ELIXIR-A

ELIXIR-A refines pharmacophores and identifies receptor–ligand interaction points to support computer-aided drug design.

Key Features:

• Implementation: Python-based pharmacophore refinement tool.
• Pharmacophore refinement: Refines pharmacophores derived from multiple ligands across different receptors.
• Conformation filtering: Filters pharmacophore points resulting from analysis of multiple ligand conformations.
• Interaction identification: Identifies interaction points between receptor–ligand complexes within receptor active sites.
• Virtual screening compatibility: Generates refined pharmacophores for integration into virtual pharmacophore-based screening platforms.
• Precision enhancement: Produces a more precise representation of potential interaction sites within receptor active sites.

Scientific Applications:

• De novo drug design: Supports de novo drug design by refining interaction points to inform novel scaffold generation.
• Lead identification: Aids lead identification through refined pharmacophore models derived from multiple ligands.
• Virtual screening optimization: Enhances pharmacophore models used during virtual screening and optimization.
• Multi-target drug design: Refines pharmacophores across different receptors to support multi-target drug design strategies.

Methodology:

Python-based refinement of pharmacophores derived from multiple ligands by filtering pharmacophore points from analyses of multiple ligand conformations and identifying receptor–ligand interaction points.
