CD44 Ligand

Hyaluronic acid sodium (MW 200-1560) is a biopolymer composed of repeating disaccharide units, with a molecular weight of 200-1560. Hyaluronic acid sodium is a major component of the extracellular matrix (ECM). It is synthesized on the plasma membrane. Hyaluronic acid sodium exerts its effects by binding to receptors CD44 and RHAMM. Hyaluronic acid sodium activates PI3K-Akt signaling. Hyaluronic acid sodium also enhances cell invasion and angiogenesis by promoting or stimulating the binding of proteolytic MMP-9 to the cell surface. Elevated hyaluronic acid levels are associated with tumor cell growth, adhesion, migration, invasion, and angiogenesis in digestive system cancers. Hyaluronic acid sodium is involved in tissue remodeling and rapid cell proliferation in several physiological processes, including embryonic morphogenesis and wound healing. Hyaluronic acid sodium can be used as a regulator of cancer-associated lymphangiogenesis. Hyaluronic acid sodium can be used as a drug delivery carrier for sodium butyrate, enhancing its anti-proliferative activity against breast cancer cell lines. Hyaluronic acid sodium can lubricate the corneal endothelium. Hyaluronic acid sodium can improve tissue hydration and enhance the resistance of cells to mechanical damage. Hyaluronic acid sodium has been conjugated with antibodies to ensure that the active compound continues to exert its effects at the site of inflammation. Hyaluronic acid sodium can be used in research in the fields of osteoarthritis, ophthalmology, cosmetic dermatology, oncology, and liver diseases.

Hyaluronic acid, low endotoxin (Hyaluronan, low endotoxin) is a biopolymer composed of repeating disaccharide units containing low levels of endotoxin. Hyaluronic acid is a major component of the extracellular matrix (ECM). It is synthesized on the plasma membrane. Hyaluronic acid exerts its effects by binding to receptors CD44 and RHAMM. Hyaluronic acid activates PI3K-Akt signaling. Hyaluronic acid also enhances cell invasion and angiogenesis by promoting or stimulating the binding of proteolytic MMP-9 to the cell surface.

3-Methylbenzene-1,2-diamine (Tolylene-2,3-diamine) is a CD44 hyaluronic acid-binding domain ligand, with a K_d of 8.5 mM for hCD44 HABD and a K_d of 6.4 mM for mCD44 HABD. 3-Methylbenzene-1,2-diamine acts as a non-inhibitor that does not interfere with the binding of CD44 HABD to polymeric hyaluronic acid in vitro.
