Abstract

This database (GtoPdb) is a leading on-line resource of key relationships in molecular pharmacology, encompassing a network of ~8000 ligands X ~1500 human proteins they quantitatively interact with (PMID 26464438). It has been used by researchers and educators worldwide since its first incarnation as IUPHAR-DB in 2009. This presentation will address who might use this resource and how . Ways to navigate pharmacological relationships and drug mechanisms of action will be shown for the web interface, target hierarchy and cross-references to other resources. In addition our new educational site will be introduced as well as the latest set of “Concise Guide” overview papers (PMIDs 26650438-46) derived directly from the database content.

>8000 ligands and drugs:• Approved drugs• Synthetic organic compounds• Metabolites, hormones, neurotransmitters• Natural products• Endogenous peptides• Other peptides• Inorganics• Antibodies• Labelled ligands

GtoPdb content - ligands

Ligand numbers as of December 2014

6

Concise target family summaries• Concise target family summaries introducing the main

properties • Expert overviews and comments• Selective ligands, clinicically-used drugs, endogenous

ligands and probes (radioligands and PET ligands where available)

• Further reading lists

7

Detailed annotation for selected targets

Data are collected and reviewed by NC-IUPHAR subcommittees and individual experts:

• Gene and protein information• IUPHAR nomenclature and synonyms • Extensive pharmacology: agonist, antagonist and allosteric

regulator affinities, ion channel blockers, enzyme/transporter inhibitors and substrates

• Signal transduction mechanisms; Tissue distribution• Functional assays; Physiological functions• Mouse gene knockout phenotypes• Clinically-relevant mutations and pathophysiology• Gene expression changes in disease; Biologically significant

variants

8

Other features• Extensively referenced and linked to primary literature in

PubMed• Focus is on human data but where species differences

exist or literature data unavailable other species are given• Linked to corresponding entries in other resources, e.g.

UniProt, Ensembl, Entrez Gene, KEGG, OMIM, ChEMBL• Ligand information including structure, peptide

sequences, clinical data and nomenclature, linked up to chemistry resources including PubChem

25

Database search functionality• Quick search box at the top of every page with

autocomplete for target, family and ligand names

• Advanced searches are available on the Target Search and Ligand Search pages

26

Target search tools• Search by name or keyword, identifier (e.g. UniProtKB

accession) or reference (e.g. PubMed id)

27

Ligand search tools• Search by name, identifier (e.g. PubChem CID, InChI) or

structure (exact match, similarity, substructure, SMARTS)

28

Advanced search by keyword• Keyword searches, for example by disease name, can

facilitate retrieval of associated ligands and targets

A search for “Alzheimer’s disease” returns implicated targets and ligands tested in clinical trials
