polyphyllin d/paris quadrifolia

Polyphyllin D (PD), an active component from a traditional medicinal herb Paris polyphylla, which has long been used for the treatment of cancer in Asian countries, has been found to hold significant antitumor activity in vivo or in vitro. However, there were few reports on the effects and

OBJECTIVE We evaluated the effects of polyphyllin D (PD), a natural compound with anti-neoplastic activity and a major component of the Chinese herb Paris polyphylla, on ovarian cancer (OVCA) cell line proliferation and platinum sensitivity. METHODS A panel of 20 OVCA cell lines was subjected to PD

Polyphyllin D (PD) is a potent anticancer agent isolated from a traditional medicinal herb Paris polyphylla that has been used in China for many years to treat cancer. PD is not a substrate of p-glycoprotein, and it can bypass the multi-drug resistance in cancer cell line R-HepG2. However, the

BACKGROUND Angiogenesis, the process of blood vessel formation, is critical to tumour growth. The importance of angiogenesis in tumour development has lead to the development of anti-angiogenic strategies to inhibit tumour growth. In this study, polyphyllin D (PD), an active component in Chinese

In a search for new anticancer agents, we identified a novel compound polyphyllin D (PD) (diosgenyl alpha-L-rhamnopyranosyl-(1-->2)-(alpha-L-arabinofuranosyl)-(1-->4)]-[beta-D-glucopyranoside) that induced DNA fragmentation and phosphatidyl-serine (PS) externalization in a hepatocellular carcinoma
