JunB forms the majority of the AP-1 complex and is a target for redox regulation by receptor tyrosine kinase and G protein-coupled receptor agonists in smooth muscle cells. (1/2675)

To understand the role of redox-sensitive mechanisms in vascular smooth muscle cell (VSMC) growth, we have studied the effect of N-acetylcysteine (NAC), a thiol antioxidant, and diphenyleneiodonium (DPI), a potent NADH/NADPH oxidase inhibitor, on serum-, platelet-derived growth factor BB-, and thrombin-induced ERK2, JNK1, and p38 mitogen-activated protein (MAP) kinase activation; c-Fos, c-Jun, and JunB expression; and DNA synthesis. Both NAC and DPI completely inhibited agonist-induced AP-1 activity and DNA synthesis in VSMC. On the contrary, these compounds had differential effects on agonist-induced ERK2, JNK1, and p38 MAP kinase activation and c-Fos, c-Jun, and JunB expression. NAC inhibited agonist-induced ERK2, JNK1, and p38 MAP kinase activation and c-Fos, c-Jun, and JunB expression except for platelet-derived growth factor BB-induced ERK2 activation. In contrast, DPI only inhibited agonist-induced p38 MAP kinase activation and c-Fos and JunB expression. Antibody supershift assays indicated the presence of c-Fos and JunB in the AP-1 complex formed in response to all three agonists. In addition, cotransfection of VSMC with expression plasmids for c-Fos and members of the Jun family along with the AP-1-dependent reporter gene revealed that AP-1 with c-Fos and JunB composition exhibited a higher transactivating activity than AP-1 with other compositions tested. All three agonists significantly stimulated reactive oxygen species production, and this effect was inhibited by both NAC and DPI. Together, these results strongly suggest a role for redox-sensitive mechanisms in agonist-induced ERK2, JNK1, and p38 MAP kinase activation; c-Fos, c-Jun, and JunB expression; AP-1 activity; and DNA synthesis in VSMC. These results also suggest a role for NADH/NADPH oxidase activity in some subset of early signaling events such as p38 MAP kinase activation and c-Fos and JunB induction, which appear to be important in agonist-induced AP-1 activity and DNA synthesis in VSMC.  (+info)

N,N'-Diacetyl-L-cystine-the disulfide dimer of N-acetylcysteine-is a potent modulator of contact sensitivity/delayed type hypersensitivity reactions in rodents. (2/2675)

Oral N-acetyl-L-cysteine (NAC) is used clinically for treatment of chronic obstructive pulmonary disease. NAC is easily oxidized to its disulfide. We show here that N,N'-diacetyl-L-cystine (DiNAC) is a potent modulator of contact sensitivity (CS)/delayed type hypersensitivity (DTH) reactions in rodents. Oral treatment of BALB/c mice with 0.003 to 30 micromol/kg DiNAC leads to enhancement of a CS reaction to oxazolone; DiNAC is 100 to 1000 times more potent than NAC in this respect, indicating that it does not act as a prodrug of NAC. Structure-activity studies suggest that a stereochemically-defined disulfide element is needed for activity. The DiNAC-induced enhancement of the CS reaction is counteracted by simultaneous NAC-treatment; in contrast, the CS reaction is even more enhanced in animals treated with DiNAC together with the glutathione-depleting agent buthionine sulfoximine. These data suggest that DiNAC acts via redox processes. Immunohistochemically, ear specimens from oxazolone-sensitized and -challenged BALB/c mice treated with DiNAC display increased numbers of CD8(+) cells. DiNAC treatment augments the CS reaction also when fluorescein isothiocyanate is used as a sensitizer in BALB/c mice; this is a purported TH2 type of response. However, when dinitrofluorobenzene is used as a sensitizer, inducing a purported TH1 type of response, DiNAC treatment reduces the reaction. Treatment with DiNAC also reduces a DTH footpad-swelling reaction to methylated BSA. Collectively, these data indicate that DiNAC in vivo acts as a potent and effective immunomodulator that can either enhance or reduce the CS or DTH response depending on the experimental conditions.  (+info)

Protective alterations in phase 1 and 2 metabolism of aflatoxin B1 by oltipraz in residents of Qidong, People's Republic of China. (3/2675)

BACKGROUND: Residents of Qidong, People's Republic of China, are at high risk for development of hepatocellular carcinoma, in part due to consumption of foods contaminated with aflatoxins, which require metabolic activation to become carcinogenic. In a randomized, placebo-controlled, double-blind phase IIa chemoprevention trial, we tested oltipraz, an antischistosomal drug that has been shown to be a potent and effective inhibitor of aflatoxin-induced hepatocarcinogenesis in animal models. METHODS: In 1995, 234 adults from Qidong were enrolled. Healthy eligible individuals were randomly assigned to receive by mouth 125 mg oltipraz daily, 500 mg oltipraz weekly, or a placebo. Sequential immunoaffinity chromatography and liquid chromatography coupled to mass spectrometry or to fluorescence detection were used to identify and quantify phase 1 and phase 2 metabolites of aflatoxin B1 in the urine of study participants. Reported P values are two-sided. RESULTS: One month of weekly administration of 500 mg oltipraz led to a 51% decrease in median levels of the phase 1 metabolite aflatoxin M1 excreted in urine compared with administration of a placebo (P = .030), but it had no effect on levels of a phase 2 metabolite, aflatoxin-mercapturic acid (P = .871). By contrast, daily intervention with 125 mg oltipraz led to a 2.6-fold increase in median aflatoxin-mercapturic acid excretion (P = .017) but had no effect on excreted aflatoxin M1 levels (P = .682). CONCLUSIONS: Intermittent, high-dose oltipraz inhibited phase 1 activation of aflatoxins, and sustained low-dose oltipraz increased phase 2 conjugation of aflatoxin, yielding higher levels of aflatoxin-mercapturic acid. While both mechanisms can contribute to protection, this study highlights the feasibility of inducing phase 2 enzymes as a chemopreventive strategy in humans.  (+info)

Proteasome-dependent degradation of the human estrogen receptor. (4/2675)

In eukaryotic cells, the ubiquitin-proteasome pathway is the major mechanism for the targeted degradation of proteins with short half-lives. The covalent attachment of ubiquitin to lysine residues of targeted proteins is a signal for the recognition and rapid degradation by the proteasome, a large multi-subunit protease. In this report, we demonstrate that the human estrogen receptor (ER) protein is rapidly degraded in mammalian cells in an estradiol-dependent manner. The treatment of mammalian cells with the proteasome inhibitor MG132 inhibits activity of the proteasome and blocks ER degradation, suggesting that ER protein is turned over through the ubiquitin-proteasome pathway. In addition, we show that in vitro ER degradation depends on ubiquitin-activating E1 enzyme (UBA) and ubiquitin-conjugating E2 enzymes (UBCs), and the proteasome inhibitors MG132 and lactacystin block ER protein degradation in vitro. Furthermore, the UBA/UBCs and proteasome inhibitors promote the accumulation of higher molecular weight forms of ER. The UBA and UBCs, which promote ER degradation in vitro, have no significant effect on human progesterone receptor and human thyroid hormone receptor beta proteins.  (+info)

Critical role of glass fiber length in TNF-alpha production and transcription factor activation in macrophages. (5/2675)

Recent studies have demonstrated that dielectrophoresis is an efficient method for the separation of fibers according to fiber length. This method allows the investigation of fiber-cell interactions with fiber samples of the same composition but of different lengths. In the present study, we analyzed the effects of length on the interaction between glass fibers and macrophages by focusing on production of the inflammatory cytokine tumor necrosis factor (TNF)-alpha in a mouse macrophage cell line (RAW 264.7). The underlying molecular mechanisms controlling TNF-alpha production were investigated at the gene transcription level. The results show that glass fibers induced TNF-alpha production in macrophages and that this induction was associated with activation of the gene promoter. Activation of the transcription factor nuclear factor (NF)-kappaB was responsible for this induced promoter activity. The inhibition of both TNF-alpha production and NF-kappaB activation by N-acetyl-L-cysteine, an antioxidant, indicates that generation of oxidants may contribute to the induction of this cytokine and activation of this transcription factor by glass fibers. Long fibers (17 micrometer) were significantly more potent than short fibers (7 micrometer) in inducing NF-kappaB activation, the gene promoter activity, and the production of TNF-alpha. This fiber length-dependent difference in the stimulatory potency correlated with the fact that macrophages were able to completely engulf short glass fibers, whereas phagocytosis of long glass fibers was incomplete. These results suggest that fiber length plays a critical role in the potential pathogenicity of glass fibers.  (+info)

Evidence for proteasome involvement in polyglutamine disease: localization to nuclear inclusions in SCA3/MJD and suppression of polyglutamine aggregation in vitro. (6/2675)

Spinocerebellar ataxia type 3, also known as Machado-Joseph disease (SCA3/MJD), is one of at least eight inherited neurodegenerative diseases caused by expansion of a polyglutamine tract in the disease protein. Here we present two lines of evidence implicating the ubiquitin-proteasome pathway in SCA3/MJD pathogenesis. First, studies of both human disease tissue and in vitro models showed redistribution of the 26S proteasome complex into polyglutamine aggregates. In neurons from SCA3/MJD brain, the proteasome localized to intranuclear inclusions containing the mutant protein, ataxin-3. In transfected cells, the proteasome redistributed into inclusions formed by three expanded polyglutamine proteins: a pathologic ataxin-3 fragment, full-length mutant ataxin-3 and an unrelated GFP-polyglutamine fusion protein. Inclusion formation by the full-length mutant ataxin-3 required nuclear localization of the protein and occurred within specific subnuclear structures recently implicated in the regulation of cell death, promyelocytic leukemia antigen oncogenic domains. In a second set of experiments, inhibitors of the proteasome caused a repeat length-dependent increase in aggregate formation, implying that the proteasome plays a direct role in suppressing polyglutamine aggregation in disease. These results support a central role for protein misfolding in the pathogenesis of SCA3/MJD and suggest that modulating proteasome activity is a potential approach to altering the progression of this and other polyglutamine diseases.  (+info)

N-acetyl-L-cysteine inhibits primary human T cell responses at the dendritic cell level: association with NF-kappaB inhibition. (7/2675)

N-acetyl-L-cysteine (NAC) is an antioxidant molecule endowed with immunomodulatory properties. To investigate the effect of NAC on the induction phase of T cell responses, we analyzed its action on human dendritic cells (DC) derived from adherent PBMC cultured with IL-4 and granulocyte-macrophage CSF. We first found that NAC inhibited the constitutive as well as the LPS-induced activity of the transcription factor NF-kappaB. In parallel, NAC was shown to down-regulate the production of cytokines by DC as well as their surface expression of HLA-DR, CD86 (B7-2), and CD40 molecules both at the basal state and upon LPS activation. NAC also inhibited DC responses induced by CD40 engagement. The inhibitory effects of NAC were not due to nonspecific toxicity as neither the viability of DC nor their mannose receptor-mediated endocytosis were modified by NAC. Finally, we found that the addition of NAC to MLR between naive T cells and allogeneic DC resulted in a profound inhibition of alloreactive responses, which could be attributed to a defect of DC as APC-independent T cell responses were not inhibited by NAC. Altogether, our results suggest that NAC might impair the generation of primary immune responses in humans through its inhibitory action on DC.  (+info)

Modulation of proteasomal activity required for the generation of a cytotoxic T lymphocyte-defined peptide derived from the tumor antigen MAGE-3. (8/2675)

We have analyzed the presentation of human histocompatability leukocyte antigen-A*0201-associated tumor peptide antigen MAGE-3271-279 by melanoma cells. We show that specific cytotoxic T lymphocyte (CTL)-recognizing cells transfected with a minigene encoding the preprocessed fragment MAGE-3271-279 failed to recognize cells expressing the full length MAGE-3 protein. Digestion of synthetic peptides extended at the NH2 or COOH terminus of MAGE-3271-279 with purified human proteasome revealed that the generation of the COOH terminus of the antigenic peptide was impaired. Surprisingly, addition of lactacystin to purified proteasome, though partially inhibitory, resulted in the generation of the antigenic peptide. Furthermore, treatment of melanoma cells expressing the MAGE-3 protein with lactacystin resulted in efficient lysis by MAGE-3271-279-specific CTL. We therefore postulate that the generation of antigenic peptides by the proteasome in cells can be modulated by the selective inhibition of certain of its enzymaticactivities.  (+info)

Oxidative stress is implicated in the pathogenesis of a number of neurodegenerative diseases such as Parkinsons disease (PD). Further, levels of glutathione (GSH), a prevalent endogenous antioxidant, are decreased in the postmortem substantia nigra (SN) of individuals with PD, indicating increased oxidative stress, although this has yet not been confirmed in vivo. Increases in intracellular oxidative stress have also been observed in primary fibroblast cultures obtained from patients with GD, where enzyme replacement therapy resulted in increases in total GSH. The hypothesis that oxidative stress plays a key role in the neurodegeneration associated with PD suggests that antioxidants may be useful in altering disease progression.. N-acetylcysteine (NAC) is a well-known antioxidant that is thought to act both as a free radical scavenger and as a cysteine donor for the synthesis of GSH. NAC may be beneficial in the treatment of PD and GD. Magnetic resonance spectroscopy (MRS) methods may be able ...

The tissue death resulting from ischemic changes is a complex process that involves a series of cell events. The interruption of the bloodstream compromise the oxygen supply, nutrients and metabolites needed for the physiological maintenance of muscle tissue. Among the causes of tissue ischemia we highlight arterial thrombosis caused by atherosclerotic disease, responsible for the cardiac, renal, cerebral and peripheral ischemic changes. The tissue ischemia caused by atherosclerotic disease has great incidence on the current Western population, being responsible for high rates of morbidity and mortality. Given the current situation, We sought to evaluate the role of N-acetylcysteine treatment in animals submitted to the lower members ischemia model. To evaluate the effect of Nac, 21 male Wistar rats weighing 250-300 g were used and they were divided into three groups of 7 animals: (1) Sham, (2) Ischemia, (3) NAC-treated ischemia. The animals were submitted to the process of ischemia induction of ...
NAC (N-Acetyl-l-Cysteine) Powerful free radical scavenger N-Acetyl-l-Cysteine (NAC) is a derivative of the dietary amino acid l-cysteine. NAC has a high affinity for lung tissue, which it supports through mucolytic and antioxidant action. By disrupting disulfide bonds, NAC thins mucus. It is a powerful free radical scavenger and thus supports the bodys natural defense system. NAC supports tissue levels of glutathione, a key component of the antioxidant defense system. It also has the ability to help chelate heavy metals. NAC provides powerful nutritional support to cells as an antioxidant and specifically supports healthy lung functioning through its mucolytic capability.

CONCLUSIONS These findings suggest ...
One hundred cases of severe paracetamol poisoning were treated with intravenous N-acetylcysteine (acetyl-cysteine). There was virtually complete protection against liver damage in 40 patients treated within eight hours after ingestion (mean maximum serum alanine transaminase activity 27 IU/1). Only one out of 62 patients treated within 10 hours developed severe liver damage compared with 33 out of 57 patients (58%) studied retrospectively who received supportive treatment alone. Early treatment and acetylcysteine also prevented renal impairment and death. The critical ingestion-treatment interval for complete protection against severe liver damage was eight hours. Efficacy diminished progressively thereafter, and treatment after 15 hours was completely ineffective. Intravenous acetylcysteine was more effective than cysteamine and methionine and noticeably free of adverse effects. It is the treatment of choice for paracetamol poisoning.
Since oral administration of acetylcysteine may result in vomiting or aggravate vomiting associated with paracetamol overdosage, patients at risk of gastric hemorrhage should be evaluated with regard to the relative risks of upper gastrointestinal hemorrhage and paracetamol-induced hepatotoxicity and treatment with acetylcysteine given accordingly.. Asthmatic patients receiving acetylcysteine should be observed closely during such therapy; if bronchospasm occurs, a bronchodilator should be given by nebulization. If bronchospasm progresses, acetylcysteine should be discontinued immediately.. An increased volume of liquefied bronchial secretions may develop after administration of acetylcysteine. If cough is inadequate to maintain an open airway during acetylcysteine therapy, mechanical suction or endotracheal aspiration should be instituted.. Stacytine 200 CAP can be used for pregnant and nursing women.. Patients should be aware of how they react to Stacytine 200 CAP before driving or operating ...

For over thirty years, a protected, minimal effort compound known as N-acetyl cysreine (NAC) has given help to many individuals from the wheezing, thick mucus related to flu or cold and wheezing. Obviously, pharmaceutical organizations co-selected it for benefit by joining it into different licensed medications. The pitiful outcome is that most specialists or health experts have never known about it. Indeed, even many specialists stay uninformed of its potential part as an amazing guard against some of todays most general health threats. Below are some amazing benefits NAC can provide a human body. N-acetyl cysteine comes from the amino acid L-cysteine. Amino acids are the building blocks of proteins. N-acetyl cysteine has many uses as medicine.. N-acetyl cysteine is used to counteract acetaminophen (Tylenol) and carbon monoxide poisoning. It is also used for chest pain (unstable angina), bile duct blockage in infants, amyotrophic lateral sclerosis (ALS, Lou Gehrigs disease), Alzheimers ...
NAC (N-Acetyl-l-Cysteine) Powerful free radical scavenger N-Acetyl-l-Cysteine (NAC) is a derivative of the dietary amino acid l-cysteine. NAC has a high affinity for lung tissue, which it supports through mucolytic and antioxidant action. By disrupting disulfide bonds, NAC thins mucus. It is a powerful free radical scavenger and thus supports the bodys natural defense system. NAC supports tissue levels of glutathione, a key component of the antioxidant defense system. It also has the ability to help chelate heavy metals. NAC provides powerful nutritional support to cells as an antioxidant and specifically supports healthy lung functioning through its mucolytic capability. Supplement Facts: Amount Per Serving each vegetable capsule contains: n-acetyl-l-cysteine (free- form) 900 mg. vitamin C (as ascorbyl palmitate) 10 mg. Directions: 12 capsules per day, between meals.

N-acetylcysteine (NAC) is a sulfhydryl donor antioxidant that contributes to the regeneration of glutathione (GSH) and also scavengers via a direct reaction with free oxygen radicals. Recently, we observed a modulatory role of NAC on GSH-depleted dorsal root ganglion (DRG) cells in rats. NAC may have a protective role on oxidative stress and calcium influx through regulation of the TRPM2 channel in diabetic neurons. Therefore, we investigated the effects of NAC on DRG TRPM2 channel currents and brain oxidative stress in streptozotocin (STZ)-induced diabetic rats. Thirty-six rats divided into four groups: control, STZ, NAC and STZ + NAC. Diabetes was induced in the STZ and STZ + NAC groups by intraperitoneal STZ (65 mg/kg) administration. After the induction of diabetes, rats in the NAC and STZ + NAC groups received NAC (150 mg/kg) via gastric gavage. After 2 weeks, DRG neurons and the brain cortex were freshly isolated from rats. In whole-cell patch clamp experiments, TRPM2 currents in the DRG ...

Background: Contrast nephropathy (CIN) post percutaneous coronary intervention (PCI) increases adverse clinical outcomes. We examine and compare the risks and clinical predictors of CIN among patients who undergo primary versus elective PCI and the effectiveness of prophylactic treatments.. Methods: A cohort of 8798 patients who underwent PCI from May 1996 to April 2008 were enrolled. We divided patients into 3 groups(Grp). A: STEMI patient undergoing primary PCI. B: NSTEMI patients undergoing early elective PCI. C: stable patients without myocardial infarction(MI) undergoing elective PCI. Prophylactic saline hydration and oral N-acetylcysteine (NAC) treatment were given to Grp B and C if they have baseline renal impairment (glomerular filtration rate, GFR ≤60ml/min/1.73m2). Grp A patients were unable to receive pre-PCI prophylaxis due to emergency situation. The occurrence of CIN and mortality were compared among 3 grps.. Results: Mean age was 57.4±11.1 years. 3146(35.9%) were diabetics. CIN ...

e-mail: [email protected] Received: 30 May 2020; Accepted: 17 December 2021. This study aimed to consider the lead-induced oxidative damage of the kidney of male rats and the role of antioxidant N-acetylcysteine (NAC) in preserving cells against Pb toxicity. Rats were randomly divided into five groups including G1 (control), G2 (single 70 mg/kg dose of Pb), G3 (continuous daily 2 mg/kg dosing of Pb for 4 weeks), G4 (single dose of Pb + 50 mg/kg NAC), and G5 (continuous daily dosing of Pb + 50 mg/kg NAC). The level of malonic dialdehyde (MDA) and total antioxidant capacity were measured spectrophotometrically.The level of Pb in serum and kidney tissue was measured by atomic absorption spectroscopy. Expression of Bax and Bcl2 genes was estimated using RT-PCR. It was shown that single and continuous exposure to Pb caused a considerable increase of Pb content in serum and kidney tissue of rats in G2 and G3 groups compared to other groups. NAC treatment significantly improved TAC values ...

Epidemiological studies have pointed to fatty acid mono- and diesters of 3-(N-phenylamino)propane-1,2-diol (PAP) as the biomarkers of the toxic oil batches that caused toxic oil syndrome (TOS), an intoxication episode that occurred in Spain in 1981, causing over 400 deaths and affecting more than 20000 people. The biotransformation of PAP administered intraperitoneally to two mouse strains produced potentially toxic metabolites. The identification of 3-(4-hydroxyphenylamino)propane-1,2-diol among those metabolites was important because the compound can generate the quinoneimine intermediate 2. The potential toxicity of quinoneimines has been attributed primarily to their electrophilic character. Accordingly, the reactions of 2 with N-acetylcysteine, N-acetylcysteine methyl ester, and GSH were investigated. Quinoneimine 2 reacts with the N-acetylcysteine methyl ester to give the expected conjugate as a major product, accompanied by the corresponding bis and tris adducts. The monoadduct, when ...
N-acetylcysteine resulted in improved fat graft retention, with 46% take in NAC animals, compared to 17% in controls (p=0.027) (Figure 1). Explanted grafts from the NAC group were significantly larger (46 vs. 8 milligrams, p,0.01) and had a 133% higher mean adipocyte density on histology (p,0.0001) than controls (Figure 2). No increase in vascularity was observed on histology. FACS analysis demonstrated that NAC protected ADSCs from oxidative stress in a dose-dependent manner. Combined exposure to both NAC and hydrogen peroxide led to a 200-fold increase in ADSC proliferation, significantly higher than with either agent alone. NAC significantly decreased the differentiation of pre-adipocyte cells into adipocytes compared to control (p,0.05 ...

The influence of oral N-acetylcysteine on the exacerbation rate in patients with chronic bronchitis and severe airways obstruction has been studied. Two hundred and forty four patients entered the study during October and November 1983 and took placebo sachets for a run in month. One hundred and eighty one who completed this month satisfactorily were randomised to receive either active (acetylcysteine 200 mg three times a day) or matching placebo sachets for five months in a double blind parallel group study. The two groups were well matched. Patients kept detailed daily symptom diaries and were assessed monthly. At the end of the five months study the outcome in the group taking acetylcysteine appeared a little better, but the differences did not reach conventional levels of statistical significance for the mean (SD) number of exacerbations (2.1 (0.2) for acetylcysteine, 2.6 (0.2) for placebo; p = 0.08); total days taking an antibiotic (13.5 (1.7), 18.0 (2.8); p = 0.17); total days spent in ...

The objective of present study was to investigate the effects of aqueous garlic extracts, vitamin E and N-acetylcysteine on lead-induced lipid peroxidation, changes in antioxidant defense system and semen quality in the rat testes. Twenty-five male rats were divided into five groups. Animals within different treatment groups were maintained on their respective diets for 35 days as follows: group 1 rats served as control and received water and standard pellets as food ad libitum; group 2 received lead acetate by gavage (1000 ppm); group 3 was treated with A. sativum extract (400 mg kg-1, by gavage) plus lead acetate (1000 ppm); group 4 was treated orally with vitamin E (300 mg of alpha-tocopherol per kg of chow) plus lead acetate (1000 ppm); group 5 was treated orally with N-acetylcysteine (800 ppm)plus lead acetate (1000 ppm). The weights of testes, epididymis, epididymal sperm count, viable and motile sperms decreased significantly (p | 0.05) in lead-exposed rats. However treatment with vitamin E and
Systemic inflammatory response syndrome (SIRS) is a complex response to an insult such as major surgery or trauma. It is called sepsis syndrome, or simply sepsis, when infection is present. The generalized inflammatory reaction involves activation of leukocytes and endothelial cells and the release of inflammatory mediators and toxic oxygen free radicals. Diffuse microthrombosis can result in localized tissue perfusion abnormalities and low oxygenation (hypoxia). Both SIRS and sepsis can be difficult to treat and are major causes of multiple organ failure and the death of patients in the intensive care unit. SIRS and sepsis both lead to a drop in the level of antioxidants normally present in the body.. N-acetylcysteine is an antioxidant with strong anti-inflammatory effects that is used in treating endotoxaemia and overdoses of acetaminophen. This Cochrane review of 41 randomized controlled trials with 2768 critically ill adult patients found no evidence to support the theory that ...
We report that N-acetyl-L-cysteine (NAC) treatment blocked induction of TNF-α, IL-1β, IFN-γ and iNOS in the CNS and attenuated clinical disease in the myelin basic protein induced model of experimental allergic encephalomyelitis (EAE) in Lewis rats. Infiltration of mononuclear cells into the CNS and induction of inflammatory cytokines and iNOS in multiple sclerosis (MS) and EAE have been implicated in subsequent disease progression and pathogenesis. To understand the mechanism of efficacy of NAC against EAE, we examined its effect on the production of cytokines and the infiltration of inflammatory cells into the CNS. NAC treatment attenuated the transmigration of mononuclear cells thereby lessening the neuroinflammatory disease. Splenocytes from NAC-treated EAE animals showed reduced IFN-γ production, a Th1 cytokine and increased IL-10 production, an anti-inflammatory cytokine. Further, splenocytes from NAC-treated EAE animals also showed decreased nitrite production when stimulated in vitro by LPS.

OBJECTIVES. The effects of 3, 10 and 20% concentrations of acetylcysteine on corneal wound healing in dogs were evaluated. Corneal ulcers induced surgically, up to the depth of the anterior third of the stroma. It was created in both eyes of 18 dogs. One of the eyes was treated topically whit 0.9% NaCl Solution 3 times a day. The contralateral eye (the other one eye) was treated topically by Acetylcysteine 3%, 10% and 20% concentration in each 6 cases separately. Corneal ulcers measured by Fluorescein -staining every day. The mean time of healing in 3% group was significantly different of control eyes (6.17 ± 1.94 days). It was 7.19 ± 0.75 days in 20% group and 7±2 days in 10% group. The last two group were not significantly different from control (9.67 ± 3.01 days and 8.17 ± 3.60 days) respectively. MATERIALS. Dogs: 18 dogs of mixed breed both sexes (8 month to 5 years old) with normal eye examinations were selected. They were housed under lighting controlled at a dim level for comfort. ...
Background. Glutathione (GSH) acts as a free radical scavenger that may be helpful in preventing reperfusion injury. N-acetylcysteine (NAC) replenishes GSH stores. The aims of this study were to evaluate the efficacy of NAC in improving liver graft performance and reducing the incidence of post-operative acute kidney injury (AKI).. Methods. Our study was a randomized, double-blind, placebo-controlled trial of 100 patients; 50 received placebo and 50 received a loading dose of 140 mg/kg of intravenous (IV) NAC over 1 h followed by 70 mg/kg IV repeated every 4 h for a total of 12 doses. Both groups were followed up for 1 year post-orthotopic liver transplant (OLT). We recorded liver function tests, renal function tests, graft survival, patient survival, plasma GSH and duration of hospital and ICU stay. In addition to serum creatinine (SCr) levels, we analysed cystatin C and beta-trace as independent measures of glomerular filtration. All clinical data were recorded daily for the first week after ...

N2 - Background: Fracture healing in alcoholics is delayed and often associated with infections resulting in prolonged rehabilitation. It has been reported that binge drinking of alcohol increases oxidative stress and delays fracture healing in rats, which is prevented by treatment with the antioxidant n-acetyl cysteine (NAC). Oxidative stress is a significant factor in pathologies of various organs resulting from chronic alcoholism. Therefore, we hypothesize that treatment with NAC reduces oxidative stress and restores fracture healing in chronic alcoholics. Methods: Rats (10 months old) were pair-fed the Lieber-DeCarli ethanol (EtOH) diet or ...
BACKGROUND In retinitis pigmentosa (RP), rod photoreceptors degenerate from 1 of many mutations, after which cones are compromised by oxidative stress. N-acetylcysteine (NAC) reduces oxidative damage and increases cone function/survival in RP models. We tested the safety, tolerability, and visual function effects of oral NAC in RP patients.METHODS Subjects (n = 10 per cohort) received 600 mg (cohort 1), 1200 mg (cohort 2), or 1800 mg (cohort 3) NAC bid for 12 weeks and then tid for 12 weeks. Best-corrected visual acuity (BCVA), macular sensitivity, ellipsoid zone (EZ) width, and aqueous NAC were measured. Linear mixed-effects models were used to estimate the rates of changes during the treatment period.RESULTS There were 9 drug-related gastrointestinal adverse events that resolved spontaneously or with dose reduction (maximum tolerated dose 1800 mg bid). During the 24-week treatment period, mean BCVA significantly improved at 0.4 (95% CI: 0.2-0.6, P , 0.001), 0.5 (95% CI: 0.3-0.7, P , 0.001), ...
Regular nebulization proved to be no more effective than nebulization on demand in a randomized trial involving critically ill patients receiving invasive ventilation, researchers reported.. Among ICU patients expected to need invasive ventilation for at least 24 hours, scheduled nebulization four times a day involving acetylcysteine with salbutamol did not result in fewer ventilator-free days, compared with a nebulization schedule based on clinical indications.. The study findings were presented at the Society for Critical Care Medicines annual meeting, and published simultaneously in JAMA.. The studys principal researcher, Frederique Paulus, PhD, of the University of Amsterdam, told MedPage Today that the study did not address whether nebulization is the most effective therapeutic strategy for clearing mucus and clear secretions from the airway of patients who are on mechanical ventilation.. It is possible that other treatments, including less-invasive interventions such as moving the ...

Background Liver cancer is one of the most common malignancies in the world and at the moment, there is no drug intervention effective for the treatment of liver tumours. Investigate the effect of N-acetylcysteine (NAC), which has been studied for its antitumoural properties, on the toxicity of hepatocarcinoma (HCC) cells in vitro when used with the drug interferon alpha-2A (IFN), which is used clinically to treat HCC. Results NAC, IFN and NAC plus IFN reduced cell viability, as determined by MTT assay. More importantly, NAC potentiates the cytotoxic effect of IFN, with the best response achieved with 10 mM of NAC and 2.5 x 104 of IFN. These results were confirmed by Annexin/PI staining through flow cytometry and morphologic analyses. Co-treatment reduced the expression of the nuclear transcription factor kappa-B (NF-kB). In a similar way to NAC, RNAi against p65 potentiated the toxic effect of IFN, suggesting that, indeed, NAC may be enhancing the effect of IFN through inhibition of NF-kB.

Parkinsons disease (PD) is associated with oxidative stress and decreased nigral glutathione (GSH), suggesting that therapies that boost GSH may have a disease-modifying effect. Intravenous administration of a high dose of N-acetylcysteine (NAC), a well-known antioxidant and GSH precursor, increases blood and brain GSH in individuals with PD and with Gaucher disease and in healthy controls. To characterize the pharmacokinetics of repeated high oral doses of NAC and their effect on brain and blood oxidative stress measures, we conducted a 4-week open-label prospective study of oral NAC in individuals with PD (n = 5) and in healthy controls (n = 3 ...
Antiviral Use of the Amino Acid NAC, N-acetyl-L-cysteine: VIDEO review 1 hour 42 minutes (2019): Personal note from Dr Vasquez: I had studied nutrition for at least 25 years and had written my first antiviral nutrition protocol in 2009 and the developed form of that work in 2014 as Antiviral Nutrition; as such, I did not expect to find so much rich information when I began to review the data on the amino acid NAC, the acetylated form of L-cysteine. In truth, I was amazed at the strength and depth of the research on this topic, and I was likewise dumbfounded that this powerful train of therapy was derailed almost as soon as it had been initially validated, at a time that coinsided with the introduction of a multibillion-dollar market for new antiviral drugs.

N-acetylcysteine (NAC) is described as having mucolytic and antioxidant properties. It is widely prescribed for patients with chronic obstructive pulmonary disease (COPD), particularly for those who have accompanying symptoms of chronic cough and sputum production. Randomized, placebo controlled indicate that it is safe and that it may have some clinical benefit when used at relatively low doses. It is postulated that substantially higher doses of NAC will be well-tolerated and will provide better symptom control while also decreasing blood makers of oxidant stress and inflammation ...

The antioxidant NAC (N-acetylcysteine) for glutathione and beyond. Learn how it modulates brain health, its additonal uses, safety, and considerations.
It isnt a herbal formulation but yes, some people were trying Neuropathy Rx because an NF patient reported a significant reduction in one of his tumors shortly after starting the product. In fact, that gentleman spoke at a meeting hosted by one of the NF Inc groups. The idea is that one of the ingredients, N-acetylcysteine or NAC, may have an effect on the RAS pathway which is implicated in NF tumors. Most were trying it for that reason not specifically for pain. A few people did report that they had increased pain in a tumor after beginning the supplements but this seems to have been temporary. I dont personally know of anyone who had drastic tumor shrinkage but last I heard Dr. Pawl was hoping to get a clinical trial going. I did hear a few people say that they felt more focused and had an improved sense of well-being while on the supplement. Interestingly, other NF patients have tried glutathione products such as whey protein (NAC is the precursor to glutathione) and some of them also ...

... , also known as ubiquinone, ubidecarenone, coenzyme Q, and abbreviated at times to CoQ10 /ˌkoʊˌkjuːˈtɛn/, CoQ, or Q10 is a coenzyme that is ubiquitous in animals and most bacteria (hence the name ubiquinone). It is a 1,4-benzoquinone, where Q refers to the quinone chemical group and 10 refers to the number of isoprenyl chemical subunits in its tail. This fat-soluble substance, which resembles a vitamin, is present in all respiring eukaryotic cells, primarily in the mitochondria. It is a component of the electron transport chain and participates in aerobic cellular respiration, which generates energy in the form of ATP. Ninety-five percent of the human body's energy is generated this way.[1][2] Therefore, those organs with the highest energy requirements-such as the heart, liver, and kidney-have the highest CoQ10 concentrations.[3][4][5] There are three redox states of CoQ10: fully oxidized (ubiquinone), semiquinone (ubisemiquinone), and fully reduced (ubiquinol). The capacity ...
... is capable of killing a variety of human cancer cells in vitro while leaving healthy cells unharmed.[9] While apoptosis requires between 16 and 24 hours, oleocanthal operated within 30 minutes to one hour. Oleocanthal pierces cancer cells' lysosomes, the containers that store the cell's waste products, releasing enzymes that kill the cell. In healthy cells, the application of oleocanthal caused a temporary halt in their life cycles, but after 24 hours they returned to normal.[10] Oleocanthal inhibits the enzymatic activity of mammalian target of rapamycin (mTOR) with an IC50 value of 708 nM.[11] Oleocanthal inhibits the growth of several breast cancer cell lines at low micromolar concentration in a dose-dependent manner. Oleocanthal treatment caused a marked downregulation of phosphorylated mTOR in metastatic breast cancer cell line (MDA-MB-231). These results strongly indicate that mTOR inhibition is at least one of the factors of the reported anticancer and neuroprotective ...
In order to hydroxylate L-tryptophan, the cofactor tetrahydrobiopterin (THB) must first react with oxygen and the active site iron of tryptophan hydroxylase. This mechanism is not well understood, but two mechanisms have been proposed: 1. A slow transfer of one electron from the THB to O2 could produce a superoxide which could recombine with the THB radical to give 4a-peroxypterin. 4a-peroxypterin could then react with the active site iron (II) to form an iron-peroxypterin intermediate or directly transfer an oxygen atom to the iron. 2. O2 could react with the active site iron (II) first, producing iron (III) superoxide which could then react with the THB to form an iron-peroxypterin intermediate. Iron (IV) oxide from the iron-peroxypterin intermediate is selectively attacked by a double bond to give a carbocation at the C5 position of the indole ring. A 1,2-shift of the hydrogen and then a loss of one of the two hydrogen atoms on C5 reestablishes aromaticity to furnish ...
... is an ingredient in the common bronchodilator drug aminophylline, where it serves to solubilize the active ingredient theophylline. Ethylenediamine has also been used in dermatologic preparations, but has been removed from some because of causing contact dermatitis.[10] When used as a pharmaceutical excipient, after oral administration its bioavailability is about 0.34, due to a substantial first-pass effect. Less than 20% is eliminated by urinal excretion.[11] Ethylenediamine-derived antihistamines are the oldest of the five classes of first-generation antihistamines, beginning with piperoxan aka benodain, discovered in 1933 at the Pasteur Institute in France, and also including mepyramine, tripelennamine, and antazoline. The other classes are derivatives of ethanolamine, alkylamine, piperazine, and others (primarily tricyclic and tetracyclic compounds related to phenothiazines, tricyclic antidepressants, as well as the cyproheptadine-phenindamine family) ...
