Xc. Frette et al., NEW BIOLOGICALLY-ACTIVE PECTINOACETAL-RELATED STEROLS FROM THE GORGONIAN CTENOCELLA SP, Tetrahedron letters, 37(17), 1996, pp. 2959-2962
Based on a bio-assay guided fractionation, a new sterol has been isola
ted as an equilibrium of isomers 1 with interesting cancer cell antipr
oliferative properties from a yet undescribed species of the genus Cte
nocella sp. The structure of this sterol has been inferred from the ac
etyl derivative 2, on the basis of spectral study. (C) 1996 Elsevier S
