Small molecule inhibition of METTL3 as a strategy against myeloid leukaemia.

The N6-methyladenosine (m6A) is an abundant internal RNA modification1,2 catalysed predominantly by the METTL3-METTL14 methyltransferase complex3,4. The m6A writer METTL3 has been linked to the initiation and maintenance of acute myeloid leukaemia (AML), but its true therapeutic importance is still unknown5-7. Here we present the identification and characterization of a highly potent and selective first-in-class catalytic inhibitor of METTL3 (STM2457) and its co-crystal structure bound to METTL3/METTL14. Treatment with STM2457 leads to reduced AML growth, and an increase in differentiation and apoptosis. These cellular effects are accompanied by selective reduction of m6A levels on known leukaemogenic mRNAs and a decrease in their expression consistent with a translational defect. We demonstrate that pharmacological inhibition of METTL3 in vivo leads to impaired engraftment and prolonged survival in various AML mouse models, specifically targeting key stem-cell subpopulations of AML. Collectively, these results reveal the inhibition of METTL3 as a potential therapeutic strategy against AML, and provide proof of concept that the targeting of RNA modifying enzymes represents a promising new avenue for anti-cancer therapy.
