For compound screening and other applications in natural compound research

Originally developed by Dr. Hartmut Laatsch, the Wiley Identifier of Natural Products for Drug Discovery (AntiBase Library + ChemWindow) is a comprehensive database of more than 53,000 natural products and their chemical structures. This collection is key to scientists identifying natural products in pharmaceutical and other areas of research. It is known to be an effective screening tool for compounds with antimicrobial effects that have already been studied.

Key features:

    • Data-rich property fields. Valuable metadata included for each record where available:
      Compound Properties - molecular formula, mass, composition, class, geo-location
      Physico-Chemical Data - melting point, optical rotation
      Spectroscopic Data - IR, HRMS, MS, UV, plus high-quality predicted 13C NMR data generated using Wiley's proprietary NMR prediction algorithm. 
      Related References - direct DOI literature link, Human Metabolome Database
  • Carefully curated and verified data. Data collected from primary and secondary literature; then carefully checked and validated with key references and sources provided as a data field.
  • Now includes Wiley's ChemWindow software for advanced data mining. Search the entire AntiBase collection using ChemWindow's advanced data search and mining features. Also includes ChemWindow's renowned tools for structure drawing, reporting, and building your own databases. 

What's New in the 2022 Release?

  • More compounds than ever. 5,000 new compounds added for expanded natural product coverage to over 53,000 compounds.
  • Added DOIs to even more records. DOI links to even more records for quick access to additional information about compounds in the literature.
