  • Disaccharides for drug discovery
    Publication number: 20110201794
    Abstract: Methods are described for the preparation of combinatorial libraries of potentially biologically active disaccharide compounds. These compounds are variously functionalized, with a view to varying lipid solubility size, function an other properties, with the particular aim of discovering novel drug or drug-like compounds, or compounds with useful properties. The invention provides intermediates, processes and synthetic strategies for the solution or solid phase synthesis of disaccharides, variously functionalized about the sugar ring, including the addition of aromaticity and charge, and the placement of pharmaceutically useful groups and isosteres.
    Type: Application
    Filed: December 17, 2010
    Publication date: August 18, 2011
    Applicant: Alchemia Limited
    Inventors: Wim Meutermans, Michael L. West, George Adamson, Giang Thanh Le, Nicholas B. Drinnan, Giovani Abbenante, Bernd Becker, Matthias Grathwohl, Premraj Rajaratnam, Gerald Tometzki
