Implication

Randomized trial investigates antioxidant and anti-inflammatory effects in a rat model of ulcerative colitis, suggesting potential protective benefits.

Key Points

This study examines the antioxidant and anti-inflammatory properties of N-acetylcysteine (NAC), Tiron, and their combination in ulcerative colitis.
In vitro assays included ligand–ligand docking and antioxidant activity tests.
In vivo model used male Wistar rats with induced colitis via acetic acid after NAC, Tiron, or combination pre-treatment.
Histological analysis assessed colonic damage and biochemical markers for inflammation and oxidative stress.
NAC–Tiron combination exhibited greater antioxidant activity than the single compounds in DPPH radical scavenging.
In vivo, treatments reduced colonic damage, inflammatory cell infiltration, and oxidative stress indicators.
C-reactive protein and free iron levels decreased without adverse effects on other biochemical measures.
