Periplocin
Periplocin is a plant-derived glycoside whereby the sugar moiety is linked to a steroid. It can be extracted from cortex periplocae (CPP), the dry root of Periploca sepium.[1][2]
CPP's healing activities have long been recognized in traditional Chinese medicine[2] where it has been used to treat rheumatoid arthritis.[1] Scientific studies of CPP have identified over 100 components of which periplocin has been a major focus both for its toxicity as well as for its potential beneficial pharmaceutical effects.[1] Besides the cardiac glycosides with periplocin as its main constituent, the CPP contains different C21-steroidal glycosides such as periplocodides and pregnene derivatives, fatty acids, volatile oils, terpenes, and others.[1]
Higher doses of periplocin are toxic as a cardiac glycoside.[3]
Potential medical applications of periplocin are focused on these areas:[1]
- Anti-inflammatory effects. Periplocin and its derivatives have shown anti-inflammatory effects.
- Antitumor activity. A number of in vivo and in vitro studies suggest that periplocin inhibits tumor growth. Studies show both inhibition of growth as well as induction of apoptosis.
- Cardiotonic activity. Traditional use includes an application for heart failure. Structure and function of cardiac muscle were improved in rats.
Periplocin's metabolites, periplocymarin and periplogenin,[4] have also shown some pharmacological effects.
