BitterDB is a free repository of bitter molecules. It contains information on compounds that were documented to taste bitter to humans or to activate bitter taste receptors in-vitro.

Information about activation of human bitter taste receptors by bitter molecules can be found in BitterDB as described in the above paper, and for example by using this link: http://bitterdb.agri.huji.ac.il/bitterdb/dbbitter.php#receptorBrowseWe are grateful to the authors for allowing us to incorporate the molecular structrues of this database in ZINC.
We assess the chemical diversity of a subset by clustering the molecules. First, we sort ligands by increasing molecular weight. Then, we use the SUBSET 1.0 algorithm ( Voigt JH, Bienfait B, Wang S, Nicklaus MC. JCICS, 2001, 41, 702-12) to progressively select compounds that differ from those previously selected by at least the Tanimoto cutoff, using ChemAxon default fingerprints. The resulting representatives have two interesting properties:
|Tanimoto Cutoff Level||60%||70%||80%||90%||100%|
|Number of Representatives||216||301||363||436||686|
We compute the physical properties of each molecule in the subset, and graph them below.
