Molecular structures of dinuclear zinc(II) complexes of chiral tridentate imine and amine ligands : effect of ligand geometry on diastereoselectivity Universiteit Gent
Homogeneous Metal Catalysts with Inorganic Ligands: Probing Ligand Effects in Lewis Acid Catalyzed Direct Amide Bond Formation KU Leuven
Inorganic clusters have large potential in the development of effective and robust catalysts due to their tunable electronic and structural properties and the ability to bind and stabilize catalytic metals. However, they have been rarely used as ligands in homogeneous metal catalysis, and the effect of the ligand structure on the catalyst’s reactivity has been scarcely investigated. By using well-defined and soluble inorganic clusters such as ...
CC chemokine ligand-2 synergizes with the nonchemokine G protein-coupled receptor ligand fMLP in monocyte chemotaxis, and it cooperates with the TLR ligand LPS via induction of CXCL8 KU Leuven
During inflammatory reactions, endogenously produced cytokines and chemokines act in a network and interact with hormones and neurotransmitters to regulate host immune responses. These signaling circuitries are even more interfaced during infections, when microbial agonists activate TLR, RLR, and NLR receptors. On the basis of the discovery of synergy between chemokines for neutrophil attraction, we extend here this phenomenon between the ...
Insights into the Structural Determinants Required for High-Affinity Binding of Chiral Cyclopropane-Containing Ligands to α4β2-Nicotinic Acetylcholine Receptors: An Integrated Approach to Behaviorally Active Nicotinic Ligands KU Leuven
Structure-based drug design can potentially accelerate the development of new therapeutics. In this study, a cocrystal structure of the acetylcholine binding protein (AChBP) from Capitella teleta (Ct) in complex with a cyclopropane-containing selective α4β2-nicotinic acetylcholine receptor (nAChR) partial agonist (compound 5) was acquired. The structural determinants required for ligand binding obtained from this AChBP X-ray structure were used ...
Synthesis and application of chiral dienes and chiral imidates as ligands for transition metal catalysis Universiteit Gent
In this dissertation, two main ligandclasses have been studied: chiral diene ligands and chiral imidate ligands. We developed a novel route to synthesize chiral disubstituted bicyclo[2.2.1]heptadienes (R= i-Bu, c-Hex, Benzyl and allyl) starting from enantiomerically pure bistriflate. The synthesized diene ligands were tested in the rhodium(I)-catalyzed 1,4-addition of phenylboronic acids to cyclic enones (up to 96% ee) and α-acetamido acrylic ...
Influence of bulky yet flexible N-heterocyclic carbene ligands in gold catalysis Universiteit Gent
Three new Au(I) complexes of the formula [Au(NHC)(NTf2)] (NHC = N-heterocyclic carbene) bearing bulky and flexible ligands have been synthesised. The ligands studied are IPent, IHept and INon which belong to the 'ITent' ('Tent' for 'tentacular') family of NHC derivatives. The effect of these ligands in gold-promoted transformations has been investigated.
