Nystose is a tetrasaccharide with two fructose molecules linked via beta (1→2) bonds to the fructosyl moiety of sucrose.

D75-4590 is a β-1,6-Glucan inhibitor. As glucan is a major component of the cell wall, specifically β-1,6-Glucan, D75-4590 can fight fungal infections by inhibiting its synthetase.

N tau-methylhistamine is one of the histamine metabolites. N tau-methylhistamine in plasma and urine is a good parameter for histamine release and the determination of this histamine metabolite is generally less hampered by possible artifacts (due to basophil disrupture a very short half-life time or bacterial production) than determinations of histamine itself.
