Dendrilla cactos, bastadins

A Guam specimen of Ianthella basta has afforded the novel 34-O-sulfatobasta-din-9 (2127) (1855), and the sponge Dendrilla cactos from India has yielded bastadins-22 (2128) and -23 (2129) (1899).

The other series is the bastadins, named after the Australian species lanthella basta, from which most bastadins were isolated (Kazlauskas et al., 1981). They are formally peptides that are derived, as in other verongid sponges, from bromotyrosine. With the exception of bas-tadin 14, which was isolated from Psammaplysilla purpurea, and bastadins 22 and 23 from Dendrilla cactos, almost all bastadins were extracted from species of the genus lanthella, most often from lanthella basta. The latest member of the series is bastadin 26, isolated from the Australian species lanthella flabelliformis (Calcul et al., 2010b Carroll et al, 2010).
