Monomeric Targeted Protein Degraders.

The discovery and development of targeted protein degraders have become important areas of research in the field of medicinal chemistry. Inducing degradation of a target protein presents several advantages relative to simple inhibition including a potential for extended duration of action and more profound pharmacology. While engineered heterodimeric molecules have recently been a major focus within industry and academia, this Perspective highlights examples of targeted protein degradation observed for smaller, monomeric molecules. Methods and tools for evaluating protein degradation as well as a discussion of physical properties of monomeric vs engineered heterodimeric degraders are presented.
