چکیده
The pentacyclic triterpenes rhoiptelenol and rhoiptelenone have been isolated from Sideritis macrostachya. Rhoiptelenone is a new natural compound, whose structure has been determined as D:B-friedo-urs-5-en-3-one. The 1H and 13C NMR spectra of rhoiptelenol, rhoiptelenol acetate and glutinol have been reassigned. The natural occurrence of the D:B-friedo-ursene and D:B-friedo-oleanene derivatives has been examined.

AIMS Pentacyclic triterpenes are a group of molecules with promising anticancer potential, although their precise molecular target remains elusive. The current work aims to investigate the antiproliferative and associated mechanisms of triterpenes in breast cancer cells in vitro. MAIN METHODS Effect of triterpenes on cell cycle distribution, ROS and key regulatory proteins were analyzed in th...
متن کاملBiologically active pentacyclic triterpenes and their current medicine signification
Pentacyclic triterpenes are produced by arrangement of squalene epoxide. These compounds are extremely common and are found in most plants. There are at least 4000 known triterpenes. Many triterpenes occur freely but others occur as glycosides (saponins) or in special combined forms. Pentacyclic triterpenes have a wide spectrum of biological activities and some of them may be useful in medicine...
متن کاملInhibition of Human Neutrophil Elastase by Pentacyclic Triterpenes
SCOPE Inhibiting human neutrophil elastase (HNE) is a promising strategy for treating inflammatory lung diseases, such as H1N1 and SARS virus infections. The use of sivelestat, the only clinically registered synthesized HNE inhibitor, is largely limited by its risk of organ toxicity because it irreversibly inhibits HNE. Therefore, potent reversible HNE inhibitors are promising alternatives to s...
