Abstract:
Discretamine is a tetrahydroprotoberberine alkaloid isolated from Duguetia moricandiana (Annonaceae). In the present study, anti-inflammatory ability of discretamine in a lipopolysaccharide (LPS) stimulated macrophages model was investigated. LPS-induced NO production was reduced by discretamine treatment (100 and 200 μg/mL) around 50%. Furthermore, discretamine (50, 100, and 200 μg/mL) treatment down-regulated pivotal inflammatory cytokines levels, such as IL-6 (74.1, 76.6, and 75.1%, respectively), IL1-β (89.4, 87.4, and 71.8%, respectively), and TNF-α (61, 45.2, and 52.6%, respectively) levels. Also, discretamine did not reduce peritoneal macrophage viability. Besides that, in vivo carrageenan-induced paw edema experiments were also carried out. Discretamine treatment (5, 10, and 20 mg/kg) reduced paw edema up to 6h. Taken together, these data demonstrated that discretamine exerted its anti-inflammatory effect by down-regulation the levels of TNF-α, IL-6, and IL1-β, and by inhibition of NO release.
