説明
<jats:title>Abstract</jats:title><jats:p>Lysine and arginine methyltransferases participate in the posttranslational modification of histones and regulate key cellular functions. Protein arginine methyltransferase 1 (PRMT1) has been identified as an essential component of mixed lineage leukemia (MLL) oncogenic complexes, revealing its potential as a novel therapeutic target in human cancer. The first potent arginine methyltransferase inhibitors were recently discovered by random‐ and target‐based screening approaches. Herein we report virtual and biological screening for novel inhibitors of PRMT1. Structure‐based virtual screening (VS) of the Chembridge database composed of 328 000 molecules was performed with a combination of ligand‐ and target‐based in silico approaches. Nine inhibitors were identified from the top‐scored docking solutions; these were experimentally tested using human PRMT1 and an antibody‐based assay with a time‐resolved fluorescence readout. Among several aromatic amines, an aliphatic amine and an amide were also found to be active in the micromolar range.</jats:p>
