J. Shin et al., Euplexides A-E: Novel farnesylhydroquinone glycosides from the gorgonian Euplexaura anastomosans, J ORG CHEM, 64(6), 1999, pp. 1853-1858
Euplexides A-E (1-5), novel farnesylhydroquinone glycosides of the moritosi
de class, have been isolated from the gorgonian Euplexaura anastomosans. Th
e structures of these compounds have been elucidated by combined chemical a
nd spectral methods. The absolute stereochemistry has been determined by th
e modified Mosher's method and an acidic hydrolysis followed by GC analysis
. These compounds exhibited moderate cytotoxicity and antioxidizing activit
y as well as inhibitory activity against PLA(2).
