sarcophyton/neoplasms

Active compounds from natural products have been widely studied. The anti-tumor effects of 13-acetoxysarcocrassolide isolated from Formosan soft coral Sarcophyton crassocaule on bladder cancer cells were examined in this study. An MTT assay showed that 13-acetoxysarcocrassolide was cytotoxic to

An antitumorigenic effect of sarcophytol A (SaA), a simple monohydroxycembratetraene isolated from a marine soft coral Sarcophyton glaucum, was investigated in rat colon carcinogenesis. Three groups (26 rats each) of female CD-Fischer rats given an intrarectal dose of 2 mg of N-methyl-N-nitrosourea

A new metabolite 1 has been isolated from the marine soft coral Sarcophyton ehrenbergi along with two known diterpenoids 2 and 3 and cholesterol 4. The structure of 1 was determined by means of detailed spectroscopic analysis and unambiguously confirmed to have the S configuration by the synthesis

The combination of liquid chromatography coupled to high resolution mass spectrometry (LC-HRESMS)-based dereplication and antiproliferative activity-guided fractionation was applied on the Red Sea-derived soft coral Sarcophyton sp. This approach facilitated the isolation of five new

Three new cembrene diterpenoids, sarcoehrenbergilid A-C (1-3), along with four known diterpenoids, sarcophine (4), (+)-7α,8β-dihydroxydeepoxysarcophine (5), sinulolide A (6), and sinulolide B (7), and one steroid, sardisterol (8), were isolated and characterized from a solvent extract of the Red Sea

Ten biscembranoids (1-10), including the two new compounds sarcophytolides M and N (1 and 2), were isolated from the methanol extract of the Vietnamese soft coral Sarcophyton pauciplicatum. Their structures were elucidated by spectroscopic methods including one dimensional (1D)- and 2D-NMR,

Two new cytotoxic tetracyclic tetraterpenoids, methyl tortuoate A (1) and methyl tortuoate B (2), along with the known methyl sartortuoate (3) were isolated from the soft coral Sarcophyton tortuosum. The structures of 1 and 2 were established by spectroscopic methods, mainly on the basis of 2D NMR

Four new cembranoids, sarcophelegans A-D (1-4) and six known analogues (5-10) were isolated from the South China Sea soft coral Sarcophyton elegans. Their structures were elucidated through detailed spectroscopic analysis, and the absolute configuration of 1 was confirmed by single-crystal X-ray

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

Chemical investigation of the octocoral Sarcophyton ehrenbergi led to the isolation of six new cembranoids, (+)-12-carboxy-11Z-sarcophytoxide (1), (+)-12-methoxycarbonyl-11Z-sarcophine (3), ehrenberoxides A-C (4-6), and lobophynin C (2), along with two known compounds, (+)-sarcophytoxide (7) and

Five new cembranoids, sarcocrassocolides A-E (1-5), along with three known cembranoids 6-8, have been isolated from a Formosan soft coral Sarcophyton crassocaule. The structures of the new metabolites were elucidated by extensive spectroscopic analysis and the absolute configuration of 1 was

Three new cembranoids, sarcocrassocolides M-O (1-3), have been isolated from the soft coral Sarcophyton crassocaule. The structures of the metabolites were determined by extensive spectroscopic analysis. Compounds 1-3 were shown to exhibit moderate cytotoxicity toward a limited panel of cancer cell

Seven new cembranoids, sarcocrassocolides F-L (1-7), have been isolated from a soft coral Sarcophyton crassocaule. Their structures were determined by extensive spectroscopic analysis. Most new compounds exhibited significant cytotoxic activity against a limited panel of cancer cell lines, and the

Chemical examination from the cultured soft coral Sarcophyton digitatum resulted in the isolation and structural identification of four new biscembranoidal metabolites, sardigitolides A-D (1-4), along with three previously isolated biscembranoids, sarcophytolide L (5),
