Biological Activity for SK 575

SK 575 is a potent PARP1 Degrader (PROTAC®; DC50 ≤ 6.72 nM, >99% PARP1 degradation at 10 nM). It comprises the PARP1/2 inhibitor Olaparib (Cat. No. 7579), joined by a linker to cereblon/cullin 4A ligand Thalidomide (Cat. No. 0652). SK 575 inhibits the growth of various cancer cell lines bearing BRCA1/2 mutations with IC50 values in the nanomolar range. It effectively reduces PARP1 protein levels in mouse SW620 tumor xenograft models. SK 575 dose-dependently potentiates the antitumor activity of Temozolomide (Cat. No. 2706) and Cisplatin (Cat. No. 2251) in vivo.

PARP antibodies validated for Simple Western™ (automated Western) instruments and Western Blot also available: Catalog # AF-600-NA and MAB8095.

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.
