Anti-HIV activity of the molecular complex forming during interaction
between yeast RNA and tilorone was studied in vitro on the models of a
cute and chronic infection. Addition of this agent to the cells infect
ed with HIV-1/IIIB and HIV-1/BRU decreased the virus reproduction cont
rolled by assessing the viability of cells, syncytium production, and
accumulation of p24 antigen in culture medium. The authors hypothesize
that the detected anti-HIV effect is due to its capacity to produce t
ype I interferon and direct antiviral action.
