Thiamet G | O-GlcNAcase alpha 1 antagonist

Thiamet G (1009816-48-1) is a potent, selective inhibitor of O-GlcNAcase (K_i = 21 nM for human O-GlcNAcase). Increases levels of O-GlcNAc-modified proteins in cellular assays and in vivo. Suppresses phosphorylation of tau protein in rat cortex and hippocampus.¹ Stabilizes tau against aggregation and slows neurodegeneration.² Thiamet G prevents cognitive decline and amyloid plaque formation in bigenic tau/APP mutant mice.³ Active in vivo and blood brain barrier permeable.
