  • Publication number: 20040077590
    Abstract: The subject invention relates to monovalent oligosaccharides and their use, for example, in the treatment and prevention of mammalian disease caused by HIV-1 virus infections. In particular, the oligosaccharides globotriose and lactose may be used alone or in combination to competitively inhibit the formation of the viral fusion complex that occurs upon infection.

  • Publication number: 20030236217
    Abstract: Disclosed are compositions and methods for alleviating mucositis, wherein said methods and compositions are directed to the formulation or use of selected nucleoside derivatives, especially ADP-ribose, that conform to the general formula A-B-X and pharmaceutically acceptable salts thereof, wherein “A” is a nucleoside structure selected from adenosine, guanosine, and uridine; “B” is a diphosphate linkage attached to the 5′ carbon of the nucleoside ribose moiety; and “X” is attached to B an is a moiety selected from hydrogen, furanose, or pyranose. Also disclosed are pharmaceuticals and nutritional liquid embodiments thereof, including lozenges, mouthwashes, or other product forms that effectively coat the oral, laryngeal or other mucosal areas.

  • Patent number: 6596707
    Abstract: The subject invention relates to monovalent oligosaccharides and their use, for example, in the treatment and prevention of mammalian disease caused by infection with Shiga toxin (ST) or Shiga-like toxin (SHL). In particular, the trisaccharide globotriose (i.e., galactose &agr;1,4 galactose &bgr;1,4 glucose) may be used to competitively inhibit binding of the toxins to their cellular targets.

  • Patent number: 5492899
    Abstract: An improved enteral nutritional formula containing ribo-nucleotide equivalents (RNA, mono-, di- and triphosphate nucleotides, nucleosides and adjuncts such as activated sugars) at a level of at least 10 mg/100 Kcal (kilocalorie) of formula is disclosed. The formula comprises carbohydrates, lipids, proteins, vitamins and minerals and four (4) ribo-nucleotide equivalents at specific levels and ratios. The invention also discloses novel methods of production and analytical techniques. An infant formula containing cytidine nucleotide equivalents in the range of 29 to 39 mg/liter of formula, uridine nucleotide equivalents in the range of 15 to 20 mg/liter of formula, adenosine nucleotide equivalents in the range of 10 to 15 mg/liter of formula and guanosine nucleotide equivalents in the range of 14 to 20 mg/liter of formula provides a dietary formula that enhances the immune system and alleviates diarrhea.
