Analogues of the tumor-associated gangliosides GM(3) and GM(2) containing terminal S-linked neuraminic acid residues and an amino terminated, truncated ceramide homologue have been synthesized and conjugated to a protein. The synthesis involved coupling of a S-linked sialyl alpha(2-->3) galactose disaccharide with a glucosyl sphingosine analogue, followed by elaboration and deprotection to give amino-terminated
Bridged isocytosine-adenosine compounds: Synthesis and antibacterial evaluation

In an approach to novel antibacterial agents, we synthesized a series of 5-nitrosoisocytosines in which a 6-alkylamino substituent is bridged, through an amide linkage at the terminus of the alkyl chain, to the 5′-position of a 5′-deoxyadenosine moiety. A corresponding series of 5-nitro analogues were also prepared. None of the bridgedcompounds showed significant antibacterial activity.

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.

biological processes of high pharmaceutical interest. Multivalent carbohydrate conjugates (glycoclusters) have been frequently used to study and manipulate these interactions. In this report, we present the synthesis of trimeric glucose and mannose conjugates that have been assembled with an AB3 scaffold based on adamantane. Several neoglycoconjugates bearing three carbohydrates have been synthesized
