Anti-Leishmania amazonensis activity of Serjania lethalis A. St.-Hil

Parasitology International, 2017
Extracts of Serjania lethalis A. St.-Hil leaves and stems were tested in order to identify potential agents against Leishmania amazonensis. The hexane fraction (HF) and dichloromethane subfractions (DDF and MDF) showed leishmanicidal effect. The anti-promastigote IC50 values were 10.29 (HF), 11.41 (DDF) and 28.33μg⁄mL (MDF); whereas those against ...
