Biological Activity for dBET1

dBET1 is a Degrader (PROTAC®) comprising BET bromodomain antagonist (+)-JQ1 (Cat. No. 4499) conjugated to a cereblon E3 ubiquitin ligase ligand. Depletes BET bromodomains in cancer cell lines in vitro (EC50 = 430 nM in breast cancer cells) and induces apoptosis. Delays tumor growth and downregulates MYC in mice bearing human AML xenografts. Antibody validated for Western Blot also available: NBP2-77359.

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.
