| Description | (R)-Terazosin is an active R-enantiomer of Terazosin and a potent antagonist of α1-adrenoceptor [(α1a, α1b, and α1d-adrenoceptor] with Ki values of 6.51 nM, 1.01 nM, and 1.97 nM, respectively). |
| Targets&IC50 | α1D-adrenoceptor:1.97 nM (Ki), α1A-adrenoceptor:6.51 nM (Ki), α1B-adrenoceptor:1.01 nM (Ki) |
| In vitro | (R)-Terazosin exhibits low affinity for α2a, α2B, and α2c-adrenoceptors (Ki of 3.85 μM, 0.33 μM, and 0.37 μM, respectively). It may serve as a useful probe for exploring the functional roles of adrenoceptor subtypes in various tissues. |
| In vivo | (R)-Terazosin demonstrates antagonism at rat atrial α2B receptor (pEC30: 5.69) and at rat vas deferens α1A and α2A receptors (pA2: 7.5 and 5.31, respectively). |
