Acetylcysteine (Synonyms:乙酰半胱氨酸; N-Acetylcysteine; N-Acetyl-L-cysteine; NAC)
目录号 : KM13196 CAS No. : 616-91-1 纯度 : ≥98%

Acetylcysteine (N-Acetylcysteine) 是一种粘液溶解剂 (mucolytic agent),可用于减少粘液的厚度。Acetylcysteine 是一种 ROS 抑制剂。Acetylcysteine 是半胱氨酸前体,通过中和花生四烯酸依赖的5-脂氧合酶活性所产生的毒性脂质来防止血红素诱导的铁中毒 (ferroptosis)。Acetylcysteine 可以诱导细胞凋亡 (apoptosis),并具有抗流感病毒活性。

生物活性

Acetylcysteine (N-Acetylcysteine) is a mucolytic agent which reduces the thickness of the mucus. Acetylcysteine is a ROS inhibitor. Acetylcysteine is a cysteine precursor, prevents hemin-induced ferroptosis by neutralizing toxic lipids generated by arachidonate-dependent activity of 5-lipoxygenases. Acetylcysteine induces cell apoptosis. Acetylcysteine also has anti-influenza virus activities.

体外研究

Acetylcysteine prevents apoptotic DNA fragmentation and maintains long-term survival in the absence of other trophic support in serum-deprived PC12 cells. Acetylcysteine also prevents death of PC12 cells and sympathetic neurons.
Acetylcysteine causes dose-dependent reductions in viability in rat and human aortic smooth muscle cells.
Acetylcysteine activates the Ras-extracellular signal-regulated kinase (ERK) pathway in PC12 cells. Acetylcysteine protects neuronal cells from death evoked by withdrawal of trophic support. Acetylcysteine increases nitric oxide (NO) release from protein-bound stores in vascular tissue. Acetylcysteine pretreatment of PC12 cells interferes with NGF-dependent signaling and neurite outgrowth, and it is suggested that Acetylcysteine interferes with redox-sensitive steps in the NGF mechanism.

体内研究

Acetylcysteine (150, 300 mg/kg) treatment significantly reduces liver transaminases in all groups of treatment, mostly in group Acetylcysteine 300. Lung glutathione peroxidase is significantly increases in group Acetylcysteine 300 (P=0.04), while the other oxidation biomarkers show no significant differences.
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.
