Материал и методы. Исследование проводили на крысах-самцах, которые были разделены на четыре группы: контроль, получавший внутрижелудочно дистиллированную воду, и опытные группы животных, получавших внутрижелудочно суспендированные в дистиллированной воде соединения VMA–13–06, VMA–13–11 и VMA–13–12 в дозах 1/10 от молекулярной массы (39, 24 и 24 мг/кг соответственно) в течение 60 дней. С целью оценки возможного токсического повреждения печени определяли биохимические показатели крови: активность АлАТ, АсАТ, гаммаглутамилтрансферазы (ГГТ), щелочной фосфатазы (ЩФ), содержание общего белка, альбумина, общего и свободного билирубина. Результаты. Статистически значимых изменений концентрации общего белка, альбумина, общего и свободного билирубина при введении VMA–13–06 и VMA–13–11 в сравнении с контрольной группой не было зарегистрировано. Соединение VMA–13–12 способствовало повышению уровня общего и свободного билирубина на 43 % (p &lt; 0,01) и 90 % (p &lt; 0,01), при этом увеличение концентрации общего белка и альбумина не имело статистической значимости. Анализ энзимных показателей также свидетельствует об отсутствии поражения гепатоцитов при введении VMA–13–06 и VMA–13–11: активность АлАТ, АсАТ, ГГТ и ЩФ практически не изменялась. Введение VMA–13–12 привело к увеличению активности ферментов в сравнении с контрольными значениями: АлАТ – на 59 % (p &lt; 0,01), АсАТ – на 28 % (p &lt; 0,05), ГГТ – на 46 % (p &lt; 0,01), ЩФ – на 31 % (p &lt; 0,05). Заключение. Установлено отсутствие у пиримидиновых производных 3-[2-(1-нафтил)-2-оксоэтил]-6бромхиназолин-4(3Н)-он и 3-(2-трет-бутил-2-оксоэтил)хиназолин-4(3Н)-он гепатотоксических свойств. Соединение 3-(2-изопропилокси-2-оксоэтил)хиназолин-4(3Н)-он обладает гепатотоксичностью, способствуя снижению белоксинтезирующей и детоксицирующей функции печени.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to evaluate the hepatotoxic properties of new pyrimidine derivatives 3-[2-(1-naphthyl)-2- oxoethyl]-6-bromoquinazoline-4(3H)-oh (VMA–13–06), 3-(2-tert-butyl-2-oxoethyl)quinazoline-4(3H)-one (VMA-13- 11) and 3-(2-isopropyloxy-2-oxoethyl)quinazoline-4(3H)-oh (VMA-13-12). Material and methods. The study was carried out on male rats, which were divided into four groups: control receiving an intragastrically distilled water and experimental groups of animals receiving intragastrically suspended in distilled water pyrimidine compounds VMA- 13-06, VMA-13-11 and VMA-13-12 at doses of 1/10 of the molecular weight (39, 24 and 24 mg/kg respectively) for 60 days. In order to assess possible toxic damage to the liver, blood biochemical parameters were evaluated: alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase, alkaline phosphatase activity, total protein, albumin, total and free bilirubin content. Results. There were no statistically significant changes in total protein, albumin, total and free bilirubin after administration of VMA–13–06 and VMA–13–11 in comparison with the control group. The VMA–13–12 compound contributed to an increase in total and free bilirubin content by 43 % (p &lt; 0.01) and 90 % (p &lt; 0.01), while the increase in the concentration of total protein and albumin did not have any statistical significance. The analysis of enzyme parameters also indicates the absence of hepatocyte damage with the introduction of VMA- 13-06 and VMA-13-11: alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase, alkaline phosphatase activity did not change. VMA–13–12 administration led to an increase in enzyme activity in comparison with the control: alanine aminotransferase – by 59 % (p &lt; 0.01), aspartate aminotransferase – by 28 % (p &lt; 0.05), gamma- glutamyltransferase – by 46 % (p &lt; 0.01), alkaline phosphatase – by 31 % (p &lt; 0.05). Conclusions. We established the absence of hepatotoxic properties of pyrimidine derivatives 3-[2-(1-naphthyl)-2-oxoethyl]-6-bromoquinazoline-4(3H)- oh and 3-(2-tert-butyl-2-oxoethyl)quinazoline-4(3H)-oh. Compound 3-(2-isopropyloxy-2-oxoethyl)quinazoline-4(3H)- oh has a hepatotoxic effect, accompanied by a decrease in protein-synthesizing and detoxifying liver function.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>производные пиримидина</kwd><kwd>токсичность</kwd><kwd>гепатотоксичность</kwd><kwd>биохимические показатели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pyrimidine derivatives</kwd><kwd>toxicity</kwd><kwd>hepatotoxicity</kwd><kwd>biochemical parameters.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Jackson N., Czaplewski L., Piddock L.J.V.
