In Vitro

FLT3-IN-12 (compound 36) efficiently inhibits the growth of multiple mutant BaF3 cells expressing FLT3-ITD, FLT3-D835V/F, FLT3-F691L, FLT3-ITD-F691L, and FLT3-ITD-D835Y with the IC₅₀ range is 0.16-14.5 nM^[1].

In Vivo

Oral administration of FLT3-IN-12 (compound 36) at 6 mg/kg/d could significantly suppress tumor growth in the MV4-11 cell-inoculated xenograft model, exhibiting a tumor growth inhibitory rate of 95.1%. Importantly, FLT3-IN-12 could prolong the mouse survival time in the FLT3-ITD-TKD dual mutation syngeneic mouse model (BaF3-FLT3-ITD-D835Y) at a dose of 6 mg/kg p.o. bid/4W^[1].
FLT3-IN-12 (compound 36; 20 mg/kg; oral administration) exhibits excellent plasma exposure (area under the curve (AUC)_0–∞ of 5278 ng·h/mL), T_1/2 of 3.7 hours, and high maximum plasma concentrations (C_max of 775 ng/mL)^[1].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
