Desmethylbellidifolin From Gentianella acuta Ameliorate TNBS-Induced Ulcerative Colitis Through Antispasmodic Effect and Anti-Inflammation
Desmethylbellidifolin (DMB) is a natural xanthone extracted from Gentianella acuta, which is used as the antidiarrhea drug in traditional Mongolian medicines. It remains unknown whether DMB can ameliorate ulcerative colitis (UC). In this study, trinitrobenzenesulfonic acid (TNBS)-induced colitis rat...

description | Desmethylbellidifolin (DMB) is a natural xanthone extracted from Gentianella acuta, which is used as the antidiarrhea drug in traditional Mongolian medicines. It remains unknown whether DMB can ameliorate ulcerative colitis (UC). In this study, trinitrobenzenesulfonic acid (TNBS)-induced colitis rats were treated with G. acuta extract (GAE) or DMB for 10 days. Body weight, food and water intake, rectal bleeding score, diarrhea score, and histopathological parameters were measured. Rat colon were collected to determine myeloperoxidase, nitric oxide levels, and inflammatory cytokines expression. In addition, the role of DMB on lipopolysaccharide stimulated RAW264.7 cell inflammatory response and intestine smooth muscle contraction was determined. The results showed that GAE and DMB treatment could significantly alleviate TNBS-induced UC. Colon morphological alteration, nitric oxide level, and inflammatory cytokines level, such as nitric oxide synthase, interleukin-6, tumor necrosis factor-α, and cyclooxygenase-2, were decreased. In addition, DMB attenuated lipopolysaccharide-induced nitric oxide release and proinflammatory cytokine expression in RAW264.7 cells. In isolated mice intestinal tissue, DMB also reduced the intestine smooth muscle spontaneous contraction and inhibited KCl, acetylcholine, BaCl(2), or histamine-induced intestine smooth muscle active tension, while the active frequency was unaffected. Our results demonstrated that GAE and its active constituent DMB could inhibit TNBS-induced UC, reducing inflammatory response and alleviate colon muscle spasm, suggesting that DMB may be a good candidate for subsequent development as a multitargeting drug for UC treatment. |
