The Effects of Fisetin and Curcumin on Oxidative Damage Caused by Transition Metals in Neurodegenerative Diseases. Mol Neurobiol 2024:10.1007/s12035-024-04321-2. [PMID: 38970766 DOI: 10.1007/s12035-024-04321-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Accepted: 06/19/2024] [Indexed: 07/08/2024]
Abstract
Neurodegenerative diseases pose a significant health challenge for the elderly. The escalating presence of toxic metals and chemicals in the environment is a potential contributor to central nervous system dysfunction and the onset of neurodegenerative conditions. Transition metals play a crucial role in various pathophysiological mechanisms associated with prevalent neurodegenerative diseases such as Alzheimer's and Parkinson's. Given the ubiquitous exposure to metals from diverse sources in everyday life, the workplace, and the environment, most of the population faces regular contact with different forms of these metals. Disturbances in the levels and homeostasis of certain transition metals are closely linked to the manifestation of neurodegenerative disorders. Oxidative damage further exacerbates the progression of neurological consequences. Presently, there exists no curative therapy for individuals afflicted by neurodegenerative diseases, with treatment approaches primarily focusing on alleviating pathological symptoms. Within the realm of biologically active compounds derived from plants, flavonoids and curcuminoids stand out for their extensively documented antioxidant, antiplatelet, and neuroprotective properties. The utilization of these compounds holds the potential to formulate highly effective therapeutic strategies for managing neurodegenerative diseases. This review provides a comprehensive overview of the impact of abnormal metal levels, particularly copper, iron, and zinc, on the initiation and progression of neurodegenerative diseases. Additionally, it aims to elucidate the potential of fisetin and curcumin to inhibit or decelerate the neurodegenerative process.

Abstract
Because of their capacity to bind metals, metal chelators are primarily employed for therapeutic purposes, but they can also find applications as colorimetric reagents and cleaning solutions as well as in soil remediation, electroplating, waste treatment, and so on. For instance, iron-chelation therapy, which is used to treat iron-overload disorders, involves removing excess iron from the blood through the use of particular molecules, like deferoxamine, that have the ability to chelate the metal. The creation of bioinspired and biodegradable chelating agents is a crucial objective that draws inspiration from natural products. In this context, starting from bioavailable molecules such as maltol and pyrogallol, new molecules have been synthetized and characterized by potentiometry, infrared spectroscopy and cyclic voltammetry. Finally, the ability of these to bind iron has been investigated, and the stability constants of ferric complexes are measured using spectrophotometry. These compounds offer intriguing scaffolds for an innovative class of versatile, multipurpose chelating agents.

Abstract
The present work analyzes the complex formation ability towards Pb2+ and Cd2+ of a series of kojic acid derivatives that join the chelating properties of the pyrone molecules and those of polyamines, with the aim of evaluating how the different effects of oxygen and nitrogen coordinating groups act on the stability of metal complexes. Experimental research is carried out using potentiometric and spectrophotometric techniques supported by 1H and 13C NMR spectroscopy and DFT calculations. Actually, a different coordination mechanism toward Pb2+ and Cd2+ was proved: in the case of Pb2+, coordination takes place exclusively via the oxygen atoms, while the contribute of the nitrogen atoms appears relevant in the case of Cd2+. Lead complexes of all the studied ligands are characterized by significantly stronger stability than those of cadmium. Finally, on the basis of the measured complex formation stabilities, some of the proposed molecules seems promising effective ligands for lead and cadmium ion decorporation from polluted soils or waste waters.

Abstract
Access to the enthalpy and entropy of the formation of metal complexes in solution is essential for understanding the factors determining their thermodynamic stability and speciation. As a case study, in this report we systematically examine the complexation of silver(I) in acetonitrile (AN) with the following monoamines: n-propylamine (n-pr), n-butylamine (n-but), hexylamine (hexyl), diethylamine (di-et), dipropylamine (di-pr), dibutylamine (di-but), triethylamine (tri-et) and tripropylamine (tri-pr). The study shows that the complex stabilities are quite independent of the length of the substitution chain on the N atom and demonstrates that, in general, the overall enthalpy terms associated with the complex formation are strongly exothermic, whereas the entropy values oppose the complex formations. In addition, we examined the similarity of the formation constants of AgL complexes of the primary monoamines in AN, dimethylsulfoxide (DMSO) and water, which were unexpected on the basis of the difference between the donor properties of solvents.

Abstract
Metal ions have unique electrochemical and spectroscopical properties that cannot be attained by purely organic compounds. Most of the metal ions are toxic to humans, but paradoxically, metallodrugs are used in medicine as therapeutics and theranostics. Metallodrugs are eliminated in urine and faeces, and therefore release toxic metals and ligands into aquatic ecosystems, thereby raising concerns regarding environmental risks. The use of metallodrugs based on essential metal ions (i.e., iron, copper and zinc), instead of toxic ions, is a new alternative with minor hazards. Kojic acid is an Asperigillus oryzae metabolite of low toxicity used in the food and cosmetics industries. Its derivatives form stable complexes with iron(III) ions, which bind effectively to DNA and inhibit DNA polymerization. The iron(III)/S2 ligand complexes reduce in vitro colon carcinoma (Caco2) cell viability and significantly decrease the cell number. The kojic acid derivative complexes with iron(III) presented here are an alternative to the currently used platinum complexes in cancer therapy.

Abstract
Hydroxypyridinones (HPs) are recognized as excellent chemical tools for engineering a diversity of metal chelating agents, with high affinity for hard metal ions, exhibiting a broad range of activities and applications, namely in medical, biological and environmental contexts. They are easily made and functionalizable towards the tuning of their pharmacokinetic properties or the improving of their metal complex thermodynamic stabilities. In this review, an analysis of the recently published works on hydroxypyridinone-based ligands, that have been mostly addressed for environmental applications, namely for remediation of hard metal ion ecotoxicity in living beings and other biological matrices is carried out. In particular, herein the most recent developments in the design of new chelating systems, from bidentate mono-HP to polydentate multi-HP derivatives, with a structural diversity of soluble or solid-supported backbones are outlined. Along with the ligand design, an analysis of the relationship between their structures and activities is presented and discussed, namely associated with the metal affinity and the thermodynamic stability of the corresponding metal complexes.

Abstract
![]()
Increasing attention
has been recently devoted to 89Zr(IV) and 68Ga(III) radionuclides, due to their favorable
decay characteristics for positron emission tomography (PET). In the
present paper, a deep investigation is presented on Ga(III) and Zr(IV)
complexes with a series of tri-(H3L1, H3L3, H3L4 and desferrioxamine
E, DFOE) and tetrahydroxamate (H4L2) ligands. Herein, we describe the rational
design and synthesis of two cyclic complexing agents (H3L1 and H4L2) bearing three and four hydroxamate
chelating groups, respectively. The ligand structures allow us to
take advantage of the macrocyclic effect; the H4L2 chelator contains an additional side
amino group available for a possible further conjugation with a biomolecule.
The thermodynamic stability of Ga(III) and Zr(IV) complexes in solution
has been measured using a combination of potentiometric and pH-dependent
UV–vis titrations, on the basis of metal–metal competition.
The Zr(IV)-H4L2 complex
is characterized by one of the highest formation constants reported
to date for a tetrahydroxamate zirconium chelate (log β = 45.9,
pZr = 37.0), although the complex-stability increase derived from
the introduction of the fourth hydroxamate binding unit is lower than
that predicted by theoretical calculations. Solution studies on Ga(III)
complexes revealed that H3L1 and H4L2 are stronger chelators in comparison to DFOB. The complex stability
obtained with the new ligands is also compared with that previously
reported for other hydroxamate ligands. In addition to increasing
the library of the thermodynamic stability data of Ga(III) and Zr(IV)
complexes, the present work allows new insights into Ga(III) and Zr(IV)
coordination chemistry and thermodynamics and broadens the selection
of available chelators for 68Ga(III) and 89Zr(IV). Solution equilibria studies on Ga(III)
and Zr(IV) complexes
with a series of tri- and tetrahydroxamate ligands are presented.
For this purpose, the rational design and synthesis of two cyclic
complexing agents bearing three and four hydroxamate chelating groups
was performed. The thermodynamic and speciation studies allow a discussion
of the structure−complex stability dependence. The Zr(IV)-tetrahydroxamate
complex is characterized by one of the highest formation constants
reported to date for a hydroxamate zirconium chelator.

Abstract
A family of combined Kojic acid and polyamine derivatives has been synthesized as phosphate anion and metal ion ligands. The stoichiometry, stability and structure of the ion/ligand adducts were determined by 1H NMR spectroscopy, potentiometry, EXAFS and DFT calculations. The presented dual ligands bind effectively both phosphate anions and metal ions and could be used as effective ion receptors in challenging water conditions in the broad pH range. A careful analysis of the heatmaps of the stability constants allows to choose the most appropriate ligand for the ion for qualitative and/or quantitative analysis in water, without analyte pre-treatment. Extremely high-water solubility (>0.6 M) and ion(s)/ligand stability of the adducts in the pH 3-11 are the greatest advantages of the presented here molecules over other known ion sensors. The presented here molecules represent an innovative class of dual metal/anion ligands, with perspective of medical and environmental use.

Abstract
In an attempt to synthesise new tyrosinase inhibitors, we designed and synthesised a series of chalcone-hydroxypyridinone hybrids as potential tyrosinase inhibitors adopting strategic modifications of kojic acid. All the newly synthesised compounds were characterised by NMR and mass spectrometry. Initial screening of the target compounds demonstrated that compounds 1a, 1d, and 1n had relatively strong inhibitory activities against tyrosinase monophenolase, with IC50 values of 3.07 ± 0.85, 2.25 ± 0.8 and 2.75 ± 1.19 μM, respectively. The inhibitory activity against monophenolase was 6- to 8-fold higher than that of kojic acid. Compounds 1a, 1d, and 1n also showed inhibition of diphenolase, with IC50 values of 17.05 ± 0.07, 11.70 ± 0.03 and 19.3 ± 0.28 μM, respectively. The inhibition kinetics of diphenolase indicates that compounds 1a and 1d induce reversible inhibition on tyrosinase. Finally, we found that copper coordination should be one of the important inhibitory mechanism of these compounds in tyrosinase.

Abstract
![]()
A series of five
rationally designed decapeptides [DEHGTAVMLK (DP1), THMVLAKGED (DP2),
GTAVMLKDEH (Term-DEH), TMVLDEHAKG (Mid-DEH), and DEHGGGGDEH (Bis-DEH)]
have been studied for their interactions with Cu(II) and Mn(II) ions.
The peptides, constructed including the most prevalent amino acid
content found in the cell-free extract of Deinococcus radiodurans (DR), play a fundamental role in the antioxidant mechanism related
to its exceptional radioresistance. Mn(II) ions, in complex with these
peptides, are found to be an essential ingredient for the DR protection
kit. In this work, a detailed characterization of Cu(II) systems was
included, because Cu(II)–peptide complexes have also shown
remarkable antioxidant properties. All peptides studied contain in
their sequence coordinating residues that can bind effectively Mn(II)
or Cu(II) ions with high affinity, such as Asp, Glu, and His. Using
potentiometric techniques, NMR, EPR, UV–vis, and CD spectroscopies,
ESI-MS spectrometry, and molecular model calculations, we explored
the binding properties and coordination modes of all peptides toward
the two metal ions, were able to make a metal affinity comparison
for each metal system, and built a structural molecular model for
the most stable Cu(II) and Mn(II) complexes in agreement with experimental
evidence. Five rationally designed decapeptides
reconstituted from the cell-free extract of Deinococcus radiodurans have been precisely analyzed in terms of their coordination properties
toward Mn(II) and Cu(II). The results provide new insight to enhance
our understanding of the impact of metal complexes in the protection
of the bacterium from various damaging agents such as ionizing radiation,
ultraviolet radiation, and oxidative stress and novel information
useful for exploiting this extraordinary ability in future biotechnological
applications.

Abstract
Kojic acid is an important biomolecule, currently produced by fermentation and having a wide range of potential applications. A faster and more direct chemical route could open the door for its large-scale production and wider utilization in biorefineries. Here we describe an efficient method for the preparation of kojic acid from d-glucose via glucosone by a three-step chemo-enzymatic route.

Abstract
Hydroxypyrone derivatives have a good bioavailability in rats and mice and have been used in drug development. Moreover, they show chelating properties towards vanadyl cation that could be used in insulin-mimetic compound development. In this work, the formation of coordination compounds of oxovanadium(IV) with four kojic acid (5-hydroxy-2-(hydroxymethyl)-4-pyrone) derivatives was studied. The synthetized studied ligands (S2, S3, S4, and SC) have two or three kojic acid units linked through diamines or tris(2-aminoethyl)amine chains, respectively. The chemical systems were studied by potentiometry (25 °C, ionic strength 0.1 mol L-1 with KCl), and UV-visible and EPR spectroscopy. The experimental data were analyzed by a thermodynamic and a chemometric (Multivariate Curve Resolution-Alternating Least Squares) approach. Chemical coordination models were proposed, together with the species formation constants and the pure estimated UV-vis and EPR spectra. In all systems, the coordination of the oxovanadium(IV) starts already under acidic conditions (the cation is totally bound at pH higher than 3-4) and the metal species remain stable even at pH 8. Ligands S3, S4, and SC form three coordination species. Two of them are probably due to the successive insertion of the kojate units in the coordination shell, whereas the third is most likely a hydrolytic species.
