N-Substituted 5-amino-1-hydroxymethyl-cyclopentanetriols: A new family of activity promotors for a GM1-gangliosidosis related human lysosomal β-galactosidase mutant

Add time:08/23/2019    Source:sciencedirect.com

From 1,2;3,4-di-O-isopropylidene-α-D-galactopyranose, a series of highly functionalized (hydroxymethyl)cyclopentanes was easily available. In line with reports by Reymond and Jäger on similar structures, these amine containing basic carbasugars are potent inhibitors of β-D-galactosidases and, for the first time, could be shown to act as pharmacological chaperones for GM1-gangliosidosis-associated lysosomal acid β-galactosidase mutant R201C, thus representing a new structural type of pharmacological chaperones for this lysosomal storage disease.
