Antioxidant activity -- Bacterial enzymes -- Fullerenol -- Hormesis -- Luminous marine bacteria -- Ultralow concentrations
Аннотация: Fullerenols are nanosized water-soluble polyhydroxylated derivatives of fullerenes, specific allotropic form of carbon, bioactive compounds and perspective pharmaceutical agents. Antioxidant activity of fullerenols was studied in model solutions of organic and inorganic toxicants of oxidative type – 1,4-benzoquinone and potassium ferricyanide. Two fullerenol preparations were tested: С60О2–4(ОН)20–24 and mixture of two types of fullerenols С60О2–4(ОН)20–24+С70О2–4(ОН)20–24. Bacteria-based and enzyme-based bioluminescent assays were used to evaluate a decrease in cellular and biochemical toxicities, respectively. Additionally, the enzyme-based assay was used for the direct monitoring of efficiency of the oxidative enzymatic processes. The bacteria-based and enzyme-based assays showed similar peculiarities of the detoxification processes: (1) ultralow concentrations of fullerenols were active (ca 10–17–10−4 and 10–17–10−5 g/L, respectively), (2) no monotonic dependence of detoxification efficiency on fullerenol concentrations was observed, and (3) detoxification of organic oxidizer solutions was more effective than that of the inorganic oxidizer. The antioxidant effect of highly diluted fullerenol solutions on bacterial cells was attributed to hormesis phenomenon; the detoxification was concerned with stimulation of adaptive cellular response under low-dose exposures. Sequence analysis of 16S ribosomal RNA was carried out; it did not reveal mutations in bacterial DNA. The suggestion was made that hydrophobic membrane-dependent processes are involved to the detoxifying mechanism. Catalytic activity of fullerenol (10−8 g/L) in NADH-dependent enzymatic reactions was demonstrated and supposed to contribute to adaptive bacterial response.

Biological activity of carbonic nano-structures—comparison via enzymatic bioassay / A. S. Sachkova [et al.] // J. Soils Sed. - 2019. - Vol. 19, Is. 6. - P. 2689–2696, DOI 10.1007/s11368-018-2134-9. - Cited References: 38. - This work was supported by the state budget allocated to the fundamental research at the Russian Academy of Sciences, project 0356-2017-0017; PRAN-32, Program: “Nanostructures: physics, chemistry, biology, technological basis.” Study of ROS involvement to antioxidant activity of humic substances was supported by the Russian Science Foundation, grant 16-14-10115. . - ISSN 1439-0108
Кл.слова (ненормированные):
Antioxidant activity -- Bioactive compounds -- Fullerenol -- Humic substances -- Toxicity -- Reactive oxygen species
Аннотация: Purpose: The aim of the work is to compare the biological activity of carbonic nano-structures of natural and artificial origination, namely, humic substances (HS) and fullerenols. Materials and methods: The representative of the fullerenol group, С60Оy(OH)x where у + x = 20–22, was chosen. Enzyme-based luminescent bioassay was applied to evaluate toxicity and antioxidant properties of HS and fullerenol (F); chemiluminescent luminol method was used to study a content of reactive oxygen species (ROS) in the solutions. Toxicity of the bioactive compounds was evaluated using effective concentrations ЕС50; detoxification coefficients DOxT were applied to study and compare antioxidant activity of the compounds. Antioxidant activity and ranges of active concentrations of the bioactive compounds were determined in model solutions of organic and inorganic oxidizers—1,4-benzoquinone and potassium ferricianide. Results and discussion: Values of ЕС50 revealed higher toxicity of HS than F (0.005 and 0.108 g L−1, respectively); detoxifying concentrations of F were found to be lower. Antioxidant ability of HS was demonstrated to be time-dependent; the 50-min preliminary incubation in oxidizer solutions was suggested as optimal for the detoxification procedure. On the contrary, F’ antioxidant effect demonstrated independency on time. Antioxidant effect of HS did not depend on amphiphilic characteristics of the media (values of DOxT were 1.3 in the solutions of organic and inorganic oxidizers), while this of F was found to depend: it was maximal (DOxT = 2.0) in solutions of organic oxidizer, 1,4-benzoquinone. Conclusions: Both HS and F demonstrated toxicity and low-concentration antioxidant ability; however, quantitative characteristics of their effects were different. The differences were explained with HS polyfunctionality, higher ability to decrease ROS content, non-rigidity, and diffusion restrictions in their solutions. Antioxidant effect of the bioactive compounds was presumably attributed to catalytic redox activity of their π-fragments. The paper demonstrates a high potential of luminescent enzymatic bioassay to study biological activity of nano-structures of natural and artificial origination.

Antioxidant Activity and Toxicity of Fullerenols via Bioluminescence Signaling: Role of Oxygen Substituents / E. S. Kovel [et al.] // Int. J. Mol.

bioactive compound -- fullerenol -- antioxidant activity -- toxicity -- reactive oxygen species -- bioluminescence bioassay
Аннотация: Fullerenols are nanosized water-soluble polyhydroxylated derivatives of fullerenes, a specific allotropic form of carbon, bioactive compounds, and perspective basis for drug development. Our paper analyzes the antioxidant activity and toxicity of a series of fullerenols with different number of oxygen substituents. Two groups of fullerenols were under investigation: (1) C60Oy(OH)(x), C60,70Oy(OH)(x), where x+y = 24-28 and (2) C60,70Oy(OH)(x), Fe0,5C60Oy(OH)(x), Gd@C82Oy(OH)(x), where x+y = 40-42. Bioluminescent cellular and enzymatic assays (luminous marine bacteria and their enzymatic reactions, respectively) were applied to monitor toxicity in the model fullerenol solutions and bioluminescence was applied as a signaling physiological parameter. The inhibiting concentrations of the fullerenols were determined, revealing the fullerenols' toxic effects. Antioxidant fullerenol' ability was studied in solutions of model oxidizer, 1,4-benzoquinone, and detoxification coefficients of general and oxidative types (D-GT and D-OxT) were calculated. All fullerenols produced toxic effect at high concentrations (>0.01 g L-1), while their antioxidant activity was demonstrated at low and ultralow concentrations (<0.001 g L-1). Quantitative toxic and antioxidant characteristics of the fullerenols (effective concentrations, concentration ranges, D-GT, and D-OxT) were found to depend on the number of oxygen substituents. Lower toxicity and higher antioxidant activity were determined in solutions of fullerenols with fewer oxygen substituents (x+y ⋍ 24-28). The differences in fullerenol properties were attributed to their catalytic activity due to reversible electron acceptance, radical trapping, and balance of reactive oxygen species in aqueous solutions. The results provide pharmaceutical sciences with a basis for selection of carbon nanoparticles with appropriate toxic and antioxidant characteristics. Based on the results, we recommend, to reduce the toxicity of prospective endohedral gadolinium-fullerenol preparations Gd@C82Oy(OH)(x), decreasing the number of oxygen groups to x+y ⋍ 24-28. The potential of bioluminescence methods to compare toxic and antioxidant characteristics of carbon nanostructures were demonstrated.

Endohedral metallofullerene -- Fullerenol -- Impedance -- Dielectric permittivity -- Ionic and proton conductivity -- Dielectric hysteresis -- Polarizability
Аннотация: The paper presents the results of experimental measurements of constitutive and electrophysical properties in hydroxylated endohedral metallofullerene with gadolinium sample. We extracted endohedral metallofullerene from carbon condensate, synthesized in high-frequency arc discharge plasma. Later hydroxyl groups were added. Via methods of infrared and x-ray photoelectronic spectroscopy, it was established that the molecules of hydroxylated endohedral metallofullerene have the Gd@C82Ox(OH)y, x + y=(40–42) composition. The method of measuring the electrical impedance in the frequency range from 100 Hz to 100 MHz shows that the resulting hydroxylated fullerene is an ion conductor. The measured frequency dependences of the dielectric permittivity and conductivity of hydroxylated fullerene are explained based on the assumption of an inhomogeneous distribution of electric charges in the material volume. Dielectric-hysteresis loops in the frequency range of 25 Hz–1 MHz and temperature range of 80–300 K, and volt-ampere characteristics were measured. The obtained results imply the appearance of residual polarization induced by the electric field in hydroxylated fullerene. However, the constant dipole moment is absent. © 2019

Аннотация: Fullerene is a nanosized carbon structure with potential drug delivery applications. We studied the bioeffects of a water-soluble fullerene derivative, fullerenol, with 10-12 oxygen groups (F10-12); its structure was characterized by IR and XPS spectroscopy. A bioluminescent enzyme system was used to study toxic and antioxidant effects of F10-12 at the enzymatic level. Antioxidant characteristics of F10-12 were revealed in model solutions of organic and inorganic oxidizers. Low-concentration activation of bioluminescence was validated statistically in oxidizer solutions. Toxic and antioxidant characteristics of F10-12 were compared to those of homologous fullerenols with a higher number of oxygen groups:F24-28 and F40-42. No simple dependency was found between the toxic/antioxidant characteristics and the number of oxygen groups on the fullerene’s carbon cage. Lower toxicity and higher antioxidant activity of F24-28 were identified and presumptively attributed to its higher solubility. An active role of reactive oxygen species (ROS) in the bioeffects of F10-12 was demonstrated. Correlations between toxic/antioxidant characteristics of F10-12 and ROS content were evaluated. Toxic and antioxidant effects were related to the decrease in ROS content in the enzyme solutions. Our results reveal a complexity of ROS effects in the enzymatic assay system.

endohedral fullerenol -- gadolinium -- toxicity -- oxidative stress -- antioxidant activity -- reactive oxygen species -- bioluminescence bioassay -- hormesis
Аннотация: The Gd-containing metallofullerene derivatives are perspective magnetic resonance imaging contrast agents. We studied the bioeffects of a water-soluble fullerene derivative, gadolinium-endohedral fullerenol, with 40–42 oxygen groups (Gd@Fln). Bioluminescent cellular and enzymatic assays were applied to monitor toxicity and antioxidant activity of Gd@Fln in model solutions; bioluminescence was applied as a signaling physiological parameter. The Gd@Fln inhibited bioluminescence at high concentrations (>2·10−1 gL−1), revealing lower toxicity as compared to the previously studied fullerenols. Efficient activation of bioluminescence (up to almost 100%) and consumption of reactive oxygen species (ROS) in bacterial suspension were observed under low-concentration exposure to Gd@Fln (10−3–2·10−1 gL−1). Antioxidant capability of Gd@Fln was studied under conditions of model oxidative stress (i.e., solutions of model organic and inorganic oxidizers); antioxidant coefficients of Gd@Fln were determined at different concentrations and times of exposure. Contents of ROS were evaluated and correlations with toxicity/antioxidant coefficients were determined. The bioeffects of Gd@Fln were explained by hydrophobic interactions, electron affinity, and disturbing of ROS balance in the bioluminescence systems. The results contribute to understanding the molecular mechanism of “hormetic” cellular responses. Advantages of the bioluminescence assays to compare bioeffects of fullerenols based on their structural characteristics were demonstrated.

C82 -- Gd endohedral complexes -- biomedical applications -- fullerenols -- DFTB3 electronic structure calculations -- IR spectra
Аннотация: Gd@C82OxHy endohedral complexes for advanced biomedical applications (computer tomography, cancer treatment, etc.) were synthesized using high-frequency arc plasma discharge through a mixture of graphite and Gd2O3 oxide. The Gd@C82 endohedral complex was isolated by high-efficiency liquid chromatography and consequently oxidized with the formation of a family of Gd endohedral fullerenols with gross formula Gd@C82O8(OH)20. Fourier-transformed infrared (FTIR) spectroscopy was used to study the structure and spectroscopic properties of the complexes in combination with the DFTB3 electronic structure calculations and infrared spectra simulations. It was shown that the main IR spectral features are formed by a fullerenole C82 cage that allows one to consider the force constants at the DFTB3 level of theory without consideration of gadolinium endohedral ions inside the carbon cage. Based on the comparison of experimental FTIR and theoretical DFTB3 IR spectra, it was found that oxidation of the C82 cage causes the formation of Gd@C82O28H20, with a breakdown of the integrity of the parent C82 cage with the formation of pores between neighboring carbonyl and carboxyl groups. The Gd@C82O6(OOH)2(OH)18 endohedral complex with epoxy, carbonyl and carboxyl groups was considered the most reliable fullerenole structural model.

Аннотация: Цель исследования - изучить влияние фуллеренола C60(OH)20-24 на процесс спиртового брожения в производстве спирта. Задачи: провести процесс спиртового брожения с использованием фуллеренола; исследовать органолептические показатели, содержание углеводов и спирта в браге; рассмотреть возможность влияния полигироксилированного фуллерена на массу сухого остатка дрожжей после термостатирования и осветления браги. Объект исследования - модельные образцы браги с добавлением в малых дозах полигидроксилированного фуллерена C60(OH)20-24. Контрольный образец производили по традиционной рецептуре, в I опытный образец дополнительно к основной рецептуре добавляли фуллеронол 0,01 г (0,1 % от массы гидромодуля); во II опытный образец - 0,03 г (0,3 % от массы гидромодуля). Все исследования проводили в трехкратном повторении. Во всех образцах исследовали органолептические, физико-химические показатели и массу сухого остатка дрожжей в конце брожения. В результате исследования воспроизведен технологический процесс производства зрелой браги с использованием фуллеренола. Установлено, что использование фуллеренола в малых дозах 0,3 % от массы гидромодуля (II опытный образец) при производстве браги в технологии спирта позволяет улучшить органолептические показатели за счет запаха и вкуса на 1 балл, снизить показатель активной кислотности на 0,11 ед. и содержание углеводов в браге на 1,2 %, повысить содержание спирта на 0,8 %, что свидетельствует об улучшении бродильной активности дрожжей. Масса сухого остатка дрожжей после брожения во II опытном образце по сравнению с контрольным увеличивается на 14 %, что может свидетельствовать о фуллереноле как биостимуляторе, который позволяет интенсифицировать процесс спиртового брожения.
The purpose of research is to study the effect of C60(OH)20-24 fullerenol on the process of alcoholic fermentation in the production of alcohol. Tasks: to carry out the process of alcoholic fermentation using fullerenol; to investigate organoleptic indicators, the content of carbohydrates and alcohol in mash; to consider the possibility of the influence of polyhydroxylated fullerene on the mass of dry yeast residue after thermostating and clarification of the mash. The object of the study is model samples of mash with the addition of polyhydroxylated fullerene C60(OH)20-24 in small doses. The control sample was produced according to the traditional recipe, in the first prototype, in addition to the main recipe, fulleronol 0.01 g (0.1 % of the weight of the hydromodule) was added; in the II prototype - 0.03 g (0.3 % of the mass of the hydromodule). All studies were carried out in triplicate. In all samples, the organoleptic, physico-chemical parameters and the mass of dry yeast residue at the end of fermentation were studied. As a result of research, the technological process for the production of mature mash using fullerenol was reproduced. It has been established that the use of fullerenol in small doses of 0.3 % of the weight of the hydromodule (II prototype) in the production of home brew in the technology of alcohol makes it possible to improve organoleptic characteristics due to smell and taste by 1 point, to reduce the active acidity index by 0.11 units and the content of carbohydrates in the mash by 1.2 %, increase the alcohol content by 0.8 %, which indicates an improvement in the fermentation activity of yeast. The weight of the dry residue of yeast after fermentation in the second prototype increases by 14 % compared to the control, which may indicate fullerenol as a biostimulant that allows intensifying the process of alcoholic fermentation.
