investigated their ability to suppress pro-inflammatory signaling in human monocyte (THP-1) and murine macrophage-like (RAW 267.4) cell lines. One of these derivatives, (Z)-2-((5-(hydroxymethyl) furan-2-yl) methylene) benzofuran-3(2H)-one (aurone 1), was found to inhibit LPS-induced secretion of the pro-inflammatory cytokines, tumor-necrosis factor α (TNFα), interleukin 1β (IL-1β), and IL-8 by THP-1 cells
抑制细胞因子的反应经常被证明对许多慢性炎症和自身免疫性疾病具有有希望的治疗作用。但是,与长期使用当前疗法相关的严重副作用,例如过敏反应和中风风险增加,已将注意力集中在靶向调节炎症的细胞内信号传导机制(例如NF-κB)上。我们合成了一系列的非天然金酮衍生物,并研究了它们抑制人类单核细胞(THP-1)和鼠类巨噬细胞样(RAW 267.4)细胞系促炎性信号传导的能力。发现这些衍生物之一,(Z)-2-((5-(羟甲基)呋喃-2-基)亚甲基)苯并呋喃-3(2H)-一(Aurone 1),可抑制LPS诱导的脯氨酸分泌。炎症细胞因子,肿瘤坏死因子α(TNFα),THP-1细胞产生白介素1β(IL-1β)和IL-8。为了研究该机制,我们探讨了金黄色素1对THP-1和RAW264.7中LPS诱导的MAPK和NF-κB信号传导的影响。尽管aurone 1预处理对ERK,JNK或p38 MAPK的磷酸化没有影响
