The resulting compound 1 is a yellow oil, soluble in chloroform, toluene, acetone, insoluble in water and hexane.
Пример 2. Для характеристики антибактериальной активности использовали стандартные параметры: минимальная подавляющая концентрация (МПК), которую определяли модифицированным методом двукратных серийных разведений (МУК 4.2.1890-04 Определение чувствительности микроорганизмов к антибактериальным препаратам) и минимальная бактерицидная концентрация (МБК) (Медицинские лабораторные технологии: Руководство по клинической лабораторной диагностике, п/р Каприщенко, 2013, Т.2, стр. 407). Тесты проводили с использованием культур модельных микроорганизмов Escherichia coli МС4100 и Staphylococcus epidermidis ATCC29887 на питательной среде Луриа-Бертани в 96-луночных полистироловых планшетах. Конечная концентрация микроорганизмов в лунках составляла 5*105 КОЕ/мл. Культивирование проводили при 37°С без перемешивания. Определение МПК и высевы для определения МБК производили через 24 ч. На первом этапе исследуемые соединения растворяли в диметилсульфоксиде (ДМСО), дальнейшие разведения производили в метаноле. В качестве начальных в тестах использовали концентрации, которые при внесении в питательную среду Луриа-Бертани не образовывали осадка (от 0,2 до 4 мг/мл). Example 2. To characterize the antibacterial activity, standard parameters were used: the minimum inhibitory concentration (MIC), which was determined by the modified method of two-fold serial dilutions (MUK 4.2.1890-04 Determination of the sensitivity of microorganisms to antibacterial drugs) and the minimum bactericidal concentration (MBC) (Medical laboratory technologies : Guidelines for clinical laboratory diagnostics, p / r Kaprischenko, 2013, V.2, p. 407). Tests were performed using cultures of model microorganisms Escherichia coli MC4100 and Staphylococcus epidermidis ATCC29887 on Luria-Bertani nutrient medium in 96-well polystyrene plates. The final concentration of microorganisms in the wells was 5*10 5 CFU/ml. Cultivation was carried out at 37°C without stirring. Determination of the MIC and seeding for the determination of MBC was carried out after 24 hours. At the first stage, the studied compounds were dissolved in dimethyl sulfoxide (DMSO), further dilutions were made in methanol. The initial concentrations used in the tests were concentrations that, when added to the Luria-Bertani nutrient medium, did not form a precipitate (from 0.2 to 4 mg/ml).
Пример 3. Острую токсичность (ЛД50, мг/мл) соединения 1 определяли по методу Г. Н. Першина [Першин Г. Н. Методы экспериментальной химиотерапии // М., С. 100, 109-117 (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 > 1500 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, 109-117 (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, the LD 50 is > 1500 mg/kg.
Согласно классификации токсичности препаратов, соединение 1 относится 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]. Результаты испытаний представлены в таблице:According to the toxicity classification 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]. The test results are presented in the table:
МИК*-минимальная ингибирующая концентрация,MIC*-minimum inhibitory concentration,
МБК**-минимальная бактерицидная концентрация.MBC**-minimum bactericidal concentration.
Как видно из таблицы, заявляемое соединение 1 превышает по антибактериальной активности препарат сравнения (Фенилсалицилат) в 15 раз по отношению к St. epidermidis. 1-(6-тозил-5,6,7,8-тетрагидро-2,6-нафтиридин-3-ил)этан-1-он 1 проявляет более высокую активность по сравнению с эталоном сравнения в отношении грамположительных микроорганизмов, что делает возможным его использование для создания новых лекарственных средств антибактериального действия.As can be seen from the table, the claimed compound 1 exceeds the reference drug (Phenyl salicylate) in antibacterial activity by 15 times in relation to St. epidermidis . 1-(6-tosyl-5,6,7,8-tetrahydro-2,6-naphthyridin-3-yl)ethan-1-one 1 exhibits higher activity against gram-positive microorganisms compared to the reference standard, which makes it possible its use for the creation of new antibacterial drugs.
