The selectins and their ligands

Current Opinion in Cell Biology, 1994
The selectins are a family of carbohydrate-binding proteins, or lectins, that have stimulated tremendous interest because of their involvement in a wide array of interactions between leukocytes and endothelial cells. Highlights of recent progress include an extension of the list of instances of selectin participation in inflammatory diseases, further ...

Smart N-Heterocyclic Carbene Ligands in Catalysis.

Chemical Reviews, 2017
It is well-recognized that N-heterocyclic carbene (NHC) ligands have provided a new dimension to the design of homogeneous catalysts. Part of the success of this type of ligands resides in the limitless access to a variety of topologies with tuned ...

Intramolecular ligand-ligand interactions in mixed ligand complexes

Journal of Molecular Catalysis, 1984
Abstract Intramolecular ligand-ligand interactions in the ternary Cu(II)- and Pd(II)- amino acid systems have been investigated by synthetic, spectroscopic and potentiometric methods. Various ternary Cu(II)- and Pd(II)- complexes containing amino acids with charged and/or polar side groups were isolated as crystals. Electrostatic interactions between

Influence of Ligands

2020
The adsorption of small molecules on the metal center of 3d metal phthalocyanines alters the bonding scheme of the molecule and can induce different spin states and magnetic moments, as well as trigger more exotic effects like Kondo resonance. Soft X-ray spectroscopy studies and computational studies have highlighted this kind of effects in magnetic ...

The inductive effect and ligand–ligand interactions in mutual influence of ligands

Inorganica Chimica Acta, 1978
Abstract The inductive effect in series AF(n + 1)−5 and AF5Cln− (A = Si, P, S, Se) has been calculated by an approximate non-empiric method. The effect is directed primarily along the cis-coordinate; with isoelectronic compounds of one period elements it is growing along the period from the left to the right. The role of ligand–ligand interactions in

Ligand-to-ligand charge-transfer photochemistry

Journal of the American Chemical Society, 1993
The photochemistry and photophysics are reported for a unique series of complexes of the type fac-(bpy)-Re I (CO) 3 -(α-AA), where bpy=2,2'-bipyridine and α-AA is a «reactive donor ligand» that incorporates an α-amino alcohol functionality. Photoexcitation of these complexes into the dπ(Re)→π * (bpy) metal-to-ligand charge-transfer manifold is followed

Bile acids: natural ligands for an orphan nuclear receptor.

Science, 1999
Bile acids regulate the transcription of genes that control cholesterol homeostasis through molecular mechanisms that are poorly understood. Physiological concentrations of free and conjugated chenodeoxycholic acid, lithocholic acid, and deoxycholic acid

Structural variation in copper(I) complexes with pyridylmethylamide ligands: structural analysis with a new four-coordinate geometry index, tau4.

Dalton Transactions, 2007
Four Cu(I) complexes were synthesized with a family of pyridylmethylamide ligands, HL(R) [HL(R) = N-(2-pyridylmethyl)acetamide, R = null; 2,2-dimethyl-N-(2-pyridylmethyl)propionamide, R = Me(3); 2,2,2-triphenyl-N-(2-pyridylmethyl)acetamide, R = Ph(3 ...
