Holothurins B(2), B(3), and B(4), new triterpene glycosides from mediterranean sea cucumbers of the genus holothuria.
TLDR
Three new monosulfated biosides, holothurins B(2) (1), B(3) (2), and B(4) (3), along with the previously known holothsurins A (4) and B (5) were isolated from the sea cucumber H. polii.
Constituents of the sea cucumber Cucumaria okhotensis. Structures of okhotosides B1-B3 and cytotoxic activities of some glycosides from this species.
TLDR
Three new triterpene oligoglycosides, okhotosides B 1, B 2, and B 3, have been isolated from the sea cucumber Cucumaria okhotensis and the structures of 1- 3 were elucidated on the basis of their spectroscopic data (2D NMR and MS).
Triterpene glycosides from the Far-Eastern sea cucumber Pentamera calcigera. 1. Monosulfated glycosides and cytotoxicity of their unsulfated derivatives.
Three new monosulfated triterpene glycosides, calcigerosides B (2), C(1) (3), and C(2) (4), along with the known cucumarioside G(2) (1), have been isolated from the sea cucumber Pentamera calcigera.
Nine New Triterpene Glycosides, Magnumosides A1–A4, B1, B2, C1, C2 and C4, from the Vietnamese Sea Cucumber Neothyonidium (=Massinium) magnum: Structures and Activities against Tumor Cells
TLDR
The erythrocytes were more sensitive to the glycosides action than spleenocytes and cancer cells tested and the synergism of effects of radioactive irradiation and compounds 3 and 7–9 at subtoxic doses on proliferation of DLD-1 cells was demonstrated.
Triterpene glycosides from Antarctic sea cucumbers. 1. Structure of liouvillosides A1, A2, A3, B1, and B2 from the sea cucumber Staurocucumis liouvillei: new procedure for separation of highly polar
TLDR
Five new triterpene glycosides, liouvillosides A1 (1), A2 (2), A3 (3), B1 (4), and B2 (5), have been isolated from the Antarctic sea cucumber Staurocucumis liouviellei and a taxonomic revision is proposed.
Triterpene glycosides from the Far Eastern sea cucumber Cucumaria conicospermium.
Four new triterpene glycosides, cucumariosides A(2)-5 (1), A(3)-2 (2), A(3)-3 (3), and isokoreoside A (4), along with the previously isolated koreoside A (5), have been found in the sea cucumber
Triterpene Glycosides from the Sea Cucumber Eupentacta fraudatrix. Structure and Cytotoxic Action of Cucumariosides A2, A7, A9, A10, A11, A13 and A14, Seven New Minor Non-Sulfated Tetraosides and an
Seven new minor triterpene glycosides, cucumariosides A2 (1), A7 (2), A9 (3), A10 (4), A11 (5), A13 (6) and A14 (7) have been isolated from the Far Eastern sea cucumber Eupentacta fraudatrix.
Isolation, structures, and biological activities of triterpenoids from a Penares sp. marine sponge.
Six new triterpenoids (1-6) and the previously known penasterone, acetylpenasterol, and ergosta-4,24(28)-dien-3-one were isolated from a Penares sp. sponge collected from Vietnamese waters.
New scalarane-based sesterterpenes from the sponge Phyllospongia madagascarensis.
TLDR
Two new natural scalaranes were isolated from the Madagascaran sponge Phyllospongiamadagascarensis, together with three previously decribed tetracyclic sesterterpenoids, phyllofolactones F, G, and B, and a new artifactual ethyl ether of scalaradisin B.
Colochirosides B1, B2, B3 and C, Novel Sulfated Triterpene Glycosides from the Sea Cucumber Colochirus robustus (Cucumariidae, Dendrochirotida)
TLDR
Four new triterpene glycosides, colochirosides B1, B2, B3 and C have been isolated from the sea cucumber Colochirus robustus and demonstrated strong effects, whereas compounds 1 and 2 containing the hydroxy-group in the side chains showed moderate hemolytic activity and were not cytotoxic.
