Periplogenin (PPG), a cardiac glycoside prepared from Cortex periplocae, with similar structure to bufalin, has been found to induce apoptosis in many tumor cells. However, lots of cardiac glycosides possessing strong antitumor activity in vitro have still not passed phase I clinical trials, mostly
In the present study, a 75% ethanol extract of Streptocaulon juventas (SJ), which had a strong inhibitory effect on the proliferation of human lung A549 adenocarcinoma cells, was subjected to bioassay-guided fractionation. The most active fraction (SJF) was obtained using a macroreticular resin
Background: Periplogenin (PPG), a natural compound isolated from traditional Chinese herb Cortex Periplocae, has been reported to possess anti-inflammatory and anti-cancer properties.
Objective:
From remaining aqueous fraction of the roots of Streptocaulon juventas, one new cardiac glycoside named periplogenin 3-O-β-gentiobioside (1) together with six known ones (2-7) were isolated. Their relative structures were elucidated based on NMR spectroscopic
From the methanol extract of the stem bark of the African tree Antiaris africana Engler, two new bioactive metabolites were isolated, namely, the α-amyrin derivative 1β,11α-dihydroxy-3β-cinnamoyl-α-amyrin (antiarol cinnamate, 1) and a cardiac glycoside,
Periplocae Cortex is a traditional Chinese medicine in China, which is mainly produced in northeast China, north China, northwest China, southwest China. In recent years, the increasing in-depth research resulted in the discovery of anti-tumor and cardiac pharmacological activities of Periplocae
Periplocin is a cardiac glycoside and has been used widely in the clinic for its cardiotonic, anti-inflammatory and anti-tumor effects. Although it is taken frequently by oral administration in the clinic, there have been no reports demonstrating that periplocin could be detected in vivo after an
BACKGROUND
During a screening of Chinese plants traditionally used for the treatment of cancer and related diseases, extracts of the root bark of Periploca sepium Bunge showed strong cytotoxic activity.
OBJECTIVE
Isolate and identify cytotoxic compounds from P. sepium and investigate the effects and
