WebHeparin is a polysaccharide-based anticoagulant agent, which is widely used in surgery and blood transfusion. However, overdosage of heparin may cause severe side effects such as bleeding and low blood platelet count. Currently, there is only one clinically licensed antidote for heparin: protamine sulfate, which is known to provoke adverse effects. In this work, we … WebHeparin has an immediate onset of action and peak anticoagulant activity in 20–30 ... substrates displaying heparin-binding peptides can facilitate the long-term culture of …
WebSubcutaneously deliverable heparin-peptide nanogranules that allow for long-lasting heparin bioavailability in the circulatory system, while enabling on-demand activation of heparin's anticoagulant effects in the thrombus microenvironment, are reported.

WebNov 2, 2011 · The heparin-binding characteristics of the various purified peptides were investigated with high-salt elution of the peptide from a heparin column . The heparin-binding activity of the peptides was reported to be p1 > p6 > p4 > p5 = p3 > p7 > p2 and was dependent on the net charge (see table in Synthesis).
WebN values were in the range of 0.19–0.27, suggesting that 4–5 molecules of peptide were bound to a single molecule of heparin (one peptide/10 saccharides) and the effect was independent of the temperature. 37 The much weaker binding affinity mostly suggests the presence of a non-specific binding mode resulted from hydrophobic interaction. WebMar 18, 2024 · Herein, we designed an antioxidant heparin-mimetic peptide hydrogel (K16, KYKYEYEYAGEGDSS-4Sa) for radiation-induced skin injury repair. First, K16 peptide can self-assemble into a hydrogel with a three-dimensional mesh-like porous nanofiber structure, which can provide certain physical support for skin repair like extracellular matrix (ECM).
