prunus armeniaca l. (apricot) is a tree cultivated in different parts of the world. apricot kernel as a good dietary supplement has shown antioxidant, anti-inflammatory and other pharmacologic properties which suggest that it may be functional as an anticolitis agent. in this study we evaluated the effects of apricot kernel extract and oil on ulcerative colitis in rats. rats were fasted for 36 ...
objectives: iron chelators, such as maltol and kojic acid, have antioxidant and anti-inflammatory properties. they may have beneficial effects on inflammatory bowel disease (ibd) because iron can develop and aggravate inflammation in ibd. in the present study, the effect of selected iron chelators and anti-oxidants were evaluated on a model of trinitrobenzene sulfonic acid (tnbs)-induced coliti...
Two highly efficient protocols for the production of bis-coumarins under solvent-free conditions have been introduced. The reaction of 4-hydroxycoumarin (2 eq.) with arylaldehydes (1 eq.) using phthalimide-N-sulfonic acid (PhtSA) or isatin-N-sulfonic acid (IsSA), as solid-acid catalysts, afforded the mentioned compounds with good to excellent yields in short times.Briefly, we have introduced tw...
Inflammatory bowel disease is associated with inducible nitric oxide synthase (iNOS) expression, oxidative and nitrosative stress, and leukocyte infiltration in the colon. Here, we investigate the effects of the selective iNOS-inhibitor (S)-2-amino-(1-iminoethylamino)-5-thiopentanoic acid (GW274150) on the development of experimental colitis induced by dinitrobenzene sulfonic acid. When compare...
