PROTAC

Read More about this category

PROTACs or Proteolysis Targeting Chimeric Molecules are heterobifunctional nanomolecules that theoretically target any protein for ubiquitination and degradation. In terms of the structure, PROTACs consist of one moiety which is recognized by the E3 ligase. This moiety is then chemically and covalently linked to a small molecule or a protein that recognizes the target protein. The trimeric complex formation leads to the transfer of ubiquitins to the target protein.

By removing target proteins directly rather than merely blocking them, PROTACs can provide multiple advantages over small molecule inhibitors, which can require high systemic exposure to achieve sufficient inhibition, often resulting in toxic side effects and eventual drug resistance. PROTAC molecules possess good tissue distribution and the ability to target intracellular proteins, thus can be directly applied to cells or injected into animals without the use of vectors.

Targeted protein degradation using the PROTAC technology is emerging as a novel therapeutic method to address diseases, such as cancer, driven by the aberrant expression of a disease-causing protein. In addition to the use of PROTACs for the treatment of human disease, these molecules provide a chemical genetic approach to “knock down” proteins to study their function. Currently, there are several small molecule inhibitors that have been found to show good biological activity by specifically targeting BET, estrogen receptor (ER), androgen receptor, etc.
