  • Patent number: 7269519
    Abstract: The present invention provides a method for identifying a member of a mass-coded combinatorial library which is a ligand for biomolecule and assessing the effect of the binding of the ligand to the biomolecule. The mass-coded molecular library comprises compounds of the general formula XYn, wherein n is an integer from 2 to about 6, X is a scaffold and each Y is, independently, a peripheral moiety. The mass-coded combinatorial library is produced by reacting a scaffold precursor with a sufficient number of distant peripheral moiety precursors such that there exist at least about 250 distinct combinations of n peripheral moieties derived from the peripheral moiety precursors.

  • Patent number: 7169563
    Abstract: Methods for identifying a member of a mass-coded molecular library, which is a ligand for a biomolecule and binds to the biomolecule at the binding site of a known second ligand for the biomolecule are described. The methods includes contacting a mass-coded molecular library with a biomolecule; separating the biomolecule-ligand complexes from the unbound members of the mass-coded molecular library; contacting the biomolecule-ligand complexes with a second ligand to dissociate biomolecule-ligand complexes in which the ligand binds to the biomolecule at the binding site of the second ligand, thereby forming biomolecule-second ligand complexes and dissociated ligands; separating the dissociated ligands and biomolecule-second ligand complexes; and determining the molecular mass of each dissociated ligand.
