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. |

Las células de ovario de hámster chino (CHO) se transfectan transitoriamente con constructos PDGFRα mutados o de tipo salvaje y se tratan con diversas concentraciones de Crenolanib. Los experimentos que involucran ADN recombinante se realizan utilizando condiciones de nivel de bioseguridad 2 de acuerdo con las directrices. Los lisados de proteínas de las líneas celulares se preparan y se someten a inmunoprecipitación utilizando anticuerpos anti-PDGFRα seguidos de inmunotransferencia secuencial para PDGFRα. La densitometría se realiza para cuantificar el efecto del fármaco utilizando el software Photoshop, con el nivel de fosfor-PDGFRα normalizado a la proteína total. Los resultados experimentales de densitometría y proliferación se analizan utilizando el software Calcusyn 2.1 para determinar matemáticamente los valores de IC50. La prueba de suma de rangos de Wilcoxon se utiliza para comparar los valores de IC50 de este compuesto para una mutación dada.
