Adaptable Synthesis of C-Glycosidic Multivalent Carbohydrates and Succinamide-Linked Derivatization
摘要:
A modular approach to the synthesis of trivalent C-glycosidic carbohydrates is described. The approach is illustrated employing carboxylate-terminated C-glycosidic D-mannose, D-glucose, and D-galactose derivatives with different length C1-linked spacer units and also core units with different length linker units attached. The central core scaffold is additionally functionalized via a succinamide-based, conjugatable linker unit, exemplified in an extended multivalent derivative [31] and a pyrene-bearing fluorsecent-labeled tris-C-mannosyl conjugate [33].
Insulin conjugates comprising an insulin molecule covalently attached to at least one bi-dentate linker having two arms, each arm independently attached to a ligand comprising a saccharide and wherein the saccharide for at least one ligand of the linker is fucose are disclosed. The insulin conjugates display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule such as Con A.

Insulin conjugates comprising an insulin analog molecule covalently attached to at least one bi-dentate linker having two arms, each arm independently attached to a ligand comprising a saccharide and wherein the saccharide for at least one ligand of the linker is fucose are disclosed. The insulin conjugates display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule such as Con A.
