, p. 731 - 736 (1988)
An allelopathic substance was isolated from the methanol extract of the brown alga, Cladosiphon okamuranus.Extraction and purification of the active substance was monitored by bioassays against the conchospores of Porphyra yezoensis and Heterosigma akashiwo.The compound was identified as 6Z,9Z,12Z,15Z/octadecatetraenoic acid and its activity was then tested againts 36 species of microalgae.Many of eukaryotes tested were affected at 5 ppm, but prokaryotes were unaffected at 25 ppm.The tetraunsaturated fatty acid exterminated toxic red tide planktons such as Chattonella antiqua at 1 ppm concentration.Key Word Index-Cladosiphon okamuranus; Chordariaceae; brown alga; allelopathy; red tide; toxic phytoplankton; fatty acid; octadecatetraenoic acid.
Synthesis of Rare Polyunsaturated Fatty Acids: Stearidonic and ω-3 Arachidonic
Golovanov,Ivanov,Groza,Myagkova
, p. 1038 - 1041 (2016/02/18)
Total chemical syntheses of the rare natural ω-3 C18 and C20 fatty acids, which possess potential antiinflammatory activity, were elaborated for subsequent studies of their biological activity.
Concise syntheses of three ω-3 polyunsaturated fatty acids
Jakobsen, Martin Gjerde,Vik, Anders,Hansen, Trond Vidar
, p. 5837 - 5839 (2013/01/13)
The synthesis of the three ω-3 polyunsaturated fatty acids, eicosatetraenoic acid (3), docosapentaenoic acid (4), and stearidonic acid (5) has been achieved using eicosapentaenoic acid or docosahexaenoic acid as the starting materials.
Sarcoglycosides A-C, new O-glycosylglycerol derivatives from the South China sea soft coral Sarcophyton infundibuliforme
Li, Liang,Wang, Chang-Yun,Shao, Chang-Lun,Guo, Yue-Wei,Li, Guo-Qiang,Sun, Xue-Ping,Han, Lei,Huang, Hui,Guan, Hua-Shi
experimental part, p. 1495 - 1502 (2009/10/17)
Chemical examination of the soft coral Sarcophyton infundibuliforme collected from the South China Sea resulted in the isolation of the three new O-glycosylglycerol derivatives sarcoglycosides A-C (1 - 3), together with two known compounds, chimyl alcohol
A new digalactosyl diacylglycerol from a cultured marine dinoflagellate Heterocapsa circularisquama
Hiraga, Yoshikazu,Kaku, Ken,Omoda, Daisuke,Sugihara, Kinuko,Hosoya, Hiroshi,Hino, Mizuki
, p. 1494 - 1496 (2007/10/03)
A new digalactosyl diacylglycerol (1) has been isolated from the cultured marine dinoflagellate Heterocapsa circularisquama together with known monogalactosyl diacylglycerols 2 and 3, and their structures were elucidated by spectroscopic methods. The digalactosyl diacylglycerol 1 showed cytolytic activity toward heart cells of oysters.
