Free radicals and antioxidants in normal physiological functions and human disease.
Reactive oxygen species (ROS) and reactive nitrogen species (RNS, e.g. nitric oxide, NO(*)) are well recognised for playing a dual role as both deleterious and beneficial species. ROS and RNS areExpand
Free radicals, metals and antioxidants in oxidative stress-induced cancer.
Oxygen-free radicals, more generally known as reactive oxygen species (ROS) along with reactive nitrogen species (RNS) are well recognised for playing a dual role as both deleterious and beneficialExpand
Hydrogen-bonded coordination network in crystal structures of [Cu(3-PM)4Cl2] and [Cu(4-PM)4Cl]Cl, (PM = pyridylmethanol)
The crystal and molecular structures of [Cu(3-PM)4Cl2] (1) and [Cu(4-PM)4Cl]Cl (2) have been determinated by X-ray crystallography. Complex 1 crystallizes in the triclinic system, space group P−1,Expand
Crystal structures and spectroscopic behavior of monomeric, dimeric and polymeric copper(II) chloroacetate adducts with isonicotinamide, N-methylnicotinamide and N,N-diethylnicotinamide
Abstract Substituted pyridines provide structural rigidity and thus permit the metal coordination geometry to guide the direction of propagation of the hydrogen-bonded links between building blocks.Expand
New Synthetic Approach to C5-Hydroxymethyl-Substituted Polyhydroxylated Pyrrolizidines
A new approach to C5-hydroxymethyl-substituted pyrrolizidines involving 1,3-dipolar cycloaddition of a d -mannose-derived cyclic nitrone and the SN-reaction of a silyl ketene acetal is presented. TheExpand
Anion driven modulation of magnetic intermolecular interactions and spin crossover properties in an isomorphous series of mononuclear iron(III) complexes with a hexadentate Schiff base ligand
A series of spin crossover iron(III) complexes with the general composition [Fe(4OH-L6)]X (H2-4OH-L6 = 1,8-bis(4-hydroxysalicylaldiminato)-3,6-diazaoctane; X = Cl, 1a; Br, 1b; I, 1c) was prepared. AExpand
Structure and magnetism of mono-, di-, and trinuclear benzoato cobalt(II) complexes
Abstract Three cobalt(II) – benzoato (bz) complexes have been prepared and structurally characterized. In the mononuclear complex trans-[Co(bz)2(H2O)2(nca)2] the benzoato ligand is unidentate (nca =Expand
Magnetism of dinuclear benzoato cobalt(II) complexes modeled by a general bilinear exchange
Abstract Combination of the cobalt(II) benzoate with N-heterocyclic ligands L-pyridine, 4-methylpyridine, iso-quinoline, furo[3,2-c]pyridine, 2-methylfuro[3,2-c]pyridine andExpand
Structure and spectral study of copper(II) pyridinecarboxylates: crystal and molecular structure of trans-diaqua-bis(N,N-diethylnicotinamide-N)bis(2-chloronicotinate-O)copper(II)
Abstract New copper(II) pyridinecarboxylate compounds of the composition [CuX2(Et2nia)2(H2O)2] (where X=2-methylthionicotinate (2-MeSnic), 2-chloronicotinate (2-Clnic), 2,6-dichloronicotinateExpand
Synthesis, spectral and magnetic properties of two different 2-nitrobenzoatocopper(II) complexes containing N,N-diethylnicotinamide
Abstract Two structurally different complexes, [Cu2(2-NO2Bz)4(denia)1]n (1) and [Cu(2-NO2Bz)2(denia)2(H2O)2] (2), were prepared from the same reaction (where 2-NO2Bz = 2-nitrobenzoate, denia =Expand
