Introduction The IUPHAR/BPS Guide to PHARMACOLOGY (GtoPdb) is an open, expert-driven database of pharmacological targets and the substances that act on them [1]. It is a joint initiative between the British Pharmacological Society (BPS) and the International Union of Basic and Clinical Pharmacology (IUPHAR), which aims to cover the human targets of licensed drugs and other likely targets of future therapeutics. The information is presented at two levels: 1. Overviews of the key properties, selective ligands and further reading for a wide range of human biological targets, which form the basis for the Concise Guide to PHARMACOLOGY (CGTP) [2]. 2. Detailed pharmacological, functional and clinical information for a subset of important targets. All data are manually curated from the primary literature and reviewed by an international network of >500 experts in 96 subcommittees of the IUPHAR Committee on Receptor Nomenclature and Drug Classification (NC-IUPHAR). ~1,700 established or potential data-supported drug targets ~1,100 additional related proteins • G protein-coupled receptors (GPCRs), including Orphan GPCRs & Adhesion GPCRs • Voltage-gated ion channels (VGICs) • Ligand-gated ion channels (LGICs) • Other ion channels • Nuclear hormone receptors (NHRs) • Enzymes, including kinases & proteases • Catalytic receptors • Transporters ~9,000 ligands • Approved drugs • Experimental compounds & labelled ligands • Hormones, neurotransmitters, metabolites • Endogenous and synthetic peptides • Antibodies • Natural products • Inorganic chemicals Various search tools are available to find targets and ligands by keyword (Fig. 2), identifier, reference, chemical structure (Fig. 3), or protein sequence (Fig. 4).

Navigating target and ligand families Targets are organised by class, which can be browsed as a tree with families and subfamilies (Fig. 5). Ligands have also recently been organised into related families and groups (Fig. 6). Each family/group page lists summary information for the ligands, with links to more detailed pages (Fig. 7).

It combines pharmacological parameters from GtoPdb with ligand binding data from the RCSB Protein Data Bank [4] (Fig. 9). It is freely available at Figure 9. (A/B) The location of a ligand binding sequence is shown in green on a protein structure. (C) A residue distance matrix indicating ‘globularity’ of the sequence. The dotted line represents the binding sequence – the greener the area is the more compact the sequence. A B C 5. Comparing ligand affinity across species Ligand activity graphs provide a quick way to visualise affinity at different targets and across species. Box plots (Fig. 8A) summarise standardised activity data from GtoPdb and ChEMBL [3]. Individual data points, assay details and references are provided in an accompanying table (Fig. 8B). Figure 8.

Downloading data Data are available to download in various formats: • Lists of targets, ligands and interactions in CSV format • REST web services for computational access to data in JSON format • SQL database dump files • Interaction data are now available in RDF format for semantic integration
