Abstract
: Berberine (BBR) is a quaternary ammonium alkaloid isolated from the Traditional Chinese Medicine Coptis chinensis. It possesses a plethora of pharmacological activities because its unique structure properties make it readily interact with macromolecules through π-π stacking and electrostatic interaction. Its anti-tumor effects are receiving more and more attention in recent years. Cytotoxicity and anti-proliferation are the important anti-tumor modes of BBR, which have been studied by many research groups. : This study aims to review the structural modifications of BBR and its cytotoxic derivatives. Also, to study the corresponding structure-activity relationship. BBR showed potential activities toward tumor cells, however, its modest activity and poor physicochemical properties hindered its application in clinical. Structural modification is a common and effective approach to improve BBR's cytotoxic or anti-proliferative activities. : The structural modifications of BBR, the cytotoxic or anti-proliferative activities of its derivatives, and the corresponding structure-activity relationship (SAR) were summarized in the review. : The concluded SAR of BBR derivatives with their cytotoxic or anti-proliferative activities will provide great prospects for the future anti-tumor drug design with BBR as the lead compound.
