Correlation between the potencies of A2a-adenosine receptor ligands as inhibitors of FITC-APEC and radioligand binding. The K1 (nM) values assessed by inhibition of FITC-APEC binding (ordinate) by A2a-adenosine receptor ligands were related to K1 values found using [3H]NECA binding (abscissa). FITC-APEC inhibition data (means) were obtainted from the values in Fig. 4 and Table I. [3H]NECA inhibition data were from the report by Bruns et al. [23]. The following compounds were used in the graph: NECA, DPMA, 2-CADO, CHA, R-PIA, CV 1808, and theophylline. The correlation coefficient for inhibition of FITC-APEC binding versus [3H]NECA binding was r = 0.97 (P = 0.0003).
