SANCHEZ-SUAREZ, Jeysson et al. Evaluation of the cytotoxic and leishmanicidal activity of extracts and fractions of Piper cumanense and Piper holtonii. Rev. colomb. cienc. quim. farm. [online]. 2010, vol.39, n.1, pp.21-29. ISSN 0034-7418.

Piper genusá species are reported as promissory as tropical diseases treatment. This research showed the cytotoxic and leishmanicidal activity of extracts and fractions of different polarity derived from Piper cumanense (P. cumanense) and Piper holtonii (P. holtoni) on murine macrophages J774 and L. panamensis promastigotes (MHOM/ CO/87/UA140). Hexanic fraction (PcH) exhibited leishmanicidal effect with 2-fold index selectivity in this in vitro model used. These results suggest a potential antileishmanial activity which should be more studied.
