Also provided are compositions comprising a plurality of polymer-polypeptide conjugates, said polymer-polypeptide conjugate comprising a polypeptide covalently attached to at least one polymer through an epsilon amino group of a Lysine or a Histidine found on the polypeptide and said conjugates containing less than 5% of the polymer-polypeptide conjugates having a polymer attached to the N-terminal of the polypeptide; and polymer target conjugates comprising a target moiety selected from the group consisting of polypeptides, proteins and the like having at least one polymer attached thereto at a site which is not the N-terminal of the target.

  • Patent number: 8642737
    Abstract: The invention relates to materials and methods of conjugating a water soluble polymer to an oxidized carbohydrate moiety of a therapeutic protein comprising contacting the oxidized carbohydrate moiety with an activated water soluble polymer under conditions that allow conjugation. More specifically, the present invention relates to the aforementioned materials and methods wherein the water soluble polymer contains an active aminooxy group and wherein an oxime or hydrazone linkage is formed between the oxidized carbohydrate moiety and the active aminooxy group on the water soluble polymer, and wherein the conjugation is carried out in the presence of a nucleophilic catalyst.

  • Publication number: 20140031530
    Abstract: This invention provides long-acting, superactive analogs of glycoprotein hormones demonstrating enhanced bioactivity both in vitro and in vivo as compared to wild type counterparts. The analogs are particularly useful for treating subjects showing low receptor expression or poor receptor responsiveness, and for the treatment of any condition associated with glycoprotein hormone activity.
