The present invention relates to nonlinear oligopyridazine compounds, to processes for obtaining them, to their uses, and also to their reduction to oligopyrroles and to the uses of the pyridazinylpyrrole and oligopyrrole compounds obtained. The invention relates in particular to the uses as medicaments, in particular for treating pathologies such as cancer, bacterial infections or parasitic infections, and also the uses in the materials, environmental, electronics and optics field.
Helicallyfoldedmolecularcapsules based on oligoamide sequences of aromatic amino acids which are capable of binding tartaric acid in organic solvents with high affinity and diastereoselectivity have been synthesized, and their structures and binding properties investigated by (1)H NMR, X-ray crystallography, circular dichroism, and molecular modeling. We found that elongating the helices at their

The present invention relates to linear pyridazine compounds, and more particularly to those of these compounds which are oligopyridazine compounds, to processes for obtaining them, to their uses, and also to their reduction to pyrroles and to the uses of the pyrrole, pyridazinylpyrrole and oligopyrrole compounds obtained. The invention relates in particular to the uses as medicaments, in particular for treating pathologies such as cancer, bacterial infections or parasitic infections, and also the applications in the materials, environmental, electronics and optics field.
A synthetic helical aromatic oligoamide foldamer receptor with highaffinity and selectivity for tartaric acid was subjected to a structure-based evolution of its sequence via mutations, additions, and deletions of monomers to produce a new receptor having highaffinity and selectivity for malic acid, a guest that differs from tartaric acid by a single oxygen atom. Seven iteratively modified sequences

A dinuclearrutheniumcomplex, which acts as a molecular catalyst for wateroxidation, has been synthesized and characterized. The electronic and electrochemical properties were studied by UV−vis spectroscopy and cyclic voltammetry. The oxidation potentials of the complex are significantly lowered by introducing a negatively charged carboxylate ligand, in comparison with those of the reported complexes
