The present disclosure provides conjugates that comprise an insulin molecule conjugated via a conjugate framework to two or more separate ligands that each include a saccharide, wherein the framework, ligand, saccharide and insulin molecule optionally comprise a fatty chain (e.g., a C8-30 fatty chain), wherein when said insulin molecule is conjugated both to a C8-30 fatty chain and one or more separate ligands that each include a saccharide, said C8-30 fatty chain is linked to insulin molecule only, and wherein when the framework or ligand comprises a fatty chain the insulin molecule is conjugated to two or more separate ligands. In certain embodiments, a conjugate is characterized in that, when the conjugate is administered to a mammal, at least one pharmacokinetic (PK) and/or pharmacodynamic (PD) property of the conjugate is sensitive to serum concentration of a second saccharide. In certain embodiments, a conjugate is also characterized by having a protracted PK profile. Exemplary conjugates and sustained release formulations are provided in addition to methods of use and preparation.
high affinity for glucose, while RAW264.7 for glucose, galactose, mannose, and fucose. A similar cell-monosaccharide affinity was microscopically observed when the cells were mixed with monosaccharide-LNP conjugates and rinsed, in which the high affinity LNP probes luminesced on the cells. The high affinity monosaccharide-LNPs showed greater photodamaging effects than the unmodified LNP toward the corresponding

An insulin conjugate comprising or consisting of a tri-valent sugar cluster is described. In particular aspects, the insulin conjugate displays 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.

The present invention relates to fucose- and mannose-derived glycomimetics and their general use in prophylaxis or treatment of Pseudomonas aeruginosa infections including respiratory tract infections, urinary tract infections, nosocomial infections and chronic wound infections in a patient encompassing a patient suffering already from cystic fibrosis. Said glycomimetics are inhibitors of Pseudomonas aeruginosa lectin LecB.
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.
