1 Radioligand binding properties of the adenosine receptor ligands,[3H]‐1, 3‐dipropyl‐8‐
cyclopentylxanthine ([3H]‐DPCPX), and [3H]‐R‐phenylisopropyladenosine ([3H]‐R‐PIA) …

Radioligand binding to A 1 adenosine receptors at brain membranes from seven species
was investigated. The antagonist 8-cyclopentyl-1, 3-[3 H] dipropyl-xanthine ([3 H] DPCPX) …

The effects of guanine nucleotides on binding of 8‐cyclopentyl‐1, 3‐[3H] dipropylxanthine
([3H] DPCPX), a highly selective A1 adenosine receptor antagonist, have been investigated …

1 The pharmacological profile of adenosine A1 receptors in human, guinea‐pig, rat and
mouse brain membranes was characterized in a radioligand binding assay by use of the …

1 The binding of 1, 3‐[3H]‐dipropyl‐8‐cyclopentylxanthine ([3H]‐DPCPX), an antagonist
radioligand selective for adenosine A1 receptors, was studied in rat duodenum, colon …

A1 adenosine receptors were labeled in rat brain sections with the antagonist [3H] 8‐
cyclopentyl‐1, 3‐dipropylxanthine ([3H] DPCPX) and visualized at the light microscopic level …

Cyclopentyl-1, 3-dipropylxanthine (PD 116,948) is a very potent, very A 1-selective
adenosine antagonist, with a K i of 0.46 nM in 3 H-CHA binding to A 1 receptors in rat whole …
