Abstract

Screening of a library of diverse heterocyclic scaffolds identified substituted quinolines as inhibitors of the human Proteasome. The heterocyclic library was prepared via a novel titanium-catalyzed multicomponent coupling reaction, which rendered a diverse set of isoxazoles, pyrimidines, pyrroles, pyrazoles and quinolines. SAR of the parent lead compound indicated that hydrophobic residues on the benzo-moiety significantly improved potency. Lead compound 25 inhibits the chymotryptic-like proteolytic activity of the Proteasome (IC50 5.4μM), representing a new class of nonpeptidic, noncovalent Proteasome inhibitors.
