Cytotoxic Polyhydroxysteroidal Glycosides from Starfish Culcita novaeguineae
Four new polyhydroxysteroidal glycosides-culcinosides A-D (1, 2, 4, and 7)-along with three known compounds-echinasteroside C (3), linckoside F (5), and linckoside L3 (6)-were isolated from the ethanol extract of starfish Culcita novaeguineae collected from the Xisha Islands of the South China Sea. The structures of new compounds were elucidated through extensive spectroscopic studies and chemi...
متن کاملStarfish saponins, part 49. New cytotoxic steroidal glycosides from the starfish Fromia monilis.
Nine new cytotoxic steroidal glycosides 1-9 have been isolated from the starfish Fromia monilis collected off New Caledonia. Structures of these compounds, which include four mono-(1-4), two di-(5,6), and three glycosides (7-9), were elucidated through spectral interpretation. Monilosides G [7], H [8], and I [9] are the first tri-glycosides to be found among the group of glycosides of polyhydro...
متن کاملTwo new steroidal saponins from Tribulus terrestris.
Two new steroidal saponins and two known flavonoid glycosides were isolated from the fruits of Tribulus terrestris. Their structures were assigned by spectroscopic analysis and chemical reaction as 26-O-beta-D-glucopyranosyl-(25R)-5 alpha-furostan-12-one-3beta,22 alpha,26-triol-3-O-beta-D-glucopyranosyl (1 --> 2)-beta-D-glucopyranosyl(1 --> 4)-beta-D-galactopyranoside (1), 26-O-beta-D-glucopyra...
متن کاملThree New Steroidal Saponins from Smilax officinalis
Three new steroidal saponins were isolated from the roots of Smilax officinalis Kunth. Their structures were established as (3β,5β,22α,25S)-26-(β-D-glucopyranosyloxy)-22-hydroxyfurostan-3-yl O-α-L-arabinopyranosyl-(1→6)-O-[β-D-glucopyranosyl-(1→4)]-β-D-glucopyranoside, (3β,5α,22α,25S)-26-(β-D-glucopyranosyloxy)-22-hydroxyfurostan-3-yl O-α-L-arabinopyranosyl-(1→6)-O-[β-D-glucopyranosyl-(1→4)]-β-...
متن کاملFeeding Preferences of the Cushion Star Culcita Novaeguineae in the Presence of the Crown of Thorns Starfish Acanthaster Planci
Crown of thorns starfish (Acanthaster planci Linné 1758) are notorious coral reef devastators; they decimate coral populations, thus changing the coral reef habitat and killing many organisms that depend on the coral. Culcita novaeguineae (Muller and Troschel 1842), or cushion stars, are corallivores and generalists that live in Pacific reefs. Because C. novaeguineae and A. planci have similar ...
