Polyphyllin I is a bioactive constituent found in Paris polyphylla, has strong anti-tumor activity. Polyphyllin I is an activator of the JNK signaling pathway and is an inhibitor of PDK1/Akt/mTOR signaling. Polyphyllin I induces autophagy, G2/M phase arrest and apoptosis. References: Kong M, et al.
