RESUMEN
Asthma is a lung condition characterized by impaired respiratory function and an apparent infiltration of inflammatory cells. Chalcones are substances that have attracted considerable interest in the disciplines of pharmaceutical chemistry and drug discovery due to their diverse biochemical processes, such as antioxidant, anti-inflammatory, anticancer, antibacterial, and others, but whether they can be used in asthma treatment has yet to be investigated. This study aimed to investigate the immunomodulatory effect of 4 hydroxychalcone (4-HC) against allergic asthma in mice. In this research, we investigated how 4-HC affected asthmatic behavior, leukocyte infiltration, histopathological alterations, oxidative stress, immunoglobulin E (IgE) production, and airway inflammation. Moreover, ELISA and immunohistochemistry (IHC) were used to measure the expression of Nrf2 and GPx4. 4-HC treatment significantly decreased lung oxidative stress, inflammatory cell infiltration, and IgE levels. According to our findings, we imply that 4-HC may be utilized as an anti-asthmatic agent through the upregulation of Nrf2/GPx4 signaling pathway.
