Mast cells are protective against snake venom sarafotoxins that belong to the endothelin (ET) peptide family. The molecular mechanism underlying this recently recognized innate defense pathway is unknown, but secretory granule proteases have been invoked. To specifically disrupt a single protease function without affecting expression of other proteases, we(More)
Transmembrane signaling of the CXC chemokine stromal cell-derived factor-1 (SDF-1) is mediated by CXCR4, a G protein-coupled receptor initially identified in leukocytes and shown to serve as a coreceptor for the entry of HIV into lymphocytes. Characterization of SDF-1- and CXCR4-deficient mice has revealed that SDF-1 and CXCR4 are of vital developmental(More)
We have synthesized and characterized a series of dendritic oligothiophenes comprising peripheral mannose functionalities by copper-mediated 1,3-dipolar cycloaddition reaction. The hybrids were accessible either by attachment of acetyl-protected mannosides at the dendritic oligothiophene or by the direct synthesis of the deprotected mannose-oligothiophene(More)
Metal ion-binding of synthetic peptides containing HxH and CxxC motifs was investigated by electrospray ionization mass spectrometry (ESI-MS) and metal chelate affinity chromatography. A high affinity of Ni2+ and Cu2+ to HxH containing sequences was found. Based on their natural metal ion-binding potential it was possible to include metal affinity(More)
A new method for the isolation of proteins separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), using electroelution with a modified buffer system, is described. The method is suitable for direct characterization by electrospray-ionization mass spectrometry (ESI-MS), or alternatively matrix-assisted laser desorption-ionization(More)
The synthesis of generational dendritic oligothiophenes (DOTs) has been successfully achieved by a divergent/convergent approach that involves halogenation, boronation, and palladium-catalyzed Suzuki coupling reactions. The key point in the presented synthetic approach is the use of trimethylsilyl (TMS) protecting groups, which allow for the core-lithiation(More)
Novel photocatalysts based on ruthenium complexes with NHC (N-heterocyclic carbene)-type bridging ligands have been prepared and structurally and photophysically characterised. The identity of the NHC-unit of the bridging ligand was established unambiguously by means of X-ray structural analysis of a heterodinuclear ruthenium-silver complex. The(More)
, a series of rhenium(i) tricarbonyl chloride complexes with bpy-R2 derivatives (bpy = 2,2'-bipyridine, R represents the substitution at the 4- and 4'-positions), and their corresponding trishomoleptic as well as heteroleptic ruthenium(ii) complexes and have been synthesized and characterized. Their applicability as immobilizable metal-organic chromophores(More)
