  • Patent number: 5891643
    Abstract: The present invention provides a process of designing compounds which bind to a specific target molecule. The process includes the steps of a) identifying a first ligand to the target molecule using two-dimensional .sup.15 N/.sup.1 H NMR correlation spectroscopy; b) identifying a second ligand to the target molecule using two-dimensional .sup.15 N/.sup.1 H NMR correlation spectroscopy; c) forming a ternary complex by binding the first and second ligands to the target molecule; d) determining the three dimensional structure of the ternary complex and thus the spatial orientation of the first and second ligands on the target molecule; and e) linking the first and second ligands to form the drug, wherein the spatial orientation of step (d) is maintained.
