This study analyzes the antileishmanial activity of the crude ethanol extract, fractions, and isolated compounds of A. othonianum nuts. Antileishmanial activity was evaluated against Leishmania amazonensis promastigotes in vitro. The phytochemical study was performed by high-performance liquid chromatography-high-resolution mass spectrometry-diode array detector (HPLC-HRMS-DAD) and by preparative HPLC. HPLC-HRMS-DAD analysis of the bioactive extract confirmed the presence of ten alkyl phenol derivatives that had previously been isolated from A. occidentale. Bioassay-guided isolation afforded cardanol triene, cardanol diene, cardanol monoene, cardol triene, anacardic acid triene, anacardic acid diene, and anacardic acid monoene. Cardol triene gave an IC50 of 80.66 µM. The obtained data suggest that the evaluated extract, fractions, and cardol triene had moderate activity against L. amazonensis promastigotes. This is the first description of alkyl phenols in A. othonianum.

Antileishmanial Activities

Leishmaniasis are a neglected tropical diseases that affecting 98 countries on three continents. Every year, 1.3 million of people are infected with the disease and 50.000 persons die because of this. The aim of this work was to evaluate antileishmanial activities in vitro from native species of South of Brazil belonging to the Myrtaceae family. The essential oils from leaves of Calyptranthes grandifolia, Calyptranthes tricona, Eugenia anomala, Eugenia arenosa, Eugenia pyriformis, Myrrhinium atropurpureum and Psidium salutare were analyzed in vitro for antileishmanial activity against promastigotes of Leishmania amazonensis, employed MTT assay. The essential oils from leaves of C. grandifolia, C. tricona, E. arenosa and E. pyriformis presented IC50 values of 31.27 ± 6.40 µg/mL, 26.13 ± 8.60 µg/mL, 13.72 ± 8.65 µg/mL and 19.73 ± 5.40 µg/mL, respectively, and not are statistically different from pentamidine (IC50 = 23.22 ± 9.04 µg/mL), the reference drug. The results show the potential of essential oils from leaves of C. grandifolia, C. tricona, E. arenosa and E. pyriformis as antileishmanial, as well as the importance of continuing studies to in order to advance in the search and development of new therapeutic options from of brazilian flora sources.

ABSTRACT The inhibition of intracellular Leishmania amazonensisgrowth by 2′,6′-dihydroxy-4′-methoxychalcone (DMC) isolated fromPiper aduncum was further enhanced after encapsulation of DMC in polymeric nanoparticles. Encapsulated DMC also showed increased antileishmanial activity in infected BALB/c mice, as evidenced by significantly smaller lesions and fewer parasites in the lesions.

Antileishmanial Activities

Leishmaniasis is a neglected tropical disease caused by members of the Leishmania genus of parasitic protozoa that cause different clinical manifestations of the disease. Current treatment options for the cutaneous disease are limited due to severe side effects, poor efficacy, limited availability or accessibility, and developing resistance. Essential oils may provide low cost and readily available treatment options for leishmaniasis. In-vitro screening of a collection of 52 commercially available essential oils has been carried out against promastigotes of Leishmania amazonensis. In addition, cytotoxicity has been determined for the essential oils against mouse peritoneal macrophages in order to determine selectivity. Promising essential oils were further screened against intracellular L. amazonensis amastigotes. Three essential oils showed notable antileishmanial activities: frankincense (Boswellia spp.), coriander (Coriandrum sativum L.), and wintergreen (Gualtheria fragrantissima Wall.) with IC50 values against the amastigotes of 22.1 ± 4.2, 19.1 ± 0.7, and 22.2 ± 3.5 μg/mL and a selectivity of 2, 7, and 6, respectively. These essential oils could be explored as topical treatment options for cutaneous leishmaniasis.

Based on the ethnopharmacological evidences about the antileishmanial activity ofCopaiferaspp. oleoresins, the effects of crude extracts and fractions of oleoresin of two specimens fromCopaifera pauperawere evaluated onLeishmania amazonensisandLeishmania infantumstrains. The oleoresin rich inα-copaene (38.8%) exhibited the best activity againstL. amazonensis(IC50= 62.5 μg/mL) and againstL. infantum(IC50= 65.9 μg/mL). The sesquiterpeneα-copaene isolated was tested alone and exhibited high antileishmanial activityin vitrowith IC50values forL. amazonensisandL. infantumof 17.2 and 11.4 μg/mL, respectively. In order to increase antileishmanial activity, nanoemulsions containing copaiba oleoresin andα-copaene were developed and assayed againstL. amazonensisandL. infantumpromastigotes. The nanoemulsion containingα-copaene (NANOCOPAEN) showed the best activity against both species, with IC50of 2.5 and 2.2 μg/mL, respectively. This is the first report about the antileishmanial activity ofα-copaene.
