  • Patent number: 11046640
    Abstract: The present invention relates to novel compounds of the formula I, methods for their preparation and their use for treatment of diseases. The invention discloses the synthesis of levodopa (L-DOPA) esters by coupling polyhydroxy compounds or their derivatives to the L-DOPA carboxyl group. The synthesis allows to produce L-DOPA derivatives which are highly soluble in water as well as aqueous and biocompatible liquids and have an improved hydrolytic stability in water or aqueous and biocompatible media for an application over several days. The invention helps producing L-DOPA substances for applications in the fields of medicine, biology and medical engineering as well as in the pharmaceutical industry.

  • Publication number: 20190185416
    Abstract: It is an object of the present invention to introduce carboxylic acid-functionalities suitable for coupling into the denatonium structure by means of simple synthesis, namely the synthesis of bitter principle derivatives based on the denatonium structure according to formula 1: For example, according to the invention, lidocaine derivatives may be reacted with carboxylated benzyl halogenides. The carboxylated denatonium derivatives of the present invention are especially applied in medicine, biology, medical engineering as well as cosmetics, the pharmaceutical, chemical, and foodstuff industry.

  • Patent number: 9669111
    Abstract: The document proposes a diagnostic chewing gum for identifying the presence of inflammatory tissues in the mouth, in particular in or adjacent to the mandible, the maxilla, an implant or the teeth of a user, comprising a base material or particles (3) embedded and/or attached to the base material; an element (1, 5-7), like e.g. a releasable flavor molecule, attached to the base material and/or the particles, for the generation of a change in the chewing gum directly detectable by the user; wherein the element (1, 5-7) generates the change upon direct or indirect contact with a marker (4), e.g. a proteolytic enzyme, which is released by inflammatory tissue in response to bacterial mediators.
