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.^[2][3]

CPP's healing activities have long been recognized in traditional Chinese medicine^[3] where it has been used to treat rheumatoid arthritis.^[2] 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.^[2] 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.^[2]

Higher doses of periplocin are toxic as a cardiac glycoside.^[4]

Potential medical applications of periplocin are focused on these areas:^[2]

• 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,^[5] have also shown some pharmacological effects.

Potential senolytic activity was suggested by an AI structural analysis of over 4,000 chemicals in 2013.^[6]
