Pseudolaric acid B is primarily investigated for its potential anticancer properties. It has shown activity against various cancer cell lines by inducing apoptosis and inhibiting cell proliferation. Research indicates it may disrupt microtubule formation, which is critical for cell division, making it a candidate for development in chemotherapy agents. It also exhibits antifungal and anti-inflammatory effects, suggesting possible use in treating fungal infections and inflammatory conditions. Most studies remain in the preclinical stage, focusing on understanding its mechanism and optimizing its therapeutic potential.
