The P-selectin specificity of the STMC was defined by the anomeric linkage of the C-C bond. This STMC hexasaccharide is an effective inhibitor of P-selectin in vivo. We show that selective inhibition of heparanase attenuates metastasis in B16-BL6 melanoma cells, expressing high levels of this endoglycosidase, but has no effect on the metastasis of MC-38 carcinoma cells that express little or no heparanase activity.

It was noticed that P-selectin was positively correlated with DIC score, fibrinogen consumption, fibrinolysis (D-dimer), thrombin activation markers, and TFPI. Tissue factor pathway inhibitor was significantly correlated with fibrinolysis, DIC score, and prothrombin fragment 1+2.

However, this inhibitor was previously shown to be a potent inhibitor of E-selectin and a nonpotent inhibitor of P-selectin, with high concentrations needed to inhibit P-selectin . The necessity of using very high concentrations of GMI-1070 to achieve inhibition of P-selectin-mediated interactions of MM cells with the BM microenvironment limits the possibility to translate it into clinical In this review, we will highlight the various approaches taken toward the development of sLe x mimetics as antagonists of E‐ and P‐selectin, including the use of structural information about the selectins and their interactions with sLe x that have been revealed through the use of NMR, protein crystallography and molecular modeling. © 2002 Wiley Periodicals, Inc.

P-Selectin Inhibitor Binding P-selectin on the surface of the activated endothelium and platelet cells blocks interactions between endothelial cells, platelets, red blood cells, and leukocytes;

38 The findings of an improvement in spontaneous thrombolysis in animals in which P-selectin is inhibited by rPSGL-Ig are similar to results found in primate, porcine, and rat models of arterial and venous thrombosis using P … The P-selectin specificity of the STMC was defined by the anomeric linkage of the C-C bond. This STMC hexasaccharide is an effective inhibitor of P-selectin in vivo.

The ligand for P-selectin is the P-selectin glycoprotein ligand-1, or PSGL-1, which is expressed on the surface membranes of leukocytes. Richard Cummings and his team have set out to prevent an inflammatory response in the body by blocking P-selectin from being activated. In other words, they created a P-selectin inhibitor.

This STMC hexasaccharide is an effective inhibitor of P-selectin in vivo. We show that selective inhibition of heparanase attenuates metastasis in B16-BL6 melanoma cells, expressing high levels of this endoglycosidase, but has no effect on the metastasis of MC-38 carcinoma cells that express little or no heparanase activity.

In addition, the NH 2 47 amino acids were linked to an Fc portion of human IgG 1. of gastric and pancreatic cancer patients [18]. P-selectin signaling through its receptor on leukocytes, P-selectin glycoprotein ligand 1 (PSGL-1), induces the generation of tissue factor-positive, highly procoagulant microparticles [10,19].

2003-12-01 P-selectin, also called granule membrane protein 140, antigen CD62, or platelet activation dependent granule-external membrane protein (PADGEM), is a 140 kD adhesion molecule that mediates the interaction of stimulated endothelial cells or platelets to leukocytes in the vascular surface [ 18 Conclusions—The P-selectin inhibitor aptamer promoted iliac vein recanalization, preserved valve competency, and decreased vein wall fibrosis. The results of this work suggest that P-selectin inhibition maybe an ideal target in the treatment and prophylaxis of deep VT, warranting clinical trials. P‐selectin is a cell surface adhesion molecule that has a central role in mediating interactions between platelets and other cell types, such as leukocytes and the endothelium.

The therapeutic potential of P‐selectin antagonism has been demonstrated by the application of specific monoclonal antibodies that block P‐selectin and PSGL‐1 and are associated with reduced levels of platelet activation.9Indeed, P‐selectin‐blocking antibodies reduced arterial thrombosis, reperfusion injury, and infarct size in mice.16Recently small‐molecule antagonists have been developed that interact with P‐selectin and inhibit its function. A glycopeptide inhibitor of p-selectin for the treatment of sickle cell disease. Key Benefits. Blocks the activity of P-selectin with nM affinity.

As the EWVDV peptides inhibit the binding of an established glycoside ligand for P-selectin (sulfated Lewis A), it is conceivable that EWVDV interacts with or in close proximity to the actual carbohydrate recognition domain of P-selectin, without being a direct structural mimic of sialyl Lewis x.

of gastric and pancreatic cancer patients [18]. P-selectin signaling through its receptor on leukocytes, P-selectin glycoprotein ligand 1 (PSGL-1), induces the generation of tissue factor-positive, highly procoagulant microparticles [10,19]. Consequently, P-selectin inhibition might have a beneficial effect on survival of cancer patients, by In recent years, the development of potent P-selectin inhibitors has been the subject of extensive investigation and included mostly synthetic analogs of PSGL-1 and its sLe x moiety (reviewed by Lefer35), including sulfopeptides, which are based on the N-terminal domain of PSGL-1.29,36 However, it has been difficult to design P-selectin–specific antagonists from these parent compounds, because PSGL-1 and sLe x also display affinity for E-selectin and L-selectin.26,37,38 The peptides we P-selectin inhibitor Sickle Cell Disease Emerging Pipeline.
