Reactive oxygen species (ROS)

[体外研究]

N-叔丁基-α-苯基硝酮(PBN)(25-100µM)处理可显著降低2,2'-偶氮双(2-氨基丙烷)二盐酸盐(AAPH)诱导的细胞内ROS累积。N-叔丁基-α-苯基硝基酮也能减弱AAPH诱导的细胞毒性、基质降解和凋亡。N-叔丁基-α-苯基硝基酮抑制AAPH诱导的ERK/MAPK通路激活。N-叔丁基-α-苯基亚硝酮对椎间盘退变(IDD)的研究具有潜在意义[1]。

[体内研究]

N-叔丁基-α-苯基亚硝酮(PBN；100mg/kg；腹腔注射；一天两次；C57Bl/6小鼠)治疗不仅可以消除LPS诱导的脂质过氧化、硝基酪氨酸残留水平和GSH耗竭,还可以降低外部畸形的发生率[2]。动物模型：脂多糖(LPS)诱导C57Bl/6小鼠[2]剂量：100mg/kg给药：腹腔注射；每日2次(妊娠第8天)结果：消除LPS诱导的脂质过氧化、硝基酪氨酸残留和GSH耗竭。
