Potent and selective aminocyclopentane-derived inhibitors of human O-N-acetyl-beta-d-glucosaminidase (OGA) have been developed for the treatment of Alzheimer's disease. Compound 13, for example, showed nanomolar OGA inhibition and 92,000-fold selectivity over human HexB. It was non-toxic and increased protein O-GlcNAcylation in murine neural cell culture, providing new alternatives for tauopathies treatment.
