  • Publication number: 20140179542
    Abstract: The present invention is directed to novel methods for rapidly and unambiguously identifying small organic molecule ligands for binding to biological target molecules. Small organic molecule ligands identified according to the methods of the present invention may find use, for example, as novel therapeutic drug lead compounds, enzyme inhibitors, labeling compounds, diagnostic reagents, affinity reagents for protein purification, and the like. Also presented are novel methods for identifying high affinity binding ligands for a biological target molecule of interest, wherein those methods comprise linking two or more small organic molecule ligands previously identified as being capable of binding to the biological target molecule of interest. Biological target molecules include, for example, polypeptides, nucleic acids, carbohydrates, nucleoproteins, glycoproteins, glycolipids and lipoproteins.

  • Publication number: 20080261831
    Abstract: The invention relates to variants of Target Biological Molecules (TBMs), such as proteins, peptides and other amino acid sequences that are modified to include cysteine residues at predetermined positions within the TBM. The position of amino acid residues within the TBM that are modified to be cysteine residues is selected for its proximity to ligand binding sites within the TBM. Once an amino acid residue, or the DNA encoding the residue, is modified to cysteine, the TBM linked to potential binding ligands by forming a covalent bond through the cysteine thiol (—SH) reactive group of the variant.
