AI Article Synopsis

  • The study involves the characterization of three ternary metal complexes featuring copper and cobalt, which were synthesized with specific ligands including adipic acid and 1,10-phenanthroline.
  • Spectroscopic techniques like FTIR and X-ray crystallography were used to analyze the bonding and geometry of these complexes, revealing octahedral and square pyramidal shapes for different compounds.
  • The complexes exhibit varying superoxide dismutase (SOD) mimic activities, with the order of effectiveness being copper complex 1, followed by 3, and then cobalt complex 2.

Article Abstract

The present ternary complexes [Cu(ada)(phen)(H(2)O)]·2H(2)O (1), [Co(2)(ada)(2)(phen)(2)(H(2)O)(2)] (2) and [{Cu(ada)(3)(bipy)}(n)·3nH(2)O] (3) (H(2)ada=adipic acid, phen=1,10-phenanthroline and bipy=2,2'-bipyridine) obtained under varying experimental conditions were characterized by spectral, electrochemical and thermal studies. The bonding modes and the spatial arrangements of the carboxylate dianion around the metal ions have been investigated employing FTIR, EPR and X-ray crystallographic studies. Present data revealed a six coordinate distorted octahedral geometry for 2 with a=8.068, b=9.788, c=11.788Å, α=70.464, β=75.109, γ=72.063° and a five coordinate square pyramidal geometry for 3 with a=9.509, b=9.912, c=12.656Å, α=70.486, β=73.604, γ=75.162°. The superoxide dismutase (SOD) mimic activities of the complexes are in the order 1>3>2.

ConspectusThe redox reactivity of transition metal centers can be augmented by nearby redox-active inorganic or organic moieties. In some cases, these functional groups can even allow a metal center to participate in reactions that were previously inaccessible to both the metal center and the functional group by themselves. Our research groups have been synthesizing and characterizing coordination complexes with polydentate quinol-containing ligands.

Superoxide dismutase enzymes are a major defense against superoxide, which is a potent reactive oxygen species. Misregulation of reactive oxygen species and subsequent neuronal damage are etiological hallmarks of neurodegenerative disease. Macrocyclic small molecules have offered inroads toward functional SOD1 mimics.

Free radicals such as superoxide are reactive species that, upon accumulation, lead to oxidative stress. The superoxide dismutase (SOD) enzyme mitigates this stress by converting superoxide into hydrogen peroxide and oxygen. However, the probable lack of SOD supplementation has driven the search for alternatives, with copper complexes emerging as promising candidates.

The disorder and heterogeneity of low-molecular-weight amyloid-beta oligomers (AβOs) underlie their participation in multiple modes of cellular dysfunction associated with the etiology of Alzheimer's disease (AD). The lack of specified conformational states in these species complicates efforts to select or design small molecules to targeting discrete pathogenic states. Furthermore, targeting AβOs alone may be therapeutically insufficient, as AD progresses as a multifactorial, self-amplifying cascade.
