The first public molecular recognition database, BindingDB supports research, education and practice in drug discovery, pharmacology and related fields.

BindingDB contains 2.8M data for 1.2M Compounds and 9.2K Targets. Of those, 1,346K data for 622K Compounds and 4.5K Targets were curated by BindingDB curators. BindingDB is a FAIRsharing resource.

If BindingDB was of value to your research, please take a moment to donate to this nonprofit project. Your donation will let us provide you with more data and improved service.

Linking into BindingDB


The following generic search URLs allow you to link into BindingDB by protein, small molecule, PDB ID, and/or PubMed ID. Please feel free to suggest other search methods.

  1. Protein ("target") Links
  2. Small molecule ("compound") Links
  3. Protein Data Bank ID (PDB ID)
    BindingDB provides hard links to binding data corresponding to a specific PDB entry if the BindingDB Target is >85% identical to the protein in the PDB entry, according to BLAST, and if the ligand in the PDB entry is identical to the ligand in BindingDB.
