Carboxylic Acid Isostere Derivatives of Hydroxypyridinones as Core Scaffolds for Influenza Endonuclease Inhibitors.
Acs Med.Chem.Lett., 14:75-82, 2023

PubMed Abstract: Among the most important influenza virus targets is the RNA-dependent RNA polymerase acidic N-terminal (PA) endonuclease, which is a critical component of the viral replication machinery. To inhibit the activity of this metalloenzyme, small-molecule inhibitors employ metal-binding pharmacophores (MBPs) that coordinate to the dinuclear Mn active site. In this study, several metal-binding isosteres (MBIs) were examined where the carboxylic acid moiety of a hydroxypyridinone MBP is replaced with other groups to modulate the physicochemical properties of the compound. MBIs were evaluated for their ability to inhibit PA using a FRET-based enzymatic assay, and their mode of binding in PA was determined using X-ray crystallography.
