Dailah HG. Therapeutic Potential of Small Molecules Targeting Oxidative Stress in the Treatment of Chronic Obstructive Pulmonary Disease (COPD): A Comprehensive Review. Molecules 2022; 27:molecules27175542. [PMID: 36080309 PMCID: PMC9458015 DOI: 10.3390/molecules27175542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/21/2022] [Accepted: 08/25/2022] [Indexed: 12/02/2022] Open
Abstract
Chronic obstructive pulmonary disease (COPD) is an increasing and major global health problem. COPD is also the third leading cause of death worldwide. Oxidative stress (OS) takes place when various reactive species and free radicals swamp the availability of antioxidants. Reactive nitrogen species, reactive oxygen species (ROS), and their counterpart antioxidants are important for host defense and physiological signaling pathways, and the development and progression of inflammation. During the disturbance of their normal steady states, imbalances between antioxidants and oxidants might induce pathological mechanisms that can further result in many non-respiratory and respiratory diseases including COPD. ROS might be either endogenously produced in response to various infectious pathogens including fungi, viruses, or bacteria, or exogenously generated from several inhaled particulate or gaseous agents including some occupational dust, cigarette smoke (CS), and air pollutants. Therefore, targeting systemic and local OS with therapeutic agents such as small molecules that can increase endogenous antioxidants or regulate the redox/antioxidants system can be an effective approach in treating COPD. Various thiol-based antioxidants including fudosteine, erdosteine, carbocysteine, and N-acetyl-L-cysteine have the capacity to increase thiol content in the lungs. Many synthetic molecules including inhibitors/blockers of protein carbonylation and lipid peroxidation, catalytic antioxidants including superoxide dismutase mimetics, and spin trapping agents can effectively modulate CS-induced OS and its resulting cellular alterations. Several clinical and pre-clinical studies have demonstrated that these antioxidants have the capacity to decrease OS and affect the expressions of several pro-inflammatory genes and genes that are involved with redox and glutathione biosynthesis. In this article, we have summarized the role of OS in COPD pathogenesis. Furthermore, we have particularly focused on the therapeutic potential of numerous chemicals, particularly antioxidants in the treatment of COPD.

Abstract
Cigarette smoking has been associated with high risk of neurological diseases such as stroke, Alzheimer's disease, multiple sclerosis, etc., The present study was designed to evaluate the restorative effects of Sesbania grandiflora (S. grandiflora) on oxidative damage induced by cigarette smoke exposure in the brain of rats. Adult male Wistar-Kyoto rats were exposed to cigarette smoke for a period of 90 days and consecutively treated with S. grandiflora aqueous suspension (SGAS, 1000 mg/kg body weight per day by oral gavage) for a period of 3 weeks. The levels of protein carbonyl, nitric oxide, and activities of cytochrome P450, NADPH oxidase and xanthine oxidase were significantly increased, whereas the levels of total thiol, protein thiol, non-protein thiol, nucleic acids, tissue protein and the activities of Na(+)/K(+)-ATPase, Ca(2+)-ATPase and Mg(2+)-ATPase were significantly diminished in the brain of rats exposed to cigarette smoke as compared with control rats. Also cigarette smoke exposure resulted in a significant alteration in brain total lipid, total cholesterol, triglycerides and phospholipids content. Treatment of SGAS is regressed these alterations induced by cigarette smoke. The results of our study suggest that S. grandiflora restores the brain from cigarette smoke induced oxidative damage. S. grandiflora could have rendered protection to the brain by stabilizing their cell membranes and prevented the protein oxidation, probably through its free radical scavenging and anti-peroxidative effect.

Abstract
Objectives. The aim of this study was to evaluate if xanthine oxidase and myeloperoxidase levels quantitation method may alternate routine culture method, which takes more time in the diagnosis of urinary tract infections. Material and Methods. Five hundred and forty-nine outpatients who had admitted to Clinic Microbiology Laboratory were included in the study. The microorganisms were identified by using VITEK System. The urine specimens that were negative from the quantitative urine culture were used as controls. The activities of MPO and XO in spot urine were measured by spectrophotometric method. Results. Through the urine cultures, 167 bacteria were isolated from 163 urine specimens; 386 cultures yielded no bacterial growth. E. coli was the most frequent pathogen. In infection with E. coli both XO and MPO levels were increased the most. The sensitivity, specificity, positive predictive value, and negative predictive value for XO were 100%, 100%, 100%, and 100%, respectively. These values for MPO were 87%, 100%, 100%, and 94%, respectively. Conclusion. These data obtained suggest that urine XO and MPO levels may be new markers in the early detection of UTI.

Abstract
Cigarette smoke (CS) exposure is unquestionably the most frequent cause of emphysema in the United States. Accelerated pulmonary endothelial cell (EC) apoptosis is an early determinant of lung destruction in emphysema. One of the pathogenic causes of emphysema is an alveolar oxidant and antioxidant imbalance. The enzyme xanthine oxidoreductase (XOR) has been shown to be a source of reactive oxygen species (ROS) in a multitude of diseases (S. Sakao et al., FASEB J.21, 3640-3652; 2007). The contribution of XOR to CS-induced apoptosis is not well defined. Here we demonstrate that C57/bl6 mice exposed to CS have increased pulmonary XOR activity and protein levels compared to filtered-air-exposed controls. In addition, we demonstrate that primary pulmonary human lung microvascular endothelial cells exposed to cigarette smoke extract undergo increased rates of caspase-dependent apoptosis that are reliant on XOR activity, ROS production, and p53 function/expression. We also demonstrate that exogenous XOR is sufficient to increase p53 expression and induce apoptosis, suggesting that XOR is an upstream mediator of p53 in CS-induced EC apoptosis. Furthermore, we show that XOR activation results in DNA double-strand breaks that activate the enzyme ataxia telangiectasia mutated, which phosphorylates histone H2AX and upregulates p53. In conclusion, CS increases XOR expression, and the enzyme is both sufficient and necessary for p53 induction and CS-induced EC apoptosis.

Abstract
The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger is an important kitchen spice and also possess a myriad health benefits. The rhizomes have been used since antiquity in the various traditional systems of medicine to treat arthritis, rheumatism, sprains, muscular aches, pains, sore throats, cramps, hypertension, dementia, fever, infectious diseases, catarrh, nervous diseases, gingivitis, toothache, asthma, stroke and diabetes. Ginger is also used as home remedy and is of immense value in treating various gastric ailments like constipation, dyspepsia, belching, bloating, gastritis, epigastric discomfort, gastric ulcerations, indigestion, nausea and vomiting and scientific studies have validated the ethnomedicinal uses. Ginger is also shown to be effective in preventing gastric ulcers induced by nonsteroidal anti-inflammatory drugs [NSAIDs like indomethacin, aspirin], reserpine, ethanol, stress (hypothermic and swimming), acetic acid and Helicobacter pylori-induced gastric ulcerations in laboratory animals. Various preclinical and clinical studies have also shown ginger to possess anti-emetic effects against different emetogenic stimuli. However, conflicting reports especially in the prevention of chemotherapy-induced nausea and vomiting and motion sickness prevent us from drawing any firm conclusion on its effectiveness as a broad spectrum anti-emetic. Ginger has been shown to possess free radical scavenging, antioxidant; inhibition of lipid peroxidation and that these properties might have contributed to the observed gastroprotective effects. This review summarizes the various gastroprotective effects of ginger and also emphasizes on aspects that warranty future research to establish its activity and utility as a gastroprotective agent in humans.

Abstract
Inflammation frequently decreases local anesthetic effects, especially in dental anesthesia in patients with pulpitis and periodontitis. The pharmacokinetics and the mode of action of local anesthetics are closely associated with the hydrophobic interactions between these drugs and lipid bilayers that change the membrane physicochemical property, fluidity. A lipid oxidant, peroxynitrite, is produced by inflammatory cells, and it may act on nerve cell membranes and affect anesthetic efficacy. With respect to this speculated action, we addressed whether peroxynitrite acted on membrane-constituting lipids to decrease the membrane interactivity of lidocaine. Membrane fluidity changes were determined by measuring the fluorescence polarization of liposomes prepared with different phospholipids. Peroxynitrite (0.1-50 microM) rigidified nerve-cell model membranes consisting of unsaturated phospholipids, as well as liposomal membranes consisting of 1,2-dioleoylphosphatidylcholine and 1-stearoyl-2-arachidonylphosphatidylcholine, but peroxynitrite did not rigidify 1, 2-dipalmitoylphosphatidylcholine liposomal membranes. The pretreatment of nerve-cell model membranes with peroxynitrite (0.1-50 microM) decreased the membrane-fluidizing effects of lidocaine (5.0 mg x ml(-1)) to 63%-86% of the control (not treated with peroxynitrite) depending on the peroxynitrite concentration. As one of the mechanisms of the local anesthetic failure associated with inflammation, inflammatory peroxynitrite may affect local anesthesia by acting on membrane-constituting unsaturated phospholipids.

Abstract
Sesbania grandiflora, commonly known as "sesbania" and "agathi," is widely used in Indian traditional medicine for the treatment of a broad spectrum of diseases. In the present study, we evaluated the possible protective effect of an aqueous suspension of S. grandiflora (ASSG) leaves against cigarette smoke-induced oxidative damage in rats. Adult Wistar-Kyoto rats were exposed to cigarette smoke for a period of 90 days and treated with ASSG (1,000 mg/kg of body weight/day, p.o) for a period of 3 weeks. The levels of protein carbonyl and activities of cytochrome P450, NADPH oxidase, and xanthine oxidase were significantly increased, whereas the levels of total thiol, protein thiol, non-protein thiol, nucleic acids, and tissue protein were significantly reduced in lung, liver, kidney, and heart of cigarette smoke-exposed rats as compared with control rats. Plasma nitric oxide levels, measured as nitrite plus nitrate, were significantly increased in cigarette smoke-exposed rats when compared to the control rats. The above changes were ameliorated to near control in the treatment group. These results suggest that supplementation with ASSG reversed the cigarette smoke-induced oxidative damage in rats through its antioxidant potential. These results provide further support for the traditional use of S. grandiflora in the treatment of smoke-related diseases.

The pharmokinetic limitations of antioxidant treatment for COPD. Pulm Pharmacol Ther 2007; 21:370-9. [PMID: 18054260 DOI: 10.1016/j.pupt.2007.10.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2007] [Revised: 10/03/2007] [Accepted: 10/06/2007] [Indexed: 01/08/2023]
Abstract
COPD is one of the leading causes of death worldwide and the age-adjusted mortality for this disease has risen significantly over the past 30 years. Current pharmacological treatments do not effectively address the inflammatory and apoptotic mechanisms that are critical in the development of this disease. Thus, despite therapy, patients typically experience a continued deterioration of their clinical status. Markers of oxidative stress are increased in the lungs of COPD patients and epidemiologic and animal studies indicate that antioxidants can protect the lungs from the damaging effects of cigarette smoke. To date, however, clinical trials of antioxidants for COPD have yielded disappointing results. This review discusses the pharmokinetic factors that limit the use of exogenous antioxidants as a treatment for this disease. In addition, it addresses strategies to overcome these limitations so that the beneficial properties of antioxidants can be translated into effective therapies for COPD patients.

Abstract
The aim of this study was to investigate the effects of chronic ethanol intake and cigarette smoke exposure on rat kidney. The animals were divided into four experimental groups: (1) the control group (C), (2) the ethanol group (E), (3) the cigarette smoke group (CS), and (4) the cigarette smoke plus ethanol group (CS+E). Rats in E, CS and CS+E groups were treated with ethanol and/or cigarette smoke for 6 months. The animals were killed and the kidneys were removed to determine the activity of xanthine oxidase (XO), myeloperoxidase (MPO) and the levels of nitric oxide (NO). Histopathological and immunohistochemical analysis were performed in kidney tissues. The activity of XO/g protein were 2.8 +/- 0.3, 5.2 +/- 0.3, 3.2 +/- 0.1, and 7.4 +/- 0.7 U for C, E, CS and CS+E groups, respectively. In groups E, and CS+E, the XO values were significantly higher than in group C (P < 0.05). The increase in XO activity of CS was not significantly different from group C (P > 0.05). There was a significant increase in XO activity of group CS+E as compared to CS and E groups (P < 0.05), and also a significant difference in XO activity between E and CS was observed (P < 0.05). The activity of MPO/g protein were 13.5 +/- 0.6, 16.2 +/- 1.1, 14.7 +/- 1.1, 23.8 +/- 0.9 U for C, E, CS, and CS+E groups, respectively. While MPO activity of kidneys from group CS+E were significantly higher as compared to C, CS, and E groups (P < 0.05), there was no significant difference among the groups of C, CS, E (P > 0.05). The levels of NO/g wet tissue were 347.7 +/- 8.5, 261.1 +/- 4.8, 329.8 +/- 5.6, and 254.2 +/- 3.8 nmol for C, E, CS, and CS+E groups, respectively. In groups of E and CS+E, the NO values were significantly lower than that of group C animals (P < 0.05). Although we detected lower NO levels in the E and CS+E groups than in CS group (P < 0.05), a significant difference in NO levels between CS+E and E groups was not observed. In the histopathological analysis of the kidney slices, severe degenerations in kidney tissues of group CS, E, CS+E were observed. Generally, the histological changes in kidney of CS+E and E groups were more severe than those observed in CS alone. While we observed a strong immunoreactivity for anti-nitrotyrosine antibody in kidneys of group CS+E, examination of sections from rat kidneys in group E revealed moderate staining. On the other hand, group CS had very little immunostaining. There was no immunostaining in group C. We concluded that chronic ethanol administration and cigarette smoke exposure may cause oxidative and nitrosative stress which lead to rat kidney damage.

Abstract
Tobacco smoking has been causally linked to the development of chronic obstructive pulmonary disease. It has been reported that the reactive oxygen species (ROS)- generating enzyme xanthine dehydrogenase/oxidase (XO) is increased in smoking-related stomach ulcers and that gastric mucosal damage caused by tobacco smoke can be blocked by the XO inhibitor allopurinol. In order to test the hypothesis that tobacco may cause the upregulation of XO in the lung, cultured rat pulmonary microvascular endothelial cells were exposed to tobacco smoke condensate (TSC). TSC at a concentration of 20 microg/mL significantly upregulated XO activity after 24 h of exposure. Longer exposure (1 week) to a lower concentration of TSC (2 microg/mL) also caused an increase in XO activity. Unlike hypoxia, TSC treatment did not alter the phosphorylation of XO. However, TSC treatment increased XO mRNA expression and the XO gene promoter activity. Furthermore, actinomycin D blocked the activation of XO by TSC. In conclusion, our results indicate that tobacco smoke condensate causes upregulation of XO transcription and activity.
