[a] Radioligand displacement from hAT2R in membranes from HEK‐293 cells overexpressing hAT2R (assay 1). N=6 for C38 and 40, N=2 for all other. [b] Inhibition of radioligand binding from hAT1R expressed in HEK‐293 cells (assay 1). [c] Radioligand displacement from AT2R in pig uterus membrane.29 [d] Radioligand displacement from hAT2R expressed in HEK‐293 cells (assay 2). [e] Radioligand displacement from hAT1R expressed in HEK‐293 cells, ligands were not active on hAT1R at the concentrations tested (assay 2). N=9.
