PPI Curation Search for Known PPI Data

This search allows users to search known PPI inhibitors by chemical structure (SMILES or SMARTS) and chemical drawing. The Chemical Draw function allows users to draw any chemical structures and then find similar known PPI inhibitors. The collection of images of ring structures frequently found in known PPI inhibitor data collected from public databases is shown as a referecne for searching.
