Halogenated monoterpenes from plocamium costatum and their biological activity1



Halogenated monoterpenes from plocamium costatum and their biological activity1



Journal of Natural Products 62(2): 383-385



From the dichloromethane solubles of the temperate red alga Plocamium costatum, one new [1,4-dibromo-2,3,6-trichloro-3, 7-dimethyl-7-octene] (1) and three previously reported polyhalogenated monoterpenes (2-4), and the known phytol derivative 3,7,11,15-tetramethylhexadec-1-en-3-ol (1-phyten-3-ol, 5) were isolated. The structure of 1 was deduced from its spectroscopic data. For compound 3, complete 1H and 13C NMR data are reported for the first time. The CH2Cl2 extract and compounds 3 and 5 deterred settlement of barnacle larvae, suggesting a potential ecological role of these isolates.
