Heparan Sulfate Glucosamine 3-O-Sulfotransferase 3 is a sulfotransferase enzyme that plays a crucial role in the biosynthesis of heparan sulfate.

Heparanase 1, Human, is a biocatalyst essential in the novel biocatalysis technology, serving as a key enzyme. Enzyme engineering focuses on improving reaction kinetics, substrate selectivity, and the activity of these enzymes under extreme conditions (e.g., low or high pH). Additionally, introducing stimuli-responsiveness through modifications allows for dynamic control of enzyme activity.

OGT 2115 is an inhibitor of heparanase (IC50 = 0.4 µM), an enzyme that cleaves heparan sulfate into glucuronic acid (GlcUA) and N-acetylglucosamine (GlcNAc). OGT 2115 also showed antiangiogenic properties (IC50=1 μM).

Heparastatin is an inhibitor of heparanase.

Pro-xylane (Hydroxypropyl tetrahydropyrantriol) is a C-glycoside, a xylose derivative, that stimulates the production of glycosaminoglycans (GAGs) and heparan sulfate proteoglycans (HSPGs) and induces a higher deposition of proteins in basement membranes and dermal-epidermal junctions (DEJs). Pro-xylane is used to maintain skin elasticity and improve skin aging.

D-(+)-Xylose (Wood sugar) is an aldopentose - a monosaccharide containing five carbon atoms and an aldehyde functional group. It has chemical formula C5H10O5 and is 40% as sweet as sucrose. Xylose is also found in mucopolysaccharides of connective tissue and sometimes in the urine. Xylose is the first sugar added to serine or threonine residues during proteoglycan type O-glycosylation. Therefore xylose is involved in the biosythetic pathways of most anionic polysaccharides such as heparan sulphate and chondroitin sulphate. In medicine, xylose is used to test for malabsorption by administering a xylose solution to the patient after fasting. If xylose is detected in the blood and/or urine within the next few hours, it has been absorbed by the intestines. Xylose is said to be one of eight sugars which are essential for human nutrition, the others being galactose, glucose, mannose, N-acetylglucosamine, N-acetylgalactosamine, fucose, and sialic acid. . Xylose in the urine is a biomarker for the consumption of apples and other fruits.

Pixatimod (also known as PG-545) is a synthetic carbohydrate-modified heparan sulfate mimetic and a Toll-like receptor 9 (TLR9) agonist. It exhibits potential immunostimulatory, antitumor, and antiviral effects. Pixatimod effectively inhibits SARS-CoV-2 by disrupting the spike protein-ACE2 interaction. Additionally, it blocks various cancer-promoting processes such as cell proliferation, invasion, metastasis, angiogenesis, and epithelial-mesenchymal transition. These effects have demonstrated significant efficacy in numerous mouse cancer models, including about 30 xenograft models and 20 syngeneic models. Pixatimod has been tested in combination with several approved anticancer compounds, showing clinical potential when used with gemcitabine, paclitaxel, sorafenib, platinum compounds, and anti-PD-1 antibodies.

L-Iduronic acid sodium salt, a monosaccharide, is an essential component of glycosaminoglycans (GAGs) such as heparin, heparan sulfate, and dermatan sulfate.

NSC 12 is an orally active pan-FGF trap that inhibits FGF-dependent tumor cell proliferation, angiogenesis, and metastasis.NSC 12 binds FGF2 and interferes with its interaction with FGFR1, but does not affect the ability of FGF2 to bind heparin or heparan sulfate proteoglycans (HSPGs), with potential antitumor activity.NSC 12 also organizes several other FGF isoforms to form the HSPG/FGF/FGFR ternary complex.

Hemisurfen is a small molecule, surfen derivative with heparan sulfate antagonist properties.
