Biological Activity
|
α adrenergic receptor |
The racemic compound and its enantiomers show high and apparently equal affinity for subtypes of α1-adrenoceptors with Ki values in the low nanomolar range, and showed potent antagonism of α1-adrenoceptors in isolated tissues, with the enantiomers approximately equipotent to the racemate at each α1-adrenoceptor subtype. At α2b sites, (R)-Terazosin binds less potently than either the (S)-Terazosin or racemate[1].
