  • SURFACE ACTIVE PROTEINS AS EXCIPIENTS IN SOLID PHARMACEUTICAL FORMULATIONS
    Publication number: 20110268792
    Abstract: The invention relates to a use of surface active hydrophobins for applications in pharmaceutical technology, in particular as excipients for galenic use. Provided is a method for either admixture of hydrophobins to galenic compositions or for treating the surface of pharmaceutical forms with a hydrophobin-containing solution to modify the pharmaceutical properties of the galenic form. In a preferred embodiment of the invention hydrophobins are used to improve the properties of a pharmaceutical composition, e.g. to act as a surfactant or to increase resistance to disintegration of the galenic forms to achieve a retarded drug release. The galenic form to be modified by the use of surface active proteins as excipients can be capsules, tablets, pills, microparticles, vesicles, and suppositories, although further galenic forms are envisioned.

  • COUMESTAN-LIKE ANTIOXIDANTS AND UV ABSORBANTS
    Publication number: 20100330009
    Abstract: The present invention relates to derivatives of the 1H-pyrano[4,3-b]benzofuran-1-one structure and their nitrogen analogues which possess powerful antioxidant properties combined with a highly effective UV absorbing functionality in one molecule. These compounds are especially useful in cosmetical and dermatological formulations.

  • Enzyme preparations for use as biocatalysts
    Publication number: 20090017519
    Abstract: The invention is directed to enzyme preparations which are obtainable by enzyme immobilizates which comprise enzymes or microorganisms containing enzymes immobilized on an inert carrier being provided with a silicone coating obtained by hydrosilylation, to a process for producing such enzyme preparations and to the use of enzyme preparations as an industrial biocatalyst.
