the adenosine receptors in membranes prepared from rat ventral and dorsal lumbar spinal cord were characterized by comparing the binding characteristics of [ 3h ] 5'-n-ethylcarboxamide adenosine ( [ 3h ] neca ) , an agonist with nearly equal affinities at the a1 and a2 adenosine receptor subtypes , with those of [ 3h ] n6- [ ( r ) -1-methyl-2-phenylethyl ] adenosine ( [ 3h ] r-pia ) , an a1-selective agonist .
