Abstract
The present invention provides non-anticoagulant sulfated or sulfonated polysaccharides (NASPs), which accelerate the blood clotting process. Also provided are pharmaceutical formulations comprising a NASP of the invention in conjunction with a pharmaceutically acceptable excipient and, in various embodiments, these formulations are unit dosage formulations. The invention provides a NASP formulation, which is orally bioavailable. Also provided are methods for utilizing the compounds and formulations of the invention to promote blood clotting in vivo as therapeutic and prophylactic agents and in vitro as an aid to studies of the blood clotting process.

18. A method of inhibiting Tissue Factor Pathway Inhibitor (TFPI) activity in a biological sample, the method comprising combining the biological sample with a sufficient amount of a non-anticoagulant sulfated or sulfonated polysaccharide (NASP) to inhibit the TFPI activity, wherein the NASP is a member selected from α

20. A method of measuring acceleration of blood clotting by a non-anticoagulant sulfated or sulfonated polysaccharide (NASP) in a biological sample, wherein the NASP is a member selected from α
- -cyclodextrin, β
-cyclodextrin, melezitose, stachyose, raffinose, maltotriose, maltotetraose, maltopentaose, cellotriose, cellotetraose, cellopentaose, xylan, icodextrin and 6-carboxylcodextrin, the method comprising;
a) combining the biological sample with a composition comprising the NASP; and
b) measuring the clotting time of the biological sample, c) comparing the clotting time of the biological sample to the clotting time of a corresponding biological sample not exposed to the NASP, wherein a decrease in the clotting time of the biological sample exposed to the NASP is indicative of a NASP that accelerates the clotting time.
