In this study, a deconstruction-reconstruction approach was used to identify potent and selective inhibitors of PRMT4. These inhibitors demonstrated a reduction in arginine methylation levels and proliferation in MCF7 cells, despite their low cell permeability. Crystal structures with various PRMTs supported the observed specificity and selectivity.
Protein arginine methyltransferases (PRMTs) are important therapeutic targets, playing a crucial role in the regulation of many cellular processes and being linked to many diseases. Yet, there is still much to be understood regarding their functions and the biological pathways in which they are involved, as well as on the structural requirements that could drive the development of selective modulators of PRMT activity. Here we report a deconstruction-reconstruction approach that, starting from a series of type I PRMT inhibitors previously identified by us, allowed for the identification of potent and selective inhibitors of PRMT4, which regardless of the low cell permeability show an evident reduction of arginine methylation levels in MCF7 cells and a marked reduction of proliferation. We also report crystal structures with various PRMTs supporting the observed specificity and selectivity.
