Two novel steroid glycosides, sokodosides A and B (1 and 2, respectively), were isolated from the marine sponge Erylus placenta as growth-inhibitory principles against several strains of yeast and a cancer cell line. Sokodosides possess the novel carbon skeleton as characterized by the presence of a combination of isopropyl side chain and the 4,4-dimethyl steroid nucleus. Sokodoside B has another unique characteristic in the presence of delta(8,14,16) unsaturation. The structures of sokodosides… Expand
Steroids glycosylated with both D- and L-arabinoses from the South China Sea gorgonian Dichotella gemmacea.
Three new 19-hydroxy steroidal glycosides were isolated together with the known analogue junceelloside C from the South China Sea gorgonian Dichotella gemmacea and found to have sugar moieties of both β-l- and β-d-arabinopyranoses by HPLC analysis of their thiocarbamoyl-thiazolidine derivatives and those of authentic d- and l-Arabinoses.

Crellasterones A and B: A-Norsterol Derivatives from the New Caledonian Sponge Crella incrustans
Two new steroids, crellasterones A and B, together with the previously reported compound chalinasterol and several nucleosides, were isolated from the sponge Crella incrustans, collected in New Caledonia and revealed unprecedented marine natural products with a ring-contracted A-norsterone nucleus and 2-hydroxycyclopentenone chromophore.

Pregnane steroids from a gorgonian coral Subergorgia suberosa with anti-flu virus effects
Five new pregnane-type steroids namely subergorgols T-X (1-5) and three known analogues (6-8) were isolated from a gorgonian coral Subergorgia suberosa, and 1,2-dehydroprogesterone exerted potent inhibition against A/WSN/33 virus. Expand

Isolation and structures of erylosides from the Carribean sponge Erylus goffrilleri.
Eight new triterpene glycosides isolated from the sponge Erylus goffrilleri collected near Arresife-Seko Reef (Cuba) contain new variants of carbohydrate chains with two ( 5- 7) and three ( 8) sugar units, respectively. Expand
New triterpene oligoglycosides from the Caribbean sponge Erylus formosus.
Seven new triterpene glycosides were isolated from the sponge Erylus formosus collected along the Caribbean coast of Mexico and proved to be glycoconjugates of 24-methylene-14-carboxy-lanost-8(9)-en-3β-ol. Expand
