Abstact

We report the analysis of an in-house fragment screening campaign for the oncology target MEK1. The application of virtual screening (VS) as a primary fragment screening approach, followed by biophysical validation using differential screening fluorimetry (DSF), with resultant binding mode determination by X-ray crystallography (X-ray), is presented as the most time and cost-effective combination of in silico and in vitro methods to identify fragments. We demonstrate the effectiveness of the VS-DSF workflow for the early identification of fragments to both 'jump-start' the drug discovery project and to complement biochemical screening data.
