AB  - The four novel complexes [{cis-PtCl(NH3)2(μ-4,4′ -bipyridyl)ZnCl(terpy)}](ClO4)2 (C1), [{trans-PtCl(NH3)2(μ-
4,4′ -bipyridyl)ZnCl(terpy)}](ClO4)2 (C2), [{cis-PtCl(NH3)2(μ-pyrazine)ZnCl(terpy)}](ClO4)2 (C3) and [{trans-
PtCl(NH3)2(μ-pyrazine)ZnCl(terpy)}](ClO4)2 (C4) (where terpy = 2,2′ :6′ ,2′ ′ -terpyridine) were synthesized and
characterized. Acid–base titrations and concentration dependent kinetic measurements for the reactions with
biologically relevant ligands such as guanosine-5′ -monophosphate (5′ -GMP), inosine-5′ -monophosphate (5′ -IMP)
and glutathione (GSH), were studied at pH 7.4 and 37 ◦C. The binding of the heterometallic bridged cis- or trans-
Pt(II)-Zn(II) complexes to calf thymus DNA (CT-DNA) was studied by UV absorption and fluorescence emission
spectroscopy and molecular docking. The results indicated that the complexes bind strongly to DNA, through
groove binding, hydrogen bonds, and hydrophobic or electrostatic interaction. The possible in vitro DNA protective
effect of cis- and trans-Pt-L-Zn complexes has shown that C3 had significant dose-dependent DNA-protective
effect and the same ability to inhibit peroxyl as well as hydroxyl radicals. Antiproliferative effect of the
complexes, mRNA expression of apoptosis and repair-related genes after treatment in cancer cells indicated that
newly synthesized C2 exhibited highly selective cytotoxicity toward colon carcinoma HCT116 cells. Only
treatment with trans analog C2 induced effect similar to the typical DNA damaging agent such as cisplatin,
characterized by p53 mediated cell response, cell cycle arrest and certain induction of apoptotic related genes.
Both cis- and trans-isomers C1 and C2 showed potency to elicit expression of PARP1 mRNA and in vitro DNA
binding.

AB  - Rhenium complexes merit particular attention in the area of metallodrug design due to
rhenium’s broad spectrum of oxidation states and consequently, the possibility to design
compounds of great structural diversity [1,2]. Thus, the synthesis, chemical characterization,
and antitumor activity in vitro of the six Re(V) complexes are described. Novel compounds
were obtained via reaction of [ReOCl3(PPh3)2] with corresponding ligands (pyridine-2-
carboxylic acid, 3-methylpyridine-2-carboxylic acid, 6-methylpyridine-2-carboxylic acid, 2,3-
pyridinedicarboxylic acid, 2,5-pyridinedicarboxylic acid, and 2,6-pyridinedicarboxylic acid) in
acetonitrile or dichloromethane/methanol at 78 °C for 3h. The complexes were fully
characterized using NMR, IR, MS, and elemental analysis. Results of X-ray diffraction analysis
for three of these compounds confirmed the proposed octahedral geometry with bidentate
coordinated ligands, via both oxygen and nitrogen atoms. The antiproliferative effect was
determined by MTT assay. All complexes expressed moderate to low cytotoxic potential.
Complex with pyridine-2-carboxylic acid showed dose-dependent cytotoxic potential,
particularly toward triple-negative breast adenocarcinoma cells MDA-MB-231 and pancreatic
adenocarcinoma cells PANC-1. Drug combination studies in PANC-1 cells with that complex
and Verapamil hydrochloride (VRP) showed a slight arrest of the cell cycle in the S phase and
also increase its antiproliferative potential.

AB  - Metal-based compounds are rarely good antimicrobial compounds. Here we report
synthesis, chemical characterization and antimicrobial potency of fourteen Ru(II) arene
complexes with pyridine-based ligands. The structures and purity of synthesized
compounds were confirmed using 1H and 13C NMR spectroscopy, IR spectroscopy, MS, and
EA. A micro-well dilution assay was used to determine the minimum inhibitory

Streptomycin and chloramphenicol were used as a positive control. The best activity of all
tested bacteria was observed against E. coli, with a MIC value of 1.25 mg/mL, for
complexes with 2,4- i 2,5-pyridinedicarboxylic ligands. Also, all synthesized complexes
showed the same activity against C. Albicans.

AB  - Ruthenium complexes with dipyrido[3,2-a:2’,3’-c]phenazine (dppz) ligands have been
extensively investigated as potential anticancer agents due to possibility of modulation of their
intracellular accumulation and respective anticancer mechanism of action [1,2]. In recent years
we have explored the anticancer activity of a variety of ruthenium(II)-arene complexes with
dppz based ligands and some of them demonstrated remarkable cytotoxic activity [3].
Following these studies here we present a series of Ru(II)-arene complexes with the general
formula [(η6-arene)Ru(dppz-R)Cl]PF6, where arene fragment was benzene, toluene or pcymene and R was -NO2, -Me or -COOMe with aim to study influence of both of half-sandwich
Ru(II)-arene fragments and the variation of dppz ligands on improvement of the therapeutic
potential of those complexes. All compounds were fully characterized by physico-chemical
methods. The anticancer activity of dppz ligands and respective Ru complexes was assessed
against MDA-MB-231, HCT116 and CT26 cancer cell lines and healthy MRC5 lung
fibroblasts. In vivo efficacy of lead Ru-dppz complex revealed significantly reduction of tumor
burden in mice with colorectal cancers without inducing liver and kidney toxicity. Thus, all the
results indicated that introducing appropriate dppz into ruthenium-arene scaffold was a
promising strategy for developing potent antitumor agents.

AB  - Despite extensive research on the anticancer properties of Ru
complexes with dipyrido[3,2-a:2′,3′-c]phenazine (dppz) ligands, their in vivo
efficacy is rarely investigated. Aiming to understand whether the coordination of
certain half-sandwich Ru(II)-arene fragments might improve the therapeutic
potential of dppz ligands, we prepared a series of Ru(II)-arene complexes with
the general formula [(η6-arene)Ru(dppz-R)Cl]PF6, where the arene fragment
was benzene, toluene, or p-cymene and R was -NO2, -Me, or -COOMe. All
compounds were fully characterized by 1H and 13C NMR spectroscopy and high-
resolution ESI mass-spectrometry, and their purity was verified by elemental
analysis. The electrochemical activity was investigated using cyclic voltammetry.
 The anticancer activity of dppz ligands and their respective Ru complexes was
assessed against several cancer cell lines, and their selectivity toward cancer cells
was assessed using healthy MRC5 lung fibroblasts. The substitution of benzene
with a p-cymene fragment resulted in a more than 17-fold increase of anticancer
activity and selectivity of Ru complexes and significantly enhanced DNA degradation in HCT116 cells. All Ru complexes were electrochemically active in the biologically accessible redox window and were shown to markedly induce the production of ROS in mitochondria. The lead Ru-dppz complex significantly reduced tumor burden in mice with colorectal cancers without inducing liver
 and kidney toxicity.

AB  - Despite extensive research on the anticancer properties of Rucomplexes with dipyrido[3,2-a:2′,3′-c]phenazine (dppz) ligands, their in vivoefficacy is rarely investigated. Aiming to understand whether the coordination ofcertain half-sandwich Ru(II)-arene fragments might improve the therapeuticpotential of dppz ligands, we prepared a series of Ru(II)-arene complexes withthe general formula [(η6-arene)Ru(dppz-R)Cl]PF6, where the arene fragmentwas benzene, toluene, or p-cymene and R was -NO2, -Me, or -COOMe. Allcompounds were fully characterized by 1H and 13C NMR spectroscopy and high-resolution ESI mass-spectrometry, and their purity was verified by elementalanalysis. The electrochemical activity was investigated using cyclic voltammetry. The anticancer activity of dppz ligands and their respective Ru complexes wasassessed against several cancer cell lines, and their selectivity toward cancer cellswas assessed using healthy MRC5 lung fibroblasts. The substitution of benzenewith a p-cymene fragment resulted in a more than 17-fold increase of anticanceractivity and selectivity of Ru complexes and significantly enhanced DNA degradation in HCT116 cells. All Ru complexes were electrochemically active in the biologically accessible redox window and were shown to markedly induce the production of ROS in mitochondria. The lead Ru-dppz complex significantly reduced tumor burden in mice with colorectal cancers without inducing liver and kidney toxicity.

AB  - Eleven new and three reported half-sandwich Ru(II) arene complexes were synthesized using [Ru(g6-benzene)Cl(l-Cl)]2 and
[Ru(g6-toluene)Cl(l-Cl)]2 and four pyridine carboxylic acid-based
ligands (dicarboxylic acids and halogen derivatives). The structures
and purity of synthesized compounds were confirmed using 1H
and 13C NMR spectroscopy, infrared spectroscopy, mass spectrometry, and elemental analysis. The stability of synthesized compounds in dimethyl sulfoxide solution was confirmed using 1H
NMR spectroscopy. The seven ligands, two complex precursors
(CP1 and CP2), and 14 half-sandwich Ru(II) picolinate complexes
(C1–C14) were evaluated for in vitro antibacterial and antifungal
activity against pathogens, such as Staphylococcus aureus, Bacillus
cereus, Proteus mirabilis, Klebsiella pneumoniae, Ecsherichia coli,
Pseudomonas aeruginosa, Salmonella enteritidis, Enterobacter aerogenes, and yeast Candida albicans, using the microwell-dilution
method. Among the tested samples, the ligands showed better
inhibitory effect against Gram-positive bacteria when compared
to the metal complexes. The most susceptible Gram-negative bacteria was Ecsherichia coli, with a MIC value of 1.25 mg/mL, for C3,
C6, and C10. All synthesized complexes showed similar, slightly
better activity against Candida albicans.

Crystal structures of all three complexes havebeen additionally confirmed by X-ray analysis. The biological activity has been investigated in the panel of tumorcell lines A549, PANC-1, MDA-MB-231, MCF-7, LS-174, EAhy.926 and one in non-tumor cell line MRC-5. OnlyC1 showed dose-dependent cytotoxic potential, particularly toward triple-negative breast adenocarcinoma cellsMDA-MB-231 with IC50 68.90 ± 1.73 μM and pancreatic adenocarcinoma cells PANC-1 with IC50 69.84 ± 2.3μM. Both cell lines are characterized by a highly invasive and resistant phenotype. Drug combination studies inPANC-1 cells with C1 and Verapamil hydrochloride (VRP), which is the established inhibitor of efflux transporterP-glycoprotein (Pgp), revealed enhancement of antiproliferative action of the complex in a dose-dependentmanner, and slight arrest of cell cycle in the S phase. Also, a depletion of the glutathione (GSH) level by Lbuthionine-sulfoximine (L-BSO) at sub-toxic concentrations (100 μM) caused an increase of activity of C1 to theIC50 57.67 ± 6.51 (μM). A morphological analysis in PANC-1 cells by dual acridine orange/ethidium bromidestaining, revealed apoptotic potential of complex C1 and a slower kinetic of cell death induction, suggesting adifferent mechanism of action compared to cisplatin.

AB  - Rhenium complexes merit particular attention in the area of metallodrug design due to rhenium’s broad spectrum of oxidation states and consequently, the possibility to design compounds of a great structural diversity. Thus, the synthesis, chemical characterization and antitumor activity in vitro of the three Re(V) complexes is described. Novel compounds were obtained via reaction of [ReOCl3(PPh3)2] with corresponding ligands (pyridine-2-carboxylic acid, 3-methylpyridine-2-carboxylic acid and 6-methylpyridine-2-carboxylic acid) in acetonitrile at 78 °C for 3h. The complexes were fully characterized using NMR, IR, MS and elemental analysis. Their octahedral geometry with bidentate NO ligand was confirmed by X-ray diffraction analysis. Antiproliferative effect was determined by MTT assay and only the complex with pyridine-2-carboxylic acid (1) showed dose-dependent cytotoxic potential, particularly toward triple-negative breast adenocarcinoma cells MDA-MB-231 with IC50 68.90 ± 1.73 µM and pancreatic adenocarcinoma cells PANC-1 with IC50 69.8 ± 2.3 µM. Drug combination studies in PANC-1 cells with 1 and Verapamil hydrochloride (VRP) showed slight arrest of cell cycle in the S phase and also it increase its antiproliferative potential to IC50 51.4 ± 2.8 μM. Part of the research included a depletion of the glutathione (GSH) level by L-buthionine-sulfoximine (L-BSO) at sub-toxic concentrations (100 μM) in PANC-1 cells which caused an increase of activity of 1 to the IC50 57.67 ± 6.51 μM.

AB  - Three ruthenium-bipyridine complexes (1–3) carrying acetylpyridine ligand unit were synthesized in methanol via the reaction of [RuCl2(bpy)2] with corresponding acetylpyridine (2-, 3-, and 4-acpy). Obtained complexes were characterized by (1H and 13C) NMR and IR spectroscopy, MS spectrometry, UV‒vis spectrophotometry, and cyclic voltammetry. Their structural characterization revealed bidentate coordination mode for 2-acpy while 3- and 4-acpy acted as monodentate ligands. The electrochemical profile of newly synthesized compounds was investigated by cyclic voltammetry which confirmed their electrochemical activity. Voltammetric responses within the −1.20 < Ep < 1.50 V range of potentials were summarized in two major events: Ru(II)→Ru(III) oxidation spotted at app. ΔEp = 0.65 V and successive reductions of bpy units located from ‒0.79 V to 0.47 V (vs. Ag/AgCl (3 M) electrode). The DNA-binding activity of the complexes was evaluated by both UV‒vis spectrophotometry and cyclic voltammetry indicating DNA-intercalation with a slight contribution of electrostatic interactions. Furthermore, antimicrobial activity was tested against bacterial and fungal strains, for which moderate activity was observed. Assessment of in vitro toxicity against freshly hatched nauplii of Artemia salina as well as radical scavenging capacity was evaluated. The test compounds showed neither toxicity nor antioxidant activity.

AB  - Ruthenium complexes are of significant interest in the treatment of malignancies. Ru(II)
complexes with N-alkylphenothiazines (chlorpromazine, trifluoperazine, and thioridazine)
were used in the study of possible apoptosis pathways in K562 cells.
Spectrophotometrically extracellular LDH was quantified and immunochemical expression
of COX-2, t-JNK, p-JNK and -actin after SDS electrophoresis was determined. The
Ru(II) complex with trifluoperazine at a concentration of 10 μM reduced t-JNK
expression, inhibited COX-2 by about 42%, significantly increased the amount of
extracellular LDH compared to the untreated K562 cells and thus confirmed apoptosis.

for different applications related to e.g. homogenous catalysis, cancer therapy, tumor
diagnosis, and advanced materials.1 Thus, the synthesis and full (electro)chemical
characterization of three new Ru(II) complexes carrying acetylpyridine (acpy) ligand unitis
is described. The complexes were obtained via reaction of three ligand equivalents (2-, 3-,

After the overnight reflux, the reaction mixture was left to cool when equimolar amount of
NH4PF6 was added. The products were isolated in a form of dark red powder. The
complexes were characterized by IR, NMR and MS revealing bidentate coordination of 2-
acpy and monodentate binding of 3- and 4-acpy. Their electrochemical profile was studied
by cyclic voltammetry which confirmed rich redox chemistry.

complexes interfere with intercalator ethidium bromide
and minor groove binder Hoechst 33258 by a singular
non-intercalative mode with extent that differs by two
orders of magnitude. Gel electrophoresis results on DNA cleavage assay demonstrated that all complexes
produced conformational changes of supercoiled
circular plasmid pUC19 in concentration dependent
way. The results of fluorescence titration bovine
serum albumin by 1, 2, 3 and 4 showed that all complexes
significantly quench tryptophan residues fluorescence
through a static quenching mechanism. The
antimicrobial activity against both Gram-positive and
Gram-negative bacteria analyzed. Complex 1 was most
active, even on Escherichia coli was more active than

AB  - Discover a new class of ruthenium-based complexes that were investigated as potential antimicrobial agents: dinuclear polypyridil ruthenium(II) complexes exhibited excellent growth inhibition, and Ru(II) arene complexes with acetyl pyridine ligands exhibited moderate antimicrobial activity in the panel of bacteria1. Here we have synthesized 14 new Ru(II) arene complexes with pyridine-based ligands and examined their antimicrobial potency, trying to correlate their structure and biological activity. Reported complexes were obtained in a reaction of [Ru(η6-benzene)Cl(μ-Cl)]2 or [Ru(η6-toluene)Cl(μ-Cl)]2 with halogen derivatives of picolinic acid or pyridine dicarboxylic acids in a 1:2 molar ratio in ethanol. The complexes were soluble in DMSO and water. Their structural characterization included IR and NMR spectroscopy and MS spectrometry, and purity was confirmed by elemental analysis. In this report, we demonstrate the activities of these novel compounds against six typical gram-negative and two gram-positive bacteria. A micro-well dilution assay was used to determine the minimum inhibitory concentration (MIC), and minimum bactericidal concentration. Streptomycin and chloramphenicol, commercial antibiotics, were used as a positive control. The best activity of all tested bacteria was observed against E. coli, with a MIC value of 1.25 mg/mL, for C3, C6, and C10 complexes. Also, all synthesized complexes showed the same activity against C. albicans.

AB  - Three Re(V) complexes of structural formulas [ReOCl2L(PPh3)], where L is pyridine-2-carboxylic acid (C1), 3-
methyl-pyridine-2-carboxylic acid (C2) and 6-methyl-pyridine-2-carboxylic acid (C3) were synthesized and
characterized using NMR, IR spectroscopy and mass spectrometry. Crystal structures of all three complexes have
been additionally confirmed by X-ray analysis. The biological activity has been investigated in the panel of tumor
cell lines A549, PANC-1, MDA-MB-231, MCF-7, LS-174, EAhy.926 and one in non-tumor cell line MRC-5. Only
C1 showed dose-dependent cytotoxic potential, particularly toward triple-negative breast adenocarcinoma cells
MDA-MB-231 with IC50 68.90 ± 1.73 μM and pancreatic adenocarcinoma cells PANC-1 with IC50 69.84 ± 2.3
μM. Both cell lines are characterized by a highly invasive and resistant phenotype. Drug combination studies in
PANC-1 cells with C1 and Verapamil hydrochloride (VRP), which is the established inhibitor of efflux transporter
P-glycoprotein (Pgp), revealed enhancement of antiproliferative action of the complex in a dose-dependent
manner, and slight arrest of cell cycle in the S phase. Also, a depletion of the glutathione (GSH) level by Lbuthionine-sulfoximine (L-BSO) at sub-toxic concentrations (100 μM) caused an increase of activity of C1 to the
IC50 57.67 ± 6.51 (μM). A morphological analysis in PANC-1 cells by dual acridine orange/ethidium bromide
staining, revealed apoptotic potential of complex C1 and a slower kinetic of cell death induction, suggesting a
different mechanism of action compared to cisplatin.

AB  - Pyridine (carboxylate) type of molecules has been intensively studied since early 2000s as it provides diverse design capabilities in terms of coordination to metal ions. Several structural motifs featuring mono-, bi-, and pentadentate binding modes are discussed in a combination with a variety of different substituents with the pyridine unit. In this context, the current review underlines a brief summary of advances on metal complexes with pyridine-based ligands aimed for further development as metallodrug. In line with this, we also highlight their key properties, different synthetic strategies employed in the preparation, and possible structure–property correlations, indicating advantages and limitations of the applied methods used within documented studies.

AB  - The reactions of four cymene-capped ruthenium(II) compounds with pro-apaptotic protein, cytochrome c (Cyt), and anti-proliferating protein lysozyme (Ly) in carbonate buffer were investigated by ESI-MS, UV–Vis absorption and CD spectroscopy. The complexes with two chloride ligands (C2 and C3) were more reactive toward proteins than those with only one (C1 and C4), and the complex with S,N-chelating ligand (C4) was less reactive than one with O,N-chelating ligand (C1). Dehalogenated complexes are most likely species initially coordinating proteins for all tested complexes. During the time, protein adducts vividly exchanged non-arene organic ligand L with CO32- and OH-, while cymene moiety was retained. In water, only dehalogenated adducts were identified suggesting that in vivo, in the presence of various anions, dynamic ligand exchange could generate different intermediate protein species. Although all complexes reduced Cyt, the reduction was not dependent on their reactivity to protein, implying that initially noncovalent binding to Cyt occures, causing its reduction, followed by coordination to protein. Cyt reduction was accompanied with rupture of ferro-Met 80 and occupation of this hem coordination site by a histidine His-33/26. Therefore, in Cyt with C2 and C3 less intensive reduction of hem iron leave more unoccupied target residues for Ru coordination, leading to more efficient formation of covalent adducts, in comparison to C1 and C4. This study contribute to development of new protein-targeted Ru(II) cymene complexes, and to design of new cancer therapies based on targeted delivery of Ru(II) arene complexes bound on pro-apoptotic/anti-proliferating proteins as vehicles.

AB  - Inhibitors of poly(ADP-ribose) polymerase-1 (PARP-1) showed remarkable clinical efficacy in BRCA-mutated tumors. Based on the rational drug design, derivatives of PARP inhibitor 3-aminobenzamide (3-AB), 2-amino-4-methylbenzamide (L1) and 3-amino-N-methylbenzamide (L2), were coordinated to the ruthenium(II) ion, to form potential drugs affecting DNA and inhibiting PARP enzyme. The four conjugated complexes of formula: C1 [(ƞ6-toluene)Ru(L1)Cl]PF6, C2 [(ƞ6-p-cymene)Ru(L1)Cl]PF6, C3 [(ƞ6-toluene)Ru(L2)Cl2] and C4 [(ƞ6-p-cymene)Ru(L2)Cl2], have been synthesized and characterized. Colorimetric 3-(4.5-dimethylthiazol-2-yl)-2.5-diphenyltetrazolium bromide (MTT) assay showed the highest antiproliferative activity of C1 in HCC1937, MDA-MB-231, and MCF-7 breast cancer cells. Efficiency of inhibition of PARP-1 enzymatic activity in vitro decreased in order: C2 > C4 > 3-AB>C1 > C3. ICP-MS study of intracellular accumulation and distribution in BRCA1-mutated HCC1937 revealed that C1-C4 entered cells within 24 h. The complex C1 showed the highest intracellular accumulation, nuclear-targeting properties, and exhibited the highest DNA binding (39.2 ± 0.6 pg of Ru per μg of DNA) that resulted in the cell cycle arrest in the S phase.

AB  - The reactions of four cymene-capped ruthenium(II) compounds with pro-apaptotic protein, cytochrome c (Cyt), and anti-proliferating protein lysozyme (Ly) in carbonate buffer were investigated by ESI-MS, UV–Vis absorption and CD spectroscopy. The complexes with two chloride ligands (C2 and C3) were more reactive toward proteins than those with only one (C1 and C4), and the complex with S,N-chelating ligand (C4) was less reactive than one with O,N-chelating ligand (C1). Dehalogenated complexes are most likely species initially coordinating proteins for all tested complexes. During the time, protein adducts vividly exchanged non-arene organic ligand L with CO32- and OH-, while cymene moiety was retained. In water, only dehalogenated adducts were identified suggesting that in vivo, in the presence of various anions, dynamic ligand exchange could generate different intermediate protein species. Although all complexes reduced Cyt, the reduction was not dependent on their reactivity to protein, implying that initially noncovalent binding to Cyt occures, causing its reduction, followed by coordination to protein. Cyt reduction was accompanied with rupture of ferro-Met 80 and occupation of this hem coordination site by a histidine His-33/26. Therefore, in Cyt with C2 and C3 less intensive reduction of hem iron leave more unoccupied target residues for Ru coordination, leading to more efficient formation of covalent adducts, in comparison to C1 and C4. This study contribute to development of new protein-targeted Ru(II) cymene complexes, and to design of new cancer therapies based on targeted delivery of Ru(II) arene complexes bound on pro-apoptotic/anti-proliferating proteins as vehicles.

AB  - Upon release in response to stress, epinephrine (Epi) may interact with labile iron pool in human plasma with potentially important (patho)physiological consequences. We have shown that Epi and Fe3+ build stable 1:1 high-spin bidentate complex at physiological pH, and that Epi does not undergo degradation in the presence of iron. However, the interactions of Epi with the more soluble Fe2+, and the impact of iron on biological activity of Epi are still not known. Herein we showed that Epi and Fe2+ build colorless complex which is stable under anaerobic conditions. In the presence of O2, Epi promoted the oxidation of Fe2+ and the formation of Epi-Fe3+ complex. Cyclic voltammetry showed that mid-point potential of Epi-Fe2+ complex is very low (−582 mV vs. standard hydrogen electrode), which explains catalyzed oxidation of Fe2+. Next, we examined the impact of iron binding on biological performance of Epi using patch clamping in cell culture with constitutive expression of adrenergic receptors. Epi alone evoked an increase of outward currents, whereas Epi in the complex with Fe3+ did not. This implies that the binding of Epi to adrenergic receptors and their activation is prevented by the formation of complex with iron. Pro-oxidative activity of Epi-Fe2+ complex may represent a link between chronic stress and cardiovascular problems. On the other hand, labile iron could serve as a modulator of biological activity of ligands. Such interactions may be important in human pathologies that are related to iron overload or deficiency.
