This study proposes an empirical scoring system to prioritize drug discovery hits from high-throughput screening (HTS). The system evaluates chemical structures and toxicity data, aiding in selecting promising compounds for further research.

Area of Science:

  • Medicinal Chemistry
  • Drug Discovery
  • Computational Chemistry

Background:

  • High-throughput screening (HTS) generates numerous hits, necessitating efficient prioritization methods.
  • Evaluating compound chemotypes and potential toxicity is crucial for effective drug development.

Purpose of the Study:

  • To develop and illustrate an empirical scheme for evaluating and prioritizing HTS hits.
  • To assist decision-making in selecting compounds for further experimentation.

Main Methods:

  • Assigning negative scores based on known toxic chemotypes (MDDR, WOMBAT, TOXNET) or positive toxicity results.
  • Assigning positive scores for high biological activity, negative toxicity literature findings, and favorable drug-like properties.
  • Emphasizing aqueous solubility estimation for prioritizing in vivo studies.

Main Results:

  • Demonstrated the application of the scoring scheme to G-protein coupled receptor antagonists.
  • Validated the decision-making process using a literature example of dihydrofolate reductase inhibition.

Conclusions:

  • The proposed empirical scheme provides a systematic approach to prioritize HTS hits.
  • This method aids in selecting promising chemotypes and compounds, optimizing the drug discovery pipeline.
