Incorporation of Fluorinated Phenylalanine Generates Highly Specific Inhibitor of Proteasome’s Chymotrypsin-like Sites
摘要:
Proteasomal processing is conducted by three individual catalytic subunits, namely beta 1, beta 2, and beta 5. Subunit-specific inhibitors are useful tools In dissecting the role of these individual Subunits and are leads toward the development of antitumor agents. We here report that the presence of fluorinated phenyl-alanine derivatives in peptide based proteasome inhibitors has a profound effect on inhibitor potency and selectivity, Specifically, compound 4a emerges as one of the most beta 5 specific inhibitors known to date.
