36,39–41 A reduction in the fibrin content of thrombi formed in the P-selectin/ PSGL-1 inhibition is a treatment whose target does not involve the inhibition of the coagulation cascade, but the inhibition of inflammation. Different compounds have already been tested in our laboratory, with efficacy similar to enoxaparin. P-selectin inhibition is a promising therapeutic approach because it: 1.

In ischemic stroke patients, plasma P-selectin concentration was reported to be highly correlated to plasminogen activator inhibitor-1 activity and tissue plasminogen activator activity. Structure. P-selectin is found in endothelial cells and platelets where it is stored in Weibel-Palade bodies and α-granules, respectively.

Mechanisms for increasing synthesis of P-selectin are suggested by its presence on the apical surface of endothelial cells in human tissues with chronic or allergic inflammation.16-18 Indeed, TNF-α, IL-1β, or LPS increases expression of P-selectin mRNA and protein in murine endothelial cells in vitro and in vivo.10,19,20 Transient activation of the murine P-selectin gene requires the Consequently, P-selectin inhibition might have a beneﬁcial effect on survival of cancer patients, by attenuating both hematogenous metastasis and thromboembolic compli-cations. Unfractionated heparin (UFH ) and low molecular weight heparins are commonly used for the prevention and treat- For example, P-selectin inhibitors reduce platelet aggregation, prolong heart allograft survival, decrease vein injury from thrombosis, and reduce acute pancreatitis in murine model [45] [46][47][48].

36,39–41 A reduction in the fibrin content of thrombi formed in the The anti-P-selectin aptamer inhibited the adhesion of sickle RBCs and leukocytes to endothelial cells by 90% and 80%, respectively. The anti-P-selectin aptamer also increased microvascular flow velocities and reduced the leukocyte rolling flux. GlycoMimetics has granted Pfizer exclusive worldwide rights to develop and commercialize GMI-1070, a rationally designed glycomimetic inhibitor of E-, L- and P-selectin, for vaso-occlusive crisis Since P-selectin is a component of the membrane of platelet alpha and dense granules, and as degranulation is widely believed to be synonymous with activation, it therefore follows that increased expression of this molecule at the platelet surface reflects activation 9,10 Of further interest is the report that nitric oxide (NO) is a regulator of P-selectin expression as inhibitors of NO synthase increased P-selectin expression. 11 This may be clinically important as Minamino et al. 12 2005-08-01 · The small molecule inhibitor of P-selectin (PSI-697; Wyeth Research, Cambridge, MA) is an orally available noncarbohydrate and nonantibody inhibitor of P selectin.
