Targeted protein degradation has exploded over the past several years due to preclinical and early clinical therapeutic success of numerous compounds, and the emergence of new degradation modalities, which has broadened the definition of what a degrader is. The most characterized and well-studied small molecule degraders are molecular glues and proteolysis targeting chimeras (PROTACs). These degraders induce a ternary complex between a target protein, degrader, and E3 ligase component, resulting in ubiquitination and subsequent degradation of the target protein via the ubiquitin proteasomal system (UPS). This event-driven process requires success at all steps through a complex cascade of events. As more systems, degraders, and targets are tested, it has become increasingly clear that achieving degradation is only the first critical milestone in a degrader development program. Rather highly efficacious degraders require a combination of multiple optimized parameters: rapid degradation, high potency, high maximal degradation (Dmax), and sustained loss of target without re-dosing. Success to meet these more rigorous goals depends upon the ability to characterize and understand the dynamic cellular degradation profiles and relate them to the underlying mechanism for any given target treated with a specific concentration of degrader. From this starting point, optimization and fine tuning of multiple kinetic parameters such as how fast degradation occurs (the rate), how much of the target is degraded (the extent), and how long the target remains degraded (the duration) can be performed. In this review we explore the diversity of cellular kinetic degradation profiles which can arise after molecular glue and PROTAC treatment and the potential implications of these varying responses. As the overall degradation kinetics are a sum of individual mechanistic steps, each with their own kinetic contributions, we discuss the ways in which changes at any one of these steps could potentially influence the resultant kinetic degradation profiles. Looking forward, we address the importance in characterizing the kinetics of target protein loss in the early stages of degrader design and how this will enable more rapid discovery of therapeutic agents to elicit desired phenotypic outcomes.
