Biological Activity for MS 154

MS 154 is a potent and selective cereblon-recruiting Degrader (PROTAC®) of mutant epidermal growth factor receptor (EGFR), comprising a cereblon-binding moiety joined by a linker to gefitinib (Iressa, Cat. No. 3000). MS 154 decreases EGFR protein levels, inhibits downstream signaling in and inhibits proliferation of mutant EGFR-bearing lung cancer cells (DC50 values are 11 and 25 nM in HCC-827 and H3255 cells, respectively; Dmax > 95% at 50 nM), but not in WT-EGFR-bearing ovarian and lung cancer cells lines. Bioavailable in mice following ip administration.

Negative control (Cat. No. 7396) and EGFR antibody validated for Simple Western™ (automated Western) instruments and Western Blot also available: Catalog # AF231.

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.
