  • Patent number: 8633157
    Abstract: The present invention provides conjugates between erythropoietin and PEG moieties. The conjugates are linked via an intact glycosyl linking group interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from glycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar moiety onto a glycosyl residue on the peptide. Also provided are methods for preparing the conjugates, methods for treating various disease conditions with the conjugates, and pharmaceutical formulations including the conjugates.

  • Patent number: 8361961
    Abstract: The present invention provides polypeptides that include an O-linked glycosylation site that is not present in the wild-type peptide. The polypeptides of the invention include glycoconjugates in which a species such as a water-soluble polymer, a therapeutic agent of a biomolecule is covalently linked through an intact O-linked glycosyl residue to the polypeptide. Also provided are methods of making the peptides of the invention and methods, pharmaceutical compositions containing the peptides and methods of treating, ameliorating or preventing diseased in mammals by administering an amount of a peptide of the invention sufficient to achieve the desired response.

  • Patent number: 8268967
    Abstract: The present invention provides IFN-? conjugates including IFN-? peptides and modifying groups such as PEG moieties. The IFN-? peptide and modifying group are linked via an intact glycosyl linking group interposed between and covalently attached to the IFN-? peptide and the modifying group. The IFN-? conjugates are formed from glycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar onto an amino acid or a glycosyl residue on the IFN-? peptide. Also provided are methods for preparing the IFN-? conjugates, methods for treating various disease conditions with the IFN-? conjugates, and pharmaceutical formulations including the IFN-? conjugates.

  • Publication number: 20120016050
    Abstract: Urethane acrylate oligomers, suitable for use in coatings and like formulations, prepared by capping polyols having hydroxyl functionality (fOH) equal to or greater than 4, using 2-isocyanatoethyl acrylate or 2-isocyanatoethyl methacrylate, thereby avoiding the gelation that normally occurs in attempting to prepare urethane acrylates with high/OH polyols by reaction with diisocyanates. Reaction of low molecular weight polyols, containing two or three hydroxyl groups, with mono isocyanate(meth)acrylate monomers produces useful, low viscosity urethane (meth)acrylate oligomers. Specifically, capping of a mole of 2,2-dihydroxymethyl butanoic acid by two moles of 2-isocyanatoethyl acrylate molecules leads to the formation of radiation curable water-soluble liquid monomers that are transparent and soluble in water. Oligomers obtained by capping with 2-isocyanatoethyl acrylate demonstrate enhanced adhesion to glass and stainless steel.

  • Patent number: 7956032
    Abstract: The present invention provides conjugates between Granulocyte Colony Stimulating Factor and PEG moieties. The conjugates are linked via an intact glycosyl linking group that is interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from both glycosylated and unglycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar moiety onto either an amino acid or glycosyl residue on the peptide. Also provided are pharmaceutical formulations including the conjugates. Methods for preparing the conjugates are also within the scope of the invention.
