... is an extremely important concept for defining patterns in molecules. Unfortunately the SMARTS-language is quite complex and the description of a pattern easily becomes quite complex. Here we introduce two tools developed by Karen Schomburg and Lars Wetzer at the Center for Bioinformatics at the University of Hamburg that make life easier when working with SMARTS. Temporary licenses are granted for free.
As examples see below a number of patterns illustrating the SMARTSviewer visualization concept along with its dynamic legend, which describes each distinct atom and bond in natural language. For more examples including the so-called Pan Assay Interference Compounds (PAINS) patterns please visit the gallery website of our collaborators.
SMARTSeditor is an interactive GUI application that lets you draw substructure patterns. Jump-starting from a molecule you may develop a SMARTS in a quite intuitive fashion by editing the topology and properties. Using pre-defined patterns for common functional groups lets you quickly reach your goal. SMARTSeditor supports recursions, allowing you to go to any level of complexity without getting lost.
