Abstract

A series of novel phenol ether derivatives were designed, synthesized, and evaluated as non-covalent Proteasome inhibitors. Most compounds exhibited moderate to excellent Proteasome inhibitory activity. In particular, compound 18x proved to be the most potent compound (chymotrypsin-like: IC50 = 49 nM), exhibiting a 2-fold higher potency compared to the reported PI-1840. Besides, compound 18x exhibited excellent metabolic stability and selective anti-proliferative activity against solid Cancer cell lines including HepG2 and HGC27, providing incentive for the further development as a potential Anticancer agent against solid cancers.
