  • Publication number: 20020147159
    Abstract: The present invention is directed towards a method and composition for controlled release acarbose formulations. The method and composition disclosed herein combine acarbose and a sustained release matrix. The administration of acarbose alone has been shown to be useful in the treatment of diabetes. Although the initial studies conducted herein were conducted with a delayed release formulation that allowed partial sustained release administered to stimulate sustained release, all indicators from the present invention suggest the formulation of acarbose in a sustained release formulation would have heretofore unexpected benefits. In a sustained release formulation, the ingredient(s) would be a shaped dosage unit having a sustained and regular release of acarbose throughout the small intestine where carbohydrates as a simple sugar are absorbed.

    Abstract: A new class of N-linked Lewis and LacNAc analogs of are synthesized and shown to be effective inhibitors of human fucosyltransferases. In a high yielding reaction sequence the glucosamine derivative 1 was transformed to the 3-azido-2,3-dideoxy sugar 2e under excellent stereocontrol. The LacNAc analog 4d was synthesized as a single isomer in three steps starting from 2e. In a one pot procedure iminocyclitol 5 was transformed into aldehyde 6 and successfully used for reductive amination with 4c and 2f yielding trisaccharide 8a, and disaccharide 7a.

  • Patent number: 6224891
    Abstract: This invention relates to the treatment of diarrhea and related conditions caused by pathogenic E. coli infection. More specifically, this invention is drawn to the unexpected discovery that by administering a composition which binds and removes the shiga like toxins (SLT) produced by pathogenic E. coli whenever an antibiotic is administered, improved treatment is provided. Novel compositions containing both antibiotic and toxin binding composition and methods of treatment which use simultaneous administration toxin binding composition whenever antibiotic is administered are provided. These compositions and methods kill the enteric E. coli organisms which produce the conditions and neutralize the SLT produced by the organisms and/or released from the organisms when they are killed. Thus, these compositions and methods are better able to ameliorate the symptoms of the infection and inhibit progression of this infection into hemolytic uremic syndrome (HUS) than conventional treatment.

  • Patent number: 6197568
    Abstract: Methods and compositions for the isolation, diagnosis and treatment of microorganisms such as flaviviruses and other hemorrhagic fever viruses are based on the sulfated polyanion-dependent interaction of flaviviruses and hemorrhagic fever viruses, in particular dengue virus, with target cells. The cellular receptors targeted by these viruses have been identified as sulfated polyanionic glycoproteins, that include highly sulfated heparan sulfate glycosaminoglycans for some target cell types, and as a sulfated mucin on vascular endothelium. Compounds such as heparin, highly sulfated heparan sulfate, and synthetic polyanions such as Suramin, inhibit the interaction between the microorganisms and target cells, thereby disrupting the infective process.
