Biological Activity for TCH-165

TCH-165 is an enhancer of 20S proteasome assembly. TCH-165 regulates the dynamic equilibrium between the 20S and 26S proteasome complexes, favoring 20S-mediated protein degradation. TCH-165 enhances the proteolytic activity of the 20S proteasome by increasing substrate accessibility to the 20S catalytic chamber through 20S gate opening. TCH-165 enhances 20S-mediated degradation of IDPs, α-syn, and tau in vitro, and does not induce the degradation of structured proteins such as GAPDH. TCH-165 enhances c-MYC degradation by the 20S proteasome, which reduces c-MYC levels in vivo, and is effective in bortezomib (Cat. No. 7282) resistant cells. TCH-165 down-regulates c-MYC target genes and inhibits cancer cell proliferation and tumor growth in vivo.

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.
