生物活性

Benpyrine is a highly specific and orally active TNF-α inhibitor with a KD value of 82.1 μM. Benpyrine tightly binds to TNF-α and blocks its interaction with TNFR1, with an IC50 value of 0.109 µM. Benpyrine has the potential for TNF-α mediated inflammatory and autoimmune disease research.

体外研究

Benpyrine (5-20 µM; 14 hours; RAW264.7 cells) pretreatment results in a dose-dependent decrease in the phosphorylation of IκBα in RAW264.7 cells (stimulated with 10 ng/mL TNF-α or 1 μg/mL LPS). Benpyrine abolishes the TNF-α-induced nuclear translocation of NF-κB/p65 in RAW264.7 cells.
Benpyrine only blocks cell death induced by TNF-α and YA, and increases the cell survival rate up to 80%. Benpyrine does not obviously affect LA- and YL-induced cytotoxicity in L929 cells.

Western Blot Analysis

Cell Line: RAW264.7 cells
Concentration: 5 µM, 10 µM, 20 µM
Incubation Time: 14 hours
Result: Resulted in a dose-dependent decrease in the phosphorylation of IκBα.
体内研究

Benpyrine (25-50 mg/kg; oral gavage; daily; for 2 weeks; Balb/c mice) treatment significantly relieves the symptoms of collagen-induced arthritis. Benpyrine dose-dependently decreases the levels of proinflammatory cytokines, such as IFN-γ, IL-1β and IL-6, and increases the concentration of the anti-inflammatory cytokine IL-10.
Endotoxemia murine model shows that Benpyrine (25 mg/kg) could attenuate TNF-α-induced inflammation, thereby reducing liver and lung injury.

Animal Model: Balb/c mice (18-20 g) injected with collagen
Dosage: 25 mg/kg, 50 mg/kg
Administration: Oral gavage; daily; for 2 weeks
Result: Relieved the symptoms of collagen-induced arthritis in mice.
