Introduction: Medicinal plants play an important role between different biological processes as antitumor, cytotoxicity, antimicrobial, anti-inflammatory, anti-estrogen, anti-allergic, antioxidant, among other. Colombia has about 10% of all plant species in the world, being the North coast with highest medicinal herbs few studied. This study aims to evaluate in vitro cytotoxic activity on human promonocytic cell line U937 and leishmanicidal activity against intracellular amastigotes of Leishmania (V) panamensis (MHOM/CO/87/UA140-EpiR-GFP strain) of fractions obtained from leaves Heliotropium indicum Linn and Cordia dentata Poir. Material and Methods: The plants were collected in 2013 at the North of Bolivar (Colombia). The cytotoxic activity was performed using 2,5-diphenyl-tetrazolium enzymatic method 3-[4,5-dimethylthiazol-2-yl] (MTT) and antileishmanial assessment by ﬂow cytometric technique. The assays were done by triplicate in at least two independent experiments, as positive control was used amphotericin B. Results were expressed as fifty cytotoxic concentrations (CC50), concentration necessary to kill 50% of cells, and fifty effective concentrations (EC50) calculated by Probit analysis (Parametric method of linear regression that permits doses-response analysis); it was similarly determined the Selectivity Index (SI). Results: H. indicum (Hi) fractions were more cytotoxic than C. dentata (Cd) against cell line U937. Hi-I- 18B and Hi-I-18E fractions were considered as potentially cytotoxic (CC50 11.7 and 13.9 mg/mL). Moreover, the Cd-I-13C fraction was midly cytotoxic (CC50 139.1 µg/mL). The fractions were first screened for antileishmanial activity against Leishmania (V) panamensis at 13. 5 ± 0.3 mg/mL, IS = 0.9 (Hi-I- 18B) and 11.5 ± 2.6 mg/mL, IS = 1.2 (Hi-I-18E) showed % growth inhibition were 18.5 and 21.8%. Cd-I-13C at 24.5 mg/mL, IS = 5.7, growth inhibition was 54.3%. Conclusions: This suggests that plants species are rich potential source of molecules useful for treatment of cancer and parasitic diseases.
