    摘要： The present invention provides a process for identifying compounds which bind to a specific target molecule. The process comprises the steps of: a) generating a first T.sub.2 - or diffusion-filtered proton spectrum of one or a mixture of chemical compounds; b) exposing one or a mixture of chemical compounds to the target molecule; c) generating a second T.sub.2 - or diffusion-filtered proton spectrum of one or a mixture of chemical compounds that has been exposed the target molecule in step (b); and d) comparing said first and second T.sub.2 - or diffusion-filtered proton spectra to determine differences between said first and said second spectra, the differences identifying the presence of one or more compounds that are ligands which have bound to the target molecule.

    摘要： The present invention provides a process for identifying compounds which bind to a specific target molecule. The process includes the steps of a) generating a first two-dimensional .sup.15 N/.sup.1 H NMR correlation spectrum of a .sup.15 N-labeled target molecule; b) exposing the labeled target molecule to one or a mixture of chemical compounds; c) generating a second two-dimensional .sup.15 N/.sup.1 H NMR correlation spectrum of the labeled target molecule that has been exposed to one or a mixture of compounds in step (b); and d) comparing said first and second two-dimensional .sup.15 N/.sup.1 H NMR correlation spectra to determine differences between said first and said second spectra, the differences identifying the presence of one or more compounds that are ligands which have bound to the target molecule.

    摘要： 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.
