Disclosed are promoieties of the following formula which can be used to form prodrugs of nitrogen-containing or hydroxyl-containing drug or a pharmaceutically active agent: (I) and pharmaceutical compositions comprising the prodrugs.
The present invention concerns prodrugs of opioid analgesics and pharmaceutical compositions containing such prodrugs. Methods for providing more consistent pain relief by increasing the bioavailability of the opioid analgesic with the aforementioned prodrugs are provided. The invention also provides for decreasing the adverse GI side effects of opioid analgesics.

was found that deuterium labeling causes an isotopeeffect on the elution of labeled amines on RPLC but has no effect on HILIC LC. However, 13C-dimethylation does not show any isotopeeffect on either RPLC or HILIC LC, indicating that 13C-labeling is a preferred approach for relative quantification of amine-containing metabolites in different samples. The isotopicallylabeled 35 amine-containing analogues
