Fig. 1. Chemical structures of ligands used to characterize, clone, and purify the GABAb receptor. The recently identified positive allosteric modulators CGP7930 and CGP 13501 are expected to broaden the spectrum of therapeutic applications for GABAb drugs.

The use of structure-based virtual screening toward novel nuclear hormone receptor antagonists was described by Schapira et al. [263]. As only X-ray structures of ligand binding domains of agonist-bound nuclear receptors with exception of the antagonist-bound estrogen receptor-a are available, the authors constructed an inactive ... 

In aqueous solution, cA-[Ru (0)(pyen)Cl] has also been generated electrochemically from cA-[Ru (pyen)Cl(OH2)] (see Figure 3 for structure of ligand). This Ru 0x0 complex has an ii°(Ru ) value of 1.29 V vs. SCE and it is an active catalyst for the electrochemical oxidation of alcohols and THF. The rate constants for the oxidation of PhCH20H, CH3OH, CH3OD, and... 

A ruthenium(IV) 0x0 complex containing pyridyl-type ligands, [Ru (0)(N40)l (see Figure 14 for structures of ligand), has been generated by electrochemical oxidation of [Ru (N40)(0H2)] in aqueous solution (pH > 3.5). This species was found to disproportionate to Ru" and Ru in acidic solution." ... 

There are very few osmium(IV) 0x0 species. There is evidence that the Os =0 species is more reactive than the corresponding Os (0)2 species. [Os (0)2(phenba)] (see Figure 12 for structure of ligand) is able to oxidize benzyl alcohol in the presence of one equivalent of PPhs, the active... 

Crystal structure determinations have been reported for compounds 8 99),15 100),19 101), 21 102). Figures 5a and 6a show the structures of ligands 15 and 19. The crystal structure of the macrobicyclic ligand30,...
