Abstract

Official abstract text for this publication.

This disclosure relates to the use of uridine diphosphate (UDP) derivatives, salts and/or prodrugs thereof for the treatment of inflammatory conditions (e.g., psoriasis) and glaucoma, to prodrugs of UDP derivatives, compositions comprising therapeutically effective amounts of those prodrugs of the UDP derivatives and methods of using those prodrugs for treating various disorders including, e.g., neuronal disorders, including neurodegenerative disorders (e.g., Alzheimer's disease, Parkinson's disease) and traumatic CNS injury, pain, Down Syndrome (DS), glaucoma, and inflammatory conditions, e.g., psoriasis and rheumatoid arthritis.
