Effect of Syringic acid on antioxidant biomarkers and associated inflammatory markers in mice model of asthma

Abstract Preclinical Research& DevelopmentAsthma is termed as the induction of chronic inflammation in the airway lumen of lungs due to accumulation of inflammatory cells which affects normal breathing process. Prolonged accumulation of inflammatory cells leads to oxidative stress and suppression of antioxidant activities. Therefore, in our present investigation, a potential phenolic compound, Syringic acid was tested for the suppression of inflammatory markers toward an antiasthmatic activity in ovalbumin (OVA) ‐induced asthmatic mice model. As a result, the Syringic acid treatment was found to suppress the inflammatory cells; eosinophil, neutrophil, macrophage, lymphocyte, and other inflammatory markers including IL‐4, IL‐5, IL‐13, and TNF‐α in the BALF of OVA‐induced asthmatic mice. Similarl y, IgE levels were significantly reduced in the blood serum of Syringic acid treated mice groups. In this context, the IFN‐γ levels were found enhanced in the BALF of Syringic acid treated asthmatic mice groups, expressing an anti‐inflammatory response. Enzymatic and nonenzymatic antioxidants s uch as SOD, CAT, and GSH levels were found high in the Syringic acid treatment than the asthmatic control group, which depicts the antioxidant response of Syringic acid on asthmatic groups. Intriguingly, the ROS, NO2, NO3, and MDA levels were inhibited in the BALF of Syringic acid treated mice groups. The airway hyper ‐reactivity (AHR) was comparatively normal in the Syr...
