Chemical Constituents and Bioactivities of Starfish

“…Luidia maculata contained thornasteroside A (466), marthasterosides A 2 , B, and C (474 -476, resp. ), and maculatoside (477) [134] [143].…”

Starfish Saponins, Part 18. Steroidal Glycoside Sulfates from the Starfish Linckia laevigata

“…The number of reported structures of asterosaponins, "sulfated steroidal glycosides," is rapidly growing. Following the structure elucidation of thornasteroside A, the major Acanthaster planet saponin, by Kitagawa and Kobayashi in 1978 (1), a number of novel structures have been recently described (2)(3)(4)(5)(6)(7)(8)(9)(10). All these compounds have common structural features.…”
