Abstract
BACKGROUND
Histone deacetylase (HDAC) inhibition has been found to be effective in the treatment of inflammatory bowel disease. Previous studies have reported that Cinnamyl sulfonamide hydroxamate derivatives possess non-selective HDAC inhibition.
OBJECTIVE
The present study was designed to screen three selected Cinnamyl sulfonamide hydroxamate derivatives, NMJ-1, NMJ-2, and NMJ3, for in vitro anti-inflammatory response by assessing the expression of pNF-κB in lipopolysaccharide (LPS)-induced inflammatory changes on RAW 264.7 cells, and in vivo anti-inflammatory response in acetic acid (AA) and 2.4-dinitrochlorobenzene (DNCB)-induced colitis models in Wistar rats.
METHOD
AA-induced colitis was produced in Wistar rats by intra-colonic administration of 1 ml AA. DNCBinduced colitis was produced by spraying 250 μL DNCB in acetone (20g/L) on the nape of the rats for 14 days, followed by the intracolonic administration on day 15. Drugs were administered for three days after the induction of colitis.
RESULTS
In vitro anti-inflammatory effect was observed by NMJ1 and NMJ2 through a significant decrease in pNF-κB overexpression-induced by LPS. Similar effect was observed in anti-colitis response by NMJ2 in both models by reversing the colitis-induced changes in length, weight, anti-oxidant profile and histopathology of the colon.
CONCLUSION
NMJ2 was found to be most effective among the tested compounds as an anti-inflammatory agent in both in vitro and in vivo inflammatory studies.
