Biological Activity for MG 132

MG 132 is a potent cell-permeable inhibitor of proteasome (IC50 = 100 nM) and calpain (IC50 = 1.2 μM). MG 132 inhibits TNF-α-induced NF-κB activation and IκBα degradation. Induces neurite outgrowth in PC12 cells and has anticancer properties in vitro. MG 132 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.

Targeted Protein Degradation Poster

Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed.
