Processing small molecule databases is crucial for virtual screening and automated docking. This study surveys recent practices and highlights how molecular data preparation significantly impacts docking results.

Area of Science:

  • Computational chemistry and cheminformatics
  • Drug discovery and molecular modeling

Background:

  • Virtual screening (VS) utilizes small molecule databases for drug discovery.
  • Database processing optimizes molecular information (connectivity, stereochemistry, tautomers, conformation) for VS technologies.
  • Automated docking protocols rely on intermolecular atom-atom contacts for molecule ranking.

Purpose of the Study:

  • To survey and comment on recent practices in molecular data processing for virtual screening.
  • To investigate the impact of pre-processing protocols on automated docking results.
  • To highlight the emerging significance of ligand preparation in docking-based VS.

Main Methods:

  • Review of recent literature and practices in molecular database processing for VS.
