Biological Activity

Description

FB23-2 is a potent and selective FTO inhibitor that directly binds to FTO and selectively inhibits FTO's N⁶-methyladenosine (m⁶A) demethylase activity with IC50 of 2.6 μM.

Targets

FTO ^[1]
(Cell-free assay)

2.6 μM

In vitro
In vitro	FB23-2 directly binds to FTO and selectively inhibits FTO’s m⁶A demethylase activity. Mimicking FTO depletion, FB23-2 dramatically suppresses proliferation and promotes the differentiation/apoptosis of human acute myeloid leukemia (AML) cell line cells and primary blast AML cells in vitro.^[1]
Cell Research	Cell lines	Leukemia cells NB4, U937, MV4-11, ML-2; MONOMAC6 (ACC-124) cells; 293T cells; The mouse bone marrow cells FLT3ITD/NPM1, MA9
	Concentrations	10 μM, 5 μM
	Incubation Time	24 h, 72 h
	Method	NB4 and MONOMAC6 cells are treated with DMSO or FB23-2 at varying concentrations for 72 h, while MA9 and FLT3/NPM1 primary cells isolated from AML mice, five human AML cell (MA9.3ITD, MA9.3RAS, U937, ML2, and MV4-11), and human primary AML cells are treated with DMSO or 5 μM FB23-2 for 72 h for dot blot assay.

In Vivo
In vivo	FB23-2 significantly inhibits the progression of human AML cell lines and primary cells in xeno-transplanted mice.^[1]
Animal Research	Animal Models	NSGS mice with xeno-transplantation model
	Dosages	2 mg/kg
	Administration	IP

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
