Mechanism of Action

Targets/IC₅₀/Ki	FLT3 (CHO cells) 0.74 nM(Kd) PDGFRα (CHO cells) 2.1 nM(Kd) PDGFRβ (CHO cells) 3.2 nM(Kd)
In vitro	Crenolanib is significantly more potent in inhibiting the kinase activity of resistant PDGFRα kinases (D842I, D842V, D842Y, D1842-843IM, and deletion I843). This compound is more potent against D842V in the isogenic model system, with an IC50 of approximately 10 nM. It 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. This chemical also inhibits the proliferation of EOL-1 cells with IC50 = 0.2 pM. It inhibits the activation of V561D or D842V-mutant kinases expressed in BaF3 cells with IC50 with 85 nM or 272 nM, respectively. This compound 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. It is an orally bioavailable, highly potent and selective PDGFR TKI. This benzimidazole compound has IC50s of 0.9 nM and 1.8 nM for PDGFRA and PDGFRB, respectively.
Kinase Assay	Biochemical Assessment of PDGFRα Kinase Activity
Kinase Assay	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 analysed using Calcusyn 2.1 software to mathematically determine the IC50 values. The Wilcoxon Rank Sum Test is used to compare the IC50 values of this compound for a given mutation.
In vivo	This compound, a PDGFR inhibitor, suppresses lung cancer cell proliferation and inhibits tumour growth in vivo
