abstractText | We use the LPS-stimulated macrophage as a model of inflammation to investigate the anti-inflammatory effects of tomatidine and solasodine, whose structures resemble glucocorticoids. We found that tomatidine exhibited a more potent anti-inflammatory effect than solasodine. Tomatidine could decrease inducible nitric oxide synthase and cyclooxygenase-2 expression through suppression of I-kappaBalpha phosphorylation, NF-kappaB nuclear translocation and JNK activation, which in turn inhibits c-jun phosphorylation and Oct-2 expression. Here, we demonstrate that tomatidine acts as an anti-inflammatory agent by blocking NF-kappaB and JNK signaling, and may possibly be developed as a useful agent for the chemoprevention of cancer or inflammatory diseases. |
