Glycosphingolipids (GSLs) bearing α-glucose (α-Glc) that preferentially stimulate human invariant NKT (iNKT) cells are provided. GSLs with α-glucose (α-Glc) that exhibit stronger induction in humans (but weaker in mice) of cytokines and chemokines and expansion and/or activation of immune cells than those with α-galactose (α-Gal) are disclosed. GSLs bearing α-glucose (α-Glc) and derivatives of α-Glc with F at the 4 and/or 6 positions are provided. Methods for iNKT-independent induction of chemokines by the GSL with α-Glc and derivatives thereof are disclosed. Methods for immune stimulation in humans using GSLs with α-Glc and derivatives thereof are provided.

Readily available hydrophilic and small organofluorine moieties were condensed via “click chemistry” to generate nonionic hydrophilic fluorinated molecules with unique .sup.19F MR signatures. These were used to fabricate stable liposome formulations for imaging various tissue types. This approach was tailored to exploit the broad spectrum of organic .sup.19F molecular species and to generate probes with distinct .sup.19F MRI signatures for simultaneous assessment of multiple molecular targets within the same target volume.

The present invention relates to synthetic saccharides of general formula (I) that are related to Streptococcus pneumoniae serotype 8 capsular polysaccharide, conjugates thereof and the use of said saccharides and conjugates for raising a protective immune response in a human and/or animal host. Furthermore, the synthetic saccharide structures of general formula (I) are useful as marker in immunological assays for detection of antibodies against Streptococcus pneumoniae bacteria.

Provided are macrolide compounds for the treatment of infectious diseases. The macrolides disclosed herein include 14-membered ketolides and 14-15-membered azaketolides, and may comprise modified sugars which are desosamine analogues. The disclosed macrolides may have a bicyclic structure. Also provided are pharmaceutical compositions and methods of treating infectious diseases, and in particular, disease which results from Gram negative bacteria using the disclosed macrolides. This disclosure additionally provides methods of preparing the macrolides by a strategy that enables late-stage modification of the 6′-position of the sugar moiety, thereby allowing facile access to previously difficult-to-make macrolide compounds.
