Description:
This assay details affinity data for agonists at human 5-Hydroxytryptamine receptor 5-ht5a, as described in the published literature. Where possible the data described are at transfected receptors expressed in cell lines and the ligands described are those that are potent, selective, endogenous, or those used as prescription medications.
Protocol
The International Union of Basic and Clinical Pharmacology Database (IUPHAR-DB) uses expert subcommittees to collate peer-reviewed information from the published literature regarding individual receptors or ion channels, and describes the pharmacology, genetics, function and anatomy of each receptor. Its pages provide a richly curated overview of the biology of each receptor and can be found by following the external link to the IUPHAR-DB website.
Comment
The data collected focuses on ligands at human receptors. Data are provided at rat or mouse receptors where there are significant species differences, or where data are not yet available at human receptors.
Information on individual experimental protocols can be found in the primary references listed for each ligand.
Affinity data are expressed as pKi [-log(Ki)], pKd [-log(Kd)], pIC50 [-log(IC50)], pEC50 [-log(EC50)], pKB [-log(KB)] or as a micromolar concentration range. In most cases the original concentration can be found in the primary reference.
