(S)-MG115

(S)-MG115 is a potent and reversible proteasome inhibitor, targeting the chymotryptic site on the 20S particle (Ki = 21 nM). It reduces the degradation of ubiquitin-conjugated proteins in extracts. (S)-MG115 also blocks the degradation of long- and short-lived proteins in intact cells as well as the proteolytic generation of diverse proteins, including NF-kappaB, antigens, and p53. Proteasome inhibitors, including (S)-MG115, can induce a heat shock response and apoptosis, particularly in cancer cells.Formal Name: N-[(phenylmethoxy)carbonyl]-L-leucyl-N-[(1S)-1-formylbutyl]-L-leucinamide.
