摘要: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 A 3 adenosine receptors and act as A 3 adenosine receptor antagonists, and exhibit anti-inflammatory activity. Thus, the adenosine derivatives are useful in the prevention and treatment of inflammatory diseases.

摘要:The present invention provides a method for the preparation of 5-azacytidine, wherein 5-azacytidine is represented by the structure: n n n n n n n n n n The method involves the silylation of 5-azacytosine, followed by the coupling of silylated 5-azacytosine to a protected β-D-ribofuranose derivative. The coupling reaction is catalyzed by trimethylsilyl trifluoromethanesulfonate (TMS-Triflate).
