Evidence for a multivalent effect in inhibition of sulfatases involved in lysosomal storage disorders (LSDs)

Two newly synthesized nonavalent polyhydroxylated pyrrolidine iminosugars are the first examples of multivalent inhibitors of GALNS and IDS lysosomal enzymes, whose deficiency leads to Morquio A syndrome and Hunter disease, respectively, and pave the way to a pharmacological chaperone or stabilizing enzyme therapy for these LSDs.
