Abstract

Gal-PUGNAc (see picture), a highly selective inhibitor for beta-hexosaminidases HEXA and HEXB is cell-permeable and modulates the activity of HEXA and HEXB in tissue culture, increasing ganglioside GM2 levels. Gal-PUGNAc should allow the role of these Enzymes to be studied at the cellular level without generating a complex chemical phenotype from concomitant inhibition of O-GlcNAcase.
