Summary of the results of human A3 AR docking of a selective A3 AR agonist, CI-IB-MECA (A), a nonselective, nonpurine AR antagonist, CGS15943 (B). Residues surrounding the putative binding site are shown [Gao et al., 2002a]. The residues in the double-squared box indicate identity among four subtypes of ARs and those in the single-squared box are conserved amino acids similarity among ARs. lntermolecular H-bonds are shown with arrows.
