An O-GlcNAcase-specific inhibitor and substrate engineered by the extension of the N-acetyl moiety.


A novel analogue of PUGNAc, a potent O-GlcNAcase inhibitor, was synthesized and analyzed as an inhibitor of O-GlcNAcase, hexosaminidase A, and hexosaminidase B. While PUGNAc does not demonstrate selective inhibition of these related enzymes, the extension of the acetyl moiety to the longer butyl chain provided a compound with depressed inhibition of O… (More)
