Cytotoxic and Anti-inflammatory Cembranoids from the Soft Coral Lobophytum crassum
Abstract
Five new cembranoids, namely, crassumolides A and B and D-F (1 and 2 and 4-6), along with four known metabolites, 7-10, were isolated from the soft coral Lobophytum crassum. Crassumolide C (3) was isolated for the first time from a natural source. The structures of these compounds were elucidated by extensive spectroscopic analysis and comparison of the NMR data with those of known analogues. The absolute stereochemistry of 1 was determined using the modified Mosher's method. Chemical transformation of 7 into the corresponding methyl ester 3 revealed the absolute stereochemistry of 3. Compounds 1, 3, and 7 were cytotoxic toward Ca9-22 cancer cells, and 10 was broadly cytotoxic toward all six test cancer cell lines used. Compounds 1, 3, 7, and 10 were found to inhibit the accumulation of the pro-inflammatory proteins iNOS and COX-2 at 10 μM.

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.
