  The present invention provides, in one aspect, bifunctional compounds that can be used to promote or enhance degradation of certain circulating proteins. In another aspect, the present invention provides bifunctional compounds that can be used to promote or enhance degradation of certain autoantibodies. In certain embodiments, treatment or management of a disease and/or disorder requires degradation, removal, or reduction in concentration of the circulating protein or the autoantibody in the subject. Thus, in certain embodiments, administration of a compound of the invention to the subject removes or reduces the circulation concentration of the circulating protein or the autoantibody, thus treating, ameliorating, or preventing the disease and/or disorder. In certain embodiments, the circulating protein is TNF.

  本发明在一个方面提供了可以用来促进或增强降解某些循环蛋白的双功能化合物。在另一个方面，本发明提供了可以用来促进或增强降解某些自身抗体的双功能化合物。在某些实施方式中，治疗或管理疾病和/或疾病需要降解、去除或减少受试者体内循环蛋白或自身抗体的浓度。因此，在某些实施方式中，将本发明的化合物给予受试者可去除或减少循环蛋白或自身抗体的循环浓度，从而治疗、改善或预防疾病和/或疾病。在某些实施方式中，循环蛋白是TNF。

  The asialoglycoprotein receptor (ASGPR) is a high-capacity galactose-binding receptor expressed on hepatocytes that binds its native substrates with low affinity. More potent ligands are of interest for hepatic delivery of therapeutic agents. We report several classes of galactosyl analogues with varied substitution at the anomeric, C2-, C5-, and C6-positions. Significant increases in binding affinity were noted for several trifluoromethyl-acetamide derivatives without covalent attachment to the protein. A variety of new ligands were obtained with affinity for ASGPR as good as or better than that of the parent N-acetylgalactosamine, showing that modification on either side of the key C3,C4-diol moiety is well tolerated, consistent with previous models of a shallow binding pocket. The galactosyl pyranose motif therefore offers many opportunities for the attachment of other functional units or payloads while retaining low-micromolar or better affinity for the ASGPR.
• Resin-Supported Catalysts for CuAAC Click Reactions in Aqueous or Organic Solvents

  The copper-catalyzed azide-alkyne cycloaddition click reaction is a valuable process for the synthesis of libraries of drug candidates, derivatized polymers and materials, and a wide variety of other functional molecules. In some circumstances, the removal of the copper catalyst is both necessary and inconvenient. We describe here two immobilized forms of a Cu-binding ligand that has been shown to accelerate triazole formation under many different conditions, using different resin supports that are appropriate for aqueous or organic solvents. Copper leaching from these resins was modest, allowing them to be reused in many reaction/filtration cycles without recharging with metal ion. The utility of this catalyst form was demonstrated in the convenient synthesis of 20 N-acetylgalactosamine derivatives for biological testing.
