Abstract

The present invention relates to O-GlcNAc hydrolase (OGA) inhibitors. The invention is also directed to pharmaceutical compositions comprising such compounds, to processes for preparing such compoundsand compositions, and to the use of such compounds and compositions for the prevention and treatment of disorders in which inhibition of OGA is beneficial, such as tauopathies, in particular Alzheimer's disease or progressive supranuclear palsy; and neurodegenerative diseases accompanied by a tau pathology, in particular amyotrophic lateral sclerosis or frontotemporal lobe dementia caused by C90RF72 mutations.

Description

technical field [0001] The present invention relates to O-GlcNAc hydrolase (OGA) inhibitor having the structure shown in formula (I) [0002] [0003] wherein these groups are as defined in the specification. The invention also relates to pharmaceutical compositions comprising such compounds, processes for the preparation of such compounds and compositions, and the use of such compounds and compositions for the prevention and treatment of disorders in which inhibition of OGA is beneficial, such disorders are, for example, tauopathies, especially Alzheimer's disease or progressive supranuclear palsy; and neurodegenerative diseases with tauopathology, especially amyotrophic lateral sclerosis or frontotemporal dementia caused by C9ORF72 mutations . Background technique [0004] O-GlcN acylation is a reversible modification of proteins in which N-acetyl-D-glucosamine residues are transferred to the hydroxyl groups of serine and threonine residues, resulting in O-GlcN acylat...
