O-GlcNAcase-IN-2

O-GlcNAcase-IN-2 (compound 81) is an orally active, brain-penetrant inhibitor of O-GlcNAcase, demonstrating an IC50 value of 4.93 nM. It has shown potential in elevating protein O-GlcNAcylation levels and promoting phosphorylation of tau (p-Ser199, p-Thr205, p-Ser396) in an OA-impacted SH-SY5Y cell model. Additionally, O-GlcNAcase-IN-2 has been observed to ameliorate cognitive deficits in APP/PS1 mice, suggesting its potential utility in combating Alzheimer's disease (AD) .
