6.76 mM); Clear solution

      This protocol yields a clear solution of ≥ 3 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (30.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    • Protocol 2

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 1.43 mg/mL (3.22 mM); Clear solution

      This protocol yields a clear solution of ≥ 1.43 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

    Cell Assay
    [2]

    Viable cell numbers following drug treatment are measured using the WST-1 assay. Briefly, 1×103 cells are seeded in 100 μL complete medium per well in 96-well tissue culture plates and incubated with crenolanib (0-10 μM) at 37°C in 5% CO2 for 96 h. 10 μL WST-1 reagent is then added to each well, incubation is continued for two additional hours and the color developed is quantified according to the manufacturer’s instructions. Each experiment is performed in triplicate. IC50 concentrations are calculated by the least square fit of dose–response inhibition in a non-linear regression model using GraphPad Prism V software.

    Animal Administration
    [3]

    A549 cells are injected into the axillary regions of mice (2×106 cells/mouse). When the tumor volumes reached 70 mm3, the mice are randomLy allocated to the control group, low-dose crenolanib group (10 mg/kg), or high-dose crenolanib group (20 mg/kg) (n=6 per group). The vehicle for crenolanib treatment consists of 10% 1-methyl-2-pyrrolidinone and 90% polyethylene glycol 300. The tumor size and mouse body weight are measured every other day for about 2 weeks. The tumor volume is calculated as follows: (mm3)=(width×width×length)/2. After treatment, the mice are euthanized using carbon dioxide, and the tumors are harvested and analyzed.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
