Note: Aldo, aldosterone; DOC, 11-deoxycorticosterone; Dex, dexamethasone; Reichstein's compound S, 11-deoxycortisol; Reichstein's compound E, cortisone. + and 0 indicate activation or lack of activation, respectively, by each ligand to induce transactivational activity at concentrations of ≤ 10-7 M. N.A. indicates that the data are not available. Data from previous studies are indicated by the citations following the receptor type. The MR response to dexamethasone is excluded because of the confounding dexamethasone paradox [53].

1Activity at >10-7 M;

2Disagreement between previous studies;

3Possible low activation at 10-6 M
