ABSTRACT
Background: The present study was aimed at examining the effect of dehydrozingerone (DHZ), half analogue of curcumin which is the active constituent of turmeric (Curcuma longa) in the di‑nitrochlorobenzene (DNCB) induced model for inflammatory bowel disease (IBD). Materials and Methods: Male Wistar rats (200–220 g) were divided into four groups (n = 6). Chemical induction of IBD was done by sensitizing with 300 µL of 20 g/L of DNCB (in acetone) onto the nape of rats for 14 days followed by intra‑colonic instillation of 250 µL of DNCB (0.1% DNCB in 50% alcohol) solution on day 15. Rats in Group 1 (normal control) and Group 2 (DNCB control) were treated with vehicle. Rats in Group 3 were treated with DHZ (100 mg/kg, p.o.; 8 days) and Group 4 animals were treated with sulfasalazine (SS) (100 mg/kg, p.o.; 8 days). On 24th day, the rats were killed, colon removed and the macroscopic, biochemical, and histopathological evaluations were performed. Results: The levels of myeloperoxidase, thiobarbituric acid reactive substrate, and nitrite increased significantly (P < 0.05) in the DNCB group whereas reduced significantly in the DHZ and SS treated groups. Serum nitrite levels were found to be insignificant between the different groups. Interleukin‑6, tumor necrosis factor‑alpha level was significantly high in the DNCB group. Conclusion: These findings show that DHZ can be a promising molecule for the treatment of IBD.
