Drug Target Validation

Reveal your compound’s binding site with structural proteomics at peptide-level resolution

Biognosys’ novel Drug Target Validation service offers a unique way to confidently characterize a drug’s binding site and de-risk early drug development. By using our High Resolution Limited Proteolysis (HR-LiP) technology coupled with Mass Spectrometry, we remove the need for molecule tagging, protein modifications, or recombinant proteins. All we need is a cell line overexpressing your target of interest and a stock of your compound.

      Validating the target of a small molecule compound is key to both de-risking research pipelines and shortening a drug’s time to market. It can be achieved by confidently characterizing the compound’s binding site in its protein target. This provides valuable insights that can guide compound optimization.

      Our Drug Target Validation solution is part of our TrueTarget™ platform offering. Biognosys’ TrueTarget platform uses peptide-level information to enable both drug target deconvolution (LiP-MS) and further compound binding site characterization (HR-LiP) in a label-free manner. Collectively, these technologies empower drug discovery and optimization.

      The Drug Target Validation service can be performed on every kind of protein from all species in a near-native environment. Furthermore, traditionally difficult-to-characterize proteins, such as those with a high molecular mass or membrane localization, can be analyzed in their full length.

      In contrast to conventional structural biology techniques such as crystallography, our Drug Target Validation service leverages structural proteomics and offers a cost-efficient alternative with a few weeks of project turnaround time.

      Biognosys is the sole provider of proteomics solutions based on the patented LiP-MS technology, developed in collaboration with Prof. Paola Picotti Group at ETH Zurich.

      “We had previously enlisted other methods for target deconvolution and validation for our molecular glue program at the global protein structural readout level, including small molecule selectivity in cells. Biognosys’ TrueTargetTM (LiP-MS) platform provided a proteome-wide picture of our glue with peptide-level resolution. Analogous to HDX-MS on recombinant proteins, TrueTarget™ (LiP-MS) simultaneously provided information about conformational changes and small molecule binding sites in cells within one experiment. With Biognosys’ high-quality data and bioinformatics support, we could draw conclusions about endogenous target binding and compound selectivity, moving our program forward with high confidence.”
