Patent

CA 2561873

The present invention provides algin oligosaccharides having polymerized degree of 2-22 and the derivatives thereof, such algin oligosaccharides are made of mannuronic acid bonded by .prop.-1,4 glycosidic bond. The derivatives which the reduced terminal in position-1 is carboxyl radical can be obtained by oxidation. The invention also provides the manufacture of algin oligosaccharides and the derivatives thereof, which includes the alginate solution in water reacts in the reactor under the condition of high press, 100- 120~C, pH2-6, for 2-6 hours, after the reaction completed, its pH value was adjusted to 7. The result oligosaccharides are oxidated in presence of the oxidant, and then produces the oxidated products. The algin oligosaccharides and the derivatives thereof of the invention can be used in the manufacture of medicaments for preventing Alzheimer~s dementia.

L'invention concerne des oligosaccharides d'algine possédant un degré polymérisé compris entre 2 et 22 et des dérivés de ceux-ci, ces oligosaccharides d'algine étant fabriqués à partir d'acide mannuronique par une liaison .alpha.-1,4 glycosidique. Les dérivés dont le terminal réduit en position 1 consiste en un radical de carboxyle peut être obtenu par oxydation. L'invention concerne également la fabrication d'oligosaccharides d'algine et des dérivés de ceux-ci, par mise en réaction de la solution d'alginate dans de l'eau dans le réacteur dans des conditions de haute pression, 100-120 ·C, pH2-6, durant 2 à 6 heures, après réalisation de la réaction, la valeur du pH est ajustée à 7. Les oligosaccharides obtenus sont oxydés en présence de l'oxydant, puis produisent les produits oxydés. Les oligosaccharides d'algine et les dérivés de ceux-ci peuvent être utilisés dans la fabrication de médicaments destinés à prévenir la maladie d'Alzheimer et le diabète sucré.
