Biological Activity for MZ 1
MZ 1 is a cell penetrant Degrader (PROTAC®) based on (+)-JQ1 (Cat.No. 4499) conjugated to a von Hippel-Lindau (VHL) ligand. MZ 1 induces preferential degradation of BRD4 over BRD2 and BRD3 (DC50 values for degradation of BRD4 are 8 and 23 nM in H661 and H838 cells, respectively), while retaining high affinity for BRD2, BRD3 and BRD4 bromodomains (Kd = 13-60 nM). MZ 1 induces complete degradation of BRD4 at a concentration of 100 nM, whereas complete degradation of BRD2/3 is achieved at 2 μM. Potent cytotoxicity and antiproliferative effects are exhibited in AML cell lines (pEC50 = 7.6 in Mv4-11 cells).
Negative control cis MZ 1 also available.

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
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
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.
