Piper glabratum and P. acutifolium were analyzed for their content of main secondary constituents, affording nine new benzoic acid derivatives (1, 2, 4, 5, 7, and 10-13), in addition to four known compounds (3, 6, 8, and 9). Their structures were elucidated on the basis of spectroscopic data. Riguera ester reactions and optical rotation measurements established the new compounds as racemates. In the search for antiparasitic agents, the compounds were evaluated in vitro against the promastigote… CONTINUE READING
