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].
