4-[(2-Amino-4-phenylazo)-methyl]-cyclo hexane carboxylic acid, a new Azo (LH2) ligand, was synthesized by reaction of the diazonium salt trans-4-(amino-methyl) cyclo acid with 3-amino phenol. The azo ligand characterized micro elemental analysis (C.H.N.O.) and TGA as well spectroscopic techniques (UV-Vis, FTIR, 1H-NMR, LC-Mass). Atomic absorption, analysis, infrared, LC-Mass, TGA, UV-Vis spectr...

Eine Reihe gespannter aromatischer Makrozyklen basierend auf [n]Cyclo-2,7-(4,5,9,10-tetrahydro)pyrenylenen wurde an der K-Region Pyreneinheit mit Ethylenglykol-Gruppen funktionalisiert, um im Innenraum des Makrozyklus eine definierte Bindungstasche zu formen. Diese ist für den fünfgliedrigen besonders ausgeprägt, was einer Bindungskonstante von 8.0×104 m−1 zwischen dem Ether-dekorierten [5]Cycl...

THE TITLE COMPOUND [SYSTEMATIC NAME: 14,15-dihy-droxy-7,7-dimethyl-13-(propan-2-yl)tricyclo-[9.4.0.0(3,8)]penta-deca-1(11),3(8),9,12,14-pentaen-4-one], C(20)H(24)O(3), is a new icetexane diterpenoid which was isolated from the roots of Premna obtusifolia (Verbenaceae). The mol-ecule has three fused rings: a cyclo-hexenone, a central cyclo-heptene and a benzene ring. The cyclo-hexenone ring is i...

We developed a bioadhesive coating based on a synthetic peptide-conjugate (AK-cyclo[RGDfC]) which contains multiples of the arginyl-glycyl-aspartic acid (RGD) amino acid sequence. Biotinylated AK-cyclo[RGDfC] is bound to a supported lipid bilayer via a streptavidin interlayer. Layering, hydration and packing of the coating is quantified by X-ray and neutron reflectometry experiments. AK-cyclo[R...
