生物活性 |
(S)-Terazosin is an active S-enantiomer of Terazosin. (S)-Terazosin is a potent and high-affinityα-adrenoceptorantagonist withKivalues of 3.91 nM, 0.79 nM and 1.16 nM forα1a,α1bandα1d-adrenoceptor, respectively. (S)-Terazosin also has high-affinity forα2a,α2Bandα2c-adrenoceptor withKivalues of 729 nM, 3.5 nM and 46.4 nM, respectively[1]. |

IC50& Target |
Ki: 3.91 nM (α1a-adrenoceptor), 0.79 nM (α1b-adrenoceptor) and 1.16 nM (α1d-adrenoceptor); 729 nM (α2a-adrenoceptor), 3.5 nM (α2Ba-adrenoceptor) and 46.4 nM (α2c-adrenoceptor)[1] |

体外研究 (In Vitro) |
The racemic compound and its enantiomers show high and apparently equal affinity for subtypes of α1-adrenoceptors with Kivalues 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].
