Integrating biophysics with HTS driven drug discovery projects

Although biophysical protein–ligand studies are established HTS hit triaging tools, this review will show how further impact can be made by deploying biophysics during HTS assay development itself.

Over the past decade biophysics has become an established discipline in HTS hit triaging, owing to its high fidelity in detecting protein–ligand interactions. Many pharma companies are using biophysical techniques to filter HTS output for false positives, as will be discussed in this review. Moreover, I will demonstrate how the earlier application of biophysics, already at the HTS assay development stage, is potentially even more impactful. Two key areas here are early mode-of-action studies and ensuring that the HTS assay and subsequent cascade are fit for purpose. Top-level results from 20 in-house projects are shown to underpin the impact of these studies.
