Aim: Investigating a novel compound, DMPNP, for treating colitis in mice, a key issue in inflammatory bowel diseases (IBD).Methods: Mice with induced colitis received DMPNP (50, 100, 150 mg/kg) or sulfasalazine (SUL), evaluated via tissue assessment, Disease Activity Index (DAI), myeloperoxidase (MPO), nitric oxide (NO) levels and cytokine analysis.Results: DMPNP significantly reduced colitis symptoms, inflammation and oxidative stress at higher doses, with marked improvements in DAI, MPO, NO and cytokines, comparable to SUL results.Conclusion: DMPNP shows potent anti-inflammatory and immunomodulatory properties, indicating potential as an IBD therapeutic. Further clinical trials are suggested to validate these outcomes.
