Gilteritinib (ASP2215) is a small-molecule inhibitor of FLT3/AXL with IC50 values of 0.29 nM and 0.73 nM for FLT3 and AXL, respectively. Gilteritinib (ASP2215) is a highly selective FLT3 inhibitor that demonstrates activity against both FLT3-ITD and FLT3-TKD mutation subtypes and selectively inhibits FLT3 at concentrations roughly 800-fold lower than those required to inhibit c-Kit (230 nM). This product is a pre-formulated liposomal version of Gilteritinib (ASP2215) which is supplied ready to use in vitro or in vivo. The liposomes are PEGylated for optimal in vivo performance; the lipid composition of the liposomes is the same as Doxil. For preclinical research use only.
