Anti-diarrheal therapeutic potential of diminazene aceturate stimulation of the ACE II/Ang-(1-7)/Mas receptor axis in mice: A trial study.

The angiotensin (Ang) II converting enzyme (ACE II) pathway has recently been shown to be associated with several beneficial effects on the body, especially on the cardiac system and gastrointestinal tract. ACE II is responsible for converting Ang II into the active peptide Ang-(1-7), which in turn binds to a metabotropic receptor, the Mas receptor (MasR). Recent studies have demonstrated that Diminazene Aceturate (DIZE), a trypanosomicide used in animals, activates the ACE II pathway.

Novel Ocellatin Peptides Mitigate LPS-induced ROS Formation and NF-kB Activation in Microglia and Hippocampal Neurons.

Cutaneous secretions of amphibians have bioactive compounds, such as peptides, with potential for biotechnological applications. Therefore, this study aimed to determine the primary structure and investigate peptides obtained from the cutaneous secretions of the amphibian, Leptodactylus vastus, as a source of bioactive molecules. The peptides obtained possessed the amino acid sequences, GVVDILKGAAKDLAGH and GVVDILKGAAKDLAGHLASKV, with monoisotopic masses of [M + H] = 1563.

Efficacy of a phenol derivative, isopropyl vanillate, as an anti-inflammatory agent: A new small molecule inhibitor of COX and neutrophil migration.

Inflammation is the response of the body to noxious stimuli such as infections, trauma, or injury. Experimental studies have shown that vanillic acid has anti-inflammatory effects. The objective of this study was to investigate the anti-inflammatory and antipyretic properties of the derivative of vanillic acid, isopropyl vanillate (ISP-VT), in mice.

Lactobacillus reuteri DSM 17938 Protects against Gastric Damage Induced by Ethanol Administration in Mice: Role of TRPV1/Substance P Axis.

This study aimed to evaluate the effect of DSM 17938 (DSM) on ethanol-induced gastric injury, and if its possible mechanism of action is related to inhibiting the transient receptor potential vanilloid type 1 (TRPV1). We evaluated the effect of supplementing 10⁸ CFU•g body wt•day of DSM on ethanol-induced gastric injury. DSM significantly reduced the ulcer area (1.

Evidence that d-cysteine protects mice from gastric damage via hydrogen sulfide produced by d-amino acid oxidase.

Hydrogen sulfide (HS) is a signaling molecule in the gastrointestinal tract. HS production can derive from d-cysteine via various pathways, thus pointing to a new therapeutic approach: delivery of HS to specific tissues. This study was designed to evaluate the concentration and effects of HS (generated by d-amino acid oxidase [DAO] from d-cysteine) in the gastric mucosa and the protective effects against ethanol-induced lesions in mice.

Anti-diarrhoeal therapeutic potential and safety assessment of sulphated polysaccharide fraction from Gracilaria intermedia seaweed in mice.

Sulphated polysaccharides extracted from algae have been extensively studied for their diverse biological activities. Thus, the purpose of this study was to evaluate the chemical composition, the anti-diarrhoeal effect and acute toxicity of a sulphated polysaccharide fraction obtained from Gracilaria intermedia (SP-Gi). Initially, the FT-IR of SP-Gi revealed to be an agaran with sulphation at C-6 of the l-galactosyl residues.

Carvacrol reduces irinotecan-induced intestinal mucositis through inhibition of inflammation and oxidative damage via TRPA1 receptor activation.

Intestinal mucositis is an inflammatory process occurring in the intestinal mucosa and is a common side effect of irinotecan hydrochloride (CPT-11) based anticancer regimens. The transient receptor potential cation channel, subfamily A, member 1 (TRPA1) receptor is highly expressed in the intestinal mucosa and has the ability to identify cell damage signaling indicates its possible association with intestinal mucositis. Carvacrol is an agonist of the TRPA1 receptor and has anti-inflammatory properties.
