BindingDB Data Curation

BindingDB curates US Patents. We have scanned patents back to 2013 for suitable data and are currently up to date as of mid-2020. However, we cannot be sure of capturing all relevant patents, so if you know of a useful one we have missed, please let us know and we will try to curate it. As of June 27, 2024, BindingDB's patent dataset comprises:

  1. Patents: 7,164
  2. Binding measurements: 1,116,900
  3. Compounds: 542,126
  4. Target proteins: 2,685
  5. Assays: 10,275
  6. Average Number of Targets per Patent: 1.91

BindingDB curates a set of journals not covered by other public databases. As of June 27, 2024, the status of this curation effort is as follows:

BindingDB is supported by NIH's National Institute of General Medical Sciences (R24GM144232), and is located at the Skaggs School of Pharmacy and Pharmaceutical Sciences of the University of California San Diego
