Degrader Building Blocks

Tocris provides Building Blocks to support Degrader research and development. Degraders (e.g. PROTAC® molecules, SNIPERs etc) are heterobifunctional small molecules that are modular in design, comprising binding moieties for an E3 ubiquitin ligase and a target protein joined by a linker. Our Degrader components have functional handles for easy conjugation to ligands/linkers of interest. The range includes the most effective and commonly used E3 ubiquitin ligase ligands, functionalized at positions known not to interfere with binding affinity. E3 ligase ligands conjugated to common linker groups are also supplied. Below you will find a toolbox of Degrader Building Blocks to support targeted protein degradation research and development. You can also select your own panel of E3 ligase ligands + linkers for your Degrader development program using our new PROTAC Panel Builder tool.

    Developing Degraders Poster

    This poster describes the generation of a database of Degraders (PROTACs®) from the literature. The Degraders were profiled according to the constituent ligands, linker type, linker length and physicochemical properties and this information was used to establish a set of guidelines for the design and synthesis of cell-permeable Degrader molecules. Presented at the 20th SCI/RSC Medicinal Chemistry Symposium 2019, Cambridge, UK.

    Enabling Research By Provision of Chemical Tools Poster

    Enabling Research By Provision of Chemical Tools Poster

    The Tocris chemistry team has considerable chemistry knowledge and skill which it has recently been applying to the generation of new chemical probes from known tools and compounds to help answer biological questions. This poster presents some of the work carried out by Tocris scientists and focuses on two areas: the generation of libraries of chemical building blocks to support Degrader (PROTAC) research and the development of a fluorescent probe to study integrin biology. Presented at Chemical Tools for Complex Biological Systems II, 2019, Janelia Research Campus, USA.
    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.
