  • Patent number: 10723750
    Abstract: The compounds, compositions and methods provided herein antagonize, inhibit, decrease, reduce, suppress, or disrupt CD1d-mediated, iNKT cell-mediated, and/or iNKT cell TCR-mediated immune signaling. The sphingamide compounds were rationally designed based upon 3D structural considerations in relation to the structures of each of CD1d, the iNKT cell TCR, and the ternary complex CD1d-a-GalCer analog lipids-TCR. More specifically, the addition of an amide in the phytosphingosine tail of a derivative of ?-GalCer led to a non-conserved binding with CD1d, a conserved binding with the iNKT cell TCR, and an antagonist-like phenotype.

  • Publication number: 20130046087
    Abstract: The present invention relates to substituted cyclodextrin derivatives which are particularly useful intermediates for producing well-defined carboxyalkylated cyclodextrins in contrast with the poorly-defined mixtures available through prior art procedures. The present invention also relates to processes for their preparation in a limited number of steps. These well-defined carboxyalkylated cyclodextrins can be polysulfated according to procedures standard in the art and some of these polysulfates, and alkali salts thereof, have been found to exhibit biologically active properties especially for the treatment and/or prophylaxis of degenerative joint diseases (e.g. osteoarthritis) or heparin-induced thrombocytopenia, or for cartilage repair or connective tissue repair.
