  • Paleek, Jiri; Zweigerdt, Robert; Olmer, Ruth; Martin, Ulrich; Kirschning, Andreas; Dräger, Gerald (Cambridge : Royal Society of Chemistry, 2011)
    A practical synthesis of the Rho-Kinase inhibitor Y-27632 and two new fluoro derivatives was achieved in seven steps and with a good overall yield of 45% starting from commercially available (R)-1-phenylethylamine. Compared ...
  • Taskova, Rilka M.; Mitova, Maya; Mikhova, Bozhanka; Duddeck, Helmut (Berlin : De Gruyter, 2003)
    Two flavonoid aglycons, eight flavonoid glycosides, chlorogenic acid and syringin were isolated from aerial parts of Carthamus lanatus. Isorhamnetin 3-O-β-D-glucoside and chlorogenic acid were found for the first time in ...
  • Schöttner, M.; Ganßer, D.; Spiteller, G. (Berlin : De Gruyter, 1997)
    Lignans bind to sex hormone-binding globulin (SHBG). The lignan with the highest binding affinity is (±)-3,4-divanillyltetrahydrofuran. In a double Stobbe condensation - without use of protecting groups - a wide variety ...
  • Mattiza, Jens T.; Fohrer, Joerg G.G.; Duddeck, Helmut; Gardiner, Michael G.; Ghanem, Ashraf (Cambridge : Royal Society of Chemistry, 2011)
    Thirteen enantiopure paddlewheel-shaped dirhodium(II) tetrakiscarboxylate complexes have been checked for their efficiency in the dirhodium method (differentiation of enantiomers by NMR spectroscopy); six of them are new. ...
  • Mikhova, Bozhanka; Duddeck, Helmut; Taskova, Rilka M.; Mitova, Maya; Alipieva, Kalina (Berlin : De Gruyter, 2004)
    The aerial parts of Carthamus lanatus (Asteraceae) afforded four new oxygenated bisabolane fucosides, 10-hydroperoxy-bisabola-2,11-diene 7-O-β-D-fucopyranoside, 11-hydroperoxy-bisabola-2,9-diene 7-O-β-D-fucopyranoside, ...
  • Franke, Jana; Eichner, Simone; Zeilinger, Carsten; Kirschning, Andreas (Cambridge : Royal Society of Chemistry, 2013)
    Covering: 2005 to 2013 In this review recent progress in the development of heat shock proteins (Hsp90) in oncogenesis is illuminated. Particular emphasis is put on inhibitors such as geldanamycin and analogues that serve ...
  • Wegner, Jens; Ceylan, Sascha; Kirschning, Andreas (Cambridge : Royal Society of Chemistry, 2011)
    Ten essentials of synthesis in the flow mode, a new enabling technology in organic chemistry, are highlighted as flashlighted providing an insight into current and future issues and developments in this field. © The Royal ...
  • Barbier, Jenny; Gerth, Klaus; Jansen, Rolf; Kirschning, Andreas (Cambridge : Royal Society of Chemistry, 2012)
    The total synthesis of noricumazole B, a secondary metabolite from myxobacteria, was achieved. It established the glycan moiety to be D-α-arabinoside. © The Royal Society of Chemistry 2012.
  • Oum, Kawon; Lohse, Peter W.; Flender, Oliver; Klein, Johannes R.; Scholz, Mirko; Lenzer, Thomas; Du, Juan; Oekermann, Torsten (Cambridge : Royal Society of Chemistry, 2012)
    The ultrafast photoinjection and subsequent relaxation steps of the indoline dye D149 were investigated in detail for a mesoporous electrodeposited ZnO thin film and compared with experiments on sintered TiO2 and ZrO2 thin ...
