Gal‐PUGNAc (see picture), a highly selective inhibitor for β‐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.
