(5R)-5-hydroxytriptolide (LLDT-8) is a novel triptolide analog that has been identified as a promising candidate for treating autoimmune diseases and has been shown to be effective in treating murine collagen-induced arthritis and lupus nephritis. LLDT-8 is extracted from the Chinese traditional herb Tripterygium wilfordii Hook. f. (TWHF). It exhibits anti-inflammatory and immunosuppressive effect both in vitro and in vivo. LLDT-8 is in Phase II clinical trial involving RA patients in China.

Sample Use Guides

In Vivo Use Guide
The mice were orally treated with LLDT-8 (0.125 mg/kg, every other day)
Route of Administration: Oral
The CC50 values of triptolide and LLDT-8 were 2.1 ± 0.3 and 256.6 ± 73.8 nM, respectively. LLDT-8 significantly inhibited the proliferation of splenocytes induced by concanavalin A (ConA), lipopolysaccharide (LPS), or mixed lymphocyte reaction (MLR), and the IC50 values were 131.7 ± 32.4, 171.5 ± 17.3, and 38.8 ± 5.1 nM, respectively. LLDT-8 (25, 50, 100 nM) dose-dependently reduced the production of Th1 type cytokines (IFN-γ, IL-2) and inflammatory cytokines (TNF-α, IL-6) in vitro.
