Дипептидный лиганд транслокаторного белка гд-23 проявляет анксиолитическую и ноотропную активности

Abstract

TSPO белок-переносчик холестерина в митохондриальный матрикс (транслокаторный белок), участвует в биосинтезе нейростероидов. В НИИ фармакологии им. В.В. Закусова сконструирован топологический аналог лиганда TSPO Алпидема дипептид ГД-23 (амид N-карбобензокси-L-триптофанил-L-изолейцина). Установлено, что ГД-23 в дозах 0.05-0.5 мг/кг (в/б) проявляет анксиолитическую активность в приподнятом крестообразном лабиринте и ноотропную активность в тесте распознавания нового объекта в условиях скополаминовой амнезии у грызунов. Показано, что ГД-23 не влияет на спонтанную двигательную активность, что исключает его седативное действие. Анксиолитическая и ноотропная активности ГД-23 блокируются антагонистом TSPO PK11195, что подтверждает участие TSPO в фармакологических эффектах дипептида.
