Popis: Species of the genusLacistemaare traditionally used by Brazilian and Peruvian indigenous communities. The present study investigated thein vitroantileishmanial activity against severalLeishmaniaspecies, cytotoxicity in murine peritoneal macrophages, antiproliferative activity against HL60 and Jurkat cells, and antibacterial activities against seven bacteria strains of the aerial parts of the methanolic crude extract and fractions ofLacistema pubescens. In addition, their chemical profile was also evaluated. Hexane fraction showed the most significant IC50values against all promastigotes ofLeishmaniaspecies tested, except forL. chagasi(IC50= 4.2 µg/mL forL. majorand IC50= 3.5 µg/mL forL. amazonensis). This fraction also exhibited a strong activity against amastigotes ofL. amazonensis(IC50= 6.9 µg/mL). The antiproliferative activity was also observed for methanolic extract and hexane fraction with IC50= 47.2 µg/mL and IC50= 39.7 µg/mL for HL60, respectively. Regarding the antimicrobial activity, the overall antibacterial activity was not very significative. Phytol and sitosterol were identified in the methanolic extract. Additionally, previous studies also revealed the presence of those compounds in the hexane fraction. Among other compounds, phytol and sitosterol were probably involved in the antileishmanial and cytotoxicity activities observed in this study.
