Laurentixanthone C: A New Antifungal and Algicidal Xanthone from Stem Bark of Vismia laurentii

Laurentixanthone C (1), a new xanthone, was isolated from the stem bark of Vismia laurentii (Guttiferae or Clusiaceae), in addition to the known compounds vismiaquinone (2), bisvismiaquinone (3), and dammaradienol (4). The structures were established based on spectroscopic studies, notably of the 2D...

Zusammenfassung:Laurentixanthone C (1), a new xanthone, was isolated from the stem bark of Vismia laurentii (Guttiferae or Clusiaceae), in addition to the known compounds vismiaquinone (2), bisvismiaquinone (3), and dammaradienol (4). The structures were established based on spectroscopic studies, notably of the 2D NMR spectra. Preliminary results showed that 1 is algicidal and strongly antibacterial against the Gram-positive bacteria Bacillus megaterium and Chlorella fusca, respectively.
