  • Biomaterials carrying cyclodextrins having improved absorption properties and used for the progressive and delayed release of therapeutic molecules
    Patent number: 8906403
    Abstract: A method for preparing a biomaterial containing at least one bioactive molecule from a base biomaterial, comprising the following successive operations carried out on the base biomaterial: a) application of a solid mixture of: cyclodextrin(s) and/or cyclodextrin derivative(s) and/or cyclodextrin inclusion complex(es) and/or cyclodextrin derivative inclusion complex(es), at least one poly(carboxylic) acid, and optionally a catalyst; b) heating at a temperature between 100° C. and 200° C. for a period of 1 to 60 minutes; c) washing with water; d) drying, wherein at least one bioactive agent is incorporated in the biomaterial by impregnation of the biomaterial after the drying step in a concentrated solution of the bioactive agent.

  • Cyclodextrin polymers and/or cyclodextrin derivatives with complexing properties and ion-exchange properties and method for the production thereof
    Patent number: 6660804
    Abstract: The present invention concerns a process for preparing copolymers of cyclodextrin(s) and/or cyclodextrin derivative(s), characterized by the following operations: (a) preparing a solid state mixture of cyclodextrin(s) and/or cyclodextrin derivative(s) and/or inclusion complex(es) of cyclodextrin(s) and/or cyclodextrin derivative(s) and a poly(carboxylic) acid and/or a poly(carboxylic) acid anhydride or a mixture of poly(carboxylic) acid(s) and/or poly(carboxylic) acid anhydride(s), and optionally, a catalyst; and (b) heating the solid mixture to a temperature in the range 100° C. to 200° C. for a period in the range 1 min to 60 min, preferably 30 min or substantially 30 min. The present invention also concerns soluble and insoluble compounds of cyclodextrin(s) and/or cyclodextrin derivative(s) or their inclusion complexes with at least one poly(carboxylic) acid.
