Small-molecule drug discovery has traditionally focused on occupancy of a binding
site that directly affects protein function, and this approach typically
precludes targeting proteins that lack such amenable sites. Furthermore, high
systemic drug exposures may be needed to maintain sufficient target inhibition in
vivo, increasing the risk of undesirable off-target effects. Induced protein
degradation is an alternative approach that is event-driven: upon drug binding,
the target protein is tagged for elimination. Emerging technologies based on
proteolysis-targeting chimaeras (PROTACs) that exploit cellular quality control
machinery to selectively degrade target proteins are attracting considerable
attention in the pharmaceutical industry owing to the advantages they could offer
over traditional small-molecule strategies. These advantages include the
potential to reduce systemic drug exposure, the ability to counteract increased
target protein expression that often accompanies inhibition of protein function
and the potential ability to target proteins that are not currently
therapeutically tractable, such as transcription factors, scaffolding and
regulatory proteins.
