FB23-2

Research use only, not for human use.

FB23-2 is a potent, selective inhibitor of the mRNA N 6-methyladenosine (m 6A) demethylase FTO.

FB23-2 is a potent, selective inhibitor of the mRNA N 6-methyladenosine (m 6A) demethylase FTO, directly bind to FTO, inhibits FTO demethylation of m6 A in RNA in vitro with IC50 of 2.6 uM; demonstrates significantly improved anti-proliferative activity on NB4 and MONOMAC6 cells with IC50 of 0.8-1.5 uM, compared with parental compound FB23; dramatically suppresses proliferation and promotes the differentiation/apoptosis of human acute myeloid leukemia (AML) cell line cells and primary blast AML cells in vitro; FB23-2 significantly inhibits the progression of human AML cell lines and primary cells in xeno-transplanted mice.

Cell Proliferation Assay Cell Line:MA9 cells, FLT3ITD/NPM1 cells (mouse BM cells)Concentration:0.5 μM, 2 μM, 5 μMIncubation Time:24 hours, 48 hours, 72 hours Result:Suppressed the proliferation of BM cells.RT-PCRCell Line:NB4 cells, MONOMAC6 cells Concentration:1 μM, 5 μM , 20 μM Incubation Time:72 hours Result:Significantly increased ASB2 and RARA mRNA levels.Apoptosis Analysis Cell Line:NB4 cells, MONOMAC6 cells Concentration:1 μM, 5 μM , 20 μM Incubation Time:48 hours (NB4 cells),72 hours (MONOMAC6 cells)Result:Induced apoptosis.Cell Cycle Analysis Cell Line:MONOMAC6 cells Concentration:5 μM , 20 μM Incubation Time:24 hours Result:Induced cell cycle arrest at G1 stage.

Animal Model:NOD/LtSz-scid IL2RG-SGM3 (NSGS) mice, xeno-transplanted with MONOMAC6 AML cells Dosage:2 mg/kg Administration:Intraperitoneal injection, daily, for 10 days Result:Delayed the onset of full-blown leukemic symptoms and significantly prolonged survival by almost doubling the median survival.Animal Model:Sprague Dawley (SD) rats Dosage:3 mg/kg (Pharmacokinetic Analysis)Administration:Intraperitoneal injection Result:T1/2 (6.7 hours), Cmax (2421.3 ng/mL).
