Quizartinib is an anticancer chemotherapeutic compound that inhibits FMS-like tyrosine kinase 3 (FLT3), c-Kit, and PDGFR. Quizartinib is clinically used to treat acute myelogenous leukemia. In cellular models, quizartinib induces apoptosis and inhibits proliferation. This compound also inhibits ATP-binding cassette ABCG2, also known as breast cancer resistance protein. Quizartinib is supplied as a crystalline solid. Quizartinib is soluble in DMSO to 33 mg/mL, in water to <0.3 mg/ml, and in ethanol to <0.5 mg/ml. If Quizartinib needs to be stored long term, we recommend storing the solid Quizartinib and not storing the Quizartinib in solution due to potential loss of stability.
