Descrizione

Applicazioni

Triptolide has been used as a NF-κB inhibitor to study the inhibition of cell invasion and angiogenesis in human thyroid cancer cells⁶. Triptolide has also been used to study its apoptotic effects in anaplastic thyroid cancer cells⁷.

Azioni biochim/fisiol

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.

Nota sulla preparazione

Triptolide is soluble in DMSO. The stock solution should be stored in DMSO at -20 deg C after reconstitution.
