Chemical Name: N-[(Phenylmethoxy)carbonyl]-L-leucyl-N-[(1S)-1-formyl-3-methylbutyl]-L-leucinamide
Biological ActivityPotent cell-permeable inhibitor of proteasome (IC50 = 100 nM) and calpain (IC50 = 1.2 μM). Inhibits TNF-α-induced NF-κB activation and IκBα degradation. Induces neurite outgrowth in PC12 cells and has anticancer properties in vitro. Inhibits SARS-CoV-2 Mpro in vitro (IC50 = 3.9 μM) and inhibits viral replication. Also enhances adeno-associated viral transduction efficiency of human cell lines by around 50-fold.

Cells were treated with MG-132 (15 µM) for 18 hours in the absence or presence of GSK2656157 (10 µM)
It works well and dissolves perfectly in DMSO. I treated the cells with MG 132 (final concentration: 10 micromolar) in serum free medium for 24 hours.
