Material and methods. The study of urine samples of 4F-MDMB-BICA cannabimimetic users using enzymatic hydrolysis in combination with solid-phase extraction and gas chromatography with mass spectrometric detection showed that the 4F-MDMB-BICA marker and, in some cases, its nor-metabolite are detected in the urine of consumers. The 4F-MDMB-BICA nor-metabolite is a common biotransformation product for the cannabimimetics 4F-MDMB-BICA and 5F-MDMB-PICA, resulting from the hydrolysis of the ester bond and N-dealkylation of the heterocyclic core. Results. 35 compounds were identified by liquid chromatography with tandem mass spectrometry, including the original parent 4F-MDMB-BICA, 31 metabolites of biotransformation phases I and II, and 3 metabolite artifacts; it was found that the latter are the product of intramolecular cyclization of 4F-MDMB-BICA metabolites. 16 previously undescribed compounds, including 15 metabolites and one artifact were identified. The putative structures, mass spectra and some characteristics of the identified compounds are given, including retention time, MRM transitions, and relative peak area of the substance. Conclusion. From the presented data, it can be seen that the main pathways of 4F-MDMB-BICA metabolism in the human body are hydrolysis of the ester group, hydroxylation of alkyl radicals and the heterocyclic core, oxidative defluorination, and N-dealkylation. The hydrolysis products of the ester bond and hydroxyl derivatives are subsequently conjugated with glucuronic acid.","PeriodicalId":20508,"journal":{"name":"Problems Of Biological, Medical And Pharmaceutical Chemistry","volume":"90 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140462629","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}

Coronary heart disease (CHD), leading among the causes of death in adulthood and old age, is an urgent medical and social problem. The pathogenesis of most forms of coronary heart disease is based on stenosing atherosclerosis of the coronary arteries, which develops against the background of dyslipidemia and arterial hypertension and is accompanied by the activation of immunocompetent cells (ICCs) of the vascular wall with the development of a subclinical inflammatory reaction, as well as the production of pro-inflammatory factors such as interleukins, chemokines, growth factors and etc. In turn, ICC activity is determined by the state of their intracellular molecular cascades, which transmit signals into the cell and ensure its reactivity to various external stimuli, such as mitogens, cytokines, pathogen components, etcIt has been shown that the central nervous system plays an important role in the regulation of ICC activity due to the production of neurohumoral molecules, such as melatonin, endorphin, sero-tonin, etc., which ensure the coordination of immune responses and their control by the central nervous system. The aim of this study was to study the relationship between melatonin production and intracellular factors that regulate the pro-inflammatory activi-ty of whole blood mononuclear cells and their metabolism in patients with coronary artery disease. Material and methods. As part of the cohort study, 58 patients of both sexes with coronary artery disease aged 49 to 67 years and 20 practically healthy individuals of both sexes were examined. In accordance with the purpose of the study, the concentration of focal adhesion protein kinase (FAK), 5'AMP-activated protein kinase (AMPK), AKT1 protein kinase, signal transducers and transcription activators (STAT) was determined in nuclear cy-toplasmic lysates of whole blood mononuclear cells: STAT3, STAT5A and STAT6, c-Jun N-terminal protein kinase 1 and 2 isoforms (JNK), mitogen-activated protein kinase p38 (p38), extracellular growth kinase 1 and 2 isoforms (ERK), Janus kinase type 2 (JAK2), nuclear transcription factor NF -kB, caspase-1, cyclooxygenase-2 (COX-2), p70-S6K1 protein kinase, p53, p27, p21 proteins.

Alzheimer's disease is one of the most common forms of dementia, the pathogenesis of which is based on the accumulation of β–amyloid plaques in brain structures and the development of cholinergic deficiency. The aim of the study was to evaluate the effect of chalcone analogues on the change in acetylcholinesterase activity and the process of β-amyloid aggregation in vitro. Material and methods. The tested compounds were six bis-substituted chalcone analogues, which were dissolved in dimethylsulfoxide during the analysis to obtain double dilutions. The effect of the studied substances on the activity of acetylcholinesterase was evaluated by the modified Ellman method. The change in the aggregation process of β-amyloid particles was determined in reaction with congo red after 3, 6 and 9 days of incubation. Based on the obtained results of the «% inhibition- concentration» relationships, the IC50 index was calculated, which was expressed in mmol/ml. Results. In the course of the study, it was shown that the analyzed chalcone analogues inhibit the aggregation of β-amyloid particles starting from the 6th day of incubation with a maximum on the 9th day. At the same time, the compounds that showed the highest level of activity were trimethoxy-substituted substances under the codes AZBAX4 and AZBAX6, whose IC50 on the 9th day of the study was 21.4±0.928 mmol/ml and 32.4±0.456 mmol/ml, respectively. Also, a high level of anticholinesterase properties was established for these compounds with IC50 of 35.9±0.991mmol/ml and 25.1±0.261 mmol/ml, respectively. The rest of the tested compounds showed a lower level of activity. Conclusion. The study showed that chalcone analogues under the codes AZBAX4 and AZBAX6 inhibit the activity of acetylcholinesterase and the pro-cess of aggregation of β-amyloid in vitro, which makes these compounds promising for further study in order to develop medicines for the pathogenet-ic treatment of Alzheimer's disease.","PeriodicalId":20508,"journal":{"name":"Problems Of Biological, Medical And Pharmaceutical Chemistry","volume":"174 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140462313","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}

Infantile hemangiomas are the most common soft tissue tumors occurring in 4-10% of children under the age of 1 year. Various methods are used to treat the disease: laser therapy, surgical exci-sion, cryodestruction, sclerosing, as well as conservative treatment with systemic glucocorticosteroids and beta-blockers administered enterally, topi-cally, and externally. Pharmacotherapy with the use of application dosage forms of beta-receptor antagonists is considered to be the most effective and safe method. This approach to treatment has several advantages over the oral method of administration: first, the convenience and painlessness of use, and secondly, the local effect on the pathological process, hence reducing the risk of systemic side effects (bradycardia, hypotension, bron-chospasm, insomnia). All these advantages emphasize the relevance of the development of soft dosage forms of beta-blockers. The patent RU 2471500 C2 “Use of beta-blocker for preparing drug for treating hemangiomas” proposes atenolol, betaxolol, bisoprolol, carvediol, metoprolol, nebivolol, propranolol and sotalol as antiangiogenic agents.
