    The anti-inflammatory properties of a heparin-like compound from the shrimp Litopenaeus vannamei are related. Besides reducing significantly (p < 0.001) the influx of inflammatory cells to injury site in a model of acute inflammation, shrimp heparin-like compound was able to reduce the matrix metalloproteinase (MMPs) activity in the peritoneal lavage of inflamed animals. Moreover, this compound also reduced almost 90% the activity of MMP-9 secreted by human activated leukocytes. Negligible anti-coagulant activities in aPPT assay and a poor bleeding potential make this compound a better alternative than mammalian heparin as a possible anti-inflammatory drug.
