Цель исследования — анализ влияния десяти 6-часовых циклов воздействия высоких концентраций (16 мкг/мл) гентамицина in vitro на изменение фенотипа и генотипа аминогликозидочувствительных штаммов S.aureus, относящихся к четырём сиквенс-типам: ST5 (ATCC 29213), ST8, ST97 и ST22 (MRSA). Для всех штаммов, кроме ATCC 29213, после селекции отмечалось увеличение МПК гентамицина до 8–64 мкг/мл. Один штамм (SA0937) диссоциировал на три морфотипа, включая мелкоколониевый вариант (small colony variant, SCV). Вариант производного штамма SA0937 с колониями нормального размера характеризовался ассоциированной устойчивостью к даптомицину за счёт мутации P314L в MprF. Формирование устойчивости не сопровождалось изменением скорости роста, кроме морфотипа SCV. Для штамма ATCC 29213 после селекции отмечалось появление толерантности, проявляющейся в увеличении эффективного киллинга до 14 ч в 24-часовом time-killing эксперименте с концентрацией антибиотика 16 мкг/мл. У штамма ATCC 29213 выявлены мутации в пептидил т-РНК гидролазе (Pth). У трёх штаммов были обнаружены делеции в гене atpG, входящим в состав АТФ-синтазного комплекса. У остальных производных штаммов были выявлены делеции и мутации в генах метаболизма менахинона hepS, menA и трансляционном факторе элонгации G (fusA). Таким образом, использование гентамицина сопряжено с возможным быстрым формированием устойчивости и толерантности, не связанными с приобретением генов аминогликозид-модифицирующих ферментов. Выявление SCV ассоциировано с неблагоприятными клиническими исходами. При использовании комбинированной терапии необходимо учитывать, что существует возможность формирования устойчивости к даптомицину на фоне селекции гентамицином.","PeriodicalId":8471,"journal":{"name":"Antibiotics and Chemotherapy","volume":"225 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139622624","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 modern healthcare system is constantly improving and introducing new measures to protect the population from viral diseases, but the experience of the COVID-19 pandemic has shown that infections cannot always be controlled on global scale. In this regard, the development of new broad-spectrum antiviral drugs is more relevant than ever.The aim of the study was to investigate the antiviral activity and cytotoxicity of copolymers of sodium styrene sulfonate and vinyl monomers of various chemical structures, as well as to identify promising polymers for the development of new antiviral agents.Materials and methods. 14 copolymers of sodium styrene sulfonate (NaSS) with various functional comonomers were synthesized. Three viruses with different reproduction strategies and transmission methods — respiratory syncytial virus, influenza virus, and herpes virus — were selected for the assessment of antiviral activity.Results. The screening identified copolymers that showed high activity against all three viruses. It was found that the introduction of various functional groups into the structure of NaSS did not decrease antiviral activity, but significantly reduced cytotoxicity. The molecular weight has also shown a noticeable effect on the activity. Different sensitivity of viruses and cells to the studied polymers was revealed, likely due to the structural features of the virus shell and cell wall.Conclusions. The results demonstrate the potential of sodium styrene sulfonate copolymers as a model for developing a broad-spectrum antiviral drug.","PeriodicalId":8471,"journal":{"name":"Antibiotics and Chemotherapy","volume":"2 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139529351","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}

Purpose. Assessment of acute toxicity of the quinazoline derivative 3-[2-oxo-2-(4-phenylpiperazine-1yl)ethyl] quinazoline-4(3h)-oh, exhibiting antimicrobial activity. Material and methods. All experiments were carried out on non-linear mature female rats with a body weight of 180–190 g. Female individuals were in the diestrus stage. The rats were divided into groups (n=6) by a random sample, there were 4 individuals in each group and were kept in cages for a week before the experiment, getting used to laboratory conditions: animals receiving intragastric equiobjection of distilled water (control); experimental animals treated with the compound VMA-10-21 at doses of 1000, 2000; 5000 mg/kg (the doses were selected based on the fact that the study of the toxicity of pyrimidine derivatives with a similar chemical structure showed their relative safety and the absence of lethality from a dose of 500 mg/kg). Results. Assessment of acute toxicity of the quinazoline derivative 3-[2-oxo-2-(4-phenylpiperazine-1yl)ethyl]quinazoline-4(3h)-oh with intragastric administration showed that this compound belongs to class 5 toxicity and is low-toxic according to. Under these conditions, and for LD₅₀, the maximum dose is 5000 mg/kg. However, despite the results obtained, when this compound was administered at a dose of 5000 mg/kg, changes in hemoglobin, the number of leukocytes and platelets, as well as total protein were observed, which may indicate the possible development of pathological changes in the hematopoietic and hepatobiliary systems. Conclusion. Thus, the quinazoline derivative 3-[2-oxo-2-(4-phenylpiperazine-1yl)ethyl]quinazoline-4(3h)-oh with intragastric administration is low-toxic and belongs to the 5th class of toxicity, and therefore the maximum dose is 5000 mg/kg for LD₅₀. However, given the fact that there are changes in hematological and biochemical parameters, this compound needs to be studied in detail under the conditions of course effects on the body of animals.","PeriodicalId":8471,"journal":{"name":"Antibiotics and Chemotherapy","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89792356","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 requirements of modern clinical guidelines for the treatment of respiratory viral infections suggest the possibility of identifying a specific viral pathogen. In this regard, the search for drugs with selective activity against respiratory syncytial virus and parainfluenza virus is relevant. The purpose of the work is to study the antiviral activity of the drug Cytovir®-3 in vitro in relation to the cytopathogenic effect of respiratory viruses (parainfluenza virus and respiratory syncytial virus). Material and methods. The antiviral effect of Cytovir®-3 in comparison with Umifenovir against parainfluenza virus and respiratory syncytial virus was studied on Vero cell culture. Drugs were administered 1 hour before (prophylactic regimen) and 1 hour after (treatment regimen) infection of the cell culture with respiratory viruses. The working range of concentrations of the studied drugs was calculated based on the values of 50% cytotoxic concentration calculated based on the results of a quantitative microtetrazole test. Results and discussion. The drug Cytovir®-3 in two schemes of application (therapeutic or prophylactic) showed its antiviral efficacy in vitro against respiratory syncytial virus and parainfluenza virus due in the non-toxic range (0–794 µg/ml). At the same time, the suppressive effect of the drug Cytovir®-3 against the parainfluenza virus begins at lower concentrations of the drug with its early (preventive) introduction into cell culture (250 mcg/ml). Conclusion. Antiviral activity of Cytovir®-3 has been proven in vitro against parainfluenza virus and respiratory syncytial virus. At the same time, in all series of experiments, Cytovir®-3 had a higher index of selectivity of antiviral action than that of the comparison drug Umifenovir.","PeriodicalId":8471,"journal":{"name":"Antibiotics and Chemotherapy","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75311053","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}
