Under ‘Search’, users may search DrugBank by Chemical Structure (via drawn structure images, Figure 1B), Molecular Weight (including MW ranges), Drug/Food Interactions, Target (protein) Sequences, Pharmaco-omics and Advanced Text searches (by specifying predicates and inclusion fields, Figure 1C and D). A separate search option is available for eight different spectral/chromatographic searches (MS, MS/MS, GC/MS, 1D NMR, 2D NMR, CCS, RI and RT). New tabs have been added to the menu bar, including ‘Interaction Checker’ to support drug–drug and food-drug interaction queries (described later in this manuscript) and ‘Products,’ which covers licensable DrugBank products available primarily to the pharmaceutical industry. The ‘About’ dropdown contains FAQs and guidelines on how to cite DrugBank, as well as general information about the Wishart research group at the University of Alberta.
