The half-effective dose(ED50), therapeutic index(TI) and certain safety factor(CSF) of 7 diterpene lactone epoxide compounds with antiinflammatory and immunosuppressive action extracted from Tripterygium wilfordii (TW) were assayed using croton oil-induced ear swelling and hemolysin-antibody

[Screening of anti-inflammatory, immunosuppressive and antifertility components of Tripterygium wilfordii V. Effects of 7 diterpene lactone epoxide compounds on the proliferation of T and B lymphocytes in vitro].

In suspension culturing of Tripterygium wilfordii, 18.4 mg/l of dry cells and 9.184 mg/l of diterpene-lactone compounds were obtained from 6,7-V liquid medium containing 1 mg/l NAA. Besides those within the cells, diterpene-lactone compounds were also found in the cultured liquid and the yield

Anti-AIDS agents--XIX. Neotripterifordin, a novel anti-HIV principle from Tripterygium wilfordii: isolation and structural elucidation.

Numai utilizatorii înregistrați pot traduce articole

A new kaurane type diterpene lactone, neotripterifordin (1), has been isolated from the roots of Tripterygium wilfordii. The structure of 1 was elucidated by spectroscopic methods, which included the concerted application of a number of 2-D NMR techniques including 1H-1H COSY, phase-sensitive NOESY,

Anti-AIDS agents, 4. Tripterifordin, a novel anti-HIV principle from Tripterygium wilfordii: isolation and structural elucidation.

A new kaurane-type diterpene lactone, tripterifordin [1], has been isolated from the roots of Tripterygium wilfordii. The structure of 1 was elucidated by spectroscopic methods, including the concerted application of a number of 2D nmr techniques that involved the 1H-1H COSY, heteronucleus-detected
