Pseudolaric Acid A is primarily investigated for its potential in cancer therapy due to its ability to inhibit cell proliferation and induce apoptosis in various tumor cell lines. It has shown particular activity against leukemia, hepatoma, and breast cancer cells by disrupting microtubule formation, which is critical for cell division. This antimitotic property makes it a candidate for development as a chemotherapeutic agent. Additionally, Pseudolaric Acid A exhibits antifungal activity, especially against skin pathogens like Trichophyton species, suggesting possible use in topical treatments for fungal infections. Research also indicates it may modulate signaling pathways involved in inflammation and immune response, opening avenues for exploration in autoimmune and inflammatory conditions. However, its clinical application remains limited to preclinical studies due to challenges in solubility and toxicity.
