我们发现,香豆霉素抗生素新生霉素(一种有效的ADP核糖基化抑制剂)可阻止脂多糖(LPS)诱导的人外周血单核细胞分泌肿瘤坏死因子α(TNF-α)、白细胞介素-1(IL-1)、IL-6和IL-10。它与ADP核糖基化的其他抑制剂共享这些精氨酸抑制特性。我们发现新生霉素通过抑制TNF-α mRNA的翻译来阻止TNF-α的产生。新生霉素未降低d-半乳糖胺(GalN)-LPS或GalN-TNF处理小鼠中升高的TNF-α水平;然而,该药物具有保肝特性。新生霉素引起单核细胞表面分子下调,其中CD 14受影响最大。在T和B淋巴细胞上未观察到表面分子表达的减少。与ADP核糖基化的其他抑制剂类似,新生霉素阻止LPS诱导的γ-肌动蛋白的磷酸盐标记。
ABSTRACT We show that the coumeromycin antibiotic novobiocin, a potent inhibitor of ADP ribosylation, prevents lipopolysaccharide (LPS)-induced tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), IL-6, and IL-10 secretion in human peripheral blood mononuclear cells. It shares these cytokine-suppressing properties with other inhibitors of ADP ribosylation. We found that novobiocin prevents TNF-α production by inhibiting translation of the TNF-α mRNA. Elevated TNF-α levels in mice treated withd-galactosamine (GalN)-LPS or GalN-TNF were not reduced by novobiocin; however, the drug exhibited hepatoprotective properties. Novobiocin causes downregulation of the surface molecules on monocytes, among which CD14 was the most affected. The diminished expression of surface molecules was not observed on T and B lymphocytes. Similar to other inhibitors of ADP ribosylation, novobiocin prevents LPS-induced phosphate labelling of γ-actins.
