In this contribution, four new compounds synthesized from 4-hydroxycoumarin and tyramine/octopamine/norepinephrine/3-methoxytyramine are characterized spectroscopically (IR NMR), chromatographically (UHPLC-DAD), structurally at the B3LYP/6-311++G*(d,p) level of theory. The crystal structure 4-hydroxycoumarin-octopamine derivative was solved used as a starting geometry for structural optimization. Along with previously obtained 4-hydroxycoumarin-dopamine derivative, intramolecular...
Iridoids, a class of atypical monoterpenes, exhibit exceptional diversity within the Nepeta genus (subfam. Nepetoidae, fam. Lamiaceae).The majority these plants produce iridoids unique stereochemistry, with nepetalactones (NLs) predominating; however, few species lack compounds. By comparatively analyzing metabolomics, transcriptomics, gene co-expression, and phylogenetic data iridoid-producing N. rtanjensis Diklić & Milojević iridoid-lacking nervosa Royle Bentham, we presumed that...
Two Balkan Peninsula endemics, Nepeta rtanjensis and N. argolica subsp. argolica, both characterized by specialized metabolite profiles predominated iridoids phenolics, are differentiated according to the stereochemistry of major iridoid aglycone nepetalactone (NL). For first time, present study provides a comparative analysis antimicrobial immunomodulating activities two species their isolated from natural sources—cis,trans-NL, trans,cis-NL, 1,5,9-epideoxyloganic acid (1,5,9-eDLA), as well...
Leaching of copper smelting slag in chloride media was studied. The lixiviants used were aqueous solutions hydrochloric acid (0.5-2.0 M HCl) as well hydrogen peroxide and (0.5-3.0 H2O2, 1.0 HCl). maximum final extraction from the 73% attained with 3 at room temperature after 120 minutes reaction. At same time, 55% iron also dissolved. increased during first 60 reaction essentially ceased thereafter. Because a rapid catalytic decomposition peroxide, it should be added contiuously to leach...
Introduction. We tested whether the microclimate under grey hail protection nets (HPN) had an influence on phenology, vegetative and reproductive potential, fruit quality traits of ’Duke’ highbush blueberry (Vaccinium corymbosum L.) in two consecutive years (2013, 2014). Materials methods. Light intensity, air temperature relative humidity were evaluated together with biological properties (flowering ripening time, bush height volume, number flowers fruits per bush, set percentage, yield...
Abstract Algal biomass is a viable source of chemicals and metabolites for various energy, nutritional, medicinal agricultural uses. While stresses have commonly been used to induce metabolite accumulation in microalgae attempts enhance high-value product yields, this often very detrimental growth. Therefore, understanding how modify metabolism without deleterious consequences highly beneficial. We demonstrate that low-doses (1–5 Gy) ionizing radiation the X-ray range induces non-toxic,...
Biliverdin (BV), a product of heme catabolism, is known to interact with transition metals, but the details such interactions under physiological conditions are scarce. Herein, we examined coordinate/redox BV Cu2+ in phosphate buffer at pH 7.4, using spectrophotometry, HESI-MS, Raman spectroscopy, 1H NMR, EPR, fluorimetry, and electrochemical methods. formed stable coordination complex copper 1 : stoichiometry. The structure was more planar energetically complex. showed strong paramagnetic...
Microalgae have evolved mechanisms to respond changes in copper ion availability, which are very important for normal cellular function, tolerate metal pollution of aquatic ecosystems, and modulation bioavailability toxicity other organisms. Knowledge application these will benefit the use microalgae wastewater processing biomass production, compounds suppression harmful algal blooms. Here, using electron microscopy, synchrotron radiation-based Fourier transform infrared spectroscopy,...
The effects of a fructose-rich diet and chronic stress on copper metabolism in the kidneys are still understudied. We investigated whether fructose and/or unpredictable modulate way that affects redox homeostasis, thus contributing to progression metabolic disturbances kidney. determined protein level transporters, chaperones, cuproenzymes including cytochrome c oxidase, as well antioxidant enzymes function male Wistar rats subjected 20% liquid supplementation stress. Liquid increased...
Abstract Metabolism of metals in microalgae and adaptation to metal excess are significant environmental importance. We report a three-step mechanism that the green microalga Chlorella sorokiniana activates during acquisition manganese (Mn), which is both an essential trace pollutant waters. In early stage, Mn2+ was mainly bound membrane phospholipids phosphates released mucilage. The outer cell wall reorganized lipids were accumulated, with relative increase lipid saturation. Intracellular...
In this study, the concentrations of metals and trace elements (As, Cd, Co, Cr, Cu, Hg, Ni, Pb Zn) were determined in muscle tissue adult roach white bream at two different sites Belgrade section Danube. Twenty-six fatty acids, consisting nine saturated FA (SFAs), seven monosaturated (MUFAs) ten polysaturated (PUFAs), identified. The analysis concentration showed species-specific differences their bioaccumulation. Four all analyzed Ni Pb) correlated significantly with changes profiles fish...
<p>The diverse uses of microalgae in ecological remediation, wastewater treatment, pharmaceutics, or food and biofuel production, have long kept these single-celled organisms the spotlight. The focus this study was on <i>Chlamydomonas acidophila</i> strain PM01, which thrives acidic aquatic systems is resistant to presence heavy metals its environment. redox metabolism microalga assessed by ability reduce EPR-active spin probe TEMPO...
In this study, the concentrations of metals (As, Cd, Co, Cr, Cu, Hg, Ni, Pb, and Zn) were deter-mined in two freshwater fish species. The same also used to determine content fatty acids (FA), including saturated (SFA), monounsaturated (MUFA), polyunsaturated (PUFA). We investigated species-specific relationship between bioaccumulation FA.
