Sialic acids (Sia) are derivatives of the nine-carbon neuraminic acid monosaccharide (Fig. 1). To date, about 40 of these neuraminic acid modifications have been found to occur in nature (Table 1). Their structure, occurrence and metabolic pathways have been reviewed in detail (Rosenberg 1995; Kelm and Schauer 1997; Schauer and Kamerling 1997; Varki ...

Integrins are expressed on almost every cell type and are responsible for the linkage of the extracellular matrix with the cytoskeleton. In this review I have focused on the intra- and extracellular proteins that bind to integrins. Although many integrins bind to the same extracellular ligand, they mostly recognize different sites on these ligands ...

Complexes of Polypyrazolylborate ligands
Journal of Organometallic Chemistry, 1972Abstract Studies of the structures of [HB(pz)3](C5H5)(CO)2Mo and [Et2B(pz)2]-(C5H5)(CO)2Mo, where HB(pz)3 and Et2B(pz)2 represent the hydridotris(pyrazolyl)-borate and the diethylbis(pyrazolyl)borate groups respectively, have been carried out on solutions using infrared and PMR spectra.

The 'model-free' screening engine ProPose implements a general method for performing simultaneous protein-ligand docking, ligand-ligand alignment, pharmacophore queries-and combinations thereof-in order to incorporate a priori information into screening protocols.

Ligand-to-ligand charge-transfer photochemistry
Journal of the American Chemical Society, 1993The 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
