Described herein are compounds that are deubiquitinase inhibitors, methods of making pharmaceutical compositions and medicaments comprising such compounds, and methods of using such compounds in the treatment of conditions, diseases, or disorders that would benefit from inhibition of deubiquitinase activity.
Enantioselective aldol reactionsbetween substituted pyridine carbaldehydes and α‐ketoacids were shown to provide isotetronic acids or their corresponding pyridiniumsalts, depending on the nature of the substituents on the pyridine ring. The pyridiniumsalts were generated through nucleophilic attack of the pyridine nitrogen atom onto the reactive keto functional group. Moderate‐to‐good yields of
Piriqualone (1) was found to be an antagonist of AMPAreceptors. Structure activity optimization was conducted on each of the three rings in 1 to afford a series of potent and selective antagonists. The sterically crowded environment surrounding the N-3 aryl group provided sufficient thermal stability for atropisomers to be isolated. Separation of these atropisomers resulted in the identification of
