  • Patent number: 4401662
    Abstract: Oligosaccharides obtainable from heparin including heparinic constituents of molecular weights ranging from 2000 to 50,000. Said fractions have a Yin-Wessler titer and a USP titer in a ratio of at least 30. They consist of chains constituted by no more than 8 saccharidic moities. They possess a strong antithrombotic activity and are then useful as antithrombotic drugs.
    Type: Grant
    Filed: October 6, 1980
    Date of Patent: August 30, 1983
    Assignee: Choay, S.A.
    Inventors: Jean-Claude Lormeau, Jean Choay, Maurice Petitou
  • Patent number: 4401758
    Abstract: Oligosaccharides obtainable from heparin including heparinic constituents of molecular weights ranging from 2000 to 50,000. Said fractions have a Yin-Wessler titer and a USP titer in a ratio of at least 30.They consist of chains substituted by no more than 8 saccharidic moities. They possess a strong antithrombotic activity and are then useful as antithrombotic drugs.
    Type: Grant

    Inventors: Jean-Claude Lormeau, Jean Choay, Maurice Petitou
  • Patent number: 4177262
    Abstract: The invention pertains to water soluble compositions having plasminogen activity capable of activation to plasmin formed of a mixture of different plasminogen compounds, among which native plasminogen and lysyl-plasminogen. It further concerns such compositions freed from the native plasminogen. They are obtained by the selective fixation of the other plasminogen compounds on fibrin. These compositions are useful for the production of pharmaceutical compositions.
    Type: Grant

    Date of Patent: December 4, 1979
    Assignee: Choay S.A.
    Inventors: Jean-Claude Lormeau, Jean Choay, Jean Goulay
  • Patent number: 4115551
    Abstract: The placental pulps notably of human origin are separated from the placental blood, which is removed, and the pulps are macerated in a solution at a pH comprised between 5 and 10, e.g. isotonic NaCl solution, preferably at neutral pH, in the presence of an amino-acid inhibitor of plasminogen activation, at a molar concentration comprised between about 0.001 and 0.1 M, preferably of the order of 0.035 M. The pulps are removed and the solution containing the compounds of the plasminogen type is recovered. Preferred inhibitors are L-lysine, epsilon aminocaproic acid, and trans-4 aminomethyl cyclohexane carboxylic acid.
