Abstract:
Adipositas und das damit häufig vergesellschaftete metabolische Syndrom sind Volkskrankheiten mit immenser medizinischer und ökonomischer Bedeutung. Aus Fett- und Muskelzellen freigesetzte Proteohormone, sogenannte Adipomyokine, spielen eine wichtige Rolle in der Pathogenese der Adipositas und ihrer Folgeerkrankungen. Irisin wurde vor kurzem als ein neues Adipomyokin beschrieben, welches die Umwandlung von weißen in beige Adipozyten stimuliert und darüber die Thermogenese induziert. Der durch erhöhte Irisinspiegel steigende Energieumsatz führte in experimentellen Mausstudien zu einer Gewichtsa

Abstract:
The oxidative addition of the N-H bond of both heterocyclic and acyclic amines and the O-H bond of phenols, water and carboxylic acids to iridium(I) trimethylphosphines complexes was studied and the reactivity of the resulting hydrido amido-, aryloxo- and carboxylato iridium(III) complexes was investigated. Oxidative addition of the N-H bond of pyrrole, indole, 3-methylindole, 7-azaindole, carbazole and aniline to [Ir(COD)(PMe₃)₃]CI (<b>1a</b>) (COD = 1,5-cyclooctadiene) produces merIr( NR₂)H(PMe₃)₃CI (<b>2a-f</b>) complexes.
