Mechanistic Investigation of a HAuCl4 catalyzed oxidative C-C coupling reaction and Synthesis of new supramolecular Silver(I) and Gold(I) NHC compounds: or handling of a Mass Spectrometric Challenge and catching Counterions on Supramolecular Playgrounds
(2021-04-22)
Reaction monitoring by electrospray (ESI) mass spectrometry is a valuable technique to investigate reaction mechanisms. It allows a glimpse into the reacting solution and the characterization of transient intermediates ......
Application of BioID to in vitro organelle and in vivo cell-type-specific proteomics
(2020-09-17)
A genetically modified biotin ligase BirA (Arg118Gly), termed BioID (BirA*), can be induced to add a reactive form of biotin to proximate proteins in the cytosol and nucleus. The biotinylated proteins can be purified and ......
Funktionelle Untersuchungen des ABC-Transporters ABCG2
(2021-10-15)
Das Phänomen der Multidrug Resistance (MDR) stellt ein bedeutsames Problem bei der Behandlung von Tumoren mit Chemotherapeutika dar. Die ABC-Transporter ABCB1, ABCC1 und ABCG2 sind an der Entstehung der MDR beteiligt. ...
In situ observations of reaction and transport phenomena during silicate glass corrosion by fluid-cell Raman spectroscopy: Method development and applications
(2020-07-06)
Borosilicate glass is the preferred material for the immobilization of high-level nuclear waste and an important material for various industries. Silicate glasses, however, are prone to corrosion by aqueous solutions, which ......
Characterization and application of fusogenic liposomes
(2020-02-03)
Conventional drug delivery strategies use the endocytic pathway to introduce biomolecules like proteins, DNA, or antibiotics into living cells. The main disadvantage of endocytic uptake is the quick intercellular degradation ......
Beiträge zur Totalsynthese von Lysolipin I
(2020-06-12)
Die vorliegende Dissertation behandelt Studien zur Totalsynthese des Sekundärmetabolits Lysolipin I (1), eines der höchst-oxidierten, aromatischen Polyketide. Der heptazyklische Kern dieses potenten Antibiotiukums beinhaltet ...
Studien zur Total- und Biosynthese von PR Toxin
(2020-03-06)
Diese Arbeit beschäftigt sich mit dem Pilzgift PR Toxin, welches aus Penicillium roqueforti isoliert werden kann. Es wurden einerseits drei Ansätze für eine Totalsynthese entwickelt und andererseits grundlegende Arbeiten ...
Regenerated Hoof Keratin from 1-Ethyl-3-Methylimidazolium Acetate and Insights into Disulfide-Ionic Liquid Interactions from MD Simulation
(2020-06-08)
Regeneration of the hoof keratin from ionic liquids was never successful in the past because the ionic liquids were not strong enough. However, this biomaterial starts to play a central role for the preparation of biofilms ...
Acid-Catalyzed Rearrangements of 3-Aryloxirane-2-Carboxamides: Novel DFT Mechanistic Insights
(2020-07-01)
Efficient synthesis of 3-arylquinolin-2(1H)-ones and N-(2-carboxyaryl)-oxalamides from protic acid-catalyzed rearrangements of 3-aryloxirane-2-carboxamides was achieved recently but not well understood. In contrast to the ...
Activity coefficients of binary methanol alcohol mixtures from cluster weighting
(2020-07-23)
The hydrogen bond network of different small alcohols is investigated via cluster analysis. Methanol/alcohol mixtures are studied with increasing chain length and branching of the molecule. Those changes can play an important ...
