Not only the search for new plant antioxidants, but also the study of the factors affecting their accumulation in plants, are relevant.The aim is to study the interrelation between the activity of mitochondrial enzymes and the antioxidant activity of the secondary polyphenolic nature metabolites in hemiparasite Viscum Album L. leaves.Materials and methods. The sampling material was Viscum album L. leaves, collected in winter from a host tree, Malus domestica Borkh. The extraction of biologically active substances was carried out with ethyl alcohol of various concentrations (90%, 70% and 50%), or purified water. The amount of total antioxidants was estimated by the amperometric method. The amount of total phenols was evaluated in the reaction with the Folin-Ciocalteu reagent. The concentration of total flavonoids was estimated by the change in the optical density of the rutin with aluminum (III) chloride complex. The antioxidant properties of the analyzed extracts were determined in vitro in the induced lipid peroxidation test. The activity of aconitase was assessed by a conjugated aconitase-isocitrate dehydrogenase reaction, citrate synthase – by changing the color intensity of the Ellman reagent solution, succinate dehydrogenase were determined in the reaction of succinate-dependent oxidation of 2,6-dichlorophenolindophenol.Results. The carried out study showed that the maximum amount of total phenols (2.39±0.05%) is observed in a 50% ethanol extract from Viscum album L. leaves, with the content of total flavonoids equal to 1.83±0.04%, and the antioxidants equal to 0.503±0.007 mg/g (a quercetin equivalent) and 0.322±0.006 mg/g (a gallic acid equivalent). A 50% ethanol extract suppressed lipid peroxidation in the model mixture with IC50=106.3±1.09 µg/ml. In Viscum album L. leaves, a high activity of aconitase which strongly correlated (r=0.88416) with changes in the concentration of flavonoids, has been notified.Conclusion. The optimal extractant for obtaining extracts with a high antioxidant activity is 50% ethyl alcohol.

However, to date, the implementation of TDM is associated with various difficulties, for the solution of which more convenient and less invasive methods for collecting biological material are being developed.The aim of the study was to develop protocols for the collection and storage of “dried blood spot” (DBS) samples, as well as protocols for the validation methods for the quantitative determination of drugs in whole blood, using this technology for subsequent therapeutic drug monitoring.Materials and methods. To analyze a “dried blood spot” method in detail and to identify the characteristic features of taking and storing biosamples, a collection and analysis of scientific literature over the past 10 years has been conducted. The search for literature materials has been carried out from open and accessible sources located in the scientific libraries of institutions, in electronic databases and search engines: Elibrary, PubMed, Scopus, Cyberleninka, Medline, ScienceDirect, Web of Science, Google Scholar. Primary protocols for taking, storing and analyzing samples of the “dried blood drop” have been prepared. To obtain the adequate quality samples, the developed protocols have been tested and optimized at the stages of selection and storage. By high-performance liquid chromatography with mass spectrometric detection (HPLC-MS/MS), using a “dried blood drop” as a sample preparation, drug validation protocols have been optimized to ensure that acceptable validation characteristics were achieved, and subsequent Therapeutic Drug Monitoring was performed.Results. The features of the collection, storage and analysis of the “dried blood spot” samples have been revealed. Such characteristics as a spot volume effect, a hematocrit effect, a droplet uniformity, which can affect the results of a quantitative HPLC-MS/MS analysis, have been determined. For a successful use of the new methods, appropriate protocols for taking samples of “dried blood spot” from the finger of adult patients and from the heel of newborns, as well as protocols for validating methods for the quantitative determination of drugs from these samples, have been developed.Conclusion. The application of the “dried blood spot” method using newly developed protocols for taking, storing and analyzing biological samples, relieves the existing constraints in conducting TDM, and can later become a promising method for conducting preclinical and clinical studies.","PeriodicalId":20031,"journal":{"name":"Pharmacology & Pharmacy","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84287031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The review presents the analysis of 389 titles of scientific pharmaceutical publications for the periods of 1995–1998 and 2010–2019. The selection of publications was carried out by the random sampling based on the phrases: «drug provision», «medical care», «provision of medicines», «pharmaceutical care», «medicinal services», «drug supply» and their English-language counterparts in Russian and foreign electronic information sources. A methodological base of the study was a cluster analysis of the subject area concept of “drug supply” according to the methodology proposed by E.A. Korzhavykh and I.V. Voronovich. In this study, a cluster was interpreted as a set of publications in which a certain pair of terms was simultaneously cited with a preset frequency of co-citation.Results. When analyzing the publications, two clusters of the “drug supply” concept were formed for the time periods indicated above. The comparison of the clusters showed an increase in the activity of the scientific research to expand the structure and content of the subject area of the “drug supply” concept. For the modern cluster, 124 co – cited pairs of lexical units were selected. They were grouped into 9 hierarchy levels according to the strength of relationship between an interval of 10 units and mentioning frequencies of the “drug supply” term. At the final stage, a graphical model of the “drug supply” concept cluster was formed. It was established that the lexical units included from the first to the fifth level, are the cluster nucleus of the “drug supply” concept as the most stable part of the lexical array, which it is advisable to rely on when developing a definition for the concept under study.Conclusion. Thus, the subject field of the “drug supply” concept is characterized by the scientific research, reflecting the socio-economic significance of the objects under study in the field of pharmaceutical activities, and its content is characterized by a high level of pharmaceutical knowledge which describes the most stable elements that make it possible to formulate an adequate definition of the “drug supply” definition.","PeriodicalId":20031,"journal":{"name":"Pharmacology & Pharmacy","volume":"141 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80079985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the help of mathematical modeling methods, a pharmacoeconomic “cost-effectiveness” analysis; a “budget impact” analysis; a sensitivity analysis to the changes in the initial parameters of the model, were carried out.Results. The analysis of literature sources made it possible to conclude that the combination of ATZ+VM+COB compared with the combination of NIVO+IPI (15.1 and 11.2 months, respectively) has a greater clinical efficacy in terms of a progression-free survival (PFS) in patients with metastatic melanoma. When choosing the ATZ+VM+COB combination, the total cost of treatment for one adult patient with metastatic melanoma per course was lower, compared to the NIVO+IPI combination (RUB 8 326 864.89 vs RUB 7 172 751.68); the difference amounted to 1 154 113.21 rubles. When calculating the “cost-effectiveness” ratio for a year of a progression-free survival, the advantage of the ATZ + VM + COB combination in comparison with the NIVO + IPI combination, remained (5 700 200.01 rubles vs 8 942 400.10 rubles); the difference amounted to 3 242 200.09 rubles.

In general, there is a number of ways to obtain this substance, although it is not produced in Russia yet.The aim of the study was to select optimal process conditions to increase the efficiency of protein transformation with the isolation of a fat fraction containing fat-soluble vitamin D.Materials and methods. Various types of fish and the vitamins contained in them are described as the main research models. Variants of technological solutions have been considered: the possibility of using extraction to obtain the vitamin D substance has been tested. Classical maceration and intensifying maceration have been used; the circulating extraction method and the alkaline hydrolysis method have been applied. The yield of the target product has been determined by HPLC.Results. Methods for obtaining the substance of fat-soluble vitamin D from fish raw materials have been considered in detail. The optimal technological characteristics of the vitamin release by alkaline hydrolysis with a 12.5% decrease in the concentration of the hydrolyzing alkaline component – potassium hydroxide – has been established; that concentration ensured the maximum yield of the fat fraction containing vitamin D.Conclusion. The use of the resulting substance makes it possible to develop domestic standard samples applicable both in the pharmaceutical field and in the field of technical regulation.","PeriodicalId":20031,"journal":{"name":"Pharmacology & Pharmacy","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77036961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chromatograms of the extracts were obtained by thin layer chromatography in the system of chloroform – ethanol – water (26:16:3). The detection of adsorption zones was carried out in daylight, in the UV light at λ=254 nm and λ=365 nm, as well as by treatment with reagents – a 3% alcohol solution of aluminum chloride and a solution of diazobenzosulfonic acid in a 20% sodium carbonate solution. The next step was to determine the minimum inhibitory concentration by the method of double serial dilutions in Mueller-Hinton nutrient broth (Bio-Rad, USA). As test cultures, the strains of the American Type Culture Collection (ATCC) microorganisms were used: Staphylococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853), as well as Candida albicans (a clinical strain). Simultaneously, an experiment to establish a “negative” control was carried out. For the comparative evaluation of the studied samples activity, its activity was compared with the reference preparation with a proven antimicrobial activity – a eucalyptus tincture.Results. For all water-ethanolic extractions and the Nigella sativa L. herb tincture, the adsorption zones characteristic of flavonoids with Rf1 = 0.28, Rf2 = 0.15, Rf3 = 0.11 were revealed, and under the action of an alcoholic solution of aluminum chloride, the fluorescence of the adsorption zones was also enhanced, which indicates the phenolic nature of these compounds.In the course of the study, it was found out that all water-ethanolic extractions from the Nigella sativa L. herbs have the greatest antimicrobial effect against the Pseudomonas aeruginosa strain. When compared with the reference preparation – a eucalyptus tincture, it was notified that the specified tincture of the Nigella sativa L. herbs has an advantage in the antimicrobial activity over the strain of Pseudomonas aeruginosa – the action at the 16-fold dilution vs the 4-fold dilution. The action on the Escherichia coli and Candida albicans strains is comparable for the both tinctures.Conclusion. The obtained results of phytochemical and microbiological analyses will be used as a rationale for the introduction of antimicrobial preparations based on the Nigella sativa herbs in medical and pharmaceutical practice.","PeriodicalId":20031,"journal":{"name":"Pharmacology & Pharmacy","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83114963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
