生物活性:
(S)-Terazosin is an active S-enantiomer of Terazosin. (S)-Terazosin is a potent and high-affinity α-adrenoceptor antagonist with Ki values of 3.91 nM, 0.79 nM and 1.16 nM for α1a, α1b and α1d-adrenoceptor, respectively. (S)-Terazosin also has high-affinity for α2a, α2B and α2c-adrenoceptor with Ki values of 729 nM, 3.5 nM and 46.4 nM, respectively.
体内研究:
(S)-Terazosin shows antagonism of at rat atrial α2B receptor with a pEC30 of 6.93. (s)-Terazosin shows antagonism of at rat vas deferens α1A and α2A receptor with pA2 values of 8.3 and 6.12, respectively.
体外研究:
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.
