Background: Betulinic acid (BA), a pentacyclic triterpenoid saponin widely found in plants, has attracted attention for its diverse pharmacological activities. Recent studies highlight its cardioprotective potential, promoting its relevance in cardiovascular research.
Aim of the review: This review summarizes BA's physicochemical properties, structure-activity relationships, natural sources, and synthesis strategies. It further discusses its pharmacokinetics and toxicity to evaluate its drug development potential, with emphasis on cardioprotective effects and related signaling pathways.
Methods: Literature was collected from databases such as PubMed and Web of Science, focusing on studies addressing BA's chemical characteristics, biological activities, pharmacokinetics, and cardiovascular relevance.
Results: BA exerts cardioprotective effects via multiple signaling pathways, including NRF2, NF-κB, MAPK, and NFAT. These contribute to its antioxidant, anti-inflammatory, anti-apoptotic, and anti-proliferative actions, as well as its enhancement of endothelial function through nitric oxide signaling. BA also reduces lipid accumulation. Combined with favorable physicochemical properties and synthetic accessibility, these findings support BA as a promising multifunctional lead compound in cardiovascular pharmacology.
Conclusion: BA shows strong potential as a cardioprotective natural compound. Although further research is needed to validate its clinical efficacy and safety, its multi-target actions and structural versatility provide a solid basis for development in cardiovascular drug discovery.
