Di-N-acetyl-D-lactosamine (DNL) is a sugar that is found in the mammalian tissues and can be used as a lectin to specifically bind to glycoproteins. It has been shown to have specificities for enteritis, and can be used to detect or analyze the sequences of oligosaccharides. DNL has been immobilized on silica gel, which was then reacted with lectins, such as concanavalin A, wheat germ agglutinin, and soybean agglutinin. This process allows for the detection of high-mannose-type oligosaccharides.

2-Hydroxypropyl-b-cyclodextrin is a water-soluble drug that is chemically stable in aqueous media. It has been shown to be safe for use in the eye, with no significant side effects. 2-Hydroxypropyl-b-cyclodextrin has been shown to have anti-inflammatory properties and will not cause hemolytic activity. 2-Hydroxypropyl-b-cyclodextrin binds to retinoic acid receptors, which are found on cells of the corneal surface and in human spermatozoa. The binding of retinoic acid inhibits the production of enzymes that break down retinoids and prevents cell proliferation. This agent also interacts with other cellular components such as proteins, lipids, carbohydrates, nucleic acids, and hormones.

Candesartan N-glucuronide is a metabolite of candesartan. It is produced by human UDP-glucuronosyltransferase, which belongs to the subfamily of uridine diphosphate (UDP)-glucuronosyltransferases. Candesartan N-glucuronide inhibits angiotensin II receptor type 1 (AT1) and has minimal effects on angiotensin II receptor type 2 (AT2). Candesartan N-glucuronide binds to the AT1 receptor and blocks its activation by angiotensin II. This binding inhibits the uptake of sodium ions into cells and causes an increase in potassium ion secretion, leading to vasodilation. Candesartan N-glucuronide also induces the expression of cytochrome P450 3A5, which results in increased metabolism of drugs such as paclitaxel.

GD1b ganglioside (shown as ammonium salt) is one of the major gangliosides in neuronal and glial membranes. It has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with its two sialic acids linked α2,3/α2,8 to the inner galactose residue, and ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009). GD1b ganglioside acts as a receptor for BK virus, as well as for heat-labile LTII-a toxin, produced by enteropathogenic E. coli. GD1b ganglioside also interacts with tetanus neurotoxin (TeNT) and is crucial for its entry into cells (Kolter, 2012). The functional significance of ammonia in the brain is not yet fully understood: see (Modi 1994).
