The IUPHAR/BPS Guide to PHARMACOLOGY in 2026
Abstract
The IUPHAR/BPS Guide to PHARMACOLOGY (GtoPdb, https://www.guidetopharmacology.org) is an open-access database of expert-curated, high-quality pharmacological data. It provides succinct overviews and key references for pharmacological targets and their recommended experimental ligands, alongside detailed information about ligand-target activities. It includes 3103 protein targets and 13 260 ligand molecules, including approved drugs, small molecules, peptides, and antibodies. Here, we report recent improvements to the resource and describe expansion in content over the seven database releases made during the last two years. We describe developments in antibacterial pharmacology, work that has been supported through our collaboration with AntibioticDB and Global Antibiotic Research and Development Partnership. We discuss recent areas of curation, including natural products and nucleic acids, and describe an improved presentation of our approved drugs set that contains new therapeutic targets and ligands that are proposed as modulators with clinical potential. This is a useful new resource, both in being continuously updated and having coverage across multiple approval agencies. Maintaining strong links to external resources, such as PubChem, remains an important feature of GtoPdb, and here we highlight their value and utility in being a FAIR-compliant resource. We also present a comparison of our data coverage with ChEMBL and BindingDB.
