Low anticoagulant heparin targets multiple sites of inflammation, suppresses heparin-induced thrombocytopenia, and inhibits interaction of RAGE with its ligands.

Narayanam V Rao, Brian Argyle, Xiaoyu Xu, Paul R Reynolds, Jeanine M Walenga, Margaret Prechel, Glenn D Prestwich, Robert B MacArthur, Bradford B Walters, John R Hoidal, Thomas P Kennedy,

While heparin has been used almost exclusively as a blood anticoagulant, important literature demonstrates that it also has broad anti-inflammatory activity. Herein, using low anti-coagulant 2-O,3-O-desulfated heparin (ODSH), we demonstrate that most of the anti-inflammatory pharmacology of heparin is unrelated to anticoagulant activity. ODSH has low affinity for anti-thrombin III, ... Read more >>

J Mocco, Corbett E Shelton, Paulina Sergot, Andrew F Ducruet, Ricardo J Komotar, Marc L Otten, Sergei A Sosunov, Robert B Macarthur, Thomas P Kennedy, E Sander Connolly,

<h4>Objective</h4>Inflammatory cascades play a significant role in progressive neurological injury after transient cerebral ischemia. It has been demonstrated that heparin, a potent anticoagulant, also possesses anti-inflammatory properties that diminish postreperfusion damage after stroke. However, the potential for heparin to induce hemorrhagic transformation of an infarct has deterred its use in ... Read more >>
