Scaffold hopping is the replacement of part of a drug molecule with another, whilst retaining the features of the molecule most important for protein binding in their proper geometrical arrangement to interact with the receptor. This technique, particularly when carried out computationally on a protein-ligand crystal structure, is very popular with drug designers. It is used to develop molecules with more desirable physical properties, which escape existing patent coverage, or which may be easier to synthesize.
