摘要：

Based on the ethnopharmacological evidences about the antileishmanial activity of Copaifera spp. oleoresins, the effects of crude extracts and fractions of oleoresin of two specimens from Copaifera paupera were evaluated on Leishmania amazonensis and Leishmania infantum strains. The oleoresin rich in alpha-copaene (38.8%) exhibited the best activity against L. amazonensis (IC50 = 62.5 mu g/mL) and against L. infantum (IC50 = 65.9 mu g/mL). The sesquiterpene alpha-copaene isolated was tested alone and exhibited high antileishmanial activity in vitro with IC50 values for L. amazonensis and L. infantum of 17.2 and 11.4 mu g/mL, respectively. In order to increase antileishmanial activity, nanoemulsions containing copaiba oleoresin and alpha-copaene were developed and assayed against L. amazonensis and L. infantum promastigotes. The nanoemulsion containing alpha-copaene (NANOCOPAEN) showed the best activity against both species, with IC50 of 2.5 and 2.2 mu g/mL, respectively. This is the first report about the antileishmanial activity of alpha-copaene.
