Pharmacophores correspond to common chemical features associated to an affinity for a specific receptor. They explain how structurally diverses ligands can bind to a common receptor site. Emerging fragments correspond to a conjunction of chemical features associated to a class of chemicals. These two notions are very close but one (pharmacophore) is based on the definition of common characteristic associated to a class of derivatives and the second (emerging fragment) is based on the comparison of chemical datasets (normally two datasets).Polypharmacological properties are associated to all molecules interacting with biological processes. The issue is to control these properties by a specific orientation towards therapeutic targets. vs Bureau R, Pharmacophores vs Emerging fragments.
