[Study of the anti-HIV activity of miramistin].

The anti-HIV activity of a cationic detergent myramistin and nonionic detergent dezintegron-0 (d-0) was studied using HIV-1 strains III B/H9 and BRU in lymphoblastoid cells MT-4 and Jurkat-tat. Myramistin in a concentration of 0.075 mg/ml was shown to prevent HIV-1 replication in MT-4 when these cells were cocultivated with the cells preinfected and treated with the detergent. Myramistin in concentrations from 0.030 to 0.050 mg/ml delayed the accumulation of virus antigens in the cells by 4 and 14 days, respectively, without preventing the infection of intact cells. Nonionic d-0 prevented HIV-1 infection of intact Jurkat-tat cells at a concentration of 12.5 mg/ml.
