1.3. ChEMBL: literature-extracted biological activity information

        ChEMBL (https://www.ebi.ac.uk/chembl/)^9,10 is a large bioactivity database, developed and maintained by the European Bioinformatics Institute (EBI), which is part of the European Molecular Biology Laboratory (EMBL).  The core activity data in ChEMBL are “manually” extracted from the full text of peer-reviewed scientific publications in select chemistry journals, such as Journal of Medicinal Chemistry, Bioorganic Medicinal Chemistry Letters, and Journal of Natural products.  From each publication, details of the compounds tested, the assays performed and any target information for these assays are abstracted.  ChEMBL also integrates screening results and bioactivity data from other public databases (such as PubChem BioAssay) and information on approved drugs from the U.S. FDA Orange Book¹¹ and the NLM’s DailyMed¹².
