synthetic and uptake resistant adenosine analogues had the same effect as adenosine and the order of potency of these was : 5'-n-ethylcarboxamide adenosine greater than l-n6-phenylisopropyl adenosine ( l-pia ) = n6-cyclohexyladenosine = 2-chloroadenosine greater than adenosine greater than d-n6-phenylisopropyladenosine ( d-pia ) .
