In vitro effect of Aloe vera, Coriandrum sativum and Ricinus communis fractions on Leishmania infantum and on murine monocytic cells
In South America, visceral leishmaniasis is a zoonosis caused by the protozoan species Leishmania infantum (syn. L. chagasi) and is primarily transmitted through the bite of the female Lutzomyia longipalpis. Its main reservoir in urban areas is the dog. The application of control measures recommende...

description | In South America, visceral leishmaniasis is a zoonosis caused by the protozoan species
Leishmania infantum (syn.
L. chagasi) and is primarily transmitted through the bite of the female
Lutzomyia longipalpis. Its main reservoir in urban areas is the dog. The application of control measures recommended by health agencies have not achieved significant results in reducing the incidence of human cases, and the lack of effective drugs to treat dogs resulted in the prohibition of this course of action in Brazil. Therefore, it is necessary to search new alternatives for the treatment of canine and human visceral leishmaniasis. The objectives of this study were to evaluate the
in vitro effect of fractions from
Aloe vera (aloe),
Coriandrum sativum (coriander), and
Ricinus communis (castor) on promastigotes and amastigotes of
L. infantum and to analyze the toxicity against the murine monocytic cells RAW 264.7. To determine the viability of these substances on 50% parasites (IC50), we used a tetrazolium dye (MTT) colorimetric assay (bromide 3-4.5-dimethylthiazol-2-yl-2,5-dephenyltetrazolium), and on amastigotes we performed an
in situ ELISA. All fractions were effective against
L. infantum promastigotes and did not differ from the positive control pentamidine (
p
>
0.05). However, the
R. communis ethyl acetate and chloroform fractions, as well as the
C. sativum methanol fraction, were the most effective against amastigotes and did not differ from the positive control amphotericin B (
p
>
0.05). The
R. communis ethyl acetate fraction was the least toxic, presenting 83.5% viability of RAW 264.7 cells, which was similar to the results obtained with amphotericin B (
p
>
0.05). Based on these results, we intend to undertake
in vivo studies with
R. communis ethyl acetate fractions due the high effectiveness against amastigotes and promastigotes of
L. infantum and the low cytotoxicity towards murine monocytic cells. |
