Antiplasmodial and antileishmanial activities of compounds from Piper tuberculatum Jacq fruits

Abstract INTRODUCTION This study assessed the activity of compounds from Piper tuberculatum against Plasmodium falciparum and Leishmania guyanensis. METHODS The effects of compounds from P. tuberculatum fruits on P. falciparum and L. guyanensis promastigote growth in vitro were determined. Hemolytic action and cytotoxicity in HepG2 and J774 cells were measured. RESULTS Three compounds showed strong antiplasmodial activity and one compound showed strong antileishmanial activity. Two compounds were non-toxic to HepG2 cells and all were toxic to J774 cells. The compounds showed no hemolyti...
