Abstract
AbstractMarine organisms are the important source of the bioactive metabolites. A novel enolic sulfated sterol, arenicolsterol A, has been isolated from a marine annelid Arenicola cristata collected in the coast of Mainland of China. The structure was elucidated using all sorts of spectroscopic data including ESIMS, 1D and 2D NMR etc. The cytotoxic bioactivity of this sterol was evaluated by MTT assay. It could inhibit the growth of human cervix cancer cell line (Hela) and human non‐small cell lung cancer cell line (NCI‐h6) with IC50 of (3.1±0.6) µg/mL and (7.6±0.8) µg/mL.
