Abstract:
Oleanolic acid (OA) is a pentacyclic triterpenoid chemical component that exists in natural plants with a molecular formula of C30H48O3 and a molecular weight at 456.71 g·mol-1. OA is widespread in traditional Chinese herbal medicine (Ligustri Lucidi Fructus, Achyranthis Bidentate Radix, Red Sage) and berries (blueberries, grapes). In recent years, because of the extensive pharmacological effects of OA, its advantages in disease treatment have become increasingly prominent and gradually attracted the attention of pharmaceutical researchers. OA has effective therapeutic effects on a series of chronic diseases such as inflammation, cancer, diabetes, and cardiovascular diseases through mul?tiple signaling pathways and various targets. Especially in cancers, such as colorectal cancer, liver cancer, gastric cancer, lung cancer, breast cancer and other malignancies, OA presents substantial efficacy. However, its poor aqueous solubility, needy bioavailability, and unsatisfactory pharmacological activity excessively restrict its clinical application. More impor?tantly, the improper utilization of OA can cause adverse reactions, toxic effects and even damage to organs in some spe?cific situations. With the discovery of various pharmacological effects, the complex action mechanisms of OA, the contin?uous progress in structural modification of OA, as well as the synthesis of OA derivatives, its application is expand?ing gradually. Among numerous studies, there is a clear indication that OA and its derivatives, if fully developed, may provide an alternative and cheaper treatment for a variety of chronic diseases. However, the specific molecular mecha?nisms of OA and its derivatives as an alternative therapy and supplementary therapy for cancer, diabetes, cardiovascular disease and other chronic diseases remain to be clarified. Therefore, it is necessary to further study the pharmacokinet?ics, pharmacological activity, specific targets and related mechanisms of OA to lay a solid foundation for drug devel?opment and the application of OA in clinical settings.
