GlcNAcstatin is a highly potent and competitive inhibitor of O-GlcNAcase (OGA) with Ki value of 4.4 nM for human OGA [1]. GlcNAcstatin is a synthetic GlcNAc-configured nagstatin derivative with a larger isobutanamido group on N8 and a phenethyl group on C2. It inhibited bacterial OGA with Ki value of 4.6 pM. For human OGA, GlcNAcstatin also showed a potent inhibition with Ki value of 4.4 nM. Besides that, GlcNAcstatin exerted inhibitory activity against human lysosomal Hex A/B with Ki value of 550 nM, suggesting that it is a selective inhibitor of OGA. In HEK293 cells, treatment of GlcNAcstatin at concentration of 20 nM resulted in increased cellular O-GlcNAc levels of many proteins. GlcNAcstatin also significantly prevented O-GlcNAc from binding to proteins in SH-SY5Y human neuroblastoma cell lysates [1, 2]. | [Uses]
GlcNAcstatin is a selective glucoimidazole-based bacterial O-GlcNAcase inhibitor with a Ki of 4.6 pM. GlcNAcstatin shows 100000-fold selectivity over HexA/B[1]. | [References]
