Microscopic analysis of Valeriana stolonifera and Valeriana collina leaves

V. I. Kokitko — 2024-11-08

Plants of the Valeriana species are distributed in various parts of the world, especially in Europe and Asia. A high content of polyphenolic compounds, including flavonoids and hydroxycinnamic acids with expressed biological activity, was previously identified within the herb of the studied Valeriana species. Morphological and anatomical data can be used in phylogenetics of species and genera to find out diagnostic and age-related characteristics of plants. This led us to microscopic studies of aerial organs of the above-mentioned Valeriana species.

The aim of the work is to conduct a comparative study of the diagnostic features within the morphological and anatomical structure of Valeriana stolonifera and Valeriana collina leaves.

Materials and methods. Both raw and dried plant material of V. stolonifera and V. collina was used for microscopic studies. Temporary micropreparations were made using generally accepted methods. The anatomical features of the raw material were examined using Carl ZEISS “AxioStar Plus” and “Primo Star”.

Results. The study identified key morphological and anatomical features of the species, which should be considered for the identification and standardization of promising medicinal plant materials and within the development of methods of analytical and regulatory documentation.

Conclusions. The key microscopic differences in the leaves of the studied species lie in the structure of the adaxial and abaxial surfaces of the leaf blade. The upper epidermis consists of large elongate cells with wavy walls. The cells of the lower epidermis are smaller and have more sinuous walls compared to the upper epidermis cells. The degree of wall sinuosity varies between species – V. collina is characterized by more sinuous cells in both the upper and lower epidermis compared to V. stolonifera. The absence of stomata on the upper epidermis is a common feature for both species.

I. M. Bilai — 2024-11-08

The activation of lipid free radical oxidation is a key stage in the development of many diseases and can lead to the emergence of related complications. To identify new synthetic compounds with antioxidant properties, it is necessary to conduct studies on various models of experimental free radical oxidation of biomolecules. Literature sources indicate that among the derivatives of 1,2,4-triazole, there is a significant number that possess high antioxidant activity.

The aim of the study to assess the antioxidant properties of newly synthesized S-derivatives of 1,2,4-triazole through the inhibition of reactive oxygen species accumulation in the superoxide dismutase system.

Materials and methods. To achieve this goal, we used one of the methods for assessing antioxidant activity by initiating free radical processes in vitro, specifically by inhibiting the accumulation of reactive oxygen species.

Results. Twenty-three S-derivatives of 5-(thiophene-3-ylmethyl)-4-R-1,2,4-triazole-3-thiols were investigated. The most effective compound was sodium 2-((4-phenyl-5-thiophene-3-ylmethyl)-1,2,4-triazole-3-yl)thio)acetate, which exceeded the activity of both reference drugs. Following in activity was compound 22, 1-phenyl-2-((4-phenyl-5-(thiophene-3-ylmethyl)-4H-1,2,4-triazole-3-yl)thio)ethanol, which demonstrated an effect similar to that of emoxipine, while compound 7, 1-(3-fluorophenyl)-2-((5-thiophene-3-ylmethyl)-4H-1,2,4-triazole-3-yl)thio)ethanone, was slightly less active.

Conclusions. It was established that among the new S-derivatives of 1,2,4-triazole, some exhibit significant antioxidant effects that are comparable to or exceed the efficacy of reference drugs.

Research on the pharmacological potential of 1-alkyl derivatives of 3,5-dimethyl-4-((4-nitrobenzylidene)amino)-1,2,4-triazolium bromide

O. I. Panasenko — 2024-11-08

The heterocyclic system of 1,2,4-triazole and its derivatives is one of the leaders in the development of highly promising biologically active compounds. The peculiarities of the chemical structure of the derivatives of this heterocycle provide a wide range of possibilities for chemical transformations that allow to obtain really effective drugs. The involvement of several substituents in chemical transformations simultaneously, which have the properties of highly reactive centers, additionally creates favorable conditions for the formation of rational ways to create a biologically active compound. Amino-, mercapto- or hydroxogroups often play the role of such groups in chemistry. The use of these groups as substituents of 1,2,4-triazole synthon provides multifaceted opportunities for directed chemical transformation. The ability of such structural fragments to form chemical interactions and bonds with biological targets has an additional positive effect in the sense of their involvement in chemical transformations on the way to the targeted production of a biologically active substance. Thus, the combination of a heterocyclic structure with a highly reactive chemical center is endowed with theoretically sound and practically significant meaning.

The aim of the work is to preliminary determine the potential for creating a biologically active substance with antifungal action based on 1-alkyl derivatives of 3,5-dimethy-l-4-((4-nitrobenzylidene)amino)-1,2,4-triazolium bromide.

Materials and methods. The toxicity of the studied compounds has been predicted using the TEST program (Toxicity Estimation Software Tool), which allowed to determine the predictive level of acute toxicity, ecotoxicity and mutagenicity. The physicochemical and pharmacokinetic parameters have been predicted, and the drug-like properties and availability of the investigated substances have been assessed using the online resource SwissADME. The determination of the most favorable spatial configuration of the ligand relative to the active site of the protein and the assessment of the strength of their interaction have been realized using the computational method of molecular docking. The ligands have been prepared using MarvinSketch 6.3.0, HyperChem 8 and AutoDock Tools-1.5.6 software. The preparation of the model enzyme has been based on the use of Discovery Studio 4.0 and AutoDock Tools-1.5.6. The practical implementation of flexible molecular docking has been carried out using the software tools of the AutoDock/Vina platform.

Results. In the process of step-by-step prescreening of the formed structures of a number of 1-alkyl derivatives of 3,5-dimethyl-4-((4-nitrobenzylidene)amino)-1,2,4-triazolium bromide, a number of qualitative and quantitative indicators related to the physicochemical characteristics and pharmacokinetic parameters of the studied substances have been obtained. According to the results of the first stage of research, the group of substances under consideration can be predictively considered low-toxic, but with a high risk of mutagenic properties. The next stage of the work, which involved the analysis of physicochemical parameters, pharmacokinetic parameters, general drug-like properties and bioavailability, allowed us to identify 1-alkyl derivatives of 3,5-dimethyl-4-((4-nitrobenzylidene)amino)-1,2,4-triazolium bromide as substances with a rather positive pharmacological profile. The final stage in the form of molecular docking of the structure of the studied compounds to the active site of lanosterol 14α-demethylase allowed us to determine the nature of the chemical interaction and the type of amino acid residues that may be involved in the antifungal properties of the key ligands. The analysis of the docking results allows us to determine the privileged nature of the nonyl substituent at the first Nitrogen atom of the 1,2,4-triazole synthon in the structure of the presented series of compounds for the formation of antifungal properties.

Conclusions. The general prospects for the creation of a biologically active substance with antifungal properties using 1-alkyl derivatives of 3,5-dimethyl-4-((4-nitrobenzylidene)amino)-1,2,4-triazolium bromide look quite realistic. Particular attention should be paid to 3,5-dimethyl-1-nonyl-4-((4-nitrobenzylidene)amino)-1,2,4-triazolium bromide as a substance with significant potential for antifungal properties, which allows us to recommend this compound for further more constructive and extended in vitro and in vivo studies.

QSAR prediction of toxicity for a new 1,2,4-triazole derivatives with 2-bromo-5-methoxyphenyl fragment

M. P. Skoryi — 2024-11-08

New derivatives of 1,2,4-triazole are promising research targets due to their unique biological properties, including antimicrobial, antifungal, antitumor, and antioxidant activities. The introduction of the 2-bromo-5-methoxyphenyl fragment into the triazole structure potentially enhances these properties. However, the issue of toxicity for such compounds remains a critical factor for their further application. To reduce experimental costs and time, QSAR (Quantitative Structure-Activity Relationship) methods are widely applied, allowing to predict compounds toxicity based on their molecular structure.

The aim of this study was to evaluate the toxicity of new derivatives of 5-(2-bromo-5-methoxyphenyl)-4-R-1,2,4-triazole-3-thiols, their acids, and esters using the QSAR method to predict parameters of acute toxicity (LD₅₀) and to assess the influence of various radicals on the toxicity of the compounds.

Materials and methods. The objects of this study were derivatives of 5-(2-bromo-5-methoxyphenyl)-4-R-1,2,4-triazole-3-thiols, synthesized at the Department of Toxicological and Inorganic Chemistry of Zaporizhzhia State Medical and Pharmaceutical University. The nearest neighbor method was used for toxicity evaluation, applying the Toxicity Estimation Software Tool (TEST). The prediction of rats lethal dose (LD₅₀) was based on the structural similarity of the studied compounds with known substances that have experimental toxicity data.

Results. The QSAR analysis revealed that structural modifications in the derivatives of 5-(2-bromo-5-methoxyphenyl)-4-R-1,2,4-triazole-3-thiols significantly influence their toxicity. Specifically, increasing the size of the radicals, especially through the introduction of aromatic fragments, contributed to the enhanced safety of the compounds, as evidenced by the increase in LD₅₀values. The highest LD₅₀values were observed for compounds containing phenyl radicals.

Conclusions. The results of this study indicate the feasibility of using QSAR models to predict the toxicity of 1,2,4-triazole derivatives containing a 2-bromo-5-methoxyphenyl fragment. The observed trend of increasing safety with the introduction of larger aromatic radicals can be used for the rational design of new compounds with improved toxicological properties.

Computer prediction of acute toxicity of thioderivatives of 3,5-bis(5-mercapto-4-R-4H-1,2,4-triazol-3-yl)phenol

K. K. Isaicheva — 2024-11-08

This study presents the computational prediction of acute toxicity for new derivatives of 3,5-bis(5-mercapto-4-R-4H-1,2,4-triazol-3-yl)phenols and their alkylated analogues.

The aim of the work was to evaluate the impact of structural changes, particularly alkylation and chain length extension, on the toxicity levels of new derivatives of 3,5-bis(5-mercapto-4-R-4H-1,2,4-triazol-3-yl)phenols and their alkylated analogues.

Materials and methods. QSAR methodologies were used to predict toxicity, allowing the evaluation of toxicological properties based on molecular descriptors. Toxicity modeling was performed using computer software, enabling the estimation of toxicity without the need for in vivo experimental studies.

Results. The results showed, that alkylation of 3,5-bis(5-mercapto-4-R-4H-1,2,4-triazol-3-yl)phenol derivatives does not lead to a significant toxicity reduction. Moreover, an increase in toxicity was observed with the prolongation of the carbon chain in the synthesized compounds. It was also found, that acid derivatives, particularly 2,2’-(((5-hydroxy-1,3-phenylene)bis(4-R-4H-1,2,4-triazol-5,3-diyl))bis(sulfanyl))diacetate acids and 3,3’-((((5-hydroxy-1,3-phenylene)bis(4-R-4H-1,2,4-triazol-5,3-diyl))bis(sulfanyl))bis(methylene))dibenzoyl acids, exhibit toxicity ranging from 521.9 mg/kg to 2232.2 mg/kg, corresponding to toxicity class IV (low toxicity) on the OECD scale. It was found, that molecular structure and hydrophobic properties play a crucial role in determining compound toxicity. This study helps to establish a structure-toxicity relationship and to optimize compound structures for reduced toxicity.

Conclusions. These results provide a foundation for further development of potential drug candidates with predicted toxicological properties.

In silico prediction of the pharmacological potential of new 7-alkyl-8-hydrazine derivatives of 1,3-dimethylxanthine

L. M. Mosula — 2024-11-08

The development of new drug-like molecules based on 7-R-8-hydrazine derivatives of 1,3-dimethylxanthine is promising in view of the known pharmacological effect of theophylline and functional hydrazine derivatives. In silico methods make it possible to rationalize the synthesis and reduce the number of chemical compounds at the stage of virtual screening by eliminating potentially ineffective molecules.

The aim of the work was to carry out а virtual design and predictive evaluation of pharmacological activity of new 7-alkyl-8-hydrazine derivatives of 1,3-dimethylxanthine by in silico methods.

Materials and methods. To perform in silico prediction of the pharmacological potential of several new 7-alkyl-8-hydrazine derivatives of 1,3-dimethylxanthine, we used the online services. As 12 model compounds, we chose 12 derivatives of 5-(2-(1,3-dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-yl)hydrazine)-5-phenylpentanoic acid with linear and branched alkyl substituents at the 7^th position of the basic heterocycle: methyl-, ethyl-, n-propyl-, n-butyl, i-butyl, n-amyl, i-amyl, n-hexyl, n-heptyl, n-octyl, n-nonyl, n-decyl. The use of the freely available web tool SwissADME made it possible to calculate physicochemical parameters and to determine the drug-likeness properties of molecules. And other Internet platforms allowed to predict the spectrum of biological activity of the target compounds.

Results. In silico analysis of the pharmacological potential of model compounds was performed. Three biological actions (peripheral vasodilator, kidney function stimulant, lipoprotein lipase inhibitor) with high Pa values are predicted for all derivatives of the series. The ADME parameters of the molecules were evaluated and their potential drug-like properties were determined.

Conclusions. It was established that the extension of the alkyl substituent at the 7^th position of the basic heterocycle should lead to a deterioration of the ADME parameters of the molecules, potentially reduce their oral bioavailability, but should not radically affect their biological activity profile. Compounds 1–3 and 5 are predicted to be orally bioavailable. They should be characterized by a wide spectrum of biological activity with the highest probability of vasodilator effect on peripheral vessels. In the future, it is advisable to carry out targeted synthesis of hit compounds and thorough in vitro, in vivo studies, and for compounds with violated physicochemical criteria – structural optimization of molecules in order to find a lead compound.

Computer prediction of toxicity of new S-alkyl derivatives of 1,2,4-triazole

V. V. Kalchenko — 2024-11-08

1,2,4-Triazole derivatives are of researchers’ significant interest due to their diverse biological properties, such as antimicrobial, anti-inflammatory, anticancer, and antioxidant activities. The integration of a 2-bromo-4-fluorophenyl fragment into the triazole structure can significantly enhance these activities. However, the evaluation of the toxicity of such compounds remains a critically important aspect for their practical application. To reduce the time and cost of experimental studies, QSAR (Quantitative Structure-Activity Relationship) methods are actively used, allowing the prediction of toxicity based on the molecular structure of compounds.

Aim of the study. To assess the toxicity of new S-derivatives of 5-(2-bromo-4-fluorophenyl)-4-R-1,2,4-triazol-3-thiols using the QSAR method, specifically to predict acute toxicity parameters (LD₅₀), and to determine the influence of different (length) radicals on the toxicity of these compounds.

Materials and methods. The objects of the virtual study were derivatives of 5-(2-bromo-4-fluorophenyl)-4-ethyl-1,2,4-triazol-3-thiols. They were evaluated at the Department of Toxicological and Inorganic Chemistry of the Zaporizhzhia State Medical and Pharmaceutical University. The toxicity assessment was conducted using the nearest neighbor method via the Toxicity Estimation Software Tool (TEST). The prediction of the lethal dose (LD₅₀) for rats was based on the structural similarity of the studied compounds with known substances, for which experimental toxicity data are available.

Results. The conducted QSAR analysis demonstrated that structural changes in S-derivatives of 5-(2-bromo-4-fluorophenyl)-4-ethyl-1,2,4-triazol-3-thiols significantly affect the predicted toxicity. The primary factor influencing the changes in LD₅₀ values is the variation of radicals at the 5th position of the triazole ring.

Conclusions. The results of the study showed, that the toxicity of new S-alkyl derivatives of triazol-3-thiols depends on the type of alkyl substituent. Compounds with propyl to heptyl fragments exhibit increased toxicity, while derivatives with thiol, octyl, nonyl, and decyl residues are characterized by lower toxicity.

Peculiarities of the course of gestation in women with a history of reproductive loss

V. H. Siusiuka — 2024-11-08

Aim. Тo assess the frequency of extragenital pathology, features of obstetric and gynecological history and the course of pregnancy in women with a history of reproductive loss.

Materials and methods. The study was conducted on the basis of the Municipal non-profit enterprise “Maternity house No. 9” of the Zaporizhzhia City Council with the involvement of 75 pregnant women with one reproductive loss in history. The control group consisted of 30 women without a history of reproductive loss. Women who had reproductive losses were divided into 2 groups. Group I (main group) includes 38 pregnant women who registered for pregnancy and began their participation in this study after the start of a full-scale war on the territory of Ukraine. II (comparison) group included 37 women who were registered for pregnancy before the start of the full-scale war. It should be noted that 17 pregnant women (44.7 %) had the status of an internally displaced person. The average age of women in group I was 30.10 ± 5.86 years, in group II – 28.80 ± 6.07 years, and 26.50 ± 4.95 years in the control group. The anamnesis data and features of the course of gestation were studied in all patients. Management of pregnancy and childbirth of women was carried out in accordance with the current Orders of the Ministry of Health of Ukraine. Variational and statistical processing of the results was carried out using the Statistica 13 program.

Results. According to the results of the study, it was established that the frequency of extragenital pathology in women with one reproductive loss was higher, compared to women who had no such experience. Diseases of the cardiovascular and urinary systems occupy a leading place in this category of women. According to obstetric and gynecological anamnesis, a significant predominance among women of I and II groups of diseases of the reproductive system, compared to women of the control group, was established. Also, in the corresponding groups, a high frequency of miscarriage was established both in the period up to 12 weeks (28.95 % in the I group, 43.2 % in the II group against 6.67 % in the control group), and in the period of 12–22 weeks (34.20 % in the I group, 29.73 % in the II group vs. 13.33 % in the control group).

Conclusions. Based on the conducted analysis, a high frequency of pregnancy complications was established for pregnant women who had a history of one reproductive loss. This contingent of women also has a high frequency of extragenital and gynecological concomitant pathology. Such results make it possible to assume a connection between the presence of one reproductive loss in women in the anamnesis and gestational complications of the next pregnancy.

Determination and analysis of gene expression involved in glucose metabolism under the conditions of the development of experimental diabetes of dexamethasone type (type 2 diabetes)

T. V. Ivanenko — 2024-11-08

Type 2 diabetes is one of the most common and serious chronic diseases today, which has become a global health care problem. Type 2 diabetes accounts for about 90–95 % of all cases of diabetes and significantly affects patients’ quality life due to the development of numerous complications, such as cardiovascular diseases, chronic renal failure, retinopathy, neuropathy. Modern research in the field of diabetology pays considerable attention to the understanding of the genetic mechanisms of the pathogenesis of type 2 diabetes, which makes it possible to develop new approaches to its diagnosis and treatment. Individualization of laboratory diagnostics and treatment, which considers the genetic, metabolic and clinical characteristics of each patient, is a key direction in improving the effectiveness of the treatment of type 2 diabetes. Type 2 diabetes is a complex polygenic disease, that develops under the influence of both genetic and external factors, which requires an integrated approach to its diagnosis, treatment and prevention. Taking into account the constant increase in the prevalence of this disease, the relevance of scientific research in this area is beyond doubt. The development of new pharmacological agents, improvement of laboratory diagnostic strategies and individualization of treatment are key directions for overcoming the problem of type 2 diabetes and improving the quality of life of patients.

The aim of the work: identification and analysis of genes panel, involved in glucose metabolism under the conditions of the development of experimental type 2 diabetes.

Materials and methods. Analysis of the gene expression, involved in glucose metabolism was performed using the real-time reverse transcription polymerase chain reaction method CFX-96 Touch™ (Bio-Rad, USA) using the RT2Profiler™ PCR Array Rat Diabetes kit (QIAGEN, Germany).

Results. Based on the results of the PCR study, the activity of the studied genes involved in glucose metabolism can be divided as follows: G6pc, Gpd1 – genes with high expression compared to the control group of animals; Ace, Acly, Foxg1, Foxp3, Gcgr, Gck, Gsk3b, Hmox1, Pygl, Snap23, Snap25 – genes with low expression compared to the control group of animals; Cebpa, Dpp4, Sell – genes in which no changes were detected in the samples in relation to the control group of animals; Ccr2, Fbp1, Gcg – genes, whose expression was not detected.

Conclusions. The development of dexamethasone type 2 diabetes significantly (where ∆∆Ct <30) increases the expression of Gpd1 genes by 8 times and G6pc by 2 times compared to the control group of animals. During the development of type 2 dexamethasone diabetes, significantly (where ∆∆Ct <30) the Gsk3b and Hmox1 genes had a 17-fold low expression; Pygl at 11; Foxg1 in 7; Gck in 6; Ace and Foxp3 in 4; Acly in 3; Gcgr, Snap23, Snap25 in 2 times compared to the control group of animals. The expression of Ccr2, Fbp1, Gcg genes during the development of type 2 dexamethasone diabetes was not detected.

Research on current issues of self-medication among young people

N. O. Tkachenko — 2024-11-08

The aim of the work is to determine the prevalence of self-medication among young people and their attitude to it, with the further development of recommendations for pharmacists regarding the prevention of negative consequences of self-medication and the improvement of pharmaceutical assistance (educational activities) in matters of responsible self-medication.

Materials and methods. The work used methods of information search, survey, critical analysis, generalization, and interpretation of results. The survey took place online from January to May 2024, using the developed questionnaire (the electronic version was created using Google Forms). A total of 207 questionnaires were received from people aged 20–25.

Results. Mostly, it is difficult for young people to determine their attitude toward self-medication. During treatment, a large number of research participants use the advice of doctors and pharmacists. 75.8 % of respondents always study the instructions for the medical use of drugs before using them. Basically, young people do not increase the dose of drugs arbitrarily to speed up their recovery. Almost half of them do not change the prescribed medications by the doctor to cheaper analogs. According to the research participants, half of them consider an adequate amount of drugs in the form of two names, and this is confirmed by the fact that 83.6 % of them had cases of simultaneous administration of more than one drug. After undergoing self-treatment, 75.8 % of respondents consider it not always practical, among which 13.5 % indicate that it was necessary to consult a doctor.

Conclusions. The prevalence and attitude toward self-medication among young people were studied. The main reasons for self-medication are the difficulty of getting to a doctor’s appointment and lack of time, as well as the reduction of disease symptoms after self-diagnosis and the use of drugs and preventive measures. It should be noted, that 23.2 % of young people nevertheless turned to a doctor after receiving negative manifestations of self-medication, and half of the respondents shared their experience of self-medication. The obtained information can be useful for pharmacy institutions, which can use it to create a comprehensive model of a program for the prevention of negative consequences of self-medication, especially among young people, and increase patients’ commitment to the pharmaceutical enterprise.

Health-preserving physical culture and wellness competences as an important condition for ensuring and spreading a high level of public health (methodological aspects)

A. M. Hurieieva — 2024-11-08

WHO indicates that the purpose of actions aimed at strengthening public health protection is to ensure conditions under which people can remain healthy, able to strengthen health and well-being, and prevent deterioration of health. However, in the basic documents, there is no place for health-preserving physical culture and health-improving competencies of a person in the system of general efforts.

The aim of the work is to reveal the need and place of health-preserving physical culture and wellness competencies of a person as a condition for ensuring and spreading a high level of public health in Ukraine.

Material and methods. The study was organized at the Dnipro State Academy of Physical Culture and Sports, the Ukrainian State University of Science and Technology, the National Technical University “Dnipro Polytechnic” (all in Dnipro) and the Zaporizhzhia State Medical and Pharmaceutical University. The used methods of theoretical research were: study and generalization of data from domestic and foreign official and literary sources, as well as abstraction, analysis and synthesis, induction and deduction.

Results. Conceptual principles and didactic technology of physical education of a non-professional physical education (NpPhE), with an emphasis on strengthening the general cultural component of the educational component “Physical education” in higher education, aimed at eliminating existing shortcomings. Provided with pedagogical technology, NpPhE contributes to the formation of the building blocks of one’s own health. And the system of effective pedagogical mechanisms of NpPhE is significantly different from the provision of information about health, which is the subject of modern valeology. In this context, the development of conceptual directions of creative valeology is relevant, as a means of supporting a person’s creativity in a safe effect on health. Namely, the formation in institutions of higher education of the builders of their own health.

Conclusions. A system of pedagogical mechanisms is proposed, which is significantly different from just providing information about human health as a benefit/harm of influences and actions, which is what valeology is focused on. This is a prerequisite for the formation and development of creative concepts of modern valeology based on the improvement of cultural and practical components of the educational component “Physical education” in the conditions of a higher education institution for specialists who take care of building their own health from specialties related to civilians. In conditions where the majority of their graduates are engaged not in physical, but intellectual work, the further implementation of approaches related to professional-applied physical training for professional activities is something that it is time to abandon.

N. A. Bilousova — 2024-11-08

The implementation of the National Recovery Plan of Ukraine in the field of “Health Care”, namely the restoration of the pharmaceutical sector, improving the population’s access to medicines and their proper use, taking into account the regulatory and legal field harmonized with European legislation, in the context of providing the qualified pharmaceutical care and pharmaceutical services requires application of modern approaches based on evidence-based medicine and implementation in pharmaceutical practice. Patients with cardiovascular diseases, who are provided with medication under the Reimbursement Program and prescriptions from doctors, must be accompanied by pharmaceutical care based on evidence-based medicine to ensure proper use of drugs and rational pharmacotherapy.

The aim of the study was to investigate Ukrainian information and scientific databases, scientometric databases, i. e.: Embase, Web of Science, PubMed, and Cochrane Library to identify, generalize, and systematize scientific sources of medical and pharmaceutical data on providing patient-oriented pharmaceutical care to patients with coronary heart disease and predict the future vector of research on the specified topic.

Results. The analysis of the main strategies of providing pharmaceutical care to patients with cardiovascular diseases, in particular, coronary heart disease in pharmaceutical practice was carried out; the most researched clusters of providing pharmaceutical care were identified; modern trends and tendencies in the provision of pharmaceutical care to patients with coronary heart disease were summarized.

Conclusions. The development of providing qualified pharmaceutical care to patients with cardiovascular diseases is based on the principles of patient-oriented pharmacy and evidence-based medicine, which requires the design and implementation into the pharmaceutical practice of a sustainable conceptual model of providing patient-oriented pharmaceutical care by clinical pharmacists and pharmacists of pharmacy institutions with the expansion of the main roles, respectively the standards of Good Pharmacy Practice.

Pharmacogenetic testing: current state of the issue

O. V. Kraidashenko — 2024-11-08

Aim. The purpose of this work is to emphasize the importance and practical benefits of pharmacogenetics in medicine, demonstrating how the integration of pharmacogenetics into clinical practice can improve treatment outcomes and enhance the safety of therapies.

Pharmacogenetics is a rapidly developing branch of pharmacology that studies how genetic variation affects an individual’s response to drugs. By understanding these genetic differences, healthcare providers can tailor drug therapy to maximize efficacy and minimize adverse drug reactions. The field aims to move away from the traditional one-size-fits-all approach and instead personalize medical treatment based on a person’s genetic makeup. The ability to predict a person’s response to medication based on their genetic profile has profound implications. For example, pharmacogenetic testing can identify patients at risk for life-threatening adverse drug reactions, such as drug-induced liver injury. This proactive approach can prevent adverse events, improving patient safety and the overall quality of care. In addition, pharmacogenetics aids in the development of new drugs by identifying genetic markers associated with drug responses, optimizing the drug development process, and reducing the time and costs associated with bringing new drugs to market. Key advances in pharmacogenetics include the identification of genetic polymorphisms in enzymes, such as cytochrome P450, that affect drug metabolism, thereby influencing both safety and efficacy. Pharmacogenetic testing allows doctors to predict the best drug and dosage for a patient, improving treatment outcomes and reducing the risk of adverse drug events.

Despite its potential, the integration of pharmacogenetics into clinical practice faces challenges, including a lack of reliable clinical evidence, inadequate physician education, and the need for a comprehensive health IT infrastructure to support the use of genetic data. Ethical and legal issues, such as patient privacy and the risk of genetic discrimination, also present significant obstacles. However, continued research, the development of genetic testing technologies, and interdisciplinary collaborations are paving the way for more widespread adoption of pharmacogenetics, which promises to significantly improve patient care and healthcare efficiency. Key resources such as PharmGKB, CPIC, and the NIH provide valuable information and guidance for clinicians, researchers, and students, helping bridge the gap between genetics research and clinical application.

Conclusions. Pharmacogenetics represents a significant advancement in personalized medicine, offering the potential to tailor drug therapies to individual genetic profiles. Although the field has made substantial progress, challenges remain in the form of insufficient clinical evidence, implementation barriers, and ethical concerns. Continued research and collaboration among stakeholders are essential to fully realize the benefits of pharmacogenetic testing in clinical practice.

Bibliometric analysis of scientific literature on the use of suppositories in the treatment of prostate cancer patients

I. V. Bushuieva — 2024-11-08

Nowadays, cancer remains one of the main causes of death worldwide. Statistical data from various literary sources indicate that more than 130,000 people in Ukraine receive this diagnosis as a sentence every year. Cancer can affect any organs of the human body and, over time, the entire organism. In 2024, the agency of the World Health Organization on cancer and the International Agency of Cancer Research published the latest statistical estimates of this pathology in a global format, where prostate cancer is among the five most common oncological pathologies and takes the fourth place. Oncological diseases are one of the priority areas of healthcare development in accordance with the Order of the Ministry of Health of Ukraine No. 1832 dated 07.10.2022 “On Approval of Priority Areas of Healthcare Development for 2023–2025”. It was this fact that determined the choice of the direction of this research in the matter of finding information on the provision of pharmaceutical care, namely the use of a drug – a rectal suppository for the treatment of prostate cancer.

The aim of the work is to carry out a bibliometric analysis and further generalize the data of the scientific literature to study the prognostic value and features of the prescription of suppositories in the treatment of prostate cancer.

Materials and methods. The data search was conducted in the PubMed electronic database using the following key terms: “prostate cancer and suppositories”, “prostate cancer”. To monitor and analyze international scientific research, with the help of visualization tools and modern SciVal citation metrics using the online platform, bibliometric analysis can be performed. Using the VOSviewer functional program, bibliometric networks were constructed and visualized.

Results.
