Pharmacology
Filgrastim is a recombinant human G-CSF that binds to specific cell surface receptors on hematopoietic cells, stimulating neutrophil progenitor proliferation and differentiation and enhancing end-cell functional activities including phagocytic ability, respiratory burst priming, and antibody-dependent killing.
Quizartinib is a small molecule inhibitor of the receptor tyrosine kinase FLT3; it and its active metabolite AC886 bind the ATP binding domain of FLT3, inhibiting kinase activity and downstream FLT3 receptor signaling, thereby blocking FLT3-ITD-dependent cell proliferation.
