Cinchonine
Based on 5 publication(s) in Google Scholar
Cinchonine is a natural compound present in Cinchona bark with antimalarial, antitumor, anti-inflammatory, anti platelet-aggregation and anti-obesity properties. Cinchonine inhibits cells proliferation and autophagy and induces apoptosis through activation of Caspase-3. Cinchonine activates endoplasmic reticulum stress-induced apoptosis in human liver cancer cells.
