The translational mobility is characterised quantitatively by a self-diffusion coefficient. The aim of the study was to summarise the main trends in application of DOSY for the analysis of natural and modified natural polysaccharides used in pharmaceuticals and pharmaceutical biotechnology. The review shows that this method is an effective instrument for monitoring fractionation during isolation of polysaccharides from a natural mixture, for estimating their average molecular weight and molecular weight distribution, and for studying the formation of supramolecular systems based on polysaccharides. The paper describes main issues of the precise measurement of polysaccharide macromolecules self-diffusion coefficients and provides the correction factors to compensate for errors caused by fluctuations in temperature and viscosity of solutions. The observed scatter of self-diffusion coefficients of narrowly dispersed polymer macromolecules nuclei is explained using the polyphase concept. The paper illustrates ways of describing translational mobility of a polyphase polymer macromolecule as a whole. The authors summarise values of the gradient pulse sequence parameters used in quantitative measurements of self-diffusion coefficients of linear, low-branched, and branched polysaccharides. ","PeriodicalId":22286,"journal":{"name":"The Bulletin of the Scientific Centre for Expert Evaluation of Medicinal Products","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80471841","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}

One of the species encountered in Russia, the large-flowered corydalis (Corydalis bracteata (Steph. ex Willd.) Pers.), is widespread in Western and Eastern Siberia, but none the less its chemical composition has not been properly studied yet.The aim of the study was to perform phytochemical analysis of Corydalis bracteata herb through isolation of the main secondary metabolites and elucidation of their structure, using modern chromatographic methods of analysis and NMR spectroscopy.Materials and methods: the analysis was performed for dried aerial parts of C. bracteata. The isolation of individual compounds was performed using open-column chromatography and glass columns packed with sorbents with different selectivity characteristics— Dianion® HP-20 (Supelco) and Sephadex® LH-20 (GE Healthcare)—as well as preparative-scale chromatography with a Kromasil® C18 column and detection at 235 nm. Water and acetonitrile mixed in the ratios 5:95–50:50 v/v with the addition of 0.1% trifluoroacetic acid were used as the eluents. The analysis of fractions before pooling was performed by high-performance thin-layer chromatography with Silica gel 60 F254 plates (Merck). The analysis of the individual compound solutions was performed by HPLC using a Prominence LC-20 (Shimadzu) instrument, a SUPELCOSIL™ LC-18 column, and detection at 235 nm. The structures of the isolated individual compounds were elucidated by one- and two-dimensional NMR spectroscopy using a Bruker Avance III 400 MHz NMR spectrometer.Results: four individual compounds from the С. bracteata aerial parts were isolated and analysed: an isoquinoline alkaloid— coptisine (1) and three flavonoids—rutin (2), quercetin-3-O-β-D-glucopyranoside (3), and kaempferol-3-O-β-D-glucopyranoside (4).Conclusions: as a result of the phytochemical analysis of the С. bracteata aerial parts, compounds of both alkaloid and flavonoid nature were isolated for the first time, and their structures were elucidated using NMR spectroscopy. С. bracteata should be considered as a promising potential source of biologically active substances.","PeriodicalId":22286,"journal":{"name":"The Bulletin of the Scientific Centre for Expert Evaluation of Medicinal Products","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87052260","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}

Their characteristic feature is that they can be consumed directly, without prior extraction of the starting material. All elemental toxicants contained in pumpkin seeds are transferred in full to the native product. Therefore, it is important to study specific aspects of elemental toxicant accumulation by pumpkin seeds.The aim of the study was to determine the content of heavy metals, As, and Al in pumpkin seed herbal substance and native products, and to assess the degree of accumulation of these elements, depending on the vegetation area.Materials and methods: the study evaluated pumpkin seed native products by Russian manufacturers as well as pumpkin seeds harvested in areas with different anthropogenic load. The sample preparation was performed by microwave digestion, and the determination of the elemental toxicants was perfomed by inductively coupled plasma mass spectrometry.Results: the pumpkin seeds were shown to contain essential, probably essential, potentially toxic, and toxic elements. The authors performed comparative analysis of the elemental composition of pumpkin seeds as well as seeds, grains, and beans of various oil-bearing, grain, and leguminous crops.Conclusions: the content of the specified elemental toxicants (As, Cd, Hg, Pb) in the tested samples of pumpkin seed herbal substance and herbal medicinal products did not exceed the limits established by the Russian Pharmacopoeia. The unspecified toxic elements were either absent in pumpkin seeds (Tl) or found in trace amounts (Al). The content of a number of essential elements (Zn, Fe, Mn, Cu, Mo, Cr) in pumpkin seeds was higher than in the seeds of many oil-bearing crops. The vegetation area had no significant influence on the content of the tested elements in the pumpkin seeds. Pumpkin seeds are capable of accumulating abnormally high amounts of Cd, Co, and Ni in areas with high environmental pollution.","PeriodicalId":22286,"journal":{"name":"The Bulletin of the Scientific Centre for Expert Evaluation of Medicinal Products","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84078265","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 aim of the study was to compare the extent of medicine quality characteristics assessed by NMR in the Russian and foreign pharmacopoeias. The review summarises the experience of various national and world pharmacopoeias in using the NMR method for quality control of medicines and certification of pharmacopoeial reference materials. The comparative analysis covered the following quality parameters: active ingredient identification, determination of the composition of non-stoichiometric compounds, determination of the average polymer chain length in polymers and block copolymers, determination of the absolute content of the active ingredient, identification and quantification of impurities, polymorphism, and crystallinity. It was shown that the United States and Japanese Pharmacopoeias are leading the way in introducing the NMR method into pharmacopoeial analysis. There have been some positive trends in the introduction of the NMR method in the State Pharmacopoeia of the Russian Federation as well. It was concluded that changes are needed in the general chapters “Nuclear Magnetic Resonance Spectroscopy” and “Reference Standards” of the State Pharmacopoeia of the Russian Federation, 14th ed. in order to harmonise the texts with those of the Eurasian Pharmacopoeia and the European Pharmacopoeia and to allow for the possibility of direct identification of a substance by complex analysis of NMR spectral data, without comparing the test sample and the reference standard spectra. The NMR method should be included in the list of absolute methods used for determination of purity of primary chemical reference substances during certification.","PeriodicalId":22286,"journal":{"name":"The Bulletin of the Scientific Centre for Expert Evaluation of Medicinal Products","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79682135","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}

Test procedures submitted by manufacturers often need to be clarified, and validation protocols often lack data.The aim of the study was to provide recommendations to HS and HMP manufacturers on the choice of test methods, materials, reagents, methods of organic matrix mineralisation, and main validation parameters, as well as recommendations on validation of the procedure for elemental toxicants determination, and preparation of the “Heavy metals and arsenic” part of the regulatory submission.Materials and methods: the study included analysis and systematisation of scientific literature, requirements of the Russian and foreign pharmacopoeias, guidelines, manuals on instrumental methods of analysis, and first-hand experience in elemental analysis of various types of HSs and HMPs.Results: the authors formulated recommendations on the choice of sample mineralisation conditions for quantification of elemental impurities in biological products, and substantiated requirements for the reagents, materials, and equipment. The paper compares different methods of elemental analysis. It was demonstrated that the main mistakes made by manufacturers stem from disregard to the organic matrix effect on the measurement results and lack of agreement between the impurity concentration being determined and the range of the calibration curve used. The paper gives acceptance criteria for validation parameters of test procedures for heavy metals and arsenic determination in HSs and HMPs.Conclusions: it is not correct to use reference standards containing heavy metals as inorganic salts not bound to organic compounds, for HS and HMP analysis. The criteria given in the European Pharmacopoeia and the United State Pharmacopoeia can be used for a number of validation parameters, when they are not included in the Russian Pharmacopoeia.","PeriodicalId":22286,"journal":{"name":"The Bulletin of the Scientific Centre for Expert Evaluation of Medicinal Products","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86030405","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}

This requires careful monitoring of the use of potential genotoxicants including medicinal products (MPs), which are a group of compounds intentionally and routinely used by humans. Genotoxicity assesment is highly essential in preclinical drug safety studies. The aim of the study was to analyse the current situation and reveal possible ways of addressing methodological and regulatory issues in genotoxicology to enable proper conduction of drug safety preclinical studies. The article summarises basic concepts of the modern genetic toxicology development and highlights the history of research aimed at identifying mutagenic, clastogenic, and aneugenic effects. The authors analyse regulatory aspects of genotoxicological studies of MPs and consider issues of improving the strategy for genotoxicity testing. The paper gives information about the genotoxicity tests approved for MPs, recommendations for interchangeability of tests in relation to particular study characteristics. The authors carried out a comparative analysis of the tests’ pros and cons with an emphasis that the study of each MP is a separate scientific task. They discuss interpretation of results and prediction of MP carcinogenic potential in genotoxicological studies. Recommendations are given for the optimisation of the MP genotoxicity assessment strategy, considering its partial integration into general toxicity studies. The article stresses the urgent need to develop registration methods for genotoxic events in germ cells, assesses the prospects of new tests, and reviews new trends in drug genotoxicology fundamental research.","PeriodicalId":22286,"journal":{"name":"The Bulletin of the Scientific Centre for Expert Evaluation of Medicinal Products","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87691520","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}
