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

BindingDB contains 3.2M data for 1.4M Compounds and 11.5K Targets. Of those, 1.6M data for 772K Compounds and 4.8K 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.

To help with training and testing AI and other models, BindingDB downloads and search results now provide the publication date and BindingDB curation date of each measurement.

To date, BindingDB has been supported by federal grants, which we greatly appreciate. However, the end of each grant cycle brings great uncertainty, and it would be enormously helpful if we could diversify our support base.
