Several types of exposures can cause acute or chronic inflammatory reactions in the lungs often leading to asthma, pulmonary fibrosis, chronic obstructive pulmonary disease (COPD), acute lung injury, lung cancer, and other deleterious health outcomes. Current therapy, with inhaled or oral glucocorticoids, successfully targets inflammation but also produces adverse effects that limit their enthusiastic use. Accordingly, the need remains for interventions that are safer and more effective. Nitrated fatty acids (NFAs) are highly electrophilic and are produced endogenously by non-enzymatic reactions of nitric oxide with conjugated unsaturated fatty acids. The literature indicates that NFAs are detected in humans at the nanomolar range and are produced more robustly under inflammatory conditions. Recent studies on novel NFAs report antiinflammatory, antioxidant, and antifibrotic effects, while also acting as partial agonists of peroxisome proliferator-activated receptor-gamma (PPAR-γ). Furthermore, these functions of NFAs occur via reversible electrophilic alkylation of cysteine residues and regulation of antiinflammatory, antioxidant signaling through modulation of transcription factors, including nuclear factor E2-related factor 2 (Nrf2), PPAR-γ, and NF-κB. Here, we review and update the role of NFA signaling mechanisms and their therapeutic potential in various lung diseases. As NFAs display strong electrophilic interaction with multimechanistic pathways, they can be considered promising drug candidates for challenging lung diseases.

亲电子硝化脂肪酸是炎性和纤维化性肺病的潜在治疗候选物。

几种类型的接触可引起肺部的急性或慢性炎症反应,通常导致哮喘,肺纤维化,慢性阻塞性肺疾病(COPD),急性肺损伤,肺癌和其他有害健康的后果。目前的吸入或口服糖皮质激素疗法可以成功地针对炎症,但也会产生不利于其积极使用的副作用。因此,仍然需要更安全,更有效的干预措施。硝化脂肪酸(NFA)具有高度亲电性,是由一氧化氮与共轭不饱和脂肪酸的非酶促反应内生产生的。文献表明,NFA在人的纳摩尔范围内被检测到,并在炎症条件下更牢固地产生。新型NFA的最新研究表明抗炎,抗氧化剂和抗纤维化作用,同时还作为过氧化物酶体增殖物激活的受体-γ(PPAR-γ)的部分激动剂。此外,NFA的这些功能是通过半胱氨酸残基的可逆亲电烷基化和通过调节转录因子(包括核因子E2相关因子2(Nrf2),PPAR-γ和NF-κB)调节抗炎,抗氧化信号而发生的。在这里,我们审查和更新NFA信号传导机制的作用及其在各种肺部疾病中的治疗潜力。由于NFA与多种机理之间显示出很强的亲电相互作用,因此可以将它们视为挑战性肺疾病的有前途的候选药物。NFA的这些功能是通过半胱氨酸残基的可逆亲电烷基化和通过调节转录因子(包括核因子E2相关因子2(Nrf2),PPAR-γ和NF-κB)调节抗炎,抗氧化信号传导来实现的。在这里,我们审查和更新NFA信号传导机制的作用及其在各种肺部疾病中的治疗潜力。由于NFA与多种机理之间显示出很强的亲电相互作用,因此可以将它们视为挑战性肺疾病的有前途的候选药物。NFA的这些功能是通过半胱氨酸残基的可逆亲电烷基化和通过调节转录因子(包括核因子E2相关因子2(Nrf2),PPAR-γ和NF-κB)调节抗炎,抗氧化信号传导来实现的。在这里,我们审查和更新NFA信号传导机制的作用及其在各种肺部疾病中的治疗潜力。由于NFA与多种机理之间显示出很强的亲电相互作用,因此可以将它们视为挑战性肺疾病的有前途的候选药物。我们回顾并更新了NFA信号传导机制的作用及其在各种肺部疾病中的治疗潜力。由于NFA与多种机理之间显示出很强的亲电相互作用,因此可以将它们视为挑战性肺疾病的有前途的候选药物。我们回顾并更新了NFA信号传导机制的作用及其在各种肺部疾病中的治疗潜力。由于NFA显示出与多种途径的强亲电相互作用,因此可以将它们视为挑战性肺疾病的有前途的候选药物。
