Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.9mg/ml Taking the 1 mL working solution as an example, add 50 μL of 38 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

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

FB23 treatment inhibits acute myeloid leukemia (AML) cells proliferation with IC50 values of 44.8 μM, 23.6 μM for NB4 and MONOMAC6 AML cells. 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]
In vivo

Pharmacological inhibition of FTO by FB23-2 substantially suppresses leukemia progression and prolongs survival.[1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    AML cell lines

  • Concentrations

    1-50 μM

  • Incubation Time

    24 h, 48 h, 72 h, 96 h

  • Method

    AML cells are seeded and treated with DMSO or FB23 for 24 h, 48 h, 72 h, or 96 h. The cell proliferations are determined with CellTiter 96® AQueous Non-Radioactive Cell Proliferation Assay. AML cells are treated with DMSO or 5 μM FB23-2 for 72 hr for dot blot assay.
