Scopularides A and B, Cyclodepsipeptides from a Marine Sponge-Derived Fungus, Scopulariopsis brevicaulis
Abstract
Two novel cyclodepsipeptides, scopularides A and B, were found in the fungus Scopulariopsis brevicaulis, which was isolated from the marine sponge Tethya aurantium. In addition, the known fungal metabolite paxilline was identified. The structures of the scopularides were elucidated by NMR, MS, and chemical derivatization methods as cyclo-(3-hydroxy-4-methyldecanoyl-Gly-L-Val-D-Leu-L-Ala-L-Phe) and cyclo-(3-hydroxy-4-methyloctanoyl-Gly-L-Val-D-Leu-L-Ala-L-Phe) for scopularide A and B, respectively. Antibiotic activity against Gram-negative bacteria was absent and against Gram-positive bacteria was weak, but activity against several tumor cell lines was significant at 10 microg/mL.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
