Triptolide, Tripterygium wilfordii-CAS 38748-32-2-Calbiochem

C₂₀H₂₄O₆

360.40

MFCD00210565

A novel diterpene triepoxide isolated from the Chinese herb Tripterygium wilfordii that acts as a potent immunosuppressant and anti-inflammatory agent. Induces apoptosis in tumor cells, sensitizes tumor cells to TNF-α-induced activation of NF-κB. Also inhibits IL-2 expression in activated T-cells at the level of purine-box/nuclear factor and NF-κB transcriptional activation. Also reported to inhibit mitogen activated protein kinase phosphatase-1 (MKP-1). Reported to induce apoptosis by activating DEVD-cleaving caspases.
