Caldensinic acid, a prenylated benzoic acid from Piper caldense
(ELSEVIER SCIENCE BV, 2009)
The CH(2)Cl(2) and MeOH extracts from leaves of Piper caldense were subjected to chromatographic separation procedures to afford the new prenylated benzoic acid, caldensinic acid (3-[(2`E,6`E,10`E)-11`-carboxy-3`,7`,15`- ...
In vitro activity of compounds isolated from Piper crassinervium against Trypanosoma cruzi
(Taylor & Francis Ltd, 2008-01-01)
This study describes the antichagasic potential of five compounds isolated from leaves of Piper crassinervium (Piperaceae). Two prenylated benzoic acid derivatives, one prenylated hydroquinone and two flavanones, were ...
