Application

Heparin disaccharide I-H sodium salt has been used as a non-naphthalene, negatively charged, bivalent compound to test its ability to induce liquid-liquid phase separation (LLPS).

Biochem/physiol Actions

Heparin disaccharide is a bivalent compound with less hydrophobic nature. It elevates the cytosolic calcium (Ca2+) extrusion rate and may serve as a potential drug for the activation of Na+ /Ca2+ exchanger (NCX).

Heparin and heparan sulfate fragments, obtained by bacterial heparinase and heparitinases, bearing an unsaturation at C4-C5 of the uronic acid moiety, are able to produce up to 80% reduction of the cytosolic calcium of smooth muscle cell lines. Unsaturated disaccharides

Liquid-liquid phase separation (LLPS) of proteins that leads to formation of membrane-less organelles is critical to many biochemical processes in the cell. However, dysregulated LLPS can also facilitate aberrant phase transitions and lead to protein aggregation and disease. Accordingly, there
