Polyphyllin II is widely studied for its potent anticancer properties. It has shown significant activity against various cancer cell lines, including liver, lung, breast, and colorectal cancers, by inducing apoptosis and inhibiting cell proliferation. The compound also demonstrates anti-inflammatory and antimicrobial effects, making it valuable in developing therapeutic agents. Due to its ability to disrupt cancer cell metabolism and enhance the sensitivity of resistant cells to chemotherapy, it is considered a promising candidate for adjuvant cancer treatment. Additionally, Polyphyllin II is used in research settings to explore signaling pathways involved in tumor growth and cell death.
