Steroids from the Cold Water Starfish Ctenodiscus crispatus with Cytotoxic and Apoptotic Effects on Human Hepatocellular Carcinoma and Glioblastoma Cells
Bulletin of the Korean Chemical Society (Print)
Chemical investigation on the methanol extract of the starfish Ctenodiscus crispatus resulted in the isolation of five steroids, (22E,24ξ)-26,27-bisnor-24-methyl-5α-cholest-22-en-3β,5,6β,15α,25-pentol 25-O-sulfate (1), (22E,24R,25R)-24-methyl-5α-cholest-22-en-3β,5,6β,15α,25,26-hexol 26-O-sulfate (2), (28R)-24-ethyl-5αcholesta-3β,5,6β,8,15α,28,29-heptaol-24-sulfate (3), (25S)-5α-cholestane-3β,5,6β,15α,16β,26-hexaol (4), and Δ7-sitosterol (5). Their structures were identified by extensivedoi:10.5012/bkcs.2014.35.8.2335 fatcat:4cvaptvk5zckhjhpdapagyyygq
