Antisense oligodeoxynucleotides (ODNs) can inhibit gene expression in a specific manner. However, several studies described problems with cerebral ODN application. Here, we investigated the immune effects (interleukin-6 (IL-6) release, cell invasion

The C(2)-symmetric chiral pinene[5,6]bipyridine V (Chart 1) was synthesized according to a procedure published by our group recently (Kolp, B.; Abeln, D.; Stoeckli-Evans, H.; Zelewsky, A. v. Eur. J. Inorg. Chem. 2001, 1207). A series of stereoselecti

Substituted mono- and bis-pinene-[5,6]-bipyridines are useful ligands in asymmetric copper-catalyzed cyclopropanation by styrenes. Copper complexes were prepared either in situ or prior to the reaction. The catalytic reaction of styrene with ethyl di

The synthesis of a number of bis-thiohydroxamic acids with linking groups of varying lengths and rigidities are reported as potential Pb2+-specific chelating agents. In contrast to the predictions of CaChe® and CAVAET© molecular mechanics programs,

Nordesferriferrithiocin, NDFFTH(2), is a derivative of the siderophore desferriferrithiocin, DFFTH(2), in which the methyl group is substituted by a hydrogen atom. Both compounds show high oral activity as possible drugs for the treatment of iron ove

An improved synthesis of thiohydroxamic acids is described. The reaction of carboxymethyl dithiophenylacetate with several substituted hydroxylamines in aqueous solution at neutral pH gives good yields of the resultant thiohydroxamic acids. The lead

The reaction of lithiated catechol ligands with W (0)Cl4 produces LiCl as a side product. The lithium chloride from this reaction crystallizes as (THF)2Li(μ-Cl)-,Li(THF)2. The X -ray analysis shows lithium in the center of a distorted tetrahedron ma
