Pseudolaric acid B is primarily utilized in the field of medical research due to its potent anti-cancer properties. It has been studied extensively for its ability to inhibit the growth of various cancer cells, particularly in cases of leukemia and liver cancer. The compound works by inducing apoptosis, or programmed cell death, in cancer cells, making it a promising candidate for developing new anti-cancer therapies. Additionally, Pseudolaric acid B has shown potential in reducing inflammation, which could be beneficial in treating inflammatory diseases. Its application in traditional Chinese medicine has also been noted, where it is used for its antifungal and antibacterial properties. Ongoing research continues to explore its full therapeutic potential and mechanisms of action.
