Agarofuran sesquiterpenes from Schaefferia argentinensis

Sixteen dihydro-β-agarofuran sesquiterpenes were isolated from the aerial parts of Schaefferia argentinensis. The in vitro antiproliferative activity of the major sesquiterpenes was examined against T47D, MCF7, and MDA human cancer cell lines. The activity observed for the tested compounds is marginal.
