Um novo sesquiterpeno, aromadendrano-4β,10α,15-triol, foi isolado das folhas de Xylopia brasiliensis Spreng (Annonaceae), juntamente com quatro derivados de esqueleto aromadendrano e três esteróides. As estruturas dos metabólitos foram definidas por meio da análise dos respectivos espectros de RMN, incluindo experimentos bidimensionais, além de espectrometria de massas. Os sesquiterpenos aromadendranos diidroxilados apresentaram atividade antifúngica frente a Cladosporium cladosporioides.A new sesquiterpenoid, aromadendrane-4β,10α,15-triol, was isolated from the leaves of Xylopia brasiliensis Spreng (Annonaceae), together with four known aromadendrane derivatives and three steroids. The structures of these compounds were defined by analysis of their NMR spectral data, including bidimensional analysis, and mass spectrometry. The isolated aromadendranediol derivatives showed antifungal activity against Cladosporium cladosporioides.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
