Benzyloxycarbonyl- L-Leucyl- L-Leucine- L-Leucinal
Inhibitor for Proteasome and Cathepsin K
Z-Leu-Leu-Leu-aldehyde [MG-132] is very strong inhibitor of calpain
The selective proteasome inhibitor MG-132 (Calpain Inhibitor IV) is a tripeptide aldehyde with the sequence Z-Leu-Leu-Leu-H (aldehyde) and is depending to its hydrophob sequence poorly soluble in water or in aqueous buffers. MG-132 is soluble in several organic solvents like DMSO (25 mg/ml), Ethanol (25 mg/ml), Methanol or DMF. To prepare aqueous stock solutions, MG-132 should be dissolved first in organic solvents and then carefully diluted into aqueous buffers. Aqueous stock solutions of Z-Leu-Leu-Leu-H [MG132] should not be stored for longer, because of the terminal aldehyde, which is subject to oxidation. MG-132 (Z-Leu-Leu-Leu-aldehyde) will be shipped at room temperature and should be stored after receipt in a freezer.
It is reported that the combination of MG-132 with the proteasomal inhibitor Lactacystin may induce synergistic apoptosis in prostate cancer cells.
