Cell experiment [1]:

Cell lines

PC12 cells

Preparation method

The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

1–1000 μM; 3h


In PC12 cells, Acetylcysteine (NAC) produced concentration-dependent decreases in DOPAL levels. Co-incubation of NAC (1-10 μM) with selegiline (1 μM) attenuated or prevented the Cys-DA response to selegiline, without interfering with the selegiline-induced decrease in DOPAL production or inhibiting tyrosine hydroxylation.

Animal experiment [2]:

Animal models

the R6/1 transgenic mouse model of Huntington’s disease (HD)

Dosage form

500 mg/kg i.p., 4 weeks


In the R6/1 transgenic mouse model of Huntington’s disease (HD), Acetylcysteine (NAC)-HD mice showed forced-swim test (FST) immobility times intermediate to saline-HD and saline-WT mice. NAC exhibited antidepressant-like effect. HD mice co-administered with CPG (inhibitor of GLT-1) and NAC showed higher immobility times than NAC-HD mice, suggesting that the antidepressant-like effect of NAC is dependent on glutamate transport.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Acetylcysteine is a mucolytic agent which reduces the thickness of the mucus. Acetylcysteine is a ROS inhibitor[1].
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[2]. Acetylcysteine causes dose-dependent reductions in viability in rat and human aortic smooth muscle cells[3]. 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[4].
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[6]. 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[5].
