Пример 2. Определение антимикробной активности проводили методом двукратных серийных разведений [Першин Г.Н. «Методы экспериментальной химиотерапии, 1971, с. 109] на музейных тест - культурах: Staphylococcus aurous, штамм 906 (ФГБУ «Научный центр экспертизы средств медицинского применения», г. Москва). В опытах использовали 18 часовые агаровые тест -культуры (5*105 микробных тел в 1 мл среды). Для исследования брали растворы соединения 1 в диметилформамиде (ДМФА). Максимальная из испытанных концентраций была 1000 мкг/мл. Пробирки инкубировали при 37°С с последующим высевом через 20 часов и 7 суток в пробирки со скошенным мясопептонным агаром. Учет результатов проводили по наличию и характерному росту культур микроорганизмов на питательной среде.Example 2. Determination of antimicrobial activity was carried out by the method of two-fold serial dilutions [Pershin G.N. "Methods of experimental chemotherapy, 1971, p. 109] on museum test cultures: Staphylococcus aurous, strain 906 (FGBU "Scientific Center for Expertise of Medicinal Products", Moscow). In the experiments, 18 hour agar test cultures (5*10 5 microbial bodies in 1 ml of medium) were used. Solutions of compound 1 in dimethylformamide (DMF) were taken for the study. The maximum concentration tested was 1000 µg/ml. The tubes were incubated at 37°C, followed by inoculation after 20 hours and 7 days in tubes with beveled beef agar. The results were recorded according to the presence and characteristic growth of cultures of microorganisms on a nutrient medium.
Пример 3.Острую токсичность (ЛД50, мг/мл) соединения 1 определяли по методу Г. Н. Першина [Першин Г. Н. Методы экспериментальной химиотерапии // М., С. 100, 109-11.7 (1971.)]. Соединение 1 вводили внутрибрюшинно белым мышам массой 16-18 г в виде взвеси в 2%крахмальной слизи и наблюдали за поведением и гибелью животных в течение 10 суток. Для исследуемого соединения 1 ЛД50 составляет > 1000 мг/кг,Example 3. Acute toxicity (LD 50 , mg/ml) of compound 1 was determined by the method of G. N. Pershin [Pershin G. N. Methods of experimental chemotherapy // M., S. 100, 109-11.7 (1971.)]. Compound 1 was administered intraperitoneally to white mice weighing 16–18 g as a suspension in 2% starch mucus, and the behavior and death of the animals were observed for 10 days. For test compound 1, LD 50 is > 1000 mg/kg,
Согласно классификации токсичности препаратов, соединение 1 относятся к V классу практически нетоксичных препаратов [Измеров Н.Ф., Саноцкий И.В., Сидоров К.К. Параметры токсикометрии промышленных ядов при однократном воздействии: Справочник. М., 1977. - с. 196].According to the classification of the toxicity of drugs, compound 1 belongs to the V class of practically non-toxic drugs [Izmerov N.F., Sanotsky I.V., Sidorov K.K. Parameters of toxicometry of industrial poisons at a single exposure: a Handbook. M., 1977. - p. 196].
Противомикробная активность соединения 1.Antimicrobial activity of compound 1.
Как видно из таблицы, заявляемое соединение 1 превышает по противомикробной активности препарат сравнения (Фенилсалицилат) по отношению к St. aureus. Таким образом, этил-4-(4-гидрокси-2-оксо-4-(тиофен-ил)бут-3-ентиоамидо)бензоат 1 проявляет более высокую и активность, по сравнению с аналогом (2), что делает возможным использовать его для создания новых лекарственных средств против заболеваний, вызываемых золотистым стафилококком.As can be seen from the table, the claimed compound 1 exceeds the reference drug (Phenyl salicylate) in antimicrobial activity in relation to St. aureus. Thus, ethyl 4-(4-hydroxy-2-oxo-4-(thiophen-yl)but-3-entioamido)benzoate 1 exhibits higher activity and activity compared to analogue (2), which makes it possible to use it to create new drugs against diseases caused by Staphylococcus aureus.
