The Ion Channel Database is the Aureus Sciences' knowledge base containing voltage and ligand-gated ion channels, ligand-relevant chemical information associated with quantitative biological activities and mechanisms of action.
All chemical and bioactivity data are organized in an Oracle database according to the Aureus relational data model.
- Structure-activity data culled from international scientific journals and patents (US, Euro & international)
- All ion channel targets: voltage-gated, ligand-gated channels and other families
- Detailed descriptions of the experimental methods and conditions used to generate activity data points
- Data organized in relational tables according to: chemical information, protein target information, bioactivity and experimental methods
Uses
Medicinal chemists, cheminformaticians, pharmacologists and biologists use the knowledge base to: - Retrieve ligands tested as blockers, openers or activators of an ion channel
- Retrieve selective molecules for a specific ion channel vs. another
- Assess ligands’ mechanism of action, study structure activity relationships to guide compound optimization
- Access in vitro and in vivo pharmacological activity data, materials and methods used
- Search records via text and numeric queries (biological activity and biological data field searches)
- Export data to SD files, .txt and .xls formats
Chemical Information - Registered ligands always associated with at least one quantitative experimental biological data
