A. Zampella et al., Amphiasterins: a new family of cytotoxic metabolites from the marine sponge Plakortis quasiamphiaster, TETRAHEDRON, 57(1), 2001, pp. 257-263
A new family of marine metabolites, named amphiasterins (1-17), was isolate
d from the marine sponge Plakortis quasiamphiaster. They can be divided in
five structurally homogeneous groups, whose components differ only in the l
ength and/or in the unsaturation degree of the alkyl side chain. The struct
ures of these compounds were elucidated by spectroscopic data. (C) 2000 Els
