Protein methyltransferases (PMTs) participate in the epigenetic control of cell fate and other signaling pathways that are deregulated in disease, and the first PMT inhibitors have entered clinical trials in oncology. This review discusses structural studies that recently uncovered the mode of action of compounds in the clinic, as well as challenges and opportunities in the development of PMT inhibitors. It examines inhibitors that compete with the highly polar cofactor but preserve cell penetrance, and allosteric modes of inhibition. Vectors of optimization at the substrate-binding site and the potential of fragment screening approaches are discussed. Finally, the review presents strategies focused on targeting non-catalytic domains of PMTs or scaffolding subunits of chromatin complexes. Overall, although targeting PMTs remains a challenge, recent successes in the field are diverse and encouraging.
