Astropecten latespinosus

Astropecten latespinosus and Astropecten scoparius were also added to the list ofTTX-bearingechinoderms (Maruyamaet a/., 1984,1985 Miyazawa et a/., 1985) from the results of toxicity examination of starfish collected from all over Japan. In the mouse assay, A. latespinosus and A. scoparius showed the toxicity scores of 13 and 5.7 MU/g, respectively. These findings made sure of TTX intoxication mechanism in gastropods to come from their food chain. Afterward, TTX study gave a clue to be expanded in many aspects. In 1985, TTX was also reported from starfish A. polyacanthus and A. scoparius from Seto Inland Sea, Japan, with the highest toxicity scores of 520 and 46 MU/g, respectively (Miyazawa et al., 1985). 

The same methods were utilized to determine the structures of two oligoglycosides (942) and (943) from Astropecten latespinosus after they had been desulfated by solvolysis 630), thornasteroside A (920) and a new saponin, versicoside A (944), from Asterias amurensis versicolor 631), and four new compounds, the luidiaglycosides A-D (945-948), from Luidia maculata 632, 633). Luidiaglycosides C (947) and D (948) contain the aglycones marthasterone and dihydromarthasterone which... 

Komori et al. (555) reported the isolation of a cerebroside mixture (987) and two nucleosides, thymine desoxyribonucleoside (988) and uracil desoxyribonucleoside (989), from Acanthaster planci. Structure elucidation was based on and C-NMR spectrometry as well as on El- and FD mass spectrometry. Similar cerebroside mixtures which showed nearly identical IR-spectra could be extracted from Luidia qui naria and Astropecten latespinosus. The mycosporine-like amino acids (990-994) have been obtained from alcoholic extracts of the starfish Asterina pectinifera 656).
