摘要:
A compound of formula (I), or a pharmaceutically acceptable salt thereof: ##STR1## wherein X is halogen, perhalomethyl, cyano, C.sub.1-6 -alkoxy, C.sub.1-6 -alkylthio, or C.sub.1-6 -alkylamino; andR.sup.1 is selected from N-bonded heterocycles.The compound with the greatest ability to discriminate between the A1 and A2 adenosine receptors is 2-chloro-N-[4-phenoxy-1-piperidinyl]adenosine. These adenosine derivatives are useful as anti-convulsants.
摘要:
