ABSTRACT
Certain low-molecular-weight substrate analogs act both as in vitro competitive inhibitors of lysosomal hydrolases and as intracellular enhancers (chemical chaperones) by stabilization of mutant proteins. In this study, we performed oral administration of a chaperone compound N-octyl-4-epi-beta-valienamine to G(M1)-gangliosidosis model mice expressing R201C mutant human beta-galactosidase. A newly developed neurological scoring system was used for clinical assessment. N-Octyl-4-epi-beta-valienamine was delivered rapidly to the brain, increased beta-galactosidase activity, decreased ganglioside G(M1), and prevented neurological deterioration within a few months. No adverse effect was observed during this experiment. N-Octyl-4-epi-beta-valienamine will be useful for chemical chaperone therapy of human G(M1)-gangliosidosis.
