Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.67mg/ml Taking the 1 mL working solution as an example, add 50 μL of 33.3 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to make it clear. Volume up to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Acetylcysteine (N-acetyl-l-cysteine, NAC,N-acetylcysteine) is a ROS(reactive oxygen species) inhibitor that antagonizes the activity of proteasome inhibitors. It is also a tumor necrosis factor production inhibitor. Acetylcysteine(N-acetyl-l-cysteine) suppresses TNF-induced NF-κB activation through inhibition of IκB kinases. Acetylcysteine(N-acetyl-l-cysteine) induces apoptosis via the mitochondria-dependent pathway. Acetylcysteine(N-acetyl-l-cysteine) inhibits ferroptosis and virus replication.Solutions are unstable and should be fresh-prepared.
Targets
NF-κB [8] Ferroptosis [9] ROS [6] TNF-α [7]
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. [1]

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. [2]

N-acetylcysteine causes dose-dependent reductions in viability in rat and human aortic smooth muscle cells. [3]

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. [4]
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. [5]
