The antiretroviral properties of Fullevir (sodium salt of fullerenepolyhydropolyaminocaproic acid) manufactured by IntelFarm Co.) were studied in the human cell culture infected with human immunodeficiency virus (HIV). The agent was ascertained to be able to protect the cell from the cytopathic action of HIV. The 90% effective concentration (EF90) was 5 microg/ml. The 50% average toxic concentration was 400 microg/ml. Testing of different (preventive and therapeutic) Fullevir dosage regimens has shown that the drug is effective when used both an hour before and an hour after infection and when administered simultaneously with cell infection. The longer contact time for the agent with the cells increased the degree of antiviral defense. Co-administration of Fullevir and the HIV reverse transcriptase inhibitor Retrovir (azidothymidine) showed a synergistic antiretroviral effect. Thus, Fullevir may be regarded as a new promising antiretroviral drug for the treatment of HIV infection.

The antiherpetic properties of a fullerene derivative with aminocaproic acid (manufactured by Intelfarm Co. as Fullevir) were studied in in vitro (in sensitive cell cultures) and in vivo (on a murine model of experimental herpetic encephalitis) experiments. Fullevir was found to protect tissue culture cells from the cytodestructive action of herpes simplex virus type 1. It was estimated that ED50 = 5.3 microg/ml and ED90 = 29.1 microg/ml. The agent was most effective when it was administered before and 30 minutes after cell culture infection. The in vivo study established that Fullevir showed a significant protective effect in experimental herpetic encephalitis. The protection rates were 29.8% and 41.0% with the total doses of Fullevir of 500 mg/kg (p < 0.007) and 1000 mg/kg (p < 0.004), respectively. Thus, the in vitro and in vivo studies demonstrated the antiherpetic effect of a fullerene-aminocaproic acid complex (1-hydrofullereneaminocaproic acid, sodium salt) having the trade name Fullevir.
