Specifically, a large number of uracil series compounds have antitumor, anti-inflammatory, antiviral, and immunomodulatory effects, which makes relevant the synthesis of new biologically active derivatives of the pyrimidine series. It is known that the mechanism of hepatotoxicity of chemical compounds is largely associated with the activation of lipid peroxidation, therefore, the objects of the study were uracil derivatives containing a proton-donating group in position C5, which significantly increases the antioxidant properties of the compound. Methods: For the synthesis of uracil derivatives, modification of 5-hydroxy- and 5-amino-6-methyluracils, containing pre-protected C5 functional groups, with various alkyl substituents introduced at N1,N3 positions was carried out. The method of preliminary etching of cells with the hepatotoxicant carbon tetrachloride and their treatment with the tested compounds was selected for the study of the hepatoprotective activity. Results and Discussion: The introduction of various alkyl substituents at the N1,N3 positions of 5-hydroxy- and 5-amino-6-methyluracils was shown to increase the solubility of these compounds; the hepatoprotective activity of the synthesized compounds was revealed. Conclusions: New di- and monoalkyl derivatives of 5-hydroxy- and 5-amino-6-methyluracils were obtained, and their hepatoprotective activity was tested in vitro. According to the test results, five of the 20 new compounds synthesized promote cell survival when pretreated with carbon tetrachloride.","PeriodicalId":758,"journal":{"name":"Russian Journal of Bioorganic Chemistry","volume":"51 1","pages":"117 - 127"},"PeriodicalIF":1.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143396675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The molecular profiles of these membrane lipids were determined using high-performance liquid chromatography in combination with high-resolution mass spectrometry. Results and Discussion: It was shown that the profile of PI molecular species is not related to the lifespan of the mussels and the sea urchins, in contrast to the profiles of PC, PE, and PS molecular species. Sea urchins M. nudus and mussel C. grayanus with longer lifespans were characterized by an increased content of PC, PE, and PS with odd-numbered alkyl/acyl chains, as well as of molecular species with arachidonic acid (20:4n-6), whose higher content can contribute to a better adaptation of the mussel C. grayanus and of the sea urchin M. nudus and, thereby, to a longer lifespan. Conclusions: The lipidomic approach to studying the gerontological problem using sea urchins and bivalves as an example has revealed a clear relationship between the profile of molecular species of the membrane lipids and the lifespan. The exact mechanisms of this relationship need to be further clarified.","PeriodicalId":758,"journal":{"name":"Russian Journal of Bioorganic Chemistry","volume":"51 1","pages":"160 - 170"},"PeriodicalIF":1.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143396618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The structure of silver-modified powder cellulose isolated from hardwood lignocellu-lose was studied by X-ray structural analysis and computer simulation. Results and Discussion: A full-profile analysis showed that the studied sample belongs to the monoclinic phase of cellulose Iβ with an antiparallel arrangement of molecules, with the unit cell lattice parameters a = 7.881 Å, b = 7.837 Å, c = 10.603 Å, γ = 95.63°, and volume V = 652 Å3. The sizes of the coherent scattering regions (CSRs) of the sample were calculated by the Scherrer equation and used to analyze the supramo-lecular structure. An increase in the CSR in the [100] direction and a decrease in the CSR in the [001] direction compared to the respective parameters of powder lignocellulose were observed. The cross-sectional area of the fibril of the modified sample in the ab plane (980 Å2) was found to be ~8% larger than that of powder cellulose. The crystallinity index (CI) calculated by the Ruland method estimated at 79% which was 7% higher than that of powder cellulose.

The object of our study was the dioxane lignin isolated from wheat straw. The conversion of wheat straw dioxane lignin in a sub/supercritical dimethyl carbonate medium was studied. Methods: The experiment was performed in an autoclave in a temperature range from 200°C to 350°C. The low-molecular-weight products were extracted from the liquid fraction using hexane; GC-MS was used to study their composition. The solid products were analyzed by IR spectroscopy. Results and Discussion: The low-molecular-weight products consist of esters, aldehydes, ketones, and alkyl aromatic compounds. Thirty-four compounds were identified by GC-MS, including 12 C6–C3 compounds, i.e., those whose structures match the generally recognized phenylpropane unit of lignin. The low-molecular-weight products fraction is predominantly comprised of methyl esters of aromatic and fatty acids. More than 95% of the identified low-molecular-weight products are veratric-type compounds. New data on the conversion undergone by the wheat straw dioxane lignin in a sub/supercritical dimethyl carbonate medium were obtained. It was shown that high solubility of dioxane lignin under subcritical conditions may be due to cleavage of intermolecular interaction, including hydrogen bonds between the dioxane lignin macromolecules, as a result of thermal exposure and methylation reactions. Fragmentation of the dioxane lignin macromolecules under supercritical conditions involves the processes of radical cleavage of the alkyl aryl ether bonds, as well as the dealkylation, dehydration, methylation, transesterification, and demetoxylation reactions. Conclusions: New data on the conversion of wheat straw dioxane lignin in a sub/supercritical dimethyl carbonate medium were obtained.","PeriodicalId":758,"journal":{"name":"Russian Journal of Bioorganic Chemistry","volume":"50 7","pages":"2781 - 2786"},"PeriodicalIF":1.1,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
