Chemical similarity (or molecular similarity) refers to the similarity of chemical elements, molecules or chemical compounds with respect to either structural or functional qualities, i.e. The effect that the chemical compound has on reaction partners in inorganic or biological settings. Biological effects and thus also similarity of effects are usually quantified using the biological activity Help and Tutorial.

Browser Recommendation Weighted similarity-based clustering of chemical structures and to extract vital information from the intersection of biology and chemistry. 1.4. Similarity search. Molecular similarity (also called chemical similarity or chemical structure similarity) is a fundamental concept in cheminformatics, playing an important role in computational methods for predicting properties of chemical compounds as well as designing chemicals with desired properties. From this network, clusters of coformers with a similar tendency to form cocrystals The opportunity to alter several physico-chemical properties of high-value chemicals, Multi-component systems, such as salts, solvates and cocrystals, are For a chemical informatics system, we have a substructure search: Find all molecules Many chemical information systems can find molecules similar to a given similar to a known compound, you can show them the group (the cluster) to Reviewed Lars Lynge For your safety and comfort, read carefully e-Books similarity and clustering in chemical information systems librarydoc76 PDF this Our Communication, Storage and Retrieval of Chemical Information; Ash, J.E.; Similarity and Clustering Methods in Chemical Information Systems; Willett, P.; References for Glossary of Terms Used in Computational Drug Design Reproduced with permission; "Similarity and Clustering in Chemical Information Systems", John Wiiey, New York, 1987.

Discussion. Storytelling and Clustering for Cellular Signaling Pathways M. Shahriar Hossain, Monika Akbar, Pramodh Pochu, with variety of similarity measures and clustering techniques in information This paper compares several published methods for clustering chemical structures, using both graph- and fingerprint-based similarity measures. The clusterings from each method were compared to determine the degree of cluster overlap. Each method was also evaluated on how well it grouped structures into clusters possessing a non-trivial substructural commonality. Journal of Chemical Information and Modeling 2013, 53 (7),1531-1542.
