McN-A-343, a muscarinic agonist, reduces inflammation and oxidative stress in an experimental model of ulcerative colitis.

Aim: The aim of the present study was to investigate the anti-inflammatory response mediated of the M1 muscarinic acetylcholine receptor (mAChR) during experimental colitis.

Material And Methods: After the induction of 6% acetic acid colitis, mice were treated with McN-A-343 0.5, 1.

Polysaccharides derived from Morinda citrifolia Linn reduce inflammatory markers during experimental colitis.

Ethnopharmacological Relevance: There are many reports of pharmacological activities of extracts and fractions of different vegetable-derived products in the scientific literature and in folk medicine. Ethnopharmacological use of these products by various communities continues to be extensively explored, and they account for more than half of all medications used worldwide. Polysaccharides (PLS) extracted from plants such as Morinda Citrifolia Linn present therapeutic potential in treatment of inflammatory bowel diseases (IBD) such as ulcerative colitis (UC).

Proteins from Plumeria pudica latex exhibit protective effect in acetic acid induced colitis in mice by inhibition of pro-inflammatory mechanisms and oxidative stress.

Latex proteins from P. pudica (LPPp) have anti-inflammatory activity. In the present study, LPPp was evaluated to protect animals against inflammatory ulcerative colitis (UC).

Chemical structure and anti-inflammatory effect of polysaccharide extracted from Morinda citrifolia Linn (Noni).

Polysaccharides extracted from plants are very promising molecules in the field of pharmacotherapy. Knowing this, the aim of this study was to extract, characterize and evaluate the action of the polysaccharide of Morinda citrifolia Linn (Noni-PLS) in biological models of inflammatory processes. The characterization tests shown that sample refers to a heteropolysaccharide composed mainly of homogalacturonan and rhamnogalacturonan.

Riparin B, a Synthetic Compound Analogue of Riparin, Inhibits the Systemic Inflammatory Response and Oxidative Stress in Mice.

The aim of our study was to evaluate the anti-inflammatory, anti-nociceptive, and anti-oxidant action of Riparin B in vivo. We performed experiments in which we induced paw edema by carrageenan and other mediators, carrageenan-induced peritonitis and the level of myeloperoxidase (MPO) activity, pro-inflammatory cytokines (TNF-α and IL-1β), malondialdehyde (MDA) acid, and glutathione (GSH) from the peritoneal fluid. We also performed behavior tests such as acetic acid-induced writhing, formalin-induced linking, and the hot plate test.

Gabapentin, a synthetic analogue of gamma aminobutyric acid, reverses systemic acute inflammation and oxidative stress in mice.

The aim of this study was to investigate the potential anti-inflammatory and anti-oxidant effects of gabapentin (GBP) in mice. The anti-inflammatory and anti-oxidant effects were evaluated using various mediators that induce paw edema, peritonitis model, myeloperoxidase (MPO) activity, proinflammatory cytokine levels, glutathione (GSH) consumption, and malondialdehyde (MDA) production in mice. Pretreatment of mice with GBP (1 mg/kg) significantly reduced carrageenan or dextran-induced paw edema (P<0.

Sulfated-polysaccharide fraction extracted from red algae Gracilaria birdiae ameliorates trinitrobenzenesulfonic acid-induced colitis in rats.

Objectives: The aim of this study was to evaluate the protective effect of the sulfated-polysaccharide (PLS) fraction extracted from the seaweed Gracilaria birdiae in rats with trinitrobenzenesulfonic acid (TNBS)-induced colitis.

Methods: In the experiments involving TNBS-induced colitis, rats were pretreated with polysaccharide extracted from G. birdiae (PLS: 30, 60 and 90 mg/kg, 500 μL p.

Polysaccharide isolated from Agardhiella ramosissima: chemical structure and anti-inflammation activity.

The sulfated polysaccharide (PLS) fraction of Agardhiella ramosissima was characterized by microanalysis, infrared spectroscopy, NMR and gas-liquid-chromatography-mass-spectrometry. The main constituent of PLS was the ι carrageenan. The monosaccharide composition of the PLS showed galactose, 3,6-anhydrogalactose and 6-O-methylgalactose.
