== Disease ==
[https://www.uniprot.org/uniprot/FTO_HUMAN FTO_HUMAN] Defects in FTO are the cause of growth retardation developmental delay coarse facies and early death (GDFD) [MIM:[https://omim.org/entry/612938 612938]. A severe polymalformation syndrome characterized by postnatal growth retardation, microcephaly, severe psychomotor delay, functional brain deficits and characteristic facial dysmorphism. In some patients, structural brain malformations, cardiac defects, genital anomalies, and cleft palate are observed. Early death occurs by the age of 3 years.<ref>PMID:19559399</ref> 
== Function ==
[https://www.uniprot.org/uniprot/FTO_HUMAN FTO_HUMAN] Dioxygenase that repairs alkylated DNA and RNA by oxidative demethylation. Has highest activity towards single-stranded RNA containing 3-methyluracil, followed by single-stranded DNA containing 3-methylthymine. Has low demethylase activity towards single-stranded DNA containing 1-methyladenine or 3-methylcytosine. Has no activity towards 1-methylguanine. Has no detectable activity towards double-stranded DNA. Requires molecular oxygen, alpha-ketoglutarate and iron. Contributes to the regulation of the global metabolic rate, energy expenditure and energy homeostasis. Contributes to the regulation of body size and body fat accumulation.<ref>PMID:18775698</ref> <ref>PMID:20376003</ref>

== Publication Abstract from PubMed ==
Fat mass and obesity-associated protein (FTO) is the first discovered RNA N(6)-methyladenosine (m(6)A) demethylase. The highly expressed FTO protein is required to trigger oncogenic pathways in acute myeloid leukemia (AML), which makes FTO a promising antileukemia drug target. In this study, we identify 3-arylaminothiophenic-2-carboxylic acid derivatives as new FTO inhibitors with good antileukemia activity. We replaced the phenyl A-ring in FB23, the first-generation of FTO inhibitor, with five-membered heterocycles and synthesized a new class of FTO inhibitors. Compound 12o/F97 shows strong enzymatic inhibitory activity and potent antiproliferative activity. 12o/F97 selectively inhibits m(6)A demethylation by FTO rather than ALKBH5, and has minimal effect on m(1)A demethylation by ALKBH3. Additionally, 12o/F97 increases the protein levels of RARA and ASB2, while decreasing that of MYC in AML cell lines. Lastly, 12o/F97 exhibits antileukemia activity in a xenograft mice model without significant side-effects. The identification of 3-arylaminothiophenic-2-carboxylic acid derivatives as new FTO inhibitors not only expands the chemical space but also holds potential for antileukemia drug development.
