Abstract
Plant adaptive strategies have been shaped during evolutionary development in the constant interaction with a plethora of environmental factors, including the presence of metals/metalloids in the environment. Among adaptive reactions against either the excess of trace elements or toxic doses of non-essential elements, their complexation with molecular endogenous ligands, including phenolics, has received increasing attention. Currently, the complexation of phenolics with metal(loid)s is a topic of intensive studies in different scientific fields. In spite of the numerous studies on their chelating capacity, the systemic analysis of phenolics as plant ligands has not been performed yet. Such a systematizing can be performed based on the modern approach of metallomics as an integral biometal science, which in turn has been differentiated into subgroups according to the nature of the bioligands. In this regard, the present review summarizes phenolics–metal(loid)s’ interactions using the metallomic approach. Experimental results on the chelating activity of representative compounds from different phenolic subgroups in vitro and in vivo are systematized. General properties of phenolic ligands and specific properties of anthocyanins are revealed. The novel concept of metallophenolomics is proposed, as a ligand-oriented subgroup of metallomics, which is an integrated approach to study phenolics–metal(loid)s’ complexations. The research subjects of metallophenolomics are outlined according to the methodology of metallomic studies, including mission-oriented biometal sciences (environmental sciences, food sciences and nutrition, medicine, cosmetology, coloration technologies, chemical sciences, material sciences, solar cell sciences). Metallophenolomics opens new prospects to unite multidisciplinary investigations of phenolic–metal(loid) interactions.

Abstract
AIM This study was done to investigate the anti-diabetic and anti-oxidative synergism between zinc(II) and ferulic acid through complexation. METHODS Zinc sulphate was complexed with ferulic acid in a 1:2 molar ratio. The complex was characterized using Fourier-transform infrared spectroscopy, proton NMR and high-resolution mass spectroscopy techniques and evaluated for cellular toxicity. In silico, in vitro, cell-based and tissue experimental models were used to test the anti-diabetic and anti-oxidant activities of the complex relative to its precursors. RESULTS A zinc(II)-biferulate.2H2 O complex was formed. The in vitro radical scavenging, anti-lipid peroxidative and α-glucosidase and α-amylase inhibitory activity of the complex was 1.7-2.1 folds more potent than ferulic acid. Zn(II) complexation increased the anti-glycation activity of ferulic acid by 1.5 folds. The complex suppressed lipid peroxidation (IC50 = 48.6 and 331 μM) and GHS depletion (IC50 = 33.9 and 33.5 μM) in both Chang liver cells and isolated rat liver tissue. Its activity was 2.3-3.3 folds more potent than ferulic acid and statistically comparable to ascorbic acid. Zn(II) complexation afforded ferulic acid improved glucose uptake activity in L-6 myotube (EC50 = 11.7 vs. 45.7 μM) and isolated rat muscle tissue (EC50 = 501 and 1510 μM). Complexation increased muscle tissue zinc(II) uptake and hexokinase activity. Docking scores of the complex (-7.24 to -8.25 kcal/mol) and ferulic acid (-5.75 to 6.43 kcal/mol) suggest the complex had stronger interaction with protein targets related to diabetes, which may be attributed to the 2 ferulic acid moieties and Zn(II) in the complex. Moreover, muscle tissue showed increased phospho-Akt/pan-Akt ratio upon treatment with complex. The complex was not hepatotoxic and myotoxic at in vitro cellular level. CONCLUSION Zn(II) complexation may be promising therapeutic approach for improving the glycaemic control and anti-oxidative potential of natural phenolic acids.

Abstract
Zinc and syringic acid have metabolic and antioxidant medicinal potentials. A novel zinc(II)-syringic acid complex with improved anti-hyperglycaemic and antioxidant potential was developed. Zinc(II) was complexed with syringic acid in a 1:2 molar ratio and characterized using FT-IR, 1H NMR and LC-MS. Different experimental models were used to compare the anti-hyperglycaemic and antioxidant properties between the complex and precursors. A Zn(II)-bisyringate.2H2O complex was formed. The in vitro radical scavenging and Fe3+ reducing antioxidant, antiglycation, and α-glucosidase inhibitory activities of the complex were 1.8-5.2 folds stronger than those of the syringic acid precursor and comparable to those of the positive controls. The complex possessed an increased ability to inhibit lipid peroxidation (by 1.6-1.7 folds) and glutathione depletion (2.8-3 folds) relative to syringic acid in Chang liver cells and liver tissues isolated from rats. The complex exhibited a higher glucose uptake effect (EC50 = 20.4 and 386 µM) than its precursors (EC50 = 71.1 and 6460 µM) in L6-myotubes and psoas muscle tissues isolated from rats, respectively, which may be linked to the observed increased cellular zinc uptake potentiated by complexation. Tissue glucose uptake activity was accompanied by increased hexokinase activity, suggesting increased glucose utilization. Moreover, treatment increased tissue phospho-Akt/pan-Akt ratio. The complex had strong molecular docking scores than syringic acid with target proteins linked to diabetes. The presence of two syringic acid moieties and Zn(II) in the complex influenced its potency. The complex was not hepatotoxic and myotoxic in vitro. Zinc-syringic acid complexation may be a novel promising therapeutic approach for diabetes and oxidative complications.

Abstract
Natural supplements are important in diabetes and oxidative stress management. A complexation-mediated antihyperglycemic and antioxidant synergism between zinc(II) and p-coumaric acid was investigated. p-Coumaric acid was complexed with ZnSO4 and characterized by FT-IR, 1 H NMR, and mass spectroscopy. The antioxidant and antihyperglycemic potential of the complex and precursors were evaluated with different experimental models. Molecular docking with target proteins linked to diabetes was performed. A Zn(II)-bicoumarate.2H2 O complex was formed. The in vitro radical scavenging, α-glucosidase inhibitory, antiglycation, and anti-lipid peroxidative activities of the complex were several folds stronger than p-coumaric acid. In Chang liver cells and rat liver tissues, the complex inhibited lipid peroxidation (IC50 = 56.2 and 398 μM) and GSH depletion (IC50 = 33.9 and 38.7 μM), which was significantly stronger (2.3-5.4-folds) than p-coumaric acid and comparable to ascorbic acid. Zn(II) and p-coumaric synergistically modulated (1.7- and 2.8-folds than p-coumaric acid) glucose uptake in L-6 myotubes (EC50 = 10.7 μM) and rat muscle tissue (EC50 = 428 μM), which may be linked to the observed complexation-mediated increase in tissue zinc uptake. Glucose uptake activity was accompanied by increased hexokinase activity, suggesting increased glucose utilization. Docking scores α-glucosidase, GLUT-4, and PKB/Akt showed stronger interaction with the complex (-6.31 to -6.41 kcal/mol) compared to p-coumaric acid (-7.18 to -7.74 kcal/mol), which was influenced by the Zn(II) and bicoumarate moieties of the complex. In vitro, the complex was not hepatotoxic or myotoxic. Zn(II) complexation may be a therapeutic approach for improving the antioxidative and glycemic control potentials of p-coumaric acid. PRACTICAL APPLICATIONS: In functional medicine, natural supplements, plant-derived phenolics, and nutraceuticals are becoming popular in the management of diseases, including diabetes and oxidative stress. This has been largely attributed to their perceived holistic medicinal profile and the absence of notable toxicity concerns. In the past two decades, considerable attention has been drawn toward zinc mineral as a possible therapeutic supplement for diabetes due to its role in insulin secretion and reported insulin mimetic potentials. p-Coumaric acid is a known natural antioxidant with reported diabetes-related pharmacological effects. In this study, we took advantage of these properties and complexed both natural supplements, which resulted in a more potent nutraceutical with improved glycemic control and antioxidant potential. The complexation-mediated synergistic interaction between zinc and p-coumaric acid could be an important therapeutic approach in improving the use of these natural supplements or nutraceuticals in managing diabetes and associated oxidative complications.

Abstract
Optimized chemical structure, Raman and SERS spectra of 3,5-dimethoxy-4-hydroxycinnamic acid (35D4HCA) molecule and its silver (Ag) complex were calculated using time-dependent density functional theory in conjunction with B3LYP functional and LANL2DZ/6-311 + G(d,p) basis sets. Moreover, excitation and HOMO-LUMO energies were computed by the same level of theory. Because of the fact that energy of excitation electronic transition depends on infinite lifetime approximation, Raman activities were calculated under this approximation. Normal Raman spectra and SERS spectra of 35D4HCA and its silver complex were obtained with different excitation laser frequencies such as 532 nm and 785 nm and so interaction between metal surface and 35D4HCA was examined using SERS spectra. Moreover, theoretical and experimental UV-VIS spectra in the water of 35D4HCA and its silver complex were obtained and transitions, wavelengths and energy values of samples were shown. 1H NMR experiment of 35D4HCA and its silver complex were performed and it was determined interaction between Ag atoms and 35D4HCA. In order to determine thermal properties of 35D4HCA and its silver complex, TG and DTA analysis were carried out. HOMO and LUMO energy levels corresponding to these energy values were determined and transitions between these levels were determined.

Abstract
The degradation efficiencies and behaviors of caffeic acid (CaA), p-coumaric acid (pCoA), and ferulic acid (FeA) in aqueous sucrose solutions containing the mixture of these hydroxycinnamic acids (HCAs) were studied by the Fenton oxidation process. Central composite design and multiresponse surface methodology were used to evaluate and optimize the interactive effects of process parameters. Four quadratic polynomial models were developed for the degradation of each individual acid in the mixture and the total HCAs degraded. Sucrose was the most influential parameter that significantly affected the total amount of HCA degraded. Under the conditions studied there was a <0.01% loss of sucrose in all reactions. The optimal values of the process parameters for a 200 mg/L HCA mixture in water (pH 4.73, 25.15 °C) and sucrose solution (13 mass %, pH 5.39, 35.98 °C) were 77% and 57%, respectively. Regression analysis showed goodness of fit between the experimental results and the predicted values. The degradation behavior of CaA differed from those of pCoA and FeA, where further CaA degradation is observed at increasing sucrose and decreasing solution pH. The differences (established using UV/vis and ATR-FTIR spectroscopy) were because, unlike the other acids, CaA formed a complex with Fe(III) or with Fe(III) hydrogen-bonded to sucrose and coprecipitated with lepidocrocite, an iron oxyhydroxide.
