Preclinical evidences toward the use of triterpenoid CDDO-Me for solid cancer prevention and treatment
Cet article passe en revue les études précliniques concernant l'efficacité d'un triterpénoïde de synthèse dérivé de l'oléanane (le CDDO-Me) dans la chimioprévention et le traitement des cancers, puis présente les mécanismes moléculaires impliqués
Solid cancer remains a major cause of death in the world. As limited treatment options are currently available to patients with solid cancer, novel preventive control and effective therapeutic approaches are considered to be reasonable and decisive measures to combat this disease. The plant-derived triterpenoids, commonly used for medicinal purposes in many Asian countries, poses various pharmacological properties. A large number of triterpenoids exhibit cytotoxicity against a variety of cancer cells, and cancer preventive, as well as anticancer efficacy in preclinical animal models. To improve antitumor activity, some synthetic triterpenoid derivatives have been synthesized, including cyano-3,12-dioxooleana-1,9(11)- dien-28-oic (CDDO), its methyl ester (CDDO-Me), and imidazolide (CDDO-Im) derivatives. In this review, we will critically examine the current preclinical evidences of cancer preventive and therapeutic activity about one of the synthetic triterpenoids, CDDO-Me. Both in vitro and in vivo effects of this agent and related molecular mechanisms are presented.
