6-hydroxy-FAD is the dominant cofactor of H. insolens Cellobiose dehydrogenases. the activity of Cellobiose dehydrogenases containing 6-hydroxy-FAD is lower than that of the enzyme reconstituted with normal FAD.

5-trans Prostaglandin D2 is a prostaglandin D2 receptor agonist.

5-CNAC disodium is an orally active enhancer of absorption, with no pharmacological activity on its own. 5-CNAC disodium can significantly enhance the absorption efficiency of the drug (such as Salmon calcitonin) when administered together with it in the gastrointestinal tract. 5-CNAC disodium binds reversibly and non-covalently to peptide drugs, protecting them from degradation by gastrointestinal enzymes, increasing their lipid solubility, promoting passive transcellular absorption, and not damaging the integrity of the intestinal epithelium. 5-CNAC disodium can be used in the research of adjuvants for orally administered peptide agents.
