Asterosaponins from the Far Eastern starfish Leptasterias ochotensis and their anticancer activity.
نویسندگان
چکیده
Six new asterosaponins, leptasteriosides A-F (3-8), one new and one previously known asterogenins (1, 2) were isolated from the alcoholic extract of the Far Eastern starfish Leptasterias ochotensis. The structures of 1-8 were elucidated by extensive NMR and ESI-MS techniques. Compounds 2-8 showed slight or moderate cytotoxic activities against cancer cell lines RPMI-7951 and T-47D. The asterosaponins 3-5 demonstrated a significant inhibition of RPMI-7951 and T-47D cell colony formation in soft agar clonogenic assay in nontoxic doses.

Three new sulfated steroid monoglycosides, leptaochotensosides A-C (1-3), and a new sulfated polyhydroxylated steroid (4) were isolated from the alcoholic extract of the Far Eastern starfish Leptasterias ochotensis. The structures of compounds 1-4 were established by extensive nuclear magnetic resonance (NMR) and electrospray ionization mass spectrometry (ESIMS) analyses and chemical transforma...
متن کاملA new sea star of the genus Leptasterias (Asteroidea: Asteriidae) from the Aleutian Islands.
A new species of asteriid sea star of the genus Leptasterias (Order Forcipulatida) is described from the nearshore waters of the Aleutian Islands. Leptaterias tatei sp. nov. is distinguished from Leptasterias stolacantha Fisher, 1930, by the characteristics of the spines and pedicellariae. Geographic distribution is discussed and a key to the five-rayed Leptasterias of the Aleutian Islands is p...
متن کاملAsterosaponins from the Starfish Astropecten monacanthus suppress growth and induce apoptosis in HL-60, PC-3, and SNU-C5 human cancer cell lines.
Using various chromatographic experiments, six asterosaponins (1-6) were isolated from the MeOH extract of the Vietnamese starfish Astropecten monacanthus. The cytotoxic activities of the MeOH extract and six asterosaponins were evaluated on three human cancer cell lines, HL-60 (promyelocytic leukemia), PC-3 (prostate cancer), and SNU-C5 (colorectal cancer). Relative to the effects of the posti...
متن کاملPrespawning Behavior, Spawning, and Development of the Brooding Starfish Leptasterias polaris.
Our study focused on the precise reproductive behavior of the starfish Leptasterias polaris (Muller and Troschel) before and during spawning--a subject of much speculation and evident ecological importance. Between the third week of December 1992 and mid-January 1993, we observed spawning in the laboratory that roughly corresponded to field observations in the Lower St. Lawrence Estuary. In exp...
