Advantages and Disadvantages of PROTACs

The present paper discusses the significant impact of Proteolysis Targeting Chimeras (PROTACs) in targeted protein degradation, presenting a paradigm shift from traditional drug inhibition to protein elimination. PROTACs offer a versatile approach to degrade “undruggable” proteins, expanding the range of potential therapeutic targets. By exploiting the ubiquitin-proteasome system, PROTACs induce the degradation of specific proteins, overcoming limitations associated with protein structure and function. The catalytic degradation function of PROTACs enables efficient and sustained protein elimination, enhancing therapeutic outcomes. Additionally, PROTACs can be combined with other modalities to synergistically target challenging proteins, such as oncogenes and proteins involved in complex interaction networks. While PROTACs hold great promise in improving treatment outcomes, ongoing research and innovation are essential to address challenges like intracellular delivery. Overall, PROTACs represent a groundbreaking approach to drug discovery, offering enhanced selectivity, specificity, and therapeutic potential in various diseases characterized by dysregulated protein expression.
