Biological effects … See more Chemical similarity is often described as an inverse of a measure of distance in descriptor space. Examples for inverse distance measures are molecule kernels, that measure the structural similarity of chemical compounds. See more The similarity-based virtual screening (a kind of ligand-based virtual screening) assumes that all compounds in a database that are similar to a query compound have similar biological activity. Although this hypothesis is not always valid, quite often the set of retrieved … See more • Bender, Andreas; Glen, Robert C. (2004). "Molecular similarity: a key technique in molecular informatics".
