Biological Activity for SJF 1528

SJF 1528 is a potent EGFR PROTAC® Degrader (DC50 values are 39.2 nM for wild-type EGFR in OVCAR8 cells and 736 nM for Exon20Ins mutated EGFR in HeLa cells). Also degrades HER2. SJF 1528 comprises the EGFR inhibitor Lapatinib (Cat. No. 6811) joined by a linker to a von Hippel-Lindau (VHL) recruiting ligand. Inhibits proliferation of HER2-driven breast cancer cell lines (IC50 = 102 nM for SKBr3 cells).

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.
