Hemolytic polar steroidal constituents of the starfish Aphelasterias japonica

A reinvestigation of the polar steroid fraction from the starfish Aphelasterias japonica, collected near the Russian shore of the Sea of Japan, has afforded two new compounds, the disulfated quinovoside aphelasteroside C (1) and the monosulfated polyhydroxysteroid aphelaketotriol (2). Compounds 1 and 2 contain a unique 23-oxo-24-hydroxylated side chain that is unprecedented in marine steroids. The known compounds cheliferoside L1 (3), 3-O-sulfoasterone (4), forbeside E3 (5), and 3-O-sulfothornasterol A (6) were also isolated from this source. Compounds 1-3, 5, and 6 showed hemolytic activity to mouse erythrocytes.

Total synthesis of starfish saponin goniopectenoside B

Star quality: Goniopectenosidea...B, a minor asterosaponin from starfish Goniopecten demonstrans with antifouling activity, has been synthesized in a convergent 21a€...steps and in 4.3 % overall yield starting from adrenosterone. This represents the first synthesis of a complex asterosaponin, which are ubiquitous and characteristic in starfish as defense chemicals (see figure). Copyright

Thermal Degradation of Glycosides, V - Hydrothermolysis of Triterpenoid and Steroid Glycosides

In this paper the hydrothermolysis of triterpenoid and steroid glycosides is described.By mere heating with water or water/1,4-dioxane solution, the triterpenoid and steroid glycosides 1, 4 and 15, 16, 25, 29, respectively, are converted into their aglycones and prosapogenins.Furthermore, hydrothermolysis of the triterpenoid 3,28-O-bisglycosides 5, 6, 8, 9, 12 affords the corresponding 3-O-glycosides and reduced oligosaccharides formed by selective cleavage of the ester glycosidic linkage.It is expected that this hydrothermolysis is useful for the structure determination of some triterpenoid and steroid glycosides and for yielding new oligosaccharides.The hydrothermolyzed products have been isolated by chromatography and their structures elucidated by spectroscopic methods.Key Words: Degradation, thermal / Thermolysis / Glycosides / Carbohydrates / Triterpenoids / Steroids
