Japanese encephalitis virus (JEV) and Akabane virus (AKAV) are mosquito-borne viruses that cause encephalitis and reproductive disorders in horses and cattle, respectively. There is no treatment for JEV or AKAV infections in animals. Therefore, we evaluated the antiviral activity of 18-mer amphipathic peptides in the 1b-4/21-C series on JEV and AKAV using Vero cells in vitro and evaluated their effects on JEV in mice. Of 6 peptides, 1b-4/21-C12 had the lowest IC<SUB>50</SUB> of 0.313 against JEV and its use as an antiviral against JEV and AKAV was examined. The IC<SUB>50 </SUB>of 1b-4/21-C12 against JEV and AKAV was 0.78 and 1.14 μM, respectively. Mice treated with 5 or 2 mg/kg of 1b-4/21-C12 had 32% and 16% survival rates, respectively, and the surviving mice treated with 1b-4/21-C12 began to gain weight beginning 8 days post challenge with the virulent Nakayama strain. Moreover, 20 μM 1b-4/21-C peptide had no cytotoxic effects on Vero cells. Our in vitro and in vivo results indicate that 1b-4/21-C12 has antiviral activity against enveloped JEV and AKAV and might be useful as a therapeutic substance.
