Selective FTO inhibitor (IC50 = 0.81 μM). Exhibits >30-fold selectivity for FTO over ALKBH2, 3 and 5 and >100-fold selectivity over PHD2 and JMJD2A. Increases levels of modified N6-methyladenosine (m6A) in HeLa cells in a concentration-dependent manner.
FTO-IN-8, also known as FTO-43, is an inhibitor of N6-methyladenosine demethylase FTO (fat mass- and obesity-associated protein). It exhibits an IC50 value of 5.5 μM and displays anti-cancer cell proliferative activity [1].
