Abstract

Wm was isolated from Cynanchum wilfordii (Asclepiadaceae) as a mixture form of polypregnane glycosides that included wilfoside K1N and wilfoside C1N. In the present study, we investigated the anti-angiogenic effect of wilfoside glycosides using in vivo and in vitro assay systems. We first demonstrated that concentrated conditioned media obtained from Wm-treated HepG2 human hepatoblastoma cells blocked the angiogenic activation of Wm-untreated concentrated conditioned media, suggesting that Wm may have an inhibitory effect on tumor-induced angiogenesis.
