The ligand details page has been expanded to include a description of the ligand, where available. A 2D depiction of the ligand chemical structure is shown, together with synonyms and identifiers from PubChem (43), Guide to Pharmacology (44), ChEMBL and DrugCentral. Activity values are displayed in collapsible panels, and sorted by target. By clicking on a target header, users are able to examine activity values for that ligand on the selected target. Activity type, value and mechanism of action are shown, in addition to reference publication for each activity, allowing users to directly view the source. Figure 8 illustrates this page display.
