Abstract

There is an increasing need for substances with antiviral activity since the treatment of viral infections with most antivirals is often unsatisfactory due to the problem of, amongst other things, viral latency and the likelihood of new viral agents arising. Previously we isolated bauer-7-en-3b-yl acetate (BA), a pentacyclic triterpenoid obtained from the chloroform extract of an sample of propolis from southeast Brazil (TEIXEIRA, et al., 2006). Here we investigated the antiviral activity of BA against the alphaherpesviruses bovine herpesvirus 1 (BoHV-1) and pseudorabiesvirus (SuHV-1, suid herpesvirus) during infection of Madin-Darby bovine kidney (MDBK) and African green monkey kidney (VERO) cells cultures, respectively. In short, BA was tested for its cytotoxic properties and antiviral effect through virus yield reduction and virucidal activity in both cells. Results showed that BA 20µg mL-1 and 15µg mL-1 were the maximal non-cytotoxic concentration (MNCC) to VERO and MDBK cells, respectively. BA reduced significantly SuHV-1 titrers in both antiviral tests (p<0.05) while inhibition was not observed against BoHV-1. However, how BA interferes on the virus multiplication still need to be elucidated.
