Triptolide is a diterpene triepoxide, immunosuppresive agent extracted from the Chinese herb Tripterygium wilfordii. It functions as a NF-κB inhibitor with dual actions by disruption of p65/CBP interaction and by reduction of p65 protein. Triptolide (PG490) abrogates the transactivation function of heat shock transcription factor 1 (HSF1). Triptolide inhibits MDM2 and induces apoptosis through a p53-independent pathway.
