APEC, An A2-Selective Adenosine Agonist, is a More Potent Locomotor Depressant Than N6-Cyclohexyladenosine

Abstract
The locomotor depressant effects of APEC are due to activation of central A2 adenosine receptors, while the depressant effects of NECA are dependent primarily on A1-receptor activation. A variety of potent A1-antagonists, including conjugates of the XAC, were screened as antagonists; 2-thio-CPX and CPT reversed effects of CHA, but not of APEC.
