Iteamine, o-aminobenzyl beta-D-glucopyranoside, is the first alkaloid to be isolated from Itea virginica. Itea is the sole plant source of D-psicose, a rare sugar likely to be a major dietary supplement. The structure of iteamine was established by NMR and confirmed by total synthesis. Iteamine and its galacto-analog (which was not found in Itea plants) showed no strong inhibition of any of the 15 glycosidases tested; unnatural galacto-iteamine was a weak inhibitor of chicken liver alpha-N-acetylgalactosaminidase.
