General tipsFor obtaining a higher solubility, please warm the tube at 37°C and shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.


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.
