the ic50 values for 2-chloroadenosine , adenosine , l-n6-phenylisopropyladenosine and d-n6-phenylisopropyladenosine , n6-cyclohexyladenosine and adenosine-5'-n-ethyl-carboxamide inhibition of [ 3h ] 2-chloroadenosine binding are in good agreement with the values obtained in studies of the ability of these compounds to inhibit adenylate cyclase , suggesting that [ 3h ] -2-chloroadenosine binding sites reported here are comparable to the adenosine a1 receptor site .
