Crenolanib

DescriptionCrenolanib (670220-88-9) is a potent inhibitor of PDGFR (Kdfor α = 2.1 nM; β = 3.2 nM) and FLT3 (Kd= 0.74 nM).1Crenolanib is a type I inhibitor binding only to the active kinase conformation. It showed potent activity against imatinib-resistant PDGFRα mutations D842I, D842V, D842Y, DI842-843M, and deletion I8432as well as FLT3/ITD and FLT3/D835 mutants3. Crenolanib acted synergistically with FLT3-CAR T-cells in a FLT3-ITD+AML murine xenograft model.4

UsesCrenolanib (CP-868569) is a highly selective and potent PDGFR-α inhibitor with IC50 of 0.9 and 1.8 nM against PDGFRα and PDGFRβ, respectively.

UsesCrenolanib (CP-868569) is a tyrosine kinase inhibitor that acts by specifically inhibiting the receptor tyrosine kinases PDGFRα and PDGFRβ. Crenolanib (CP-868569) inhibits the activity of PDGFRα D842V kinase and prevented the phosphorylation of wild type PDGFRα. Crenolanib (CP-868569) possesses potential antineoplastic activity. Crenolanib is believed to suppress PDGFR-related signal transduction pathways leading to the inhibition of tumor angiogenesis and tumor cell proliferation.

UsesCrenolanib is an orally bioavailable, selective inhibitor of type III tyrosine kinases with nanomolar potencies against platelet-derived growth factor receptor α (PDGFRα) and PDGFRβ and Fms-related tyrosine kinase 3 (FLT3; IC50s = 11, 3.2, and 4 nM, respectively). It also inhibits medically-relevant mutant forms of these kinases, including the D842V-containing form of PDGFR and D835Y and internal tandem duplication mutations of FLT3, at nanomolar concentrations. Crenolanib is more than 100-fold selective for these kinases over other tyrosine and serine/threonine kinases. It is effective when used in cells and in vivo.[Cayman Chemical]
