Description

FB23 is a potent and selective FTO demethylase inhibitor with an IC50 of 60 nM. FB23 directly binds to FTO and selectively inhibits FTO's mRNA N6-methyladenosine (m6A) demethylase activity[1].

IC50 & Target

IC50: 60 nM (FTO)[1]
In Vitro

FB23 (72 hours) treatment inhibits acute myeloid leukemia (AML) cells proliferation with IC50 values of 44.8 μM, 23.6 μM for NB4 and MONOMAC6 AML cells[1].
FB23 treatment causes the significant suppression of MYC targets, E2F targets, and G2M checkpoint signal cascades, which may contribute to the inhibitory effects of FTO inhibitors and FTO KD on cell cycle and proliferation. FB23 treatments activates apoptosis and p53 pathways[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.
