4-Methyl-1,2,3-Triazoles as N -Acetyl-Lysine Mimics Afford Potent BET Bromodomain Inhibitors with Improved Selectivity.
J.Med.Chem., 64:10497-10511, 2021

PubMed Abstract: The bromodomain and extra terminal (BET) protein family recognizes acetylated lysines within histones and transcription factors using two N-terminal bromodomains, D1 and D2. The protein-protein interactions between BET bromodomains, acetylated histones, and transcription factors are therapeutic targets for BET-related diseases, including inflammatory disease and cancer. Prior work demonstrated that methylated-1,2,3-triazoles are suitable -acetyl lysine mimetics for BET inhibition. Here we describe a structure-activity relationship study of triazole-based inhibitors that improve affinity, D1 selectivity, and microsomal stability. These outcomes were accomplished by targeting a nonconserved residue, Asp144 and a conserved residue, Met149, on BRD4 D1. The lead inhibitors and have a BRD4 D1 of 12 and 6.4 nM, respectively. Cellular activity was demonstrated through suppression of c-Myc expression in MM.1S cells and downregulation of IL-8 in TNF-α-stimulated A549 cells. These data indicate that and are new leads to investigate the anticancer and anti-inflammatory activity of BET proteins.
