Z = 2, F(000) = 380, Dc= 1. 34g/ cm3. The structure was solved by direct methods and refined by full matrix least-squares method to a final R value of 0. 042 for 1934 reflections with I】 3σ(I). Crystals of triptonide are isostructural with those of triptolide.展开更多

Inflammatory cytokines and inflammatory stimuli ...IL-37 is an anti-inflammatory cytokine that was only recently identified, and it is highly expressed in tissues from patients with inflammatory and autoimmune diseases. Inflammatory cytokines and inflammatory stimuli can induce the upregulation of IL-37. However, it has not been reported whether anti-inflammatory medications induce the expression of IL-37. In this work, we uncovered, for the first time, that two main bioactive components, triptolide and triptonide, from the herb Tripterygium wilfordii Hook f. (TwHF), which possess anti-inflammatory activity, upregulate the expression of IL-37, and this expression was suppressed by ERKI/2 and p38 MAPK inhibitors. Overall, our research demonstrated, for the first time, that anti-inflammatory active components (triptolide and triptonide) upregulated the expression of IL-37 most likely via activation of the ERKI/2 and p38 MAPK pathways.展开更多
