Easily pass through biological membranes soapy amphiphilic inducer of interferon γ – the promising drug for treatment of human hepatitis C

The interferon inducing activity of a soapy amphiphilic complex of a high-polymeric single-stranded RNA from Saccharomyces cerevisiae, containing short double-stranded regions with oleic acid has been studied (the Vitalang-2 drug). It was discovered that the complex is capable of crossing the biological membranes and it induces biosynthesis of IFN-γ in the animal models in a dose-dependent manner. The antiviral activity of the Vitalang-2 against human hepatitis C on the model of bovine viral diarrhea-mucosal disease in cattle (BVD-MD) is investigated. It was found that the maximum tolerated drug in a dose of 5 mg/cm³ has a profound inhibitory effect on BVD-MD virus, in cultured coronary calf cell lines; virus reduction rate was 1.97 lg10TTsD50/cm³. Therefore the study demonstrated that Vitalang-2 has antiviral activity against a BVD-MD virus in cattle, and thus it can be expected that this drug will be effective against hepatitis C in human patients.
