This study aimed to investigate the effect of fatty acid-ethanol amine (FA-EA) derivatives (L1–L10) on the mitigation of intracellular lipid accumulation and downregulation of pro-inflammatory cytokines in vitro. First, the series of FA-EA derivatives were synthesized and characterized. Then, their cytotoxic, intracellular lipid accumulation and inhibition of pro-inflammatory cytokines were evaluated
本研究旨在研究脂肪酸-乙醇胺 (FA-EA) 衍生物 ( L1 – L10 ) 对减轻细胞内脂质积累和体外促炎细胞因子下调的影响。首先,合成并表征了 FA-EA 系列衍生物。然后,评估了它们的细胞毒性、细胞内脂质积累和促炎细胞因子的抑制作用。油红O染色实验表明,供试化合物L4、L6、L8、L9、L10可以减少由棕榈酸 (PA) 诱导的细胞内脂质积累。此外,ω-3/ω-6 PUFA-EA 衍生物对脂多糖 (LPS) 刺激的 RAW 264.7 细胞中促炎细胞因子的产生显示出抑制作用。10 μM浓度的ω-3/ω-6 PUFA-EA衍生物可显着降低IL-6、IL-1β和TNF-α的mRNA水平,抑制NO产生,减轻IL-1β蛋白表达。脂多糖 (LPS) 刺激的 RAW 264.7 细胞。这些数据表明,ω-3 PUFA-EA 衍生物可有益于进一步药物开发,以治疗肥胖等慢性低度炎症疾病。
