Three new cembranoids from the Taiwanese soft coral Sarcophyton ehrenbergi.

ABSTRACT: In order to search for new bioactive substances from marine organisms, we have investigated the acetone extracts of the soft coral Sarcophyton ehrenbergi collected at San-Hsian-Tai, Taitong County, Taiwan. Chromatographic fractionation of the extracts of the octocoral S. ehrenbergi led to the isolation of three new cembranoids, (+)-12-ethoxycarbonyl-11Z-sarcophine (1), ehrenbergol A and B (2 and 3). The structures of these isolated metabolites were elucidated through extensive spectroscopic analyses. Moreover, metabolites 1-3 were evaluated in vitro for their cytotoxicity towards selected cancer cell lines and antiviral activity against human cytomegalovirus (HCMV).

New Bicyclic Cembranoids from the South China Sea Soft Coral Sarcophyton trocheliophorum.

Project description:Nine new bicyclic cembranoids, sarcophytrols M-U(1-9), were isolated from the South China Sea soft coral Sarcophyton trocheliophorum as minor components, along with one known related cembranoid 10. Their structures were elucidated by detailed spectroscopic analysis and chemical conversion. The chemical structures of these metabolites are characterized by the different patterns of the additional cyclization within the 14-member skeleton, which leading to the formation of furan, pyran, oxepane, and peroxyl rings, respectively. Among them, sarcophytrols R and S(6 and 7) share a rare decaryiol skeleton with an unusual C12/C15 cyclization. In addition, the absolute configurations of sarcophytrols M and T(1 and 8) were determined by the modified Mosher's method. The research of these new secondary metabolites provided a further understanding of the diversity of cyclized cembranoids from the title species.

New Cembranoids and a Biscembranoid Peroxide from the Soft Coral Sarcophyton cherbonnieri.

Project description:Six new cembranoids, cherbonolides A-E (1⁻5) and bischerbolide peroxide (6), along with one known cembranoid, isosarcophine (7), were isolated from the Formosan soft coral Sarcophyton cherbonnieri. The structures of these compounds were elucidated by detailed spectroscopic analysis and chemical methods. Compound 6 was discovered to be the first example of a molecular skeleton formed from two cembranoids connected by a peroxide group. Compounds 1⁻7 were shown to have the ability of inhibiting the production of superoxide anions and elastase release in N-formyl-methionyl-leucyl-phenyl-alanine/cytochalasin B (fMLF/CB)-induced human neutrophils.

Polyoxygenated cembrane diterpenoids from the soft coral Sarcophyton ehrenbergi.

Project description:Five new polyoxygenated cembranoids, named (+)-1,15-epoxy-2-methoxy-12-methoxycarbonyl-11E-sarcophytoxide (1), (+)-2-epi-12-methoxycarbonyl-11E-sarcophine (2), 3,4-epoxyehrenberoxide A (3), ehrenbergol D (4) and ehrenbergol E (5), were obtained from the soft coral Sarcophyton ehrenbergi. The structures of 1-5 were established on the basis of comprehensive NMR and HR-ESI-MS analyses and by comparison with reported data in the literature. Compounds 4 and 5 showed moderate cytotoxicity against P-388 (mouse lymphocytic leukemia) cancer cell line with EC50 values of 2.0 and 3.0 μM, respectively. Compound 2 exhibited slight antiviral activity against HCMV (human cytomegalovirus) with IC50 values of 25.0 μg/mL.

Biscembranoids and Cembranoids from the Soft Coral Sarcophyton elegans.

Project description:Two novel biscembranoids, sarelengans A and B (1 and 2), five new cembranoids, sarelengans C-G (3-7), along with two known cembranoids (8 and 9) were isolated from the South China Sea soft coral Sarcophyton elegans. Their structures were determined by spectroscopic and chemical methods, and those of 1, 4, 5, and 6 were confirmed by single crystal X-ray diffraction. Compounds 1 and 2 represent the first example of biscembranoids featuring a trans-fused A/B-ring conjunction between the two cembranoid units. Their unique structures may shed light on an unusual biosynthetic pathway involving a cembranoid-∆⁸ rather than the normal cembranoid-∆¹ unit in the endo-Diels-Alder cycloaddition. Compounds 2 and 3 exhibited potential inhibitory effects on nitric oxide production in RAW 264.7 macrophages, with IC50 values being at 18.2 and 32.5 μM, respectively.

Anti-Inflammatory Cembranoids from a Formosa Soft Coral Sarcophyton cherbonnieri.

Project description:The present investigation on chemical constituents of the soft coral Sarcophyton cherbonnieri resulted in the isolation of seven new cembranoids, cherbonolides F-L (1-7). The chemical structures of 1-7 were determined by spectroscopic methods, including infrared, one- and two-dimensional (1D and 2D) NMR (COSY, HSQC, HMBC, and NOESY), MS experiments, and a chemical reduction of hydroperoxide by triphenylphosphine. The anti-inflammatory activities of 1-7 against neutrophil proinflammatory responses were evaluated by measuring their inhibitory ability toward N-formyl-methionyl-leucyl-phenylalanine/cytochalasin B (fMLF/CB)-induced superoxide anion generation and elastase release in primary human neutrophils. The results showed that all isolates exhibited moderate activities, while cherbonolide G (2) and cherbonolide H (3) displayed a more active effect than others on the inhibition of elastase release (48.2% ± 6.2%) and superoxide anion generation (44.5% ± 4.6%) at 30 µM, respectively.

Most new compounds exhibited significant cytotoxic activity against a limited panel of cancer cell lines, and the structure-activity relationship was studied. Compounds 1-7 were found to display significant in vitro anti-inflammatory activity in LPS-stimulated RAW264.7 macrophage cells by inhibiting the expression of the iNOS protein. Compound 4 was also found to effectively reduce the level of COX-2 protein.
