 Use of Triptophenolide


Triptophenolide is a colorless crystalline plate isolated from ethyl acetate extracts of Tripterygium wilfordii. IC50 value:Target:In vitro: Triptophenolide can remarkably inhibit the delayed type hypersensitivity (DTH) reaction induced by DNCB and BSA; and diminished the peripheral blood ANAE+lymphocytes in rats and micc. Moreover, triptophenolide can dramatically increase the amount of total serum complement and significautly decrcase the serum antibody products (1gG ) of rats and mice. The phagocytosis of perioneal exudate macrophages in mice present double effects in vitro [1].In vivo:
