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.

Toxicon 2024; 237:107351. [PMID: 37984681 DOI: 10.1016/j.toxicon.2023.107351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 11/07/2023] [Accepted: 11/14/2023] [Indexed: 11/22/2023]
Abstract
This study proposes an alternative method using Na2EDTA to neutralize B. alternatus venom and using it as an immunogen from the start of inoculation to minimize side effects and enhance antivenom production. To achieve this, 1.8 mg/mL of B. alternatus venom (B.aV) was treated with Na2EDTA, and any extra chelate was eliminated by filtering the resulting solution through a Sephadex G-25 column. Two groups of BALB/c mice were immunized subcutaneously on days 1, 15 and 30 with B.aV/Na2EDTA (45, 90, 135 μg/mouse) or B.aV (15, 30, 45 μg/mouse), respectively. Both formulations were emulsified with Freund's adjuvant (complete first and incomplete-booster). Blood samples were collected from each mouse on days 14, 29, 41, and 50 post-first immunization, and serum was separated for antibody detection. Animals were then sacrificed and lungs removed for histological analysis (hematoxylin-eosin). Immunoblotting analysis revealed that the sera from mice inoculated with B.aV/Na2EDTA (anti-B.aV/Na2EDTA) recognized the major venom proteins (20-66 kDa) similarly to the sera from mice inoculated with B.aV (anti-B.aV). The enzyme-linked immunosorbent assay results indicated that the anti-B.aV/Na2EDTA had a higher titer (5.76 × 104) than those the anti-B.aV (1.92 × 104). Additionally, sera from animals immunized with B.aV/Na2EDTA significantly neutralized proteolytic, indirect hemolytic and coagulant activity (p < 0.05). Finally, histological examination of the lungs of mice inoculated with B.aV/Na2EDTA showed normal appearance, while animals inoculated with B.aV showed interstitial lung injury (p < 0.05). In conclusion, the B.aV/Na2EDTA formulation, free of excess Na2EDTA, proved to be a promising candidate as an immunogen for antivenom production.

Abstract
The observation that the extent of artery calcification correlates with the degree of atherosclerosis was the background for the alternative treatment of cardiovascular disease with chelator ethylenediamine tetraacetate (EDTA). Recent studies have indicated that such chelation treatment has only marginal impact on the course of vascular disease. In contrast, endogenous calcium chelation with removal of calcium from the cardiovascular system paralleled by improved bone mineralization exerted, i.e., by matrix Gla protein (MGP) and osteocalcin, appears to significantly delay the development of cardiovascular diseases. After post-translational vitamin-K-dependent carboxylation of glutamic acid residues, MGP and other vitamin-K-dependent proteins (VKDPs) can chelate calcium through vicinal carboxyl groups. Dietary vitamin K is mainly provided in the form of phylloquinone from green leafy vegetables and as menaquinones from fermented foods. Here, we provide a review of clinical studies, addressing the role of vitamin K in cardiovascular diseases, and an overview of vitamin K kinetics and biological actions, including vitamin-K-dependent carboxylation and calcium chelation, as compared with the action of the exogenous (therapeutic) chelator EDTA. Consumption of vitamin-K-rich foods and/or use of vitamin K supplements appear to be a better preventive strategy than EDTA chelation for maintaining vascular health.

Abstract
Iron is essential for all organisms and cells. Diseases of iron imbalance affect billions of patients, including those with iron overload and other forms of iron toxicity. Excess iron load is an adverse prognostic factor for all diseases and can cause serious organ damage and fatalities following chronic red blood cell transfusions in patients of many conditions, including hemoglobinopathies, myelodyspasia, and hematopoietic stem cell transplantation. Similar toxicity of excess body iron load but at a slower rate of disease progression is found in idiopathic haemochromatosis patients. Excess iron deposition in different regions of the brain with suspected toxicity has been identified by MRI T2* and similar methods in many neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease. Based on its role as the major biological catalyst of free radical reactions and the Fenton reaction, iron has also been implicated in all diseases associated with free radical pathology and tissue damage. Furthermore, the recent discovery of ferroptosis, which is a cell death program based on free radical generation by iron and cell membrane lipid oxidation, sparked thousands of investigations and the association of iron with cardiac, kidney, liver, and many other diseases, including cancer and infections. The toxicity implications of iron in a labile, non-protein bound form and its complexes with dietary molecules such as vitamin C and drugs such as doxorubicin and other xenobiotic molecules in relation to carcinogenesis and other forms of toxicity are also discussed. In each case and form of iron toxicity, the mechanistic insights, diagnostic criteria, and molecular interactions are essential for the design of new and effective therapeutic interventions and of future targeted therapeutic strategies. In particular, this approach has been successful for the treatment of most iron loading conditions and especially for the transition of thalassemia from a fatal to a chronic disease due to new therapeutic protocols resulting in the complete elimination of iron overload and of iron toxicity.

Abstract
In recent years, cyclodextrin polymeric nanoparticles have been designed to introduce new properties and extend their medical applications. Based on the features of cyclodextrins, we derivatized cross-linked cyclodextrin polymers with histidine or carcinine moieties. We found that amylases do not hydrolyze cyclodextrin polymers. The new polymers can form copper(II) complexes and may act as nanochelators to counteract copper(II) dyshomeostasis-related diseases. Furthermore, the copper(II) complexes show superoxide dismutase activity, similar to free carcinine and histidine complexes. The antioxidant biological activity of the copper(II) complex formed in situ may protect cells from oxidative damage related to copper dyshomeostasis.

Abstract
Chronic exposure to arsenic (As) compounds leads to its accumulation in the body, with skin lesions and cancer being the most typical outcomes. Treating As-induced diseases continues to be challenging as there is no specific, safe, and efficacious therapeutic management. Therapeutic and preventive measures available to combat As toxicity refer to chelation therapy, antioxidant therapy, and the intake of natural dietary compounds. Although chelation therapy is the most commonly used method for detoxifying As, it has several side effects resulting in various toxicities such as hepatotoxicity, neurotoxicity, and other adverse consequences. Drugs of plant origin and natural dietary compounds show efficient and progressive relief from As-mediated toxicity without any particular side effects. These natural compounds have also been found to aid the elimination of As from the body and, therefore, can be more effective than conventional therapeutic agents in ameliorating As toxicity. This review provides an overview of the recently updated knowledge on treating As poisoning through natural dietary compounds. This updated information may serve as a basis for defining novel prophylactic and therapeutic formulations.

Abstract
Arsenic toxicity is a major concern due to its deleterious consequences for human health. Rapid industrialization also has weakened the quality of the environment by introducing pollutants that may disrupt balanced ecosystems, adversely and irreversibly impacting humans, plants, and animals. Arsenic, an important toxicant among all environmental hazards, can lead to several detrimental effects on cells and organs, impacting the overall quality of life. Nevertheless, arsenic also has a rich history as a chemotherapeutic agent used in ancient days for the treatment of diseases such as malaria, cancer, plague, and syphilis when other chemotherapeutic agents were yet to be discovered. Arsenicosis-mediated disorders remain a serious problem due to the lack of effective therapeutic options. Initially, chelation therapy was used to metabolically eliminate arsenic by forming a complex, but adverse effects limited their pharmacological use. More recently, plant-based products have been found to provide significant relief from the toxic effects of arsenic poisoning. They act by different mechanisms affecting various cellular processes. Phytoconstituents such as curcumin, quercetin, diallyl trisulfide, thymoquinone, and others act via various molecular pathways, primarily by attenuating oxidative damage, membrane damage, DNA damage, and proteinopathies. Nonetheless, most of the phytochemicals reviewed here protect against the adverse effects of metal or metalloid exposure, supporting their consideration as alternatives to chelation therapy. These agents, if used prophylactically and in conjunction with other chemotherapeutic agents, may provide an effective approach for management of arsenic toxicity. In a few instances, such strategies like coadministration of phytochemicals with a known chelating agent have led to more pronounced elimination of arsenic from the body with lesser off-site adverse effects. This is possible because combination treatment ensures the use of a reduced dose of chelating agent with a phytochemical without compromising treatment. Thus, these therapies are more practical than conventional therapeutic agents in ameliorating arsenic-mediated toxicity. This review summarizes the potential of phytochemicals in alleviating arsenic toxicity on the basis of available experimental and clinical evidence.

Abstract
By altering auxiliary nitrogen-donor ligands, two novel coordination polymers (CPs) containing Cu(II) formulated as [Cu2.5(L)(trz)2(H2O)2]·2H2O (1) (Htrz = 1,2,4-triazole and H3L = 5-(4-carboxybenzyloxy)isophthalic acid) and [Cu(HL)(Hbiz)] (2, Hbiz = benzimidazole) have been produced under the hydrothermal conditions. The complex 2 with both acidic and basic sites was investigated as heterogeneous catalyst, which reveals highly efficient catalytic property of the Knoevenagel condensation reaction. Dynamic changes of coagulation parameters during atherosclerosis was also explored via detecting activated partial thromboplastin time (APTT) and prothrombin time (PT), and the results showed that compared with CP 2, CP 1 has a stronger improvement on the coagulation parameters during atherosclerosis. Then, the high-sensitivity C-reactive protein and matrix metalloproteinase-1 released by the atherosclerotic segment was detected with enzyme linked immunosorbent assay (ELISA) detection, which also revealed that CP 1 could obviously decrease the inflammatory mediator released by the atherosclerotic segment, but not CP 2. And, the cyclooxygenase-2 (COX-2) relative expression level in vascular endothelial cells was detected via the real time RT-PCR. The results of the real time reverse transcription-polymerase chain reaction (RT-PCR) indicated that CP 1 has stronger activity on inhibiting the Notch signaling pathway than CP 2. Finally, we got this information, CP 1 has excellent application values on the coagulation parameters during atherosclerosis via regulating the expression of the COX-2 in vascular endothelial cells.

The removal of excessive blood lead ions (Pb2+) is very important to human health, but current effective removal technology is still lacking because of the complex existence state of Pb2+ in blood, which can be attributed to the fact that most of the blood Pb2+ is combined with haemoglobin (Hb) located in red blood cells (RBCs). Here, a new type of magnetic mesoporous silica/ε-polylysine nanomotor-based remover (MMS/P NR) with abundant chelation sites was designed, synthesized and used to remove Pb2+ from blood. The magnetic core can make the nanocomposites become nanomotors with autonomous movement under an external variable magnetic field, which can effectively improve the contact probability between the MMS/P NRs and Pb2+-contaminated Hb in RBCs. The amino rich ε-polylysine (ε-PL) was used as the co-template of mesoporous silica. Mesoporous channels can provide a confinement effect for Pb2+-contaminated Hb to stabilize the captured blood Pb2+. The movement behavior of the MMS/P NRs in and out of RBCs and the capture mechanism of Pb2+ in the blood were studied. The results indicate that the MMS/P NRs we propose have good blood compatibility, low cytotoxicity, magnetic properties, autonomous movement ability and recyclability under the condition of an external magnetic field. Moreover, compared with the experimental conditions without an external variable magnetic field (0.01485 mg g-1), the MMS/P NRs show a higher blood Pb2+ removal ability under the condition of an external variable magnetic field (0.05525 mg g-1). The design strategy of this remover based on nanomotor technology has great potential in the future medical treatment of heavy metal poisoning.

Abstract
Elevated levels of reactive oxygen species (ROS) are implicated in the onset and progression of many diseases, e.g., virus infection, ischemic stroke and neurodegenerative diseases. ROS-scavenging nanomaterials have attracted particular interest. Here, we report the development of a natural protein nanocage named Dps for in vitro and in vivo antioxidant treatment by inhibiting the Fenton reaction, a critical step in ROS generation and interconversion. Systematic surface engineering enabled cell penetration, good colloidal stability, and facile purification of Dps. With its intrinsic ferroxidase activity consuming both H2O2 and Fe2+, Dps not only protects human cells from oxidative stress but also effectively alleviates ROS-induced inflammation in a mouse dermatitis model. The protection is triggered by elevated H2O2 and thereby, in principle, avoids ROS imbalances. Thus, Dps has potential as a new bionano platform for different purposes, such as antiaging, anti-inflammation and cosmetics.

Abstract
A new Cu(II) coordination polymer (CP) of [Cu5(µ3-OH)2(bcpt)4(bib)2] (1, bib = 1,4-bis(1-imidazoly)benzene and H2bcpt = 3,5-bis(3'-carboxyphenyl)-1,2,4-triazole) was synthesized by reaction of Cu(NO3)2·3H2O reacting with 3,5-bis(3'-carboxyphenyl)-1,2,4-triazole in the existence of 1,4-bis(1-imidazoly)benzene as the second ligand. The treatment activity of the compound on influenza A virus induced chronic obstructive pulmonary disease (COPD) was evaluated. First, the biological function of the lung was assessed by measuring the partial pressure for the carbon dioxide (PaCO2) and oxygen (PaO2) via the analysis of blood gas. Next, the inflammatory cytokines released by alveolar epithelial cells were determined via the ELISA test kit. In addition to this, the real-time RT-PCR was carried out to determine the inflammatory response relative expression in the alveolar epithelial cells. Finally, the relative expression of the TLR3 on the alveolar epithelial cells was revealed by western blot. Possible binding patterns were acquired from the post scoring software and molecular docking, which exhibited two possible functional side chain binding sites of TLR3 to compounds binding, possibly offering distinct regulatory mechanisms.

Abstract
Iron and ascorbic acid (vitamin C) are essential nutrients for the normal growth and development of humans, and their deficiency can result in serious diseases. Their interaction is of nutritional, physiological, pharmacological and toxicological interest, with major implications in health and disease. Millions of people are using pharmaceutical and nutraceutical preparations of these two nutrients, including ferrous ascorbate for the treatment of iron deficiency anaemia and ascorbate combination with deferoxamine for increasing iron excretion in iron overload. The main function and use of vitamin C is its antioxidant activity against reactive oxygen species, which are implicated in many diseases of free radical pathology, including biomolecular-, cellular- and tissue damage-related diseases, as well as cancer and ageing. Ascorbic acid and its metabolites, including the ascorbate anion and oxalate, have metal binding capacity and bind iron, copper and other metals. The biological roles of ascorbate as a vitamin are affected by metal complexation, in particular following binding with iron and copper. Ascorbate forms a complex with Fe3+ followed by reduction to Fe2+, which may potentiate free radical production. The biological and clinical activities of iron, ascorbate and the ascorbate–iron complex can also be affected by many nutrients and pharmaceutical preparations. Optimal therapeutic strategies of improved efficacy and lower toxicity could be designed for the use of ascorbate, iron and the iron–ascorbate complex in different clinical conditions based on their absorption, distribution, metabolism, excretion, toxicity (ADMET), pharmacokinetic, redox and other properties. Similar strategies could also be designed in relation to their interactions with food components and pharmaceuticals, as well as in relation to other aspects concerning personalized medicine.

Abstract
Arsenic (As) is widely used in the modern industry, especially in the production of pesticides, herbicides, wood preservatives, and semiconductors. The sources of As such as contaminated water, air, soil, but also food, can cause serious human diseases. The complex mechanism of As toxicity in the human body is associated with the generation of free radicals and the induction of oxidative damage in the cell. One effective strategy in reducing the toxic effects of As is the usage of chelating agents, which provide the formation of inert chelator–metal complexes with their further excretion from the body. This review discusses different aspects of the use of metal chelators, alone or in combination, in the treatment of As poisoning. Consideration is given to the therapeutic effect of thiol chelators such as meso-2,3-dimercaptosuccinic acid, sodium 2,3-dimercapto-1-propanesulfonate, 2,3-dimercaptopropanol, penicillamine, ethylenediaminetetraacetic acid, and other recent agents against As toxicity. The review also considers the possible role of flavonoids, trace elements, and herbal drugs as promising natural chelating and detoxifying agents.

Abstract
We report in this paper an unusual β-cyclodextrin mediated-aluminum (III) ion sensing based on augmented quenching of fluorescence. The fluorescent sensing of metal ions by a new ligand prepared (L = 4-[{4-(1H-imidazol-1-yl)phenyl]imino}methyl]piperazine-1-carboxaldehyde) has been investigated as well as the effect of the supramolecular complex formation with β-CD. In aqueous solution, L shows an increase of fluorescence due to the interaction with β-cyclodextrin with a formation constant of 77 (± 12) M-1. The ROESY NMR spectrum clearly indicates that L is encapsulated by β-CD. Theoretical calculations show the possible structure both of the L-β-CD adduct and of the coordination mode of Al3+ ion to L. In the presence of β-CD, the piperazine adopts a distorted conformation. It leads to an enhanced Al3+ sensing by the compound in its supramolecular complexed form. The lower limit of detection of Al3+ ions is 6.00 × 10-8 mol L-1. This detection limit slightly expands for L in the presence of β-CD.

Abstract
The potential neurotoxic role of Al(iii) and its proposed link with the insurgence of Alzheimer's Disease (AD) have attracted increasing interest towards the determination of the nature of bioligands that are propitious to interact with aluminum. Among them, catecholamine-based neurotransmitters have been proposed to be sensitive to the presence of this non-essential metal ion in the brain. In the present work, we characterize several aluminum-catecholamine complexes in various stoichiometries, determining their structure and thermodynamics of formation. For this purpose, we apply a recently validated computational protocol with results that show a remarkably good agreement with the available experimental data. In particular, we employ Density Functional Theory (DFT) in conjunction with continuum solvation models to calculate complexation energies of aluminum for a set of four important catecholamines: l-DOPA, dopamine, noradrenaline and adrenaline. In addition, by means of the Quantum Theory of Atoms in Molecules (QTAIM) and Energy Decomposition Analysis (EDA) we assessed the nature of the Al-ligand interactions, finding mainly ionic bonds with an important degree of covalent character. Our results point at the possibility of the formation of aluminum-catecholamine complexes with favorable formation energies, even when proton/aluminum competition is taken into account. Indeed, we found that these catecholamines are better aluminum binders than catechol at physiological pH, because of the electron withdrawing effect of the positively-charged amine that decreases their deprotonation penalty with respect to catechol. However, overall, our results show that, in an open biological environment, the formation of Al-catecholamine complexes is not thermodynamically competitive when compared with the formation of other aluminum species in solution such as Al-hydroxide, or when considering other endogenous/exogenous Al(iii) ligands such as citrate, deferiprone and EDTA. In summary, we rule out the possibility, suggested by some authors, that the formation of Al-catecholamine complexes in solution might be behind some of the toxic roles attributed to aluminum in the brain. An up-to-date view of the catecholamine biosynthesis pathway with sites of aluminum interference (according to the current literature) is presented. Alternative mechanisms that might explain the deleterious effects of this metal on the catecholamine route are thoroughly discussed, and new hypotheses that should be investigated in future are proposed.

Abstract
Pb2+ pollution and poisoning are serious environmental and pharmacological concerns. The World Health Organization reported that Pb has resulted in 540,000 deaths in 2016 alone. Therefore, effective drugs or supplements that can alleviate or offset Pb2+-induced toxicity are badly needed. Through screening biocompatible natural compounds, we discovered that chicoric acid exhibited potent protective activities against Pb2+-induced toxicity both in BV-2 microglial cells and in zebrafish from the first days of development. Chicoric acid was able to reduce Pb2+-induced increases in levels of reactive oxygen species and tumor necrosis factor alpha, restoring the cell cycle in BV-2 cells. In the zebrafish model, chicoric acid significantly alleviated the Pb2+-induced serious mortality and malformation of zebrafish larvae in a concentration-dependent manner. These protective activities of chicoric acid were mainly from its alleviation of Pb2+-induced dysregulation of oxidative response pathways, including key genes such as Aox1, Gclm, Hmox1, Nqo1, Scd1, and Srxn1, as well as HO-1 protein. Since Pb2+ is difficult to be completely eliminated from the body and chelating agents may cause serious adverse effects, chicoric acid is likely a potential supplement therapy, in addition to current clinical practices.

Abstract
The indispensable requirement for metals in life processes has led to the evolution of sophisticated mechanisms that allow organisms to maintain dynamic equilibria of these ions. This dynamic control of the level, speciation, and availability of a variety of metal ions allows organisms to sustain biological processes while avoiding toxicity. When functioning properly, these mechanisms allow cells to return to their metal homeostatic set points following shifts in the metal availability or other stressors. These periods of transition, when cells are in a state of flux in which they work to regain homeostasis, present windows of opportunity to pharmacologically manipulate targets associated with metal-trafficking pathways in ways that could either facilitate a return to homeostasis and the recovery of cellular function or further push cells outside of homeostasis and into cellular distress. The purpose of this Viewpoint is to highlight emerging opportunities for chemists and chemical biologists to develop compounds to manipulate metal-trafficking processes for therapeutic benefit.

Abstract
Purpose: This research is devoted to designing the synthesis of sulfanyl-substituted 3,5-dimethylisoxazoles, which contain structural analogues of the SAM drug in the molecule. SAM (S-adenosyl-L-methionine), formed in the biosynthetic process, is used as an effective hepatoprotective drug. Complexation and hepatoprotective properties of the combinatorial series of bis(isoxazolylsulfanyl)ethane have been studied. Methods: Bis(isoxazol-4-ylmethylsulfanyl)alkanes were synthesized using the one-pot method. The structures of compounds were established by one-dimensional (1H,13C) and two-dimensional (COSY, HCQS, HMBC) NMR spectroscopy, mass-spectrometry and X-ray diffraction. The biological activity of the combinatorial series of sulfanyl derivatives of diketones, azoles and their metal complexes has been studied by in vivo method. Simulation of the animal associated processes was carried out in accordance with the principles of bioethics. Screening studies of hepatoprotective activity were carried out in a model of acute CC14 intoxication after a single injection intraperitoneally as a 50% solution in olive oil. The pharmacologically known hepatoprotective drug SAM served as a control. Results: Two-step synthesis of novel α,ω-bis(isoxazol-4-ylmethylsulfanyl)alkanes was carried out via the multicomponent reaction between 2,4-pentandione, CH2O and α,ω-dithiols, then the resulting α,ω-bis(1,3-diketone-2-ylmethylsulfanyl)alkanes were transformed by hydroxyl amine to obtain bis-isoxasole derivatives. Promising precursor 1,2-bis(isoxazol-4-ylmethylsulfanyl)ethane was converted to metal complexes by interaction with PdCl2 or CuCl. The obtained compounds were found to be practically non-toxic compounds (1001 - 3000 mg/kg) according to the classification of K.K. Sidorov, but copper complex refers to low-toxic compounds substances (165 mg/kg). Compounds of sulfanyl ethane series demonstrate hepatoprotective activity. Conclusion: Palladium(II) complex being almost non-toxic possesses hepatoprotective activity comparable to the drug like SAM.

Abstract
Thermodynamic information about the metal-ligand interaction between Fe3+, Zn2+, Cu2+ and Sn2+, and a biodegradable ligand as MGDA is reported. The speciation scheme was obtained by means of potentiometric measurements and isothermal titration calorimetry (to determine enthalpy changes) in NaCl medium. The formation of the ML and MLOH species was evidenced for all the metal cations, and for Fe3+ also the ML2 and ML(OH)2 were found. The relative stability, for the ML species, follows the order: Sn2+ > Fe3+ > Cu2+ > Zn2+. Stability constants and enthalpy changes were obtained at different ionic strengths, and data were modeled using the Debye-Hückel and SIT approaches to obtain data in a standard state. At infinite dilution, the enthalpy changes are largely negative for Cu2+ (-34.1 kJ mol-1) and Sn2+ (-16.6 kJ mol-1), slightly negative for Fe3+ (-3.3 kJ mol-1) and positive for Zn2+ (8.7 kJ mol-1). In all cases, the entropic contribution to the stability is predominant. The sequestering ability of MGDA was evaluated determining the pL0.5 values in different conditions. Comparing the data reported in this work and literature ones, some empirical relationships were obtained with predictive purpose. For example, using 11 data in the test set we have: log K (M/MGDA) ± 0.1 = 1.13 + 0.84·log K (M/NTA) Case studies were built up in the conditions of seawater, fresh water and urine to study the possible use of MGDA towards the metal cations here studied. Some considerations were also done in the light of the ocean acidification.

Abstract
Alkali metal ions play very important roles in all biological systems, some of them are essential for life. Their concentration depends on several physiological factors and is very variable. For example, sodium concentrations in human fluids vary from quite low (e.g., 8.2 mmol dm(-3) in mature maternal milk) to high values (0.14 mol dm(-3) in blood plasma). While many data on the concentration of Na(+) and K(+) in various fluids are available, the information on other alkali metal cations is scarce. Since many vital functions depend on the network of interactions occurring in various biofluids, this chapter reviews their complex formation with phosphates, nucleotides, amino acids, and related ligands of biological relevance. Literature data on this topic are quite rare if compared to other cations. Generally, the stability of alkali metal ion complexes of organic and inorganic ligands is rather low (usually log K < 2) and depends on the charge of the ligand, owing to the ionic nature of the interactions. At the same time, the size of the cation is an important factor that influences the stability: very often, but not always (e.g., for sulfate), it follows the trend Li(+) > Na(+) > K(+) > Rb(+) > Cs(+). For example, for citrate it is: log K ML = 0.88, 0.80, 0.48, 0.38, and 0.13 at 25 °C and infinite dilution. Some considerations are made on the main aspects related to the difficulties in the determination of weak complexes. The importance of the alkali metal ion complexes was also studied in the light of modelling natural fluids and in the use of these cations as probes for different processes. Some empirical relationships are proposed for the dependence of the stability constants of Na(+) complexes on the ligand charge, as well as for correlations among log K values of NaL, KL or LiL species (L = generic ligand).

Understanding the bioavailability and sequestration of different metal cations in the presence of a biodegradable chelant S,S-EDDS in biological fluids and natural waters. CHEMOSPHERE 2016; 150:341-356.

Abstract
Ethylenediamine-N,N'-disuccinic acid is a biodegradable alternative to EDTA, therefore its use for the sequestration of Ca(2+), Sn(2+), Cu(2+), Zn(2+) and Fe(3+) is analyzed. New data on its binding ability towards these cations were obtained with potentiometric, voltammetric and calorimetric measurements at different ionic strengths and at T = 298.15 K. Real multi-component fluids, namely fresh water, urine, sea water, saliva and blood plasma were chosen as case studies to evaluate the sequestering ability of EDDS in comparison with EDTA. Speciation diagrams were drawn in selected conditions, considering all interactions among the "natural" components of the fluid and those studied in this work, EDDS and EDTA (cL = 1 mmol dm(-3)) as sequestering agents and the cited metal cations (cM ∼ 10(-5) mol dm(-3)). The comparison of the sequestering ability of EDDS and EDTA is done using pM and pL0.5. In blood plasma the plasma mobilizing index was adopted. It was found that EDDS is a good alternative to EDTA, which tends to bind Ca(2+) and Mg(2+) more than EDDS. In particular, EDTA cannot be used as a sequestrant for Sn(2+) when cCa > cEDTA. EDDS is more efficient than EDTA at pH < 8, particularly in urine, where carbonate is absent. In sea water, the sequestering ability of EDDS towards Fe(3+) is higher than that of EDTA. In blood plasma, the PMI of EDDS towards Cu(2+) is higher than that of EDTA. Thermodynamic information, in terms of ΔH and ΔS, for the protonation and metal complex formation reactions are reported.
