Biochem/physiol Actions

Triptolide is a diterpene triepoxide, the principal active ingredient in extracts from the Chinese herb Tripterygium wilfordii hook (TwHF). It is a potent immunosuppressant and anti-inflammatory. Triptolide has been shown to inhibit the expression of IL-2 in activated T cells at the level of purine-box/nuclear factor and NF-κB mediated transcription activation. It synergizes with cyclosporin A in promoting graft survival in animal models and in suppression of graft versus host disease in allogeneic bone marrow transplants. In addition, it induces apoptosis in tumor cells and potentiates tumor necrosis factor (TNF_α) induction of apoptosis in part through the suppression of c-IAP₂ and c-IAP₁ induction.
