Biochem/physiol Actions

FB23-2 can also prevent osteogenic differentiation of human mesenchymal stem cells (MSCs). It is capable of delaying leukemogenesis in vivo. In mice, FB23-2 at a dose of 20 mg/kg is safe for testing in vivo efficacy.
FB23-2 is a cell penetrant, potent and specific inhibitor of N6-methyladenosine (m6A) demethylase FTO (fat mass and obesity associated protein) that RNA methylation in varies of AML cells. FB23-2 potently inhibits proliferation and promotes apoptosis and differentiation in human acute myeloid leukemia (AML) cells and primary blast AML cells lines and xenografts in mice. It minimally affects proliferation of human normal bone marrow cells.

FTO, an mRNA N6-methyladenosine (m6A) demethylase, was reported to promote leukemogenesis. Using structure-based rational design, we have developed two promising FTO inhibitors, namely FB23 and FB23-2, which directly bind to FTO and selectively inhibit FTO's m6A demethylase activity. Mimicking FTO

N6-methyladenosine (m6A) is the most abundant posttranscriptional methylation modification that occurs in mRNA and modulates the fine-tuning of various biological processes in mammalian development and human diseases. In this study we investigated the role of m6A modification in the osteogenesis
