Acétylcystéine (N-acétyl-L-cystéine) est un agent mucolytique qui réduit l'épaisseur du mucus. Acétylcystéine est un inhibiteur des ROS. Acétylcystéine est un précurseur de la cystéine, prévient la ferroptose induite par l'hémine en neutralisant les lipides toxiques générés par l'activité dépendante de l'arachidonate des 5-lipoxygénases. Acétylcystéine induit l'apoptose cellulaire.

    Wild-type, Prx1KO, and Prx1OE cells are each divided into three groups, which are control groups, groups treated with 100 ng/mL LPS, and groups treated with 100 ng/mL LPS and NAC. Western blot analysis is then performed with antibodies against Bax, Bcl-2, Cyto-c, caspase 3, and GAPDH, and band intensity is measured with densitometry.

    Acetylcysteine purchased from MedChemExpress. Usage Cited in: Sci Rep. 2016 Oct 27;6:35995.  [Abstract]

    Pretreatment of NAC, a free radical scavenger, largely decreases the expression of caspase-3 and almost abolishes the H2O2 induced upregulation of PRX1. Western blot analysis shows the pretreatment of osteoblast cells with E2 partially abrogates the increased PRX1 and caspase-3 expressions induced by H2O2.

    Description

    Acetylcysteine (N-Acetylcysteine) is a mucolytic agent which reduces the thickness of the mucus. Acetylcysteine is a ROS inhibitor[1]. Acetylcysteine is a cysteine precursor, prevents hemin-induced ferroptosis by neutralizing toxic lipids generated by arachidonate-dependent activity of 5-lipoxygenases[5]. Acetylcysteine induces cell apoptosis[2][3]. Acetylcysteine also has anti-influenza virus activities[7].

    IC50 & Target

    Human Endogenous Metabolite

     

    In Vitro

    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].

    In Vivo

    Acetylcysteine (150, 300 mg/kg) treatment significantly reduces liver transaminases in all groups of treatment, mostly in group Acetylcysteine 300 mg/kg. Lung glutathione peroxidase is significantly increases in group Acetylcysteine 300 mg/kg(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].

    Cell Assay
    [2]

    For survival experiments, washed cells are resuspended in RPM1 1640 medium and plated in 0.5 mL at a density of 8-10×105 per well in 24 well plastic culture dishes coated with rat tail collagen. To feed, but to avoid loss of floating cells, fresh medium (0.2 mL) is added to the cultures on days 1, 5, and 10. For experiments involving "primed" PC12 cells, cultures are pretreated for l-2 weeks with NGF in RPM1 1640 medium supplemented with 1% heat-iN-acetylcysteinetivated horse serum. The cells are then washed and passaged into serum-free RPM1 1640 medium.

    Animal Administration
    [6]

    Rats: Rats are randomLy allocated into five groups: sham group (n=5), control group with IIR (n=8) and three groups with IIR who are given Acetylcysteine in different dosages: 150 mg/kg intraperitoneally 5 min before ischemia (n=8, group Acetylcysteine 150), 300 mg/kg i.p 5 min before ischemia (n=7, group Acetylcysteine 300), and 150 mg/kg i.p 5 min before ischemia plus 150 mg/kg 5 min before reperfusion (n=7, group Acetylcysteine 150 + 150). After 4 h of reperfusion, the animals are euthanized by exsanguination from the abdominal aorta.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
