  • Patent number: 6653321
    Abstract: Methods for treating conditions associated with hyperglycemia, especially Type II diabetes, with novel naphthylsulfonic acids and related compounds. These compounds, as single stereoisomers or mixtures of stereoisomers, or their pharmaceutically acceptable salts, are useful in methods of stimulating the kinase activity of the insulin receptor, enhancing the activation of the insulin receptor by insulin, and stimulating the uptake of glucose into cells. A variety of antidiabetic compounds and pharmaceutical compositions comprising the antidiabetic compounds are also disclosed.

  • Publication number: 20010046970
    Abstract: This invention provides compositions for inhibiting the binding between two cells, one expressing P- or L-selectin on the surface and the other expressing the corresponding ligand. A covalently crosslinked lipid composition is prepared having saccharides and acidic group on separate lipids. The composition is then interposed between the cells so as to inhibit binding. Inhibition can be achieved at an effective oligosaccharide concentration as low as 106 fold below that of the free saccharide. Since selectins are involved in recruiting cells to sites of injury, these composition scan be used to palliate certain inflammatory and immunological conditions.

  • Patent number: 5985852
    Abstract: This invention provides compositions for inhibiting the binding between two cells, one expressing P- or L-selectin on the surface and the other expressing the corresponding ligand. A covalently crosslinked lipid composition is prepared having saccharides and acidic group on separate lipids. The composition is then interposed between the cells so as to inhibit binding. Inhibition can be achieved at an effective oligosaccharide concentration as low as 10.sup.6 fold below that of the free saccharide. Since selectins are involved in recruiting cells to sites of injury, these composition scan be used to palliate certain inflammatory and immunological conditions.
