Description

FLT3-IN-18 is a potent and selective FLT3 inhibitor with an IC50 value of 0.003 μM. FLT3-IN-18 induces apoptosis and cell cycle arrest at G1 phase. FLT3-IN-18 inhibits FLT3 and STAT5 phosphorylation. FLT3-IN-18 has the potential for the research of acute myeloid leukemia (AML)[1].

IC50 & Target

IC50: 0.003 µM (FLT3)[1]

In Vitro

FLT3-IN-18 (compound 7d) (0, 0.01, 0.1, 1, 10, 100 nM; 1h) decreases the protein expression of p-FLT3 Y589/591, p-FLT3 Y842, p-TAT5 Y694, p-ERK1/2 T202/Y204, and p-MEK1/2 S217/221, p-AKT S473 in a dose-dependent manner in MV4-11 cells[1].
FLT3-IN-18 (0, 0.01, 0.1, 1, 10, 100 nM; 24 h) induces apoptosis and cell cycle arrest at G1 phase[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.
