Extensively validated and fully automated docking with Surflex-Dock

Access top-tier docking enrichment and accurate pose prediction with reliable automated docking procedures. Automate protein preparation and reduce inappropriate bias with Surflex-Dock’s easy-to-use workflows. Surflex-Dock supports your 3D structure-based design efforts, allowing you to model ligands from small molecules to large macrocycles.

With Surflex-Dock, ensembles of protein conformations take into account the variability in the binding pocket and relevant interactions, to give a more realistic picture of molecular docking.

Surflex-Dock enables highly accurate non-cognate ligand docking, so you can correctly predict poses for future potential ligands for your protein complex, making use of known prior bound ligand poses with eSim.

Explore 3D structure-activity relationships with eSim

Looking for fast, reliable 3D ligand-based drug design and virtual screening? eSim considers molecular similarity from a protein’s perspective of a ligand, creating a surface representation of the molecule based on shape, electrostatic field, and hydrogen-bond preferences. This information can then be used to:

  • Carry out large scale, high performance 3D virtual screening against known actives to find novel potent compounds
  • Achieve significantly higher enrichment in your virtual screens than leading competitors
  • Inform 3D design with industry-leading pose prediction

eSim is also available as part of our StarDrop drug discovery platform, so you can include 3D ligand-based drug design as part of your integrative, intuitive drug discovery workflow.

Predict binding affinities with QuanSA

The BioPharmics QuanSA (Quantitative Surface-field Analysis) method lets you predict the affinity of your ligands using machine learning models based on physical principles. QuanSA’s 3D ligand-based models achieve equivalent accuracy to market-leading methods such as FEP+, while providing transferablility, even across scaffolds. With QuanSA, you can:

  • Predict binding affinity without protein structural information
  • Build accurate affinity models, even with only a small number of known actives
  • Find novel active compounds with prediction confidence metrics
