ABSTRACT:
The invention relates to a method of improving oral drug absorption of adenosine analogues by the use of 2′-methoxy adenosine pro-drugs and to the use of these pro-drugs as medicaments. The invention further relates to compounds that are pro-drugs of adenosine receptor agonists, and to their use as therapeutic compounds, in particular as analgesic or anti-inflammatory compounds, or as disease modifying antirheumatic drugs (DMARDs), and to methods of preventing, treating or ameliorating pain or inflammation using these compounds.
