scyllo-Inositol
Chemical compound / From Wikipedia, the free encyclopedia
scyllo-Inositol, also called scyllitol, cocositol, or quercinitol, is a chemical compound with formula C6H12O6, one of the nine inositols, the stereoisomers of cyclohexane-1,2,3,4,5,6-hexol. The molecule has a ring of six carbon atoms, each bound to one hydrogen atom and one hydroxyl group (–OH); if the ring is assumed horizontal, the hydroxyls lie alternatively above and below the respective hydrogens.

scyllo-Inositol is a naturally occurring carbohydrate, specifically a sugar alcohol. It occurs in small amounts in the tissues of humans and other animals,[4] certain bacteria,[5] and more abundantly in some plants.[5][6]
Around 2000, scyllo-inositol attracted attention as a possible treatment for neurodegenerative disorders such as Alzheimer's. For this use it received the codes AZD-103 and ELND005.[7]
