В работе исследованы иммунотропные свойства новых производных аденина, синтезированных в Волгоградском научном центре РАМН. Установлено, что вещества VMA-03-01, VMA-01-21, VMA-99-56 обладают стимулирующим влиянием на функции фагоцитов; усиливают либо ослабляют в зависимости от концентрации экспрессию CD6 9 и CD25 на активированных лимфоцитах, то есть влияют как на раннюю, так и на позднюю фазы активации лимфоцитов. В экспериментах in vivo показано, что вещества VMA-03-01 и VMA-01-21 способны ингибировать продукцию специфических антител.
Five compounds (VMA-03-01, VMA-01-21, VMA-99-56, VMA-99-82, VMA-00-29) were evaluated for their in vitro and in vivo immune-modulating effects. VMA-03-01, VMA-01-21, VMA-99-56 have been shown to increase phagocytosis and microbicidal activity in human neutrophils, thus affecting innate immunity. All compounds affect early and late stages of T cell activation, which is shown by measurement of CD69+ and CD25+ T cells. In the rat model, compounds VMA-03-01 and VMA-01-21 inhibit specific antibody production.
