JO - Phytochemistry Letters SP - 162 EP - 164 VL - 5 IS - 1 KW - Malaria KW - P. falciparum KW - Quassia amara KW - Quassinoids KW - Simaroubaceae N2 - A new quassinoid Picrasin K 1 was isolated from a decoction made of Quassia amara leaves, traditionally used in French Guyana to treat malaria. The structure and relative stereochemistry of 1 was determined through extensive NMR analysis. Picrasin K showed a low activity against Plasmodium falciparum in vitro (IC 50 = 8 μM), and a similar low activity on human cancerous cells line (IC 50 = 7 μM on MCF-7 cells line). © 2011 Phytochemical Society of Europe.
