  • Patent number: 8642761
    Abstract: The present invention describes a method for the synthesis of enantiomerically pure 3-amidinophenylalanine derivatives, which are used as pharmaceutically effective urokinase inhibitors, by starting from 3-cyanophenylalanine derivatives. The methods of manufacture comprising only one synthesis step lead to new intermediates, namely 3-hydroxyamidino- and 3-amidrazonophenylalanine derivatives. These intermediates or their acetyl derivatives can be reduced into the desired 3-amidino-phenylalanine derivatives under gentle conditions (H2 or ammonium formiate, Pd/C (approx. 10%), ethanol/water, room temperature, normal pressure or also H2, Pd/C, AcOH or HCl/ethanol, 1-3 bar) in excellent yields and in an enantiomeric excess of up to 99.9%.

  • Publication number: 20120177710
    Abstract: Topical composition for use especially as a skin lightener, characterized in that it contains an effective amount of at least one compound of general formula (I) or a mixture of such compounds and/or an acid addition salt thereof: in which X is NH or a direct bond and n is 2, 3 or 4, preferably 2 or 3, and its use for lightening skin colour, for depigmenting liver spots and for evening out non-uniformities in skin colouration. The invention further relates to dermatologically effective compositions containing at least one disulfide of general formula (I) and at least one additional skin care ingredient.
