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.

Epigenetics Scientific Review

Epigenetics Scientific Review

Written by Susanne Müller-Knapp and Peter J. Brown, this review gives an overview of the development of chemical probes for epigenetic targets, as well as the impact of these tool compounds being made available to the scientific community. In addition, their biological effects are also discussed. Epigenetic compounds available from Tocris are listed.

Epigenetics in Cancer Poster

Epigenetics in Cancer Poster

This poster summarizes the main epigenetic targets in cancer. The dysregulation of epigenetic modifications has been shown to result in oncogenesis and cancer progression. Unlike genetic mutations, epigenetic alterations are considered to be reversible and thus make promising therapeutic targets.

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.
