Аннотация
BACKGROUND: Asthma is a chronic airway disease characterized by immunological dysregulation that causes sustained inflammation, leading to aberrant airway narrowing and mucus production. Isopimpinellin (IP) is a naturally occurring furanocoumarin, generated by an association of coumarin and a furan ring, possessing antifungal, antibacterial, and antioxidant properties; however, its potential in asthma treatment has not been investigated. This study sought to evaluate the anti-inflammatory and antioxidant effects of IP in an ovalbumin (OVA)-induced murine model of asthma.
METHODS: Mice were grouped into four groups (n = 8 per group): control, OVA, and IP-treated (35 and 70 mg/kg). At the end of the experiment, lung oxidative stress, inflammation, and histopathological changes were evaluated.
RESULTS: IP treatment significantly ameliorated airway oxidative stress by decreasing the concentration of malondialdehyde (MDA) and increasing the levels of antioxidants, including glutathione (GSH), catalase (CAT), and glutathione peroxidase (GPx); reduced inflammatory cell infiltration; mitigated histological changes; and decreased levels of IL-4, IL-13, and IgE. Additionally, IP prevented NF-κB phosphorylation. This study is the first examination of the anti-asthmatic properties of IP in allergic asthma in murine models.
CONCLUSION: Our data indicate that IP may function as an anti-asthmatic medication via regulating oxidative stress and inflammation.
