Target Protein Degradation – Transformative Approach to Selectively Eliminate Disease-Causing Protein

Pharma

Targeted protein degradation is an emerging therapeutic modality that has the potential to enable the treatment of difficult-to-treat diseases. While conventional medicines, such as small molecule inhibitors and monoclonal antibodies, address fewer than 20% of the proteome, TPD offers a unique means to tap into the rest of the vast, unexplored proteome. Through TPD, a disease can be addressed by controlling the amount of a harmful protein rather than trying to modulate or inhibit its function. The control of protein levels is accomplished with a small molecule drug, called a protein degrader. Targeted protein degraders are bifunctional small molecules that recruit E3 ubiquitin ligases to the protein of interest and mediate its ubiquitination and subsequent proteolysis by the proteasome. Small molecule-mediated selective targeting of protein degradation has several advantages over traditional drug discovery strategies. One of the primary advantages is the high degree of target specificity that can be rapidly validated by leveraging the multiple layers of selectivity in the cellular machinery. Moreover, owing to the fact that the degrader molecules cannot be destroyed, they can cause the destruction of many copies of the harmful protein and reduce systemic drug exposure. In addition, it can counteract increased target protein expression by inhibiting the protein function. It is worth noting that a single protein degrader has the ability to potentially eliminate multiple disease-causing proteins through proteasome degradation of the target protein. However, an inhibitor drug can only block a single disease-causing protein at a time. The following figure highlights the difference between a protein degrader and a protein inhibitor.

Protein degraders represent a new class of chemical tools that have the power to ablate all the functions of a drug target at once, including scaffolding and catalytic functions which are difficult to target with small molecule inhibitors. This shift from inhibition of the target protein to its removal gives a greater degree of temporal control and provides therapeutic options that extend beyond the druggable target space. Various type of protein degraders are mentioned in the figure.

It is important to note that in contrast to the traditional small molecule inhibitors and antibody drugs, protein degraders are designed to develop drug candidates for many intractable diseases that other therapeutic modalities cannot address. Furthermore, various factors, such as technological advancements, growing interest and extensive research, and rise in partnering activity and capital investments, in this sector would continue to be a huge contributing force towards the progression of this niche market. These promising developments and an in-depth analysis of the essential obstacles could result in this technology to be increasingly implemented across multiple therapeutic areas.
