Abstract: Disclosed are adenosine derivatives, methods for the synthesis thereof, and pharmaceutical compositions for the prevention and treatment of inflammatory diseases, comprising the same as an active ingredient. The adenosine derivatives have high binding affinity and selectivity for adenosine receptors, especially for A3 adenosine receptors and act as A3 adenosine receptor antagonists, and exhibit anti-inflammatory activity. Thus, the adenosine derivatives are useful in the prevention and treatment of inflammatory diseases.
