Polysaccharides Patents (Class 536/123.1)
  • Patent number: 8227449
    Abstract: Glycosaminoglycans derived from K5 polysaccharide having high anticoagulant and antithrombotic activity and useful for the control of coagulation and as antithrombotic agents are obtained starting from an optionally purified K5 polysaccharide by a process comprising the steps of N-deacetylation/N-sulfation, C5 epimerization, O-oversulfation, selective O-desulfation, 6-O-sulfation, N-sulfation, and optional depolymerization, in which said epimerization is performed with the use of the enzyme glucoronosyl C5 epimerase in solution or in immobilized form in the presence of divalent cations. New, particularly interesting antithrombin compounds are obtained by controlling the reaction time in the selective O-desulfation step and submitting the product obtained at the end of the final N-sulfation step to depolymerization.

Results indicated that the inhibition of H+ K+ ATPase activity which causes acidity in the lumen of the stomach, also exhibited better H+K+ ATPase inhibition (PPI) at the IC50 of 27.2 ?g (GRPP) and 16.5 ?g GAE (AOX) respectively than the known antiulcer proton pump blocker Lansoprazole (19.3 ?g). Further the antioxidant activity in antioxidant extract (GRAOX) by various assay systems was examined such as Reducing power, Free radical scavenging (FRS), DNA and cytoprotection systems etc. GRAOX exhibited concentration dependent reducing power ability at 5-25 ?g equivalent of phenol. FRS activity with IC50 of 6.8 ?g equivalent of phenol etc. At 0.

  • Patent number: 8137681
    Abstract: The present invention relates to the field of vaccines, and in particular vaccines comprising antigens of low isoelectric point at pH 7.0, in particular the capsular polysaccharide or oligosaccharide of H. influenzae B (PRP). Immunogenic compositions and methods of making such compositions are presented in which the PRP is surprisingly protected from immune interference by adding a polyanionic polymer (such as PLG—poly-L-glutamic acid) to the composition.

  • Publication number: 20120058054
    Abstract: Disclosed are a gadolinium complex formed by coordination of gadolinium to the diethylenetriaminepentaacetic acid dianhydride (DTPA) moiety of a pullulan-DTPA conjugate formed by an ester bond between pullulan and DTPA, a preparation method thereof, an MRI contrast composition comprising the complex, and a method of providing information for diagnosis of disease using the complex as an MRI contrast agent. The pullulan-DTPA-Gd complex has a long in vivo half-life, low toxicity, and high MRI signal intensity resulting in clear MRI images, compared to prior gadolinium complexes, indicating that it is advantageously used as an MRI contrast agent. In addition, it is possible to obtain MRI images allowing one to differentiate between diseased liver tissue and normal liver tissue, indicating that it is used as an MRI contrast agent for the liver.
