Ligand.Info offers a vast, downloadable Meta-Database of over one million small molecules for drug discovery. This resource aids in virtual screening, identifying potential antiviral drugs and inhibitors.

Area of Science:

  • Medicinal Chemistry
  • Computational Chemistry
  • Pharmacology

Background:

  • Small molecule databases are crucial for drug discovery and development.
  • Publicly available data on small molecules, including structural and activity information, is fragmented.
  • Efficient tools are needed to access and analyze large chemical datasets for identifying potential drug candidates.

Purpose of the Study:

  • To introduce Ligand.Info, a comprehensive Meta-Database of small molecules.
  • To provide a user-friendly tool for interactive screening and similarity searching of chemical compounds.
  • To demonstrate the utility of the Meta-Database for virtual high-throughput screening in drug discovery.

Main Methods:

  • Compilation of over one million entries from various public small molecule databases.

  • Inclusion of calculated 3D coordinates and biological activity data for compound records.
  • Development of a Java-based tool for interactive clustering and similarity searching of molecules.
  • Facilitation of automatic downloading of similar molecules from the server.

    • Main Results:

    • The Ligand.Info Meta-Database contains over one million small molecule entries.
    • Compound records include 3D coordinates and information on biological activity, FDA drug status, and anti-HIV activity.
    • The Java-based screening tool enables interactive analysis and retrieval of similar compounds.
    • Successful identification of antiviral drugs and inhibitors using known antiviral drugs as queries.

    Conclusions:

    • Ligand.Info provides a valuable, centralized resource for researchers in drug discovery.
    • The integrated screening tool enhances the efficiency of virtual high-throughput screening.
    • The Meta-Database demonstrates potential for identifying novel therapeutic agents, including antivirals.
