Reviewing the toolbox for degrader development in oncology

Abstract

The field of targeted protein degradation encompasses a growing number of modalities that achieve potent and selective knockdown of target proteins at the post-translational level. Among the most clinically advanced are bifunctional small-molecule degraders, also referred to as PROteolysis Targeting Chimeras, Degronimids, SNIPERs, or uSMITEs. Although applicable to many disease indications, oncology stands to be the first to benefit from this promising therapeutic approach, with the first investigational new drugs (INDs) filed in 2019 and a proliferation of research specifically focused on harnessing degraders for cancer treatment. In this review, we consider the toolbox of guidelines, reagents, and technologies that has evolved alongside the field to support degrader research and development.
