Bortezomib is a dipeptide (Phe-Leu), with a pyrazinoic acid protecting the N-terminus and a boronic acid replacing the C-terminal carboxylic acid. The boron atom is believed to interact with and inactivate the catalytic site on β subunits which form the active core of the proteasome, preferentially binding β5 active site [4
]. Bortezomib is the first-in-class proteasome inhibitor to be approved for clinical use.
Proteasome activity is reviewed in [3
The compound also has antimalarial activity. The Malaria
