Figure 3.
Inhibition of radioligand binding by dendrimer nucleoside conjugates in membranes of CHO cells expressing the human A1 (A) and A3 (C) ARs and HEK-293 cells expressing the human A2AAR (B). Inhibition curves at three ARs are shown for the dendrimer-nucleoside conjugates 6 and 7, in which the linkage to an azide-derivatized dendrimer was formed by click cycloaddition, for the mixed nucleoside/nucleotide conjugate 8 and for the amide-linked nucleoside conjugate 12. Both 6 and 7 were highly selective for the hA3AR in comparison to the hA1 and hA2AARs.
