Imiquimod is an imidazole derivative acting as an immunomodulator on the level of innate and adaptive immune system. Our objective was to evaluate the antiviral activity of generically reproduced imiquimod administered subcutaneously in mice and intravaginally in guinea pigs against herpes simplex virus (HSV), as well as to study the dynamics of serum interferon (IFN) synthesis under different dosing regimens. Results. When administered subcutaneously at doses of 0.5, 1.0 and 10 mg/kg imiquimod increased IFN production in mice in a dose-dependent manner with maximum serum IFN concentrations occurring 4 hours after dosing. Imiquimod protected mice from intraperitoneal HSV infection at doses of 3.2 and 32 LD50.The utmost protection (100% survival) was observed when imiquimod was administered at a dose of 100 mg/kg daily for 5 days before infection. Topical application of imiquimod 5% cream exhibited significantly more rapid and complete virus elimination in guinea pigs intravaginally infected with HSV type 2 compared to control group. Conclusion. Imiquimod produced as a generic possesses the same immunomodulatory and antiviral properties as the originally synthesized substance.</p></abstract><trans-abstract xml:lang="ru"><p>Производное имидазола - имихимод - относится к иммуномодуляторам, действующим на врожденную и адаптивную системы иммунитета. Целью исследований было изучение динамики синтеза сывороточного интерферона (ИФН) при разных режимах дозирования и оценка противовирусной активности воспроизведенного в России препарата имихимода в отношении вируса простого герпеса (ВПГ) при его подкожном применении мышам и интравагинальном - морским свинкам. Результаты. При подкожном введении имихимода мышам в дозах 0,5; 1 и 10 мг/кг наблюдали дозозависимое увеличение выработки ИФН, пик концентрации которых достигался через 4 ч после введения. Применение имихимода защищало лабораторных животных (мышей) от внутрибрюшинного заражения ВПГ в дозах 3,2 и 32 ЛД50. При этом максимальный защитный эффект (100% выживаемость) достигался при введении имихимода в дозе 100 мкг/кг ежедневно в течение 5 дней до заражения. Топическое применение имихимода в виде 5% крема по сравнению с контрольной группой сопровождалось достоверно более быстрой и полной элиминацией вируса при интравагинальном заражении морских свинок ВПГ 2-го типа. Заключение. Воспроизведенный аналог имихимода обладает иммуномодулирующими и противовирусными свойствами, выявленными у первоначально синтезированного химического соединения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>imiquimod</kwd><kwd>herpes simplex virus</kwd><kwd>guinea pigs</kwd><kwd>mice</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>имихимод</kwd><kwd>вирус простого герпеса</kwd><kwd>морские свинки</kwd><kwd>мыши</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Лебедев К.А., Понякина И.Д.
