Acetylcysteine試劑生物活性

NAC(防治)是一種黏液溶解的代理,減少粘液的厚度。NAC是一種活性氧抑制劑[1]。乙酰半cystine是一種半cystine前體,防止hemin-induced ferroptosis通過中和生成有毒的脂質(zhì)arachidonate-dependent 5-lipoxygenases活動[5]。NAC誘發(fā)細(xì)胞凋亡[2][3]。NAC還具有抗流感病毒活動

Acetylcysteine試劑IC₅₀ & Target

Human Endogenous Metabolite

體外研究
(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].

體內(nèi)研究
(In Vivo)

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].
