Biological Activity for WS 383

WS 383 is a potent and reversible DCN1-UBC12 interaction inhibitor (IC50 = 11 nM). The compound displays selectivity for DCN1-UBC12 over inhibition of a panel of kinases. including Bruton's tyrosine kinase (BTK), cyclin-dependent kinases (CDKs) and epidermal growth factor receptor (EGFR). In vitro, WS 383 selectively inhibits cullin-3 neddylation over other cullins, and induces accumulation of p21, p27 and NRF2.

Programmed Cell Death Poster

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.

Targeted Protein Degradation Poster

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.
