The design and synthesis of novel adenosine agonists

The 2R and 2S-endo isomers of N6-(5,6-epoxynorborn-2-yl)adenosine have been synthesised and shown to be potent agonists for the A1 adenosine receptor. The 2S-endo isomer was equipotent to N6-cyclopentyladenosine and 10- to 12-fold more potent than the 2R-endo isomer.
