Nitrogen-Containing Dimeric nor-Multiflorane Triterpene from a Turraea sp.
Abstract
The new triterpene turranoic acid (1) and thenew N-containing nor-triterpene turraenine (2), along with triptocallic acid B (3) and esculentoic acid (4) were isolated from leaves of a Turraea sp. Compounds 1-3 showed weak to moderate in vitro antiplasmodial activity against the chloroquine-resistant Plasmodium falciparum strain FCM29. Compound 1 also displayed weak cytotoxic activity against the non-small lung cancer cell line H522-T1 with an IC50 value of 16.4 μM.
