title: Antiproliferative hopane and oleanane glycosides from the roots of Glinus lotoides.
abstract: Three new hopane saponins, lotoidosides A - C (1 - 3), and four new oleanane saponins, lotoidosides D - G (4 - 7), were isolated from the roots of Glinus lotoides L. (Molluginaceae). Their structures were determined by extensive 1D- and 2D-NMR spectroscopy and ESI-MS analysis. The antiproliferative activity of compounds 1 - 7 was evaluated using three continuous murine and human culture cell lines J774.A1, HEK-293, WEHI-164. Compounds 1 and 3 - 7 showed significant cytotoxicity against the three cancer cell lines with IC50 values ranging from 0.018 to 0.62 microM, while compound 2 exerted a weak activity only against the cell line HEK-293.
