For example, the ethyl ester form of Meclofenamic acid (MA) MA2, a US Food and Drug Administration (FDA)-approved nonsteroidal anti-inflammatory drug, was found to be a FTO inhibitor which led to elevated levels of m6A modification in mRNAs in glioblastoma cells, suppressing tumour progression and prolonging the lifespan of GSC-grafted mice [35, 150]. Here, FTO is linked to neoplasm.
