Bioactive steroidal sulfates from the ambulakrums of the Pacific starfish Lysastrosoma anthosticta.
???displayArticle.abstract???
Lysaketotriol (1) and lysaketodiol (2), along with two previously known polyhydroxylated steroidal sulfates (3, 4), were isolated from the ethanolic extract of ambulakrums separated from the arms of the starfish Lysastrosoma anthosticta (Sea of Japan). The chemical structures have been elucidated using 1D and 2D NMR spectroscopy (1H, 13C, DEPT, COSY-45, HSQC and HMBC) and mass spectrometry. Compound 1 produced moderate stimulation of lysosomal activity in mouse splenocytes and compounds 1-2 showed immunomodulatory activity.
