Background:

MG-262 (also known as Z-Leu-Leu-Leu-B(OH)2), a boronic peptide acid, is a potent proteasome inhibitor that selectively and reversibly inhibits the chymotryptic activity of the proteasome. It consists of a peptide and boronic acid moiety which are functional to proteasome inhibition. According to previous studies, MG-262 is capable of reducing the viability of nasal mucosa and polyp fibroblasts, provoking cell growth arrest, inhibiting DNA replication and retinoblastoma phosphorylation, increasing expression of the cell cycle inhibitor p21 and p27, and inducing cell death via loss of mitochondrial membrane potential, caspase-3 and poly(ADP-ribose) polymerase activation, induction of c-Jun phosphorylation and mitogen-activated protein kinase phosphatase-1 expression.
