Actividad contra Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) de extractos metanólicos de plantas de uso medicinal en México

Abstract: Activity against Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) of methanolic extracts of medicinal use plants in Mexico. American trypanosomiasis is a potentially lethal disease caused by the hemoflagellate protozoan Trypanosoma cruzi. This neglected disease affects from 6 to 7 million people worldwide. Currently there are only two medicines to treat this disease: beznidazol and nifurtimox, both effective if they are administrated in the acute phase of infection, although their effectiveness fades away … Show more

“…Regarding the toxicity model with A. salina described in this study, this has been widely used in toxicology to evaluate the risks of using various substances, including plant extracts, as it is an easy and economical technique that can also provide guidance on the toxicity of many natural compounds, drugs, and extracts [46,85]. A prior investigation assessing the MeOH extract of Chelidonium majus (Papaveraceae) revealed significant activity on A. salina larvae and colon carcinoma cells (HT-29), highlighting the concentrated cytotoxicity within the basic extract.…”

“…Prior to the assay, the artificial seawater was conditioned by supplying air with an aquarium pump for 24 h. For the hatching of A. salina nauplii, a rectangular glass container (17 × 14 × 7 cm) was adapted, with a dark section where the cysts were incubated and an illuminated area that allows only hatched nauplii to be obtained by means of phototropism. After an incubation period of 48 h under room temperature conditions of 25 ± 2.0 • C (aeration and constant light), the test was carried out using 96-well transparent plastic microplates with a concave bottom (Corning ® ), in which 20 nauplii and different concentrations of the treatments (10, 100, 200, 400, 600, 800, 1000, and 2000 µg/mL) were deposited in a final volume of 200 µL per well [46]. After 24 h of exposure, the count of live and dead A. salina nauplii was recorded to determine the IC 50 values.…”

“…Diversos ensayos in vitro para evaluar la actividad tripanocida, han sido realizados con extractos y/o derivados de plantas medicinales; tal es el caso de Rojas et al (2010), donde evaluaron aceites esenciales extraídos de 10 especies de plantas, contra el estadio de epimastigote de T. cruzi, destacando una IC 50 de 63.09 μg/ml para Cimbopogon citratus y 96.49 μg/ml para Aloysia triphylla, su actividad biológica podría estar relacionada a su componente principal, que es el citral, el cual posee propiedades antibacterianas y antiparasitarias. En el caso de plantas mexicanas, Pérez-Treviño et al (2017), evaluaron extractos metanólicos de Hematoxilum brasiletto, Marrubium vulgare, Schinus molle y Cympongon citratusk, obteniendo CI 50 de 543 μg/ml, 647 μg/ml, 827 μg/ml y 1 210 μg/ ml, respectivamente, en contra del estadio de epimastigote de una cepa de T. cruzi obtenida en Cerralvo, Nuevo León.…”

“…Por otro lado, la especie M. púdica presenta actividad antibacteriana, pero destaca su actividad antipaludica frente Plasmodium berghei; estas actividades se atribuyen principalmente a la presencia de terpenoides, flavonoides y alcaloides (Blanco, 2019). En el caso de M. malacophylla, su actividad tripanocida presentó una CI 50 > 950 ppm en los extractos evaluados; estos son superiores o similares a las demás especies analizadas en el presente estudio, e incluso a extractos de otras especies (Pérez-Treviño et al, 2017).…”
