Phosphoramidate derivates as controlled-release prodrugs of l-Dopa

l-Dopa has continued to be a mainstay in the symptomatic treatment of Parkinson’s disease (PD). However, extensive peripheral metabolism, a short systemic circulation half-life and development of motor complications called dyskinesia prevents its long-term utilization as a PD therapeutic. Herein, we report a series of phosphoramidate derivatives of l-Dopa and controlled release of l-Dopa at pH 7.4 and 3. The kinetic data for the release of...
