Abstract
The action of (20R)-cholesta-5,25-diene-3 alpha,4 beta,21-triol 3,21-d isulfate and its 25,26-dihydro-analog from the Pacific brittle star Op hiopholis aculeata was studied on mouse cancer cells, lymphocytes and erythrocytes. The cytotoxic and hemolytic effects were not observed fo r both steroids at the wide range of concentrations. Both steroids inh ibited H-3-Thymidine (but not H-3-Uridine) incorporation into Ehrlich carcinoma cells. It was the first time shown that some sulfated marine polyhydroxylated steroids stimulate the influx of Ca2+ into cells. (2 0R)-Cholesta-5,25-diene-3 alpha,4 beta,21-triol 3,21-disulfate was two times more active than its 25,26-dihydro-analog.
