Design, synthesis, and biological evaluation of novel phenol ether derivatives as non-covalent proteasome inhibitors

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.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 20744-39-2 is helpful to your research. 20744-39-2

General procedure: To a flame-dried flask was added 8 (0.046g, 0.142mmol), xantphos (0.016g, 0.028mmol), potassium carbonate (0.392g, 2.83mmol), palladium(II) acetate (0.003g, 0.014mmol), and the respective amine (0.170mmol). The flask was purged with nitrogen three times and then anhydrous dioxane (1.5mL) was added under nitrogen. The reaction was refluxed at 105C for 12h while under nitrogen, maintaining a positive pressure. The mixture was concentrated under reduced pressure, separated by silica column chromatography (dichloromethane/isopropanol), and purified by reverse phase chromatography (water/acetonitrile).
