Structural characterization of a sulfated polysaccharide from Gracilariadomingensis and potential anti-inflammatory and antinociceptive effects.
Seaweeds are natural sources of sulfated polysaccharides (SPs), biopolymers with remarkable pharmacological properties, including biological actions capable of attenuating components of the inflammatory process such as edema, cytokines, cell migration and pain. Our results confirm that SPs obtained from Gracilaria domingensis (SP-GD) are agarans, primarily composed of residues of β-d-galactopyranose 6-sulfate and 3,6-anhydro-α-l-galactopyranose. Specifically, SP-GD at a dose of 10 mg/kg was effective in significantly reducing paw edema induced by carrageenan or histamine, serotonin, bradykinin, 48/80 and prostaglandin E2. SP-GD (10 mg/kg) was also able to reduce neutrophil migration and the activity of the myeloperoxidase enzyme in carrageenan-induced peritonitis, as well as conserve glutathione concentration and reduce malondialdehyde levels in the animals' peritoneal fluid. Furthermore, it showed antinociceptive action in the abdominal writhing test induced by acetic acid and in the paw licking test induced by formalin. Thus, the results obtained allow us to infer that SPs extracted from G. domingensis at a dose of 10 mg/kg have anti-inflammatory effects by reducing neutrophil migration and modulating the activity of vasoactive mediators and antinociceptive effects by acting, at least in part, through a peripheral mechanism dependent on the negative modulation of inflammatory mediators.
期刊介绍:
Carbohydrate Research publishes reports of original research in the following areas of carbohydrate science: action of enzymes, analytical chemistry, biochemistry (biosynthesis, degradation, structural and functional biochemistry, conformation, molecular recognition, enzyme mechanisms, carbohydrate-processing enzymes, including glycosidases and glycosyltransferases), chemical synthesis, isolation of natural products, physicochemical studies, reactions and their mechanisms, the study of structures and stereochemistry, and technological aspects.
Papers on polysaccharides should have a "molecular" component; that is a paper on new or modified polysaccharides should include structural information and characterization in addition to the usual studies of rheological properties and the like. A paper on a new, naturally occurring polysaccharide should include structural information, defining monosaccharide components and linkage sequence.
Papers devoted wholly or partly to X-ray crystallographic studies, or to computational aspects (molecular mechanics or molecular orbital calculations, simulations via molecular dynamics), will be considered if they meet certain criteria. For computational papers the requirements are that the methods used be specified in sufficient detail to permit replication of the results, and that the conclusions be shown to have relevance to experimental observations - the authors'' own data or data from the literature. Specific directions for the presentation of X-ray data are given below under Results and "discussion".
