Biological Activity for Carfilzomib

Carfilzomib is a potent irreversible proteasome inhibitor. Preferentially inhibits the chymotrypsin-like β5 subunit of the constitutive 20S proteasome (IC50 = 5.2 nM) and the β5i subunit of the immunoproteasome 20Si (LMP7; IC50 = 14 nM) in vitro with minimal cross-reactivity to other proteases. Exhibits little or no effect on PGPH and T-L activities. Activates prosurvival autophagy and induces cell apoptosis. Acts synergistically with dexamethasone (Cat. No. 1126). Suppresses tumor growth in an in vivo xenograft model. Decreases bone resorption and enhances bone formation in non-tumor bearing mice.

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.
