A novel dual regulator of tumor necrosis factor-α and interleukin-10 protects mice from endotoxin-induced shock
2000
Abstract A pyrimidylpiperazine derivative, N -[1-(4-{[4-(pyrimidin-2-yl)piperazin-1-yl]methyl}phenyl)cyclopropyl]acetamide (Y-39041), is a dual cytokine regulator of tumor necrosis factor (TNF)-α and interleukin-10 production. Lipopolysaccharide-induced TNF-α release in BALB/c mice was inhibited by the oral treatment with the compound at 10–100 mg/kg (about 80% suppression) while interleukin-10 release was augmented (about 10-fold increase at 30 mg/kg). In addition, Y-39041 (30 mg/kg, p.o.) completely protected mice from lipopolysaccharide-induced death by the treatment before and after lipopolysaccharide injection. The finding that Y-39041 suppresses TNF-α production and stimulates interleukin-10 production at the same time provides new insights for the treatment of septic shock, rheumatoid arthritis and Crohn's diseases.
