Acetylcysteine (N-acetylcysteine)
别名: N-acetylcysteine 中文名称：乙酰半胱氨酸
Acetylcysteine (N-acetyl-l-cysteine, NAC,N-acetylcysteine)是ROS抑制剂，拮抗多种蛋白酶体抑制剂的活性。它还是肿瘤坏死因子TNF的抑制剂，主要用作祛痰剂，可通过维持或恢复肝脏中谷胱甘肽的浓度来处理扑热息痛(对乙酰氨基酚过量)。Acetylcysteine(N-acetyl-l-cysteine) 通过抑制IκB kinases抑制TNF诱导的NF-κB活化。Acetylcysteine(N-acetyl-l-cysteine) 通过线粒体依赖性途径诱导凋亡并抑制铁死亡和病毒复制。在溶液中不稳定，请现配现用！
