How to use

In Vitro:

(R)-MG-132, the stereoisomer of MG-132, is studied as a potential inhibitor of chymotrypsin-like, trypsin-like, and peptidylglutamyl peptide hydrolyzing activities of proteasome[1]. MG-132 and (R)-MG-132 are investigated for inhibition of ChTL, trypsin-like (TL) and peptidylglutamyl peptide hydrolyzing (PGPH) activities of purified 20S proteasomes isolated from human erythrocytes. For MG-132, the IC50s of 0.89 μM, 104.43 μM, and 5.7 μM for ChTL, TL, and PGPH, respectively. For (R)-MG-132, the IC50s of 0.22 μM, 34.4 μM, and 2.95 μM for ChTL, TL, and PGPH, respectively[1].

In Vivo:

Administration of (R)-MG-132 effectively rescues the expression levels and plasma membrane localization of dystrophin, β-dystroglycan, α-bdystroglycan, and α-sarcoglycan in skeletal muscle fibers from mdx mice, reduces muscle membrane damage, and ameliorates the histopathological signs of muscular dystrophy. (R)-MG-132 treatment significantly reduces immobilization-induced skeletal muscle atrophy in mice, by downregulating the muscle-specific ubiquitin ligases atrogin-1/MAFbx and MuRF-1 mRNA.
