Reduce uncertainty. Validate target proteins faster.

Uncovering, selecting, and validating proteins is a time-intensive process that raises numerous questions. Reduce uncertainty before committing your team’s resources with detailed information on ligands, diseases, proteins, and more. With this vast, expert-curated data at your fingertips, your team can:

  • Conduct sequence searches to seek out white space and potential safety risks.
  • View related biomarkers to explore disease pathogenesis and protein pathways to prioritize relevant targets.

Narrow candidates with powerful tools and deep insights

Medicinal chemistry requires speed, accuracy, and a deep understanding of molecular behavior. Elevate your teams with a curated database of structure-activity relationships, ligand-target-disease combinations, and predictive panels so they can identify ligand sets faster and easier.

CAS BioFinder gives your medicinal chemists powerful methods to narrow their candidates.

  • Connect target protein-disease combinations to known ligands and compare options on druglikeness, commercial availability, and more.
  • Explore heat maps to find R-group modifications that impact ligand potency against a protein.
  • Predict bioactivity of a novel molecule to estimate its selectivity and identify safety risks.
