概述

Information

Acetylcysteine (N-acetyl-l-cysteine, NAC) is aROS(reactive oxygen species) inhibitor that antagonizes the activity of proteasome inhibitors. It is also atumor necrosis factor productioninhibitor. Acetylcysteine(N-acetyl-l-cysteine) suppresses TNF-inducedN
In vitro

N-acetylcysteine inhibits activation of c-Jun N-terminal kinase, p38 MAP kinase and redox-sensitive activating protein-1 and nuclear factor kappa B transcription factor activities regulating expression of numerous genes. N-acetylcysteine can also prevent apoptosis and promote cell survival by activating extracellular signal-regulated kinase pathway, a concept useful for treating certain degenerative diseases. N-acetylcysteine directly modifies the activity of several proteins by its reducing activity. N-acetylcysteine prevents apoptotic DNA fragmentation and maintains long-term survival in the absence of other trophic support in serum-deprived PC12 cells. N-acetylcysteine also prevents death of PC12 cells and sympathetic neurons. N-acetylcysteine causes dose-dependent reductions in viability in rat and human aortic smooth muscle cells. N-acetylcysteine activates the Ras-extracellular signal-regulated kinase (ERK) pathway in PC12 cells. N-acetylcysteine protects neuronal cells from death evoked by withdrawal of trophic support. N-acetylcysteine increases nitric oxide (NO) release from protein-bound stores in vascular tissue. N-acetylcysteine pretreatment of PC12 cells interferes with NGF-dependent signaling and neurite outgrowth, and it was suggested that NAC interferes with redox-sensitive steps in the NGF mechanism.

In vivo

N-acetylcysteine improves cognition of 12-month-old SAMP8 mice in both the T-maze footshock avoidance paradigm and the lever press appetitive task without inducing non-specific effects on motor activity, motivation to avoid shock, or body weight.

生化机理

乙酰半胱氨酸（N-acetyl-l-cysteine，NAC）是一种 ROS（活性氧）抑制剂，可拮抗蛋白酶体抑制剂的活性。它还是一种肿瘤坏死因子生成抑制剂。乙酰半胱氨酸（N-乙酰-L-半胱氨酸）通过抑制 IκB 激酶抑制 TNF 诱导的 NF-κB 激活。乙酰半胱氨酸（N-乙酰-L-半胱氨酸）通过线粒体依赖途径诱导细胞凋亡。乙酰半胱氨酸（N-乙酰-L-半胱氨酸）可抑制铁变态反应和病毒复制。
