Ernst Truscheit has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • .alpha.-Glucosidase inhibiting 2-hydroxymethyl-3,4,5-trihydroxy-piperidines
    Patent number: 4328233
    Abstract: The invention relates to 2-hydroxymethyl-3,4,5-trihydroxy-6-substituted-piperidines and methods for their preparation. The invention also includes compositions containing said 2-hydroxymethyl-3,4,5-trihydroxy-6-substituted-piperidines and the use of said compounds and compositions for influencing carbohydrate metabolism and fat metabolism and for use in animal nutrition as feed additives.
    Type: Grant
    Filed: October 29, 1979
    Date of Patent: May 4, 1982
    Assignee: Bayer Aktiengesellschaft
    Inventors: Horst Boshagen, Rudiger Sitt, Ernst Truscheit
  • Derivatives, having an inhibitory action against protease and an antiphlogistic action, of the trypsin-kallikrein inhibitor obtained from cattle organs (BPTI), their preparation and their use as medicaments
    Patent number: 4153687
    Abstract: The invention provides derivatives of kallikrein-trypsin inhibitor (BPTI) in which one or both of the 10- or 21-tyrosine residues are linked, in the o-position relative to the phenolic hydroxyl group, to an aptionally substituted carbocyclic or heterocyclic aromatic radical via an azo group and the other if only one of the said residues is substituted is either unsubstituted or carries a nitro group or an amino group in the o-position relative to the phenolic hydroxyl group.The azo-BPTI derivatives of the invention can be used, as medicaments for the therapy of diseases which are caused either by over-production of proteases as a result of increased liberation from the zymogens or of release during cell decomposition or by a deficiency or lack of natural indogenous inhibitors of these enzymes in organs and tissue fluids.
    Type: Grant
    Filed: November 2, 1977
    Date of Patent: May 8, 1979
    Assignee: Bayer Aktiengesellschaft
    Inventors: Eugen Schnabel, Gerd Reinhardt, Horst D. Schlumberger, Ernst Truscheit, Harold Tschesche
  • Process for the preparation of immunopotentiating agents from components of yeast cell wall material
    Patent number: 4138479
    Abstract: A water soluble immunopotentiating agent is derived from yeast cell wall material, including mechanically disrupted yeast cell walls, proteolyzed yeast cell wall material and carbohydrate-protein complexes found in yeast cell wall material, through extraction with a water-phenol mixture. The water soluble agent is isolated from the water phase and can be further purified, as through dialysis, to remover low molecular weight components.
    Type: Grant
    Filed: September 12, 1977
    Date of Patent: February 6, 1979
    Assignee: Bayer Aktiengesellschaft
    Inventors: Ernst Truscheit, Robert Bierling, Horst D. Schlumberger, Herbert F. Oettgen
  • Deamino derivatives of the kallikrein-trypsin inhibitor
    Patent number: 4118481
    Abstract: A demaino kallikrein-trypsin inhibitor obtained from cattle organs is characterized by (a) 0 to 3 lysine residues and/or 3 to 6 arginine residues and/or 1 to 4 tyrosine residues; (b) the 10- and/or 21-tyrosine residues being unsubstituted or substituted by at least one nitro, nitroso or amino in the ortho position relative to the phenolic hydroxy group; and (c) having protease inhibitory activity of BPTI and elastase inhibition activity.
