The present invention concerns the field of neurodegenerative diseases, and in particular relates to compounds, pharmaceutical compositions and their uses in the protection of neuronal cells from inflammation and from oxidative stress in the early stage of Parkinson's Disease as well as in Alzheimer's Disease.

The present invention concerns the field of neurodegenerative diseases, and in particular relates to compounds, pharmaceutical compositions and their uses in the protection of neuronal cells from inflammation and from oxidative stress in the early stage of Parkinson's Disease as well as in Alzheimer's Disease.

Disclosed herein are compounds represented by Structural Formula I:

##STR00001##

or a pharmaceutically acceptable salt thereof. Values for the variables in Structural Formula I are described herein. The compounds can be used to modulate (e.g., inhibit) N-acylethanolamine hydrolyzing acid amidase (NAAA) and thereby treat a variety of diseases, disorders and conditions mediated by NAAA, such as a gastrointestinal motility disorder, irritable bowel syndrome, an inflammatory bowel disorder, neuroinflammation, nicotine addiction, cancer, opioid dependence, analgesia, chemotherapy-induced neuropathic pain and pain. Also disclosed herein are compositions and methods including compounds of Structural Formula I, or a pharmaceutically acceptable salt thereof.
