BindingDB provides a range of tools to support these and other applications. Many are accessed via the left-hand menu available on most of our webpages (Figure ). For example, one can readily access all data available for a given protein target by browsing target names () or UniProt IDs (). For each target, a tab-separated value (TSV) file with SMILES and InChI 50 strings as well as SDfiles with 2D or computed 3D structures, is available for immediate download. Alternatively, one may view the data online in a tabular format, which has been described previously . One can view or download a prepared file of all data from a given article ( , ) or patent ( , ). Integrated ChemAxon tools allow chemically aware searching within BindingDB, optionally in conjunction with filtering by affinity range, existence of the compound in the PDB, and/or in relation to any selection of protein targets (Figure ).
