Quaterpyridines have been demonstrated to be useful building blocks in metallo-supramolecular chemistry; however, their synthesis requires the preparation of sensitive building blocks. We present here three examples of nonsymmetric quaterpyridines that were easily obtained in yields of 70-85% by condensation of commercially available enones with… (More)
The 4'-(2-fluorenyl)-2,2':6',2''-terpyridine (FT) ligand and its cis(Cl,Cl)- and trans(Cl,Cl)-[Ru(II)(FT)Cl2(NO)](PF6) complexes have been synthesized. Both isomers were separated by HPLC and fully characterized by (1)H and (13)C NMR. The X-ray diffraction crystal structures were solved for FT (Pna21 space group, a = 34.960(4), b = 5.9306(7), c = 9.5911(10)… (More)
Combined coordination of Zn(II) and Cu(I) or Cu(II) to the amyloid-β peptide has been investigated using XANES, EPR and NMR spectroscopies. While Zn(II) does alter Cu(II) binding to Aβ, this has no effect on (Aβ)Cu induced ROS production and associated cell toxicity.
