Abstract

SteroidsSteroids U 0300 Steroidal Polyols from Far-Eastern Starfishes Henricia sanguinolenta and H. leviuscula leviuscula. -The isolation and structure elucidation of two new steroidal polyols (I) and (II), both exhibiting moderate cytostatic activity with respect to the eggs of sea urchin Strongylocentrotus intermedius, are presented. -(LEVINA*, E.

New Polar Steroids from Starfish

“…Natural Product Communications Vol. 3 (10) activity in respect to the developing sea-urchin eggs was found for the tyrammonium salt (58). The salt (58) was also isolated from the starfish Aphelasterias japonica [23].…”

“…A series of other new polyhydroxylated compounds have been isolated from Far-Eastern starfish by our group. For instance, investigation of Henricia sanguinolenta and H. leviuscula leviuscula gave two new polar steroids 38-39 [9,10]. The tetraol 38 has an uncommon 3β,6β,15β-trihydroxysteroid nucleus, while 39 contains a rare 15-ketone fragment, like compounds 25-31.…”
